Name field validation

Hi @vinodbilagi416

I hope you are doing good today.

Could you be more clear about what is your main goal? Name filed allows using numbers and special characters.

Kind Regards,
Kris

Hello Kris,
Thank you for your quick response, I need to provide the users to enter their names only in the alphabet[a-z, A-Z], it will not accept the numbers[0-9].

Thank you,

Hello @vinodbilagi416

As this isn’t possible out of the box, I forwarded it to our developers in case there’s any filter/workaround that we can share with you here. Your patience is highly appreciated! ??

Thank you,
Dimitris

Hello @vinodbilagi416

Please use the following code in a MU plugin which should do the trick for you.
How to: https://wpmudev.com/docs/using-wordpress/installing-wordpress-plugins/#installing-mu-plugins

<?php
add_filter(
	'forminator_custom_form_submit_errors',
	function( $submit_errors, $form_id, $field_data_array ) {
		$field_name = 'name-1';
		$submitted_fields = wp_list_pluck( $field_data_array, 'value', 'name' );

		if( !preg_match( '/^[a-z]+$/i', $submitted_fields[ $field_name ] ) ) {
			$submit_errors[][ $field_name ] = __( 'There is something wrong ' );
		}

		return $submit_errors;
	},
	10, 
	3
);

Keep in mind to change the name field ID, if not the same with your form, here:
$field_name = 'name-1';

Take care,
Dimitris
