How to call custom edit form
Problem:
$dg->enable_edit('FORM','CRUD','custom.php');
But it is calling your default form. Kindly advise.
Solution:
In enable_edit() function, the 3rd parameter only specifies a custom edit script name, not the actual form.
If you only wanted to modify form layout, check out https://phpgrid.com/example/customize-edit-form-layout/
If you must have your own form, see the demo on custom edit via iframe. Visit https://demo.phpcontrols.com/, and look for "Custom Edit In Iframe".
