Changing admin columns belongs to a plugin, not to a theme file, because themes should never change anything else than frontend output. You can get the complete plugin here: Plugin Product Editor Column. Looking at the docs you linked to, I see the plugin author requires a child class that mixes multiple separate tasks. That’s … Read more
You can combine add_action() and an is_admin() check: ! is_admin() and add_action( ‘init’, ‘my_custom_callback’ ); Now the callback function will run on front-end only.
There is a plugin called Search everything, where you can break down what you want to search. It does custom fields, posts and of course titles.
I’ve often thought this would make a good feature, though I’ve never seen a plugin for it. I think the term “comment” is probably throwing off your search. I wouldn’t think that this would be stored as a comment internally, but rather as metadata for the post. I did a search for plugins using the … Read more
There is a filter at the end of the function: ‘get_sample_permalink_html’. Hook into this and just replace the shortened form with the full length. <?php # -*- coding: utf-8 -*- /* Plugin Name: T5 Unabridge Permalink Slug */ add_filter( ‘get_sample_permalink_html’, ‘t5_unabridge_sample_permalink’, 10, 2 ); /** * Replaces the shortened permalink with its full form. * … Read more

The validation method … Read more

You can inject something else to fill the gap. In this example, only one user is able to add/delete widgets. function wpse_53398_script_printer(){ // used to display the … Read more
I found this: Exclude Users from Members directory on a BuddyPress based social network We will need to hook to ‘bp_ajax_querystring’ filter. The following code will allow to exclude the users from the members directory.

I just run in the same error when adding extra columns to the default post types. The offending line was the $pagenow check. Quick Edit uses admin-ajax.php so it doesn’t renders the custom columns when it’s done. This doesn’t work: if( ‘edit.php’ == $pagenow && is_admin() ) { add_action( ‘admin_init’, array( $this, ‘init_id_column’ ), 999 … Read more
