Restrict Submissions

Hi @ilan76,

Could you please try this snippet and see how it goes?

<?php

add_filter( 'forminator_custom_form_submit_errors', function( $submit_errors, $form_id, $field_data_array ) {
    // Add your form IDs here.
    $form_ids = array( 6 );
    // Change this to the message that you want to show.
    $message = 'You cannot submit more than 10 times within a day.';
    if ( in_array( intval( $form_id ), $form_ids, true ) ) {
        $last_entry = wpmudev_get_last_few_entries( $form_id );
        if ( $last_entry ) {
            $submit_errors[]['submit'] = $message;
            $GLOBALS['form_error'] = true;
        } else {
            $GLOBALS['form_error'] = false;
        }
    }
    return $submit_errors;
},15,3);

function wpmudev_get_last_few_entries( $form_id ){
    global $wpdb;
    $entry_table_name   = Forminator_Database_Tables::get_table_name( Forminator_Database_Tables::FORM_ENTRY );
    $start_date         = date( 'Y-m-d' ) . ' 00:00:00';
    $end_date           = date( 'Y-m-d' ) . ' 23:59:59';
    $sql                = "SELECT count(*) FROM {$entry_table_name} WHERE form_id = %d AND date_created >= '%s' AND date_created <= '%s'";
    $entry_count        = $wpdb->get_var( $wpdb->prepare( $sql, $form_id, $start_date, $end_date ) ); // phpcs:ignore WordPress.DB.PreparedSQL.NotPrepared
    if ( $entry_count >= 10 ) {
        return true;
    }
    return false;
}

add_filter( 'forminator_custom_form_invalid_form_message', 'wpmudev_invalid_form_error_response_submit', 10, 2 );
function wpmudev_invalid_form_error_response_submit( $invalid_form_message, $form_id ){
	if ( $form_id != 6 ) {
		return $invalid_form_message;
	}

	if ( $GLOBALS['form_error'] ) {
		$invalid_form_message = __( 'You cannot submit more than 10 times within a day.', 'forminator' );
	}

	return $invalid_form_message;
}

You’ll have to change the line in the above code where you notice 6 to your Form ID.

You can apply the above code as a mu-plugins. Please check this link on how to implement the above code as a mu-plugins:
https://wpmudev.com/docs/using-wordpress/installing-wordpress-plugins/#installing-mu-plugins

Please do let us know how that goes.

Kind Regards,

Nithin

Hi @ilan76

We do have plans to add such/similar additional limit options to the plugin. I don’t have ETA but it’s on a list so should be implemented in future.

Best regards,
Adam
