Post Bulk Update

1 comment

1. 1) Create a new page and assign a new page template to it, lets say site.com/update and update.php. Inside of update.php write you bulk mechanism:

   <?php
   // grab all your posts
   $parts = get_posts(array('post_type' => 'parts', 'numberposts' => -1,))
   
   // loop through every part
   foreach ( $parts as $part ) {
       // get part number
       $partno = get_post_meta( $part->ID, 'parto', true );
   
       $updated_post = array();
       $updated_post['ID'] = $part->ID;
       $updated_post['post_name'] = $partno;
       wp_update_post( $updated_post ); // update existing posts
   
   }
   ?>
   

   You could place this anywhere in your theme but I like to create a page for that so I can easily run a cron job with it.

   Next the function to change the slug of every newly created post:

   <?php
   function change_default_slug($id) {
       // get part number
       $partno = get_post_meta( $id, 'parto', true );
       $post_to_update = get_post( $id );
   
       // prevent empty slug, running at every post_type and infinite loop
       if ( $partno == '' || $post_to_update['post_type'] != 'parts'
         || $post_to_update['post_name'] == $partno )
           return;
   
       $updated_post = array();
       $updated_post['ID'] = $id;
       $updated_post['post_name'] = $partno;
       wp_update_post( $updated_post ); // update newly created post
   }
   
   add_action('save_post', 'change_default_slug');
   ?>
   

   The code above runs every time a post gets saved (e.g. when published for the first time) and sets a new post_name to the part no.
