register_activation_hook not firing

  • I’m creating a plugin and I have some functionality that I want to fire when it is activated for the first time. I’ve tried a couple different methods to have my code fire on this event.

    1. In an object I define, I tried register_activation_hook(__FILE__, array(&$this, 'funcname')) and having my function funcname() in said object as well. This is inside the core file for my plugin.

    2. I tried moving my functionality out of the object. register_activation_hook(__FILE__, 'funcname') and having my function funcname be outside of my object as well.

    3. I tried bypassing the register_activation_hook function and calling add_action('activate_'.path_to_my_plugin, 'funcname') directly.

    Any idea of what might be causing this, or anyone have anything I should check? I’m copying the functionality straight from the documentation as far as I can see.

    Thanks

    I’m not sure if this will help in narrowing things down, but my main file is snips-tool.php in the snips-tool subdirectory of my plugins folder. Currently I have my action hook written (within a class) in the form:

    add_action('activate_snips-tool/snips-tool.php', array(&$this, 'activate'));

    Other forms tried:
    register_activation_hook(__FILE__, array(&$this, 'activate'));

    Outside of my class:
    register_activation_hook(__FILE__, 'activate');
    add_action('activate_snips-tool/snips-tool.php', 'activate');

    Please, any help would be very much appreciated.

    What is the ‘activate’ function trying to do?

    I encountered the same problem when I wanted the plugin to create tables in the database upon activation. I checked the SQL statements with an echo and they were correct.

    It turned out that I was referencing the global $wpdb value in the method but I did not declare it outside its scope.

    Well I’m trying to use it to issue a redirect with a header('Location: '.$url) call, but I was testing it earlier by using a add_option('test', 5); and seeing if it showed up in the options table.

    I just tried again today and it seems my add_option now works. But my redirect still isn’t firing… does the wp_redirect function allow for redirecting to offsite locations?

    The wp_redirect function does allow for external locations:
