WordPress Development Stack Exchange is a question and answer site for WordPress developers and administrators. It's 100% free, no registration required.

I have been attempting to disable the ability to collapse admin meta boxes. By the looks of it WordPress creates this functionality in postbox.js /wp-admin/js/ but I have been unable to find a hook or suitable JavaScript to overwrite the built in functions.

This is a some test code I am working with:

jQuery('.postbox h3, .postbox .handlediv, .hndle').bind('click', function(e) {

    e.preventDefault();
    return false;

});

Any thoughts on how this could be achieved?

Add this to your functions file and it will kill the metabox toggles:

function kill_postbox(){
    global $wp_scripts;
    $footer_scripts = $wp_scripts->in_footer;
    foreach($footer_scripts as $key => $script){
        if('postbox' === $script)
            unset($wp_scripts->in_footer[$key]);
    }
}
add_action('admin_footer', 'kill_postbox', 1);

Thanks Brian. That seems to the trick nicely. Do you know if removing the entire 'postbox' script in this way causes other issues? –  Scott Oct 25 '11 at 9:12
    
It does affect user column preferences and the sortable metaboxes. You could clone postbox-dev.js and remove the toggle features, place it in your theme js folder and enqueue your hacked version with a dependency on 'jquery-ui-sortable'. This would preserve those other functions. –  Brian Fegter Oct 25 '11 at 9:23
    
Thanks Brian. Luckily I do not need the sorting either so this is a silver bullet! –  Scott Oct 25 '11 at 10:36

Doesn't seem to work (any more), postbox is removed from the in_footer array, but is loaded nonetheless. Found a working solution here, which neatly unbinds the click-handler, and leaves all other postbox functionality in place. –  ptriek Nov 13 '13 at 12:59
