Custom Validation on Submit

I have looked at the forminator_custom_form_submit_before_set_fields action, and if I could cancel the submit at this point if the membership number is invalid, that would be great. Thank you

Hi @stripytiger

I hope you are doing good today.

I pinged our Formiantor Team to review your query. We will post an update here as soon as more information is available.

Kind Regards,

Hello @stripytiger ,

I’m sorry for the delay on our end. Our developer suggested using forminator_custom_form_submit_errors. With it, you can check submitted fields there and return a custom error message if fields data are not valid.

Let us know if that helps.

kind regards,

Hi. Many thanks for this. I have tried it but it does not work as required – it may be me doing something wrong.

I have added an action in my plugin class like this

add_filter("forminator_custom_form_submit_errors", array($this,"ForminatorPreSubmit"),10,3);

Then I have this.

 function ForminatorPreSubmit($submit_errors, $form_id, $field_data_array)
    {
        /** Do form_id check and any validation code here **/

        $submit_errors[] = "Stripy Tiger has detected an error";                    
        return $submit_errors;
    }

This does stop the form submission, but the error displayed is

Error: Your form is not valid, please fix the errors!

And the form is then locked – so no changes can be made.

Many thanks for helping me.

Hi @stripytiger,

You can try something like this:

add_action( 'forminator_custom_form_submit_errors', function( $submit_errors, $form_id, $field_data_array ){
	
		$submit_errors[]['custom_error'] = __('A new custom error.');
	
	return $submit_errors;
}, 10, 3 );

You can also check the following snippet as an example too:
