I would like to limit custom field validation code in a shared library (say functions.php) to only work on specific forms.


Using logic on the [ if($posted_field->id == n)  ] value means I have to manually ensure that forms which the validation does not apply to do not contain those field values. With a number of validations * fields * forms its becoming a significant PITA to manage.


Is there any way to get ones hands on the during the frm_validate_field_entry event ?


Be great to have access to similar logic we have in postprocessing like frm_after_create_entry with [ if ( $args['form']->id == 2 ) ]


ps frm_validate_field_entry $args['id'] is , not

It's in the PHP $_POST associative array. It should be $_POST['form_id']. If for some reason that doesn't work for you, use the Kint debugger to examine the $_POST content.

Many thanks, works perfectly! Wasn't aware that $_POST was available during frm_validate_field_entry, assumed formidable was preprocessing before the PHP global triggers.  

$valid_form_ids = array(2,5);
if (! in_array($_POST['form_id'], $valid_form_ids)) {return;}
