Using Gravity Forms ‘gform_addon_pre_process_feeds’ PHP filter

The gform_addon_pre_process_feeds filter allows you to modify the feed objects before they are processed during form submission in Gravity Forms.


To apply the filter, you can use the following code:

add_filter('gform_addon_pre_process_feeds', 'your_function_name', 10, 3);

Generic, Form-specific: applies to feeds for all add-ons for a specific form.

add_filter( 'gform_addon_pre_process_feeds_{FORM_ID}', 'your_function_name' );

Addon-specific: applies to feeds for a specific add-on for all forms.

add_filter( 'gform_{ADDON_SLUG}_pre_process_feeds', 'your_function_name', 10, 3 );

See the Gravity Forms Add-On Slugs article for a list of possible slugs.

Addon-specific, Form-specific: applies to feeds for a specific add-on and form.

add_filter( 'gform_{ADDON_SLUG}_pre_process_feeds_{FORM_ID}', 'your_function_name' );

  • $entry (Entry Object): Current entry for which $feeds will be processed.
