Handle error validation in step form

Hi @bhrugesh12

I hope you are doing well.

You can use the forminator_custom_form_submit_errors hook:

$submit_errors = apply_filters( 'forminator_custom_form_submit_errors', $submit_errors, $form_id, $field_data_array );

A small example is found here:

This example verifies if two email fields match and return an error if not. You can customize it to verify the fields you need.

You can use the code as a mu-plugin:

Hope this information helps

Kind regards
