# Meta Key’s

 * Hi Guys, first off, AWESOME PLUGIN! We just started using it to help with custom
   filtering and it has been great. We do have a question however. We have created
   multiple Taxomy and now would like to start adding terms in a batch process to
   our thousands of products. We use a 3rd party plugin called PW Bulk Edit – which
   allows us to add terms (ex.in the case of a taxonomy) in a batch process using
   a single click.
   Unfortunately the custom Taxonomy we added do not display by 
   default in the PW Bulk Editor plugin. We need to add these via adding custom 
   code into our functions.php file. The instructions from the PW Bulk Edit Plugin
   author is listed here: [https://www.pimwick.com/pw-faq/custom-fields/](https://www.pimwick.com/pw-faq/custom-fields/)
   Basically what we require is the Meta Key for each of our custom taxonomies. 
   Is the meta key the Taxonomy Key (see image below). Any help is greatly appreciated!

 * Hi there,
 * Thanks for reaching out, and glad to hear you’ve been enjoying the plugin.
 * In this case, the value you’re looking for would not be a separate ACF-generated
   meta key.
 * For Custom Taxonomies created in ACF, the identifier is the **Taxonomy Key (slug)**
   that you configured when creating the taxonomy. That is the value WordPress uses
   to register and reference the taxonomy.
 * For example, if your taxonomy is configured as:
 *     ```wp-block-code
       Taxonomy Key: product_brand
       ```
   
 * then `product_brand` is the identifier you would typically use when integrating
   with third-party tools.
 * That said, PW Bulk Edit’s example appears to target **custom fields stored as
   post meta**, whereas taxonomies are handled differently in WordPress. You may
   want to confirm with PW Bulk Edit whether their custom column registration supports**
   taxonomies** specifically, rather than only post meta fields.
 * Hope this helps!

 * You guys are the BEST!! Thank you so much! Based on your reply, we were able 
   to get this figured out and custom taxonomies implemented into the PW Bulk Edit
   plugin. We are now able to do batch editing for these. THANK YOU!! You can mark
   this as closed.
