              Because of the flexible filtering system, you might encounter a situation where one filter prevents another from doing its job.

When this happens, you will need to rearrange the order in which filters get executed.

              Filters are executed from top-to-bottom. You can use the weight column to rearrange them: heavier filters \'sink\' to the bottom.

                  +

                  If you know how to script in PHP, Drupal gives you the power to embed any script you like. It will be executed when the page is viewed and dynamically embedded into the page. This gives you amazing flexibility and power, but of course with that comes danger and insecurity if you don\'t write good code. If you are not familiar with PHP, SQL or with the site engine, avoid experimenting with PHP because you can corrupt your database or render your site insecure or even unusable! If you don\'t plan to do fancy stuff with your content then you\'re probably better off with straight HTML.

                  +

                  Remember that the code within each PHP item must be valid PHP code - including things like correctly terminating statements with a semicolon. It is highly recommended that you develop your code separately using a simple test script on top of a test database before migrating to your production environment.

                  +

                  Notes:

                  • You can use global variables, such as configuration parameters, within the scope of your PHP code but remember that global variables which have been given values in your code will retain these values in the engine afterwards.
                  • register_globals is now set to off by default. If you need form information you need to get it from the "superglobals" $_POST, $_GET, etc.
                  • You can either use the print or return statement to output the actual content for your item.
                  +

                  A basic example:

                  +

                  You want to have a box with the title "Welcome" that you use to greet your visitors. The content for this box could be created by going:

                  +
                  +  print t("Welcome visitor, ... welcome message goes here ...");
+
                  +

                  If we are however dealing with a registered user, we can customize the message by using:

                  +
                  +  global $user;
+  if ($user->uid) {
+    print t("Welcome $user->name, ... welcome message goes here ...");
+  }
+  else {
+    print t("Welcome visitor, ... welcome message goes here ...");
+  }
+
                  +

                  For more in-depth examples, we recommend that you check the existing Drupal code and use it as a starting point, especially for sidebar boxes.

+Menus are a collection of links (menu items) used to navigate a website. The menu module provides an interface to control and customize the powerful menu system that comes with Drupal.  Menus are primarily displayed as a hierarchical list of links using Drupal\'s highly flexible blocks feature. Each menu automatically creates a block of the same name. By default, new menu items are placed inside a built-in menu labelled %navigation, but administrators can also create custom menus.
                          
+
                          Drupal themes generally provide out-of-the-box support for two menus commonly labelled %primary-links and %secondary-links. These are sets of links which are usually displayed in the header or footer of each page (depending on the currently active theme). Any menu can be designated as the primary or secondary links menu via the menu settings page.
                          
+Menu administration tabs:
+
                            
+  
                          • On the administer menu page, administrators can "edit" to change the title, description, parent or weight of a menu item. Under the "operations" column, click on "enable/disable" to toggle a menu item on or off. Only menu items which are enabled are displayed in the corresponding menu block. Note that the default menu items generated by the menu module cannot be deleted, only disabled.
                            • 
+  
                          • Use the "add menu" tab to submit a title for a new custom menu. Once submitted, the menu will appear in a list toward the bottom of the administer menu page underneath the main navigation menu. Under the menu name there will be links to edit or delete the menu, and a link to add new items to the menu.
                            • 
+  
                          • Use the "add menu item" tab to create new links in either the navigation or a custom menu (such as a primary/secondary links menu). Select the parent item to place the new link within an existing menu structure. For top level menu items, choose the name of the menu in which the link is to be added.

+ * @defgroup node_access Node access rights
+ * @{
+ * The node access system determines who can do what to which nodes.
+ *
+ * In determining access rights for a node, node_access() first checks
+ * whether the user has the "administer nodes" permission. Such users have
+ * unrestricted access to all nodes. Then the node module's hook_access()
+ * is called, and a TRUE or FALSE return value will grant or deny access.
+ * This allows, for example, the blog module to always grant access to the
+ * blog author, and for the book module to always deny editing access to
+ * PHP pages.
+ *
+ * If node module does not intervene (returns NULL), then the
+ * node_access table is used to determine access. All node access
+ * modules are queried using hook_node_grants() to assemble a list of
+ * "grant IDs" for the user. This list is compared against the table.
+ * If any row contains the node ID in question (or 0, which stands for "all
+ * nodes"), one of the grant IDs returned, and a value of TRUE for the
+ * operation in question, then access is granted. Note that this table is a
+ * list of grants; any matching row is sufficient to grant access to the
+ * node.
+ *
+ * In node listings, the process above is followed except that
+ * hook_access() is not called on each node for performance reasons and for
+ * proper functioning of the pager system. When adding a node listing to your
+ * module, be sure to use db_rewrite_sql() to add
+ * the appropriate clauses to your query for access checks.
+ *
+ * To see how to write a node access module of your own, see

