# Validate Structure validate_guid

 * In the Validate Structure section we see that all our documents are coming back
   with the “The guid does not contain the site URL” warning.
 * Within wp-document-revisions/includes/class-wp-document-revisions-validate-structure.
   php there is a `validate_guid` function which is expecting the guid to be in 
   a format like this –
 *     ```wp-block-code
       ?post_type=document&p=
       ```
   
 * But looking at an example, they appear to be stored with the ampersand converted
   to its HTML entity –
 *     ```wp-block-code
       ?post_type=document&p=
       ```
   
 * Not sure if WordPress just changed how that gets stored or what but, updating
   that function removes most all the errors:
 * There are a few references to this in that `validate_guid` function, but we don’t
   fit into the other cases so we only needed to modify one reference.
 * Changed –
 *     ```wp-block-code
       $permalink1 = site_url( '?post_type=document&p=' . (string) $doc_id );
       ```
   
 * To –
 *     ```wp-block-code
       $permalink1 = site_url( '?post_type=document&p=' . (string) $doc_id );
       ```
   
 * Seems like you might want to account for both but looking at even ones uploaded
   recently, the guid is using `&` and not `&` so probably just WordPress changed
   how they store that at some point?
 * You could probably support both just by running the guid through the `html_entity_decode`
   function, which converts entities back to their original character(s).
 * Thanks!
