API page: http://api.drupal.org/api/drupal/modules!system!system.api.php/function/hook_menu_alter/7
in my module i need to process permission to add content of type "company"
in process function i want to check user vars and return true or redirect in callback
for it i write
<?php
/**
* Implements hook_menu_alter().
*/
function ioncode_menu_alter(&$items) {
$items['node/add/company/']['access callback']='ioncode_companyadd_access';
}
?>and callback
<?php
function ioncode_companyadd_access($op, $type, $account = NULL) {
// original access
$args = func_get_args();
$original_access = call_user_func_array('node_access', $args);
if (!$original_access) {
return false;
}
// some bug !!!
if (arg(2)!='company'){
return $original_access;
}
global $user;
$view = views_get_view('member');
$view->set_display('page_1');
$view->set_arguments(array($user->uid));
$view->pre_execute();
$view->execute();
var_dump(array(arg(2), $args, $original_access, $view->result));
// user's company exists
//var_dump($view->result);
if (empty($view->result)){
return true;
}
else {
drupal_goto('node/1055');
}
}
?>here i use
<?php
// some bug !!!
if (arg(2)!='company'){
return $original_access;
}
?>because requests to url
- "/node/add"
- "/node/add/blablabla"
- "/node/add/anotherexistingtype"
- "/node/add/andsoon"
evaluates by controller my callback function "ioncode_companyadd_access"
why? i think this callback MUST be evaluated only in such paths as
- "/node/add/company"
- "/node/add/companyblablabla"
is it bug or my mistake ?