+ * @defgroup search Search interface
+ * @{
+ * The Drupal search interface manages a global search mechanism.
+ *
+ * Modules may plug into this system to provide searches of different types of
+ * data. Most of the system is handled by search.module, so this must be enabled
+ * for all of the search features to work.
+ *
+ * There are three ways to interact with the search system:
+ * - Specifically for searching nodes, you can implement nodeapi('update index')
+ *   and nodeapi('search result'). However, note that the search system already
+ *   indexes all visible output of a node, i.e. everything displayed normally
+ *   by hook_view() and hook_nodeapi('view'). This is usually sufficient.
+ *   You should only use this mechanism if you want additional, non-visible data
+ *   to be indexed.
+ * - Implement hook_search(). This will create a search tab for your module on
+ *   the /search page with a simple keyword search form. You may optionally
+ *   implement hook_search_item() to customize the display of your results.
+ * - Implement hook_update_index(). This allows your module to use Drupal's
+ *   HTML indexing mechanism for searching full text efficiently.
+ *
+ * If your module needs to provide a more complicated search form, then you need
+ * to implement it yourself without hook_search(). In that case, you should
+ * define it as a local task (tab) under the /search page (e.g. /search/mymodule)
+ * so that users can easily find it.

+GNU GENERAL PUBLIC LICENSE
+
+              Version 2, June 1991
+
+Copyright (C) 1989, 1991 Free Software Foundation, Inc. 675 Mass Ave,
+Cambridge, MA 02139, USA. Everyone is permitted to copy and distribute
+verbatim copies of this license document, but changing it is not allowed.
+
+                  Preamble
+
+The licenses for most software are designed to take away your freedom to
+share and change it. By contrast, the GNU General Public License is
+intended to guarantee your freedom to share and change free software--to
+make sure the software is free for all its users. This General Public License
+applies to most of the Free Software Foundation's software and to any other
+program whose authors commit to using it. (Some other Free Software
+Foundation software is covered by the GNU Library General Public License
+instead.) You can apply it to your programs, too.
+
+When we speak of free software, we are referring to freedom, not price. Our
+General Public Licenses are designed to make sure that you have the
+freedom to distribute copies of free software (and charge for this service if
+you wish), that you receive source code or can get it if you want it, that you
+can change the software or use pieces of it in new free programs; and that
+you know you can do these things.
+
+To protect your rights, we need to make restrictions that forbid anyone to
+deny you these rights or to ask you to surrender the rights. These restrictions
+translate to certain responsibilities for you if you distribute copies of the
+software, or if you modify it.
+
+For example, if you distribute copies of such a program, whether gratis or for
+a fee, you must give the recipients all the rights that you have. You must make
+sure that they, too, receive or can get the source code. And you must show
+them these terms so they know their rights.
+
+We protect your rights with two steps: (1) copyright the software, and (2)
+offer you this license which gives you legal permission to copy, distribute
+and/or modify the software.
+
+Also, for each author's protection and ours, we want to make certain that
+everyone understands that there is no warranty for this free software. If the
+software is modified by someone else and passed on, we want its recipients
+to know that what they have is not the original, so that any problems
+introduced by others will not reflect on the original authors' reputations.
+
+Finally, any free program is threatened constantly by software patents. We
+wish to avoid the danger that redistributors of a free program will individually
+obtain patent licenses, in effect making the program proprietary. To prevent
+this, we have made it clear that any patent must be licensed for everyone's
+free use or not licensed at all.
+
+The precise terms and conditions for copying, distribution and modification
+follow.
+
+           GNU GENERAL PUBLIC LICENSE
+ TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND
+               MODIFICATION
+
+0. This License applies to any program or other work which contains a notice
+placed by the copyright holder saying it may be distributed under the terms
+of this General Public License. The "Program", below, refers to any such
+program or work, and a "work based on the Program" means either the
+Program or any derivative work under copyright law: that is to say, a work
+containing the Program or a portion of it, either verbatim or with
+modifications and/or translated into another language. (Hereinafter, translation
+is included without limitation in the term "modification".) Each licensee is
+addressed as "you".
+
+Activities other than copying, distribution and modification are not covered
+by this License; they are outside its scope. The act of running the Program is
+not restricted, and the output from the Program is covered only if its contents
+constitute a work based on the Program (independent of having been made
+by running the Program). Whether that is true depends on what the Program
+does.
+
+1. You may copy and distribute verbatim copies of the Program's source
+code as you receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice and
