Basically what I am trying to do is have an option of choosing an "expiry time" when inserting a record. I will then use that expiry time to make a countdown clock that will expire the record when reached 0; but that's the step after. Right now I am having a bit of issue inserting that expiry time into the database. Here is my code.
The error i get in the option value is something like <option value="<b>Notice</b>: Undefined variable...">.
<?php
$date_added = date('Y-m-d H:i:s');
$expiry_1 = date('Y-m-d H:i:s', strtotime('$date_added + 1 hour'));
$expiry_6 = date('Y-m-d H:i:s', strtotime('$date_added + 6 hours'));
$expiry_12 = date('Y-m-d H:i:s', strtotime('$date_added + 12 hours'));
?>
<fieldset>
<label>Expiry Time</label>
<select name="expiry_time">
<option value="0">Select Time</option>
<option value="<?php echo $expiry_1; ?>">1 hour</option>
<option value="<?php echo $expiry_6; ?>">6 hours</option>
<option value="<?php echo $expiry_12; ?>">12 hours</option>
</select>
</fieldset>
