limit submission = 1 but 2 persons still be able to submit the form

Hi @youdsan

Hope you are doing fine

To limit the user submission, you can use the following code snippet. It restricts the submissions to 1 per IP address, for the next 24 hours. In case you need a longer time, change the line where the “$future_time” is defined (+1 is one day), also change the 361 to the id of your form.

add_filter( 'forminator_custom_form_submit_errors', function( $submit_errors, $form_id, $field_data_array ) {
	// Add your form IDs here.
	$form_ids = array( 361 );	 
	// Change this to the message that you want to show.
	$message = 'You cannot submit more than 1 time within 24 hours.';
	if ( in_array( intval( $form_id ), $form_ids, true ) ) {
		$user_ip = Forminator_Geo::get_user_ip();
		if ( ! empty( $user_ip ) ) {
			$last_entry = Forminator_Form_Entry_Model::get_last_entry_by_ip_and_form( $form_id, $user_ip );
			if ( ! empty( $last_entry ) ) {
				$entry        = Forminator_API::get_entry( $form_id, $last_entry );
				$current_time = strtotime( date( 'Y-m-d H:i:s' ) );
				$future_time  = strtotime( '+1 day', strtotime( $entry->date_created_sql ) );
				if ( $current_time < $future_time ) {
					$submit_errors[]['submit'] = $message;
				}
			}
		}
	}
	return $submit_errors;
},15,3);


add_filter( 'forminator_custom_form_invalid_form_message', 'wpmudev_invalid_form_error', 10, 2 );
function wpmudev_invalid_form_error( $invalid_form_message, $form_id ){
	if( $form_id != 361 ) {
		return $invalid_form_message;
	}
	$user_ip = Forminator_Geo::get_user_ip();
	if ( ! empty( $user_ip ) ) {
		$last_entry = Forminator_Form_Entry_Model::get_last_entry_by_ip_and_form( $form_id, $user_ip );
		if ( ! empty( $last_entry ) ) {
			$entry        = Forminator_API::get_entry( $form_id, $last_entry );
			$current_time = strtotime( date( 'Y-m-d H:i:s' ) );
			$future_time  = strtotime( '+1 day', strtotime( $entry->date_created_sql ) );
			if ( $current_time < $future_time ) {
				$invalid_form_message = __( 'You cannot submit more than 1 time within 24 hours.', 'forminator' );
			}
		}
	}
	return $invalid_form_message;
}

You can add the above snippet as a mu-plugin on your site:

Hope this information is helpful.
