Summary

Gravity Form Open AI doesn't store the generated value till the end of the entry creation. This results in generated value being inaccessible until the entry has completely processing.

The new action hook enables the user to customize behavior and tap the generated value and customize as per their use case.

For instance, the case of the user using the generated value to reload back onto the form with the GP Reload Form can do the following:

// Replace 342 with the form id, and 3 with the targetted field id.
add_action( 'gf_openai_post_save_result_to_field_342', 'gw_openai_post_save_result' ); 
function gw_openai_post_save_result( $result ) {
	$_POST['input_3'] = $result;
}
