The menu system in Drupal is known to most people as "that thing in the cache I have to constantly clear to find my links!" That is true. Also, it's a vastly powerful framework for, not just managing your URLs, but adding context and power around the URLs themselves.
Load functions
The following menu item receives a single argument to the URL, an ID for some data -
<?php
$item['my-module/%my_module_data'] = array(
'title' => 'My path',
'page callback' => 'my_module_path',
'page arguments' => array(1),
);
?>When this URL is received, Drupal appends '_load' to the argument's name to call its load function -
<?php
function my_module_data_load($my_data) {
// lookup $my_data index
return $my_data_object;
}
?>Now, your page callback will receive the full, loaded object, rather than just the ID from the URL -
<?php
function my_module_path($my_data_object) {
// object available, passed through load
// load function my_modula_data_load
}
?>
