CRUD Plugin for Wordpress

It's not an interface, but just pointing out here that no plugin is needed to make generic CRUDs within WordPress. The system uses a global class called $ wpdb that already brings an open connection to the bank, so just use it as you would use an instance of PDO, for example.

Codex example:

<?php
    global $wpdb;

    $wpdb->query( 
        $wpdb->prepare( 
            "DELETE FROM $wpdb->postmeta
             WHERE post_id = %d
             AND meta_key = %s
            ",
            13, 'gargle' 
            )
    );

In the same way that you can run queries against the standard WP tables (as in the example) you can run against any other table that is in the same database.

I know at least three:

• link
• link
• link

I recommend seeing the features if they suit your case (which you could have detailed a little better maybe). I like wpDataTables more
