Changes are made at your own risk and are not guaranteed to work. Always make backups of the database and files prior to implementing hacks. Make a special backup of the file and/or template you are modifying so that you can roll back quickly.
Hacks are dangerous and can cause your site to stop working. They make later updates to ExpressionEngine more difficult; you should track your hacks for post-update re-implementation.
Most hacks are unnecessary, please review the Development Documentation for information on expanding ExpressionEngine via Modules, Extensions, and Plugins.
Hacks are never officially supported.
Question:
In the public memberlist, how can I add an option to sort by last visit?
Answer:
Modify the file called mod.member_memberlist.php:
Around line 919, add the following code:
//------------------------------------
// Add sort by last visit date
//------------------------------------
$selected = ($order_by == 'last_visit') ? " selected='selected' " : '';
$menu .= "<option value='last_visit'".$selected.">".$LANG->line('last_visit')."</option>\n";
//-------------------------------------
// End added code
//-------------------------------------
