WordPress Variable Monitoring Script

I ran into an issue with WP E-commerce recently where the shipping options appeared to be unchecked every day that we went to go and look at them. Turns out it was a line in one of the shipping files that reset the shipping array to just “shipwire” which made it appear as if someone was turning off shipping every day (or a cron job, in this case).

Read about it here: https://wordpress.org/support/topic/upgrade-to-43-and-problems-with-shipping-calculator

Anyways, I created a script to monitor changes to custom_shipping_options and thereby found out what the issue was. Here’s the code, hope it helps.

<script>

Notification.requestPermission();

function notifyMe() {

    if (!( "Notification" in window) ) {
        alert("This browser does not support desktop notification");
    } else if ( Notification.permission === "granted" ) {
        var notification = new Notification("The variable you have been monitoring has changed!");
    } else if ( Notification.permission !== 'denied' ) {
        Notification.requestPermission(function ( permission ) {
            if (permission === "granted") {
                var notification = new Notification("The variable you have been monitoring has changed!");
            }
        });
    }

}
</script>

<?php

# Script creator: Coding Concepts / brendan@carr.ca / codingconcepts.net
# This script is designed to check a variable in the WordPress Options table and notify you of changes.

# Variables

$var = "custom_shipping_options";
$check1 = "fixedrate";
$check2 = "tablerate";
$email = "brendan@carr.ca";
date_default_timezone_set( 'America/Vancouver' );
$refresh_seconds = "10";

# WordPress Stuff

require( "wp-load.php" );
$test = get_option( $var );

# Debug Stuff
# print_r($test);

echo $test[0] . " - " . $test[1]."<BR>";
echo date( "F j, Y, g:i a" );

# If you require a single check: if ($test[0] != $check1) {

    if ( $test[0] != $check1 && $test[1] != $check2 ) {

?>

<script>
    notifyMe();
</script>

<?php
        wp_mail( $email, 'Variable Changed', 'The variable you have been monitoring has changed as of '.date("F j, Y, g:i a") );

    } else {
        echo '<meta http-equiv="refresh" content="'.$refresh_seconds.'">';
    }
?>
