PHP MYSQL更新多个字段，包括DATETIME字段

Question

I can update the field 'delivered' from 0 to 1 no problem but when I try to update 'delivered_time' nothing happens in the database. This may be to do with the way I am writing the code but If anybody could help I would really appreciate it, thanks!

if (isset($_POST['delivered']) === false) {
                mysql_query("UPDATE `listings` SET `delivered_time` = '{$date->format('Y-m-d H:i:s')}' AND `delivered` = 1 WHERE `order_id` = $order_id");
}

I have also tried this but this did not work either

if (isset($_POST['delivered']) === false) {
                    mysql_query("UPDATE `listings` SET `delivered_time` = NOW() AND `delivered` = 1 WHERE `order_id` = $order_id");
} 

My MYSQL database is set to have 'delivered' defined to 0 and is stored as an INT value. The 'delivered_time' field is stored as a DATETIME value in the database.

Try this code

<?php

if (isset($_POST['delivered']) === false) {
    mysql_query("UPDATE `listings` SET `delivered_time` = NOW(),`delivered` = 1 WHERE `order_id` = ".$order_id);
}
?>
