We use a module in our projekt named "certificate". There is one Function in the *.module file which contains this:
function certificate_menu() {
$items['node/%node/certificate'] = array(
'title' => 'Certificate',
'description' => 'Display earned certificate for this node',
'page callback' => 'certificate_node_certificate',
'page arguments' => array(1),
'access callback' => 'certificate_can_access_certificate',
'access arguments' => array(1),
'file' => 'certificate.pages.inc',
'type' => MENU_LOCAL_TASK,
);
}
There is a "certificate_can_access_certificate" callback to check if the User has Access to download a certificate.
Whan I now try is to make a redirect to page "/my/another/access/denied/page/for/certificate" when this callback returns false.
What is now the recommended way to solve this ?
1) Manipulate the callback function and everytime when its returned "False" I just write an exit; there and redirect before with location() ?
2) Is there a way to create a function in my own custom module to make this redirect possible ?
3) Do I have to manipulate the function certificate_menu() in a special way ?
I do not know much about Drupal so I dont know whats the best way to do and how I have to do this ...
You can use "drupal_goto" function within your access callback to redirect.
Here's an example, where if you add ?doredirect=true it will redirect from the access function.
function certificate_menu() {
$items['mytestpage'] = array(
'title' => 'Certificate',
'description' => 'Display earned certificate for this node',
'page callback' => 'certificate_testpage',
'access callback' => 'certificate_access',
);
return $items;
}
function certificate_testpage() {
return 'testing!';
}
function certificate_access() {
if(isset($_GET['doredirect'])) {
drupal_goto('', array(), 301);
}
return 1;
}
Also, please note, you need to return $items within your hook_menu, otherwise your page callback won't register.

What I want is pretty simple. I have registered a path
function spotlight_menu() {
$items = array();
$items['congres'] = array(
'title' => 'Congres',
'title arguments' => array(2),
'page callback' => 'taxonomy_term_page',
'access callback' => TRUE,
'type' => MENU_NORMAL_ITEM,
);
return $items;
}
When this menu item is triggered, I want to redirect (without changing the url) to a taxonomy page, of which the term is chosen in a function that runs when this function is called.
How can I do this (especcially without changing the url) ?
You can't call taxonomy_term_page directly as your page callback as you'd need to provide a load function to load the term, which is just going to be too difficult with the setup you've got.
Instead, define your own page callback as an intermediary and just return the output from taxonomy_term_page directly:
function spotlight_menu() {
$items = array();
$items['congres'] = array(
'title' => 'Congres',
'page callback' => 'spotlight_taxonomy_term_page',
'access callback' => TRUE,
'type' => MENU_NORMAL_ITEM,
);
return $items;
}
function spotlight_taxonomy_term_page() {
// Get your term ID in whatever way you need
$term_id = my_function_to_get_term_id();
// Load the term
$term = taxonomy_term_load($term_id);
// Make sure taxonomy_term_page() is available
module_load_include('inc', 'taxonomy', 'taxonomy.pages');
// Return the page output normally provided at taxonomy/term/ID
return taxonomy_term_page($term);
}
I have a module in which I build a form. I can hit form via a menu item that was also created in that module. When I try to load the form via ajax I get the entire page (header, form and footer) instead of just the form. Here's the menu item:
$items['sendmessage'] = array(
'title' => 'Send Message',
'description' => 'Send a message',
'page callback' => 'drupal_get_form',
'page arguments' => array('rmessages_message_form', 1),
'access callback' => TRUE,
'type' => MENU_NORMAL_ITEM,
);
Here's the javascript:
$('.send_message').click(function(){
$('.send-message-dialog').dialog('open');
$('.send-message-dialog .dialog-content').load('/sendmessage/7');
}
);
If I load the URL via a browser, the form loads. Is there some way to get drupal to just render the form and return the HTML rather than trying to load the entire page.
This seems to be working...gotta remember the drupal_render function ;)
$items['sendmessage'] = array(
'page callback' => 'rmessage_send_message_form',
'page arguments' => array('rmessages_message_form', 1),
'access callback' => TRUE
);
Using drupal_build_form to get an array of items, which gets rendered by drupal_render()
function rmessage_send_message_form($form_id, $nid) {
$form_state = array();
echo drupal_render(drupal_build_form('rmessages_message_form', $form_state, $nid));
}
I think the nicest way to do it would be to have your form accessible from the normal URL (for those without JavaScript) and available to AJAX. You can do that like this:
function rmessage_menu() {
$items['sendmessage/%node'] = array( // Using the '%node' load argument ensures that the nid attempting to be accessed belongs to an existing node.
'title' => 'Send Message',
'description' => 'Send a message',
'page callback' => 'rmessages_message_form',
'page arguments' => array(1),
'access callback' => TRUE
);
return $items;
}
function rmessages_message_form($node) {
$form = drupal_get_form('rmessage_send_message_form', $node->nid);
// Just print the form directly if this is an AJAX request
if (isset($_GET['ajax'])) {
echo render($form);
// Halt page processing
drupal_exit();
}
// Otherwise return the form as normal
return $form;
}
Then in your JS you would just need to add the query string:
$('.send_message').click(function(){
$('.send-message-dialog').dialog('open');
$('.send-message-dialog .dialog-content').load('/sendmessage/7?ajax');
}
);
Hope that helps
based on some condition i want to give access to a module.
if(abc == abc) {
//give access to module xyz.
