Function to move the tab of a specific element set to the top of the items form tab list.

<?php
/**
 * Prepends the item form tabs with a specific element set.
 *
 * @param array The item form tabs. These will get filtered.
 * @return array A modified array of item form tabs.

    // The name of our element set. What the link in the tab says.
    $myTabName = 'Example Element Set';
    
    /**
     * We'll create a new array with our element set name and existing content
     * to prepend to our $tabs array later.
     */
    $myTab = array($myTabName => $tabs[$myTabName]);
    
    // Remove our element set's existing tab.
    unset($tabs[$myTabName]);
    
    // Sets the tabs array to our new tab array plus the existing tab array.
    $tabs = $myTab + $tabs;
    
    // Return those sweet tabs.
    return $tabs

/**

add_filter('admin_items_form_tabs', 'custom_item_form_tab_order');

Hi,

I'm trying to add this to my Omeka instance, but just can't figure out where to put the
add_filter('admin_items_form_tabs', 'custom_item_form_tab_order');
line.

Any help would be appreciated.

PS using Omeka 2.3.1
