How can I save a multiple select array with the settings API for a plug-in options page?

So, it looks like two things are going on here: echo “<select id=’$id’ style=”width:15em;height:10em;” class=”select$field_class” name=”” . $buddha_option_name . “[$id]” multiple>”; As noted by @Radek, you could have made the name of the select box an array by using [] – e.g. name=”my_option_name[]” – this will result in the filed $_POST[‘my_option_name’] being an array of … Read more

Limit the number of inactive widgets

Tested under v3.2.1: $sidebars = wp_get_sidebars_widgets(); if(count($sidebars[‘wp_inactive_widgets’]) > 10){ $new_inactive = array_slice($sidebars[‘wp_inactive_widgets’],-10,10); // remove the dead widget options $dead_inactive = array_slice($sidebars[‘wp_inactive_widgets’],0,count($sidebars[‘wp_inactive_widgets’])-10); foreach($dead_inactive as $dead){ $pos = strpos($dead,’-‘); $widget_name = substr($dead,0,$pos); $widget_number = substr($dead,$pos+1); $option = get_option(‘widget_’.$widget_name); unset($option[$widget_number]); update_option(‘widget_’.$widget_name,$option); } // save our new widget setup $sidebars[‘wp_inactive_widgets’] = $new_inactive; wp_set_sidebars_widgets($sidebars); } The above code limits the … Read more

dbDelta support for FOREIGN KEY

Do I really have to live with that until dbDelta supports FOREIGN KEY? Quite frankly, yes. But that’s the beauty of open source – anyone is welcome to post a patch!

Mega Menu Walker

If I understand the problem setup correctly, you could try to do the break and widget class counting within the wp_nav_menu_objects filter. Here’s an updated example, it’s rather expanded because of the extra debug part: add_filter( ‘wp_nav_menu_objects’, function( $items, $args ) { // Only apply this for the ‘primary’ menu: if( ‘primary’ !== $args->theme_location ) … Read more

Call to a member function add_rewrite_tag() on null

While I don’t like taking credit for someone else’s answer, I also don’t like leaving a question without answer when the answer does exist and it’s already been given. I hope Milo won’t mind if I copy the answer from his comment. The register_taxonomy calls should be hooked to init.

You can find a list of those files in the Template Hierarchy. Those specific template files can be overridden with new ones, but unless the parent theme … Read more
