Problem: I have set up a custom form where my site users can select multiple posts. When the form is submitted, the page URL is updated to include those selected post IDs in a repeating URL parameter post_ids. I have custom code in place that triggers a cred_save_data hook when this page loads, and the code grabs post_ids from the URL parameter to update those posts. Multiple post IDs are added to the URL successfully, but only one post is actually updated by the cred_save_data hook.

Solution: To access URL parameters in a cred_save_data hook, find them in $_GET instead of $_POST:

$url_params = $_GET['post_ids'];

Also be sure to use the square bracket notation to indicate multiple values are included:

https://yoursite.com/delegate-update-results/?post_ids[]=44175&post_ids[]=44163&post_ids[]=44162

Then you must update your code to work with an array of values instead of a comma-separated string.
