Sending an email notification when the status changes? - php

Question

How can I make it so that when a job status gets changed to "Cancelled" it sends an email to me notifying me of the change after submitting?
<form action='phplib/job_update.php' method='post' id='new_job'>
<label for='status'>Job Status</label>
<select name='status' id='status'>
<?php
$sql = "SELECT * FROM status";
$result = mysqli_query($dbc3, $sql);
while($row = mysqli_fetch_assoc($result)){
echo "<option value='" . $row['id'] . "'";
if($row['id'] == $data['status']) echo "selected='selected'";
echo ">" . ucwords($row['name']) . "</option>";
}
?>
</select>
</form>
What the form looks like:

There are many ways to send email with PHP, but I'll show you the simplest (assuming you're not using any libraries or frameworks). Modify the phplib/job_update.php script. After writing to the database (look for another mysqli_query(...) line) add the following code:
$cancelledCode = // Easiest way to find this is to view source in the HTML
if ($cancelledCode == $_POST['status']) {
$to = 'you#example.com';
$subject = 'Cancelled Job';
$message = 'Yo, a job has been cancelled. ...';
if (!mail($to, $subject, $message)) {
// Error sending mail
}
}