+disclaimer of warranty; keep intact all the notices that refer to this License
+and to the absence of any warranty; and give any other recipients of the
+Program a copy of this License along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and you
+may at your option offer warranty protection in exchange for a fee.
+
+2. You may modify your copy or copies of the Program or any portion of it,
+thus forming a work based on the Program, and copy and distribute such
+modifications or work under the terms of Section 1 above, provided that you
+also meet all of these conditions:
+
+a) You must cause the modified files to carry prominent notices stating that
+you changed the files and the date of any change.
+
+b) You must cause any work that you distribute or publish, that in whole or in
+part contains or is derived from the Program or any part thereof, to be
+licensed as a whole at no charge to all third parties under the terms of this
+License.
+
+c) If the modified program normally reads commands interactively when run,
+you must cause it, when started running for such interactive use in the most
+ordinary way, to print or display an announcement including an appropriate
+copyright notice and a notice that there is no warranty (or else, saying that
+you provide a warranty) and that users may redistribute the program under
+these conditions, and telling the user how to view a copy of this License.
+(Exception: if the Program itself is interactive but does not normally print such
+an announcement, your work based on the Program is not required to print
+an announcement.)
+
+These requirements apply to the modified work as a whole. If identifiable
+sections of that work are not derived from the Program, and can be
+reasonably considered independent and separate works in themselves, then
+this License, and its terms, do not apply to those sections when you distribute
+them as separate works. But when you distribute the same sections as part
+of a whole which is a work based on the Program, the distribution of the
+whole must be on the terms of this License, whose permissions for other
+licensees extend to the entire whole, and thus to each and every part
+regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest your rights to
+work written entirely by you; rather, the intent is to exercise the right to
+control the distribution of derivative or collective works based on the
+Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of a
+storage or distribution medium does not bring the other work under the scope
+of this License.
+
+3. You may copy and distribute the Program (or a work based on it, under
+Section 2) in object code or executable form under the terms of Sections 1
+and 2 above provided that you also do one of the following:
+
+a) Accompany it with the complete corresponding machine-readable source
+code, which must be distributed under the terms of Sections 1 and 2 above
+on a medium customarily used for software interchange; or,
+
+b) Accompany it with a written offer, valid for at least three years, to give
+any third party, for a charge no more than your cost of physically performing
+source distribution, a complete machine-readable copy of the corresponding
+source code, to be distributed under the terms of Sections 1 and 2 above on
+a medium customarily used for software interchange; or,
+
+c) Accompany it with the information you received as to the offer to distribute
+corresponding source code. (This alternative is allowed only for
+noncommercial distribution and only if you received the program in object
+code or executable form with such an offer, in accord with Subsection b
+above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it. For an executable work, complete source code
+means all the source code for all modules it contains, plus any associated
+interface definition files, plus the scripts used to control compilation and
+installation of the executable. However, as a special exception, the source
+code distributed need not include anything that is normally distributed (in
+either source or binary form) with the major components (compiler, kernel,
+and so on) of the operating system on which the executable runs, unless that
+component itself accompanies the executable.
+
+If distribution of executable or object code is made by offering access to
+copy from a designated place, then offering equivalent access to copy the
+source code from the same place counts as distribution of the source code,
+even though third parties are not compelled to copy the source along with the
+object code.
+
+4. You may not copy, modify, sublicense, or distribute the Program except as
+expressly provided under this License. Any attempt otherwise to copy,
+modify, sublicense or distribute the Program is void, and will automatically
+terminate your rights under this License. However, parties who have received
+copies, or rights, from you under this License will not have their licenses
+terminated so long as such parties remain in full compliance.
+
+5. You are not required to accept this License, since you have not signed it.
+However, nothing else grants you permission to modify or distribute the
+Program or its derivative works. These actions are prohibited by law if you
+do not accept this License. Therefore, by modifying or distributing the
+Program (or any work based on the Program), you indicate your acceptance
+of this License to do so, and all its terms and conditions for copying,
+distributing or modifying the Program or works based on it.
