On my custom module, I defined the following hook_menu() function.

function motel_events_menu() {

    $items['ajax/pastevents/%'] = array(
        'title' => 'Get Past Events',
        'page callback' => '_motel_events_get_pastevents(%)',
        'access arguments' => array('access content'),
        'type' => MENU_CALLBACK,
    );

    return $items;
}

In this function, how can I retrieve the % argument that is passed in 'ajax/pastevents/%' so I can send it to my _motel_events_get_pastevents() function?

'page callback' => '_motel_events_get_pastevents(%)',

should be

'page callback' => '_motel_events_get_pastevents',

then insert

 'page arguments' => array(2),

immediately after. ajax is at position 0, pastevent is at position 1 and the wildcard % is at position 2. Counting for arguments starts at 0. The callback function will have a variable to pass in the wildcard value argument.

function _motel_events_get_pastevents($arg){

Some folks like to use the arg(n) form for arguments as its always present whether declared or not but I tend to use formal declarations.

  • Thank you very much for your reply, this is exactly what I've done. I didn't say I changed page callback' => '_motel_events_get_pastevents(%) to page callback' => '_motel_events_get_pastevents in my comment though.. Thanks a lot! – acanana Aug 27 '15 at 6:57

You don't need to defined % in page callback you get url parameter within your function by calling arg(2).