}
There's no such concept as giving access to a whole module in Drupal, only pages that a module would define. Usually this is done by implementing hook_menu() to define the page(s) and then providing either an access callback or access arguments.
The first defines a function that will be called to make your access decision:
function mymodule_menu() {
$items['some/path'] = array(
'title' => 'Some Title',
'page callback' => 'mymodule_callback',
'access callback' => 'mymodule_some_path_access'
);
return $items;
}
function mymodule_some_path_access() {
global $user;
if ($user->foo == 'bar') {
// Access allowed, return TRUE
return TRUE;
}
// Access not allowed, return FALSE
return FALSE;
}
The second defines arguments that will be passed to the user_access function. This will usually be based on permissions your module provides:
function mymodule_menu() {
$items['some/path'] = array(
'title' => 'Some Title',
'page callback' => 'mymodule_callback',
'access arguments' => array('access mymodule')
);
return $items;
}
function mymodule_perm() {
return array(
'access mymodule'
);
}
In the second example a user will be denied access unless they have the permission 'access mymodule' (as defined in the permissions admin area of Drupal).
Hope that helps
I trying to get the twitter_admin_form and twitter_user_settings form in a div.
/**
* Get twitter form for user
* #param $account
* #type user object
*/
function getTwitterForm($account){
//module_load_include('inc', 'twitter');
module_load_all();
$twitter_form = drupal_get_form('twitter_admin_form');
return $twitter_form;
}
I get a get a drupal error.
warning: call_user_func_array() [function.call-user-func-array]: First argument is expected to be a valid callback, 'twitter_admin_form' was given in .../includes/form.inc on line 372.

I'm not sure what I'm doing wrong. The twitter_admin_form doesn’t have any arguments hence I thought it would be simple to get and display.
I’m new forms/menu so I’m not 100% sure what %user_category, %map and %index are and how to pass them in.
How do you know what the valid forms are?
When you call drupal_get_form you supply a form id, which is the function that Drupal needs to call. The problem you are experiencing is that Drupal cannot find the function: twitter_admin_form.
Either it's located in an include file, and you need to include it, or you have named it something else.
The error you get stems from the line:
$twitter_form = drupal_get_form('twitter_admin_form');
It expects 'twitter_admin_form' to be a valid callback function, but can't find it. This is probably because the related file 'twitter.pages.inc' is not included at the time of your call.
You could fix that via a:
module_load_include('inc', 'twitter', 'twitter.pages');
(Given the commented line in your code sample, you seem to have tried something like this, but forgot to give the name of the file to include).
I have a page that is definitely not a form but I need to use some callback functions to load data from an external source and display (e.g. a list of buildings on campus and their accessibility information).
What I have a need for is a landing listing page (lists all the buildings) and a 'view individual building' page. Also, I have a page where you punch in your student ID and view information on testing procedures. And finally I have a page that is basically a form (which I have done before successfully in the past).
Now, I HAD the building list working, however I made a small change and it stopped working!
Currently my hook_menu() function looks as below:
<?php
/**
* Implementation of hook_menu()
*/
function disability_menu()
{
$items = array();
// Ignore me, shell
$items['quickreg'] = array(
'title' => 'Quick Registration',
'description' => t(''),
'page callback' => 'drupal_get_form',
'page arguments' => array(),
'file' => 'disability.quickreg.view.inc',
'access arguments' => array('access quick registration system'),
'type' => MENU_SUGGESTED_ITEM,
);
$items['tests/status'] = array(
'title' => 'Test Status Results',
'description' => t('Check on the status of your tests'),
'page callback' => 'disability_view_testing_status',
'page arguments' => array(),
'file' => 'disability.tests.view.inc',
'access arguments' => array('access test check information'),
'type' => MENU_CALLBACK,
);
$items['tests'] = array(
'title' => 'Testing Services',
'description' => t('Check on the status of your tests'),
'page callback' => 'disability_view_testing',
'page arguments' => array(),
'file' => 'disability.tests.view.inc',
'access arguments' => array('access test check information'),
'type' => MENU_SUGGESTED_ITEM,
);
$items['access/%building'] = array(
'title' => 'Campus Accessibility Guide',
'description' => t('A summary list of detailed accessibliity information about each building on the A&M campus'),
'page callback' => 'disability_view_access',
'page arguments' => array(1),
'file' => 'disability.access.view.inc',
'access arguments' => array('access building access information'),
'type' => MENU_SUGGESTED_ITEM,
);
return $items;
}
Before some change I must have made the menu item for "Campus Accessibility Guide" would show up properly (after being enabled of course). The /access url would work correctly displaying a list of all building and the /access/12345 would correctly display the single record of ID# 12345.
Now the access/%building menu entry is not even showing up and even sending the url /access into a redirect loop (making me think it's passing in something for the ID which sends it into the view specific function that redirects to /access when the ID doesn't exist).
Can anyone tell me what I'm doing wrong or what I need to do to support 2 themed pages: a /access and /access/%building url pattern?
You should only use %name instead of % in urls when you have a function that you want to act on the url. Drupal does this all over the place with user and node, and this is very smart, as you only one place need to have the code to load an user or a node, but it get used in a lot of places. In this case I bet it's a bit overkill to make a function to load the building. On the other hand the advantage is that doing it that way, you get the 404 handling, if no object can be found. The best solution really comes down to how you want to handle buildings that does not exist. You could even make your 'Campus Accessibility Guide' function handle the 404 which would make the two options more or less equal. I would go for whatever is easiest for you to make.