+
+6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the original
+licensor to copy, distribute or modify the Program subject to these terms and
+conditions. You may not impose any further restrictions on the recipients'
+exercise of the rights granted herein. You are not responsible for enforcing
+compliance by third parties to this License.
+
+7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues), conditions
+are imposed on you (whether by court order, agreement or otherwise) that
+contradict the conditions of this License, they do not excuse you from the
+conditions of this License. If you cannot distribute so as to satisfy
+simultaneously your obligations under this License and any other pertinent
+obligations, then as a consequence you may not distribute the Program at all.
+For example, if a patent license would not permit royalty-free redistribution
+of the Program by all those who receive copies directly or indirectly through
+you, then the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under any
+particular circumstance, the balance of the section is intended to apply and
+the section as a whole is intended to apply in other circumstances.
+
+It is not the purpose of this section to induce you to infringe any patents or
+other property right claims or to contest validity of any such claims; this
+section has the sole purpose of protecting the integrity of the free software
+distribution system, which is implemented by public license practices. Many
+people have made generous contributions to the wide range of software
+distributed through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing to
+distribute software through any other system and a licensee cannot impose
+that choice.
+
+This section is intended to make thoroughly clear what is believed to be a
+consequence of the rest of this License.
+
+8. If the distribution and/or use of the Program is restricted in certain
+countries either by patents or by copyrighted interfaces, the original copyright
+holder who places the Program under this License may add an explicit
+geographical distribution limitation excluding those countries, so that
+distribution is permitted only in or among countries not thus excluded. In such
+case, this License incorporates the limitation as if written in the body of this
+License.
+
+9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time. Such new versions will be
+similar in spirit to the present version, but may differ in detail to address new
+problems or concerns.
+
+Each version is given a distinguishing version number. If the Program specifies
+a version number of this License which applies to it and "any later version",
+you have the option of following the terms and conditions either of that
+version or of any later version published by the Free Software Foundation. If
+the Program does not specify a version number of this License, you may
+choose any version ever published by the Free Software Foundation.
+
+10. If you wish to incorporate parts of the Program into other free programs
+whose distribution conditions are different, write to the author to ask for
+permission. For software which is copyrighted by the Free Software
+Foundation, write to the Free Software Foundation; we sometimes make
+exceptions for this. Our decision will be guided by the two goals of
+preserving the free status of all derivatives of our free software and of
+promoting the sharing and reuse of software generally.
+
+               NO WARRANTY
+
+11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE,
+THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT
+PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE
+STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
+OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT
+WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED,
+INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES
+OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND
+PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL
+NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR
+AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR
+ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE
+LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL,

                          One of the more tedious moments in visiting a new website is filling out the registration form. Here at %site, you do not have to fill out a registration form if you are already a member of %help-links. This capability is called distributed authentication, and is unique to Drupal, the software which powers %site.

                          Distributed authentication enables a new user to input a username and password into the login box, and immediately be recognized, even if that user never registered at %site. This works because Drupal knows how to communicate with external registration databases. For example, lets say that new user 'Joe' is already a registered member of Delphi Forums. Drupal informs Joe on registration and login screens that he may login with his Delphi ID instead of registering with %site. Joe likes that idea, and logs in with a username of joe@remote.delphiforums.com and his usual Delphi password. Drupal then contacts the remote.delphiforums.com server behind the scenes (usually using XML-RPC, HTTP POST, or SOAP) and asks: \"Is the password for user Joe correct?\".  If Delphi replies yes, then we create a new %site account for Joe and log him into it.  Joe may keep on logging into %site in the same manner, and he will always be logged into the same account.
