How to update data when the expiration time ends - php

Question

I have build an apps with Codeigniter and want to make cron job and use MySQL
i have a table 'order' and have field like this
order_id | order_expired_date
001 | 2018-11-12 10:03:33
and i have table 'order_payment' like this,
order_id | op_status
001 | pending
I have many fields in these two tables but only include those that have something to do with this question
i have code from php but not in model codeigniter
$result = mysql_query('UPDATE `'order_payment'`
SET op_status='expired'
WHERE
(UNIX_TIMESTAMP( now( ) ) - `order_expired_date`));
The question is how to change the status in the order_payment table to expire when the expiration time is up?

Answer 1

You may use following code, you need to modify code as per your requirements..
<?php
$servername = "xyz";
$username = "xyz";
$password = "xyz";
$dbname = "xyz";
$conn = new mysqli($servername, $username, $password, $dbname);
if ($conn->connect_error) die("Connection failed: " . $conn->connect_error);
$sql = "SELECT *,o.`order_id` as `oid` FROM `order` as o,`order_payment` as op WHERE o.`order_id`=op.`order_id` AND op.`op_status`='paid'";
$result = $conn->query($sql);
if ($result->num_rows > 0) {
while($row = $result->fetch_assoc()) {
$today = date('Y-m-d');
$expDt = date('Y-m-d',strtotime($row['order_expired_date']));
if($today==$expDt){
$updCltSql = "UPDATE `order_payment` SET `op_status`='expired' WHERE `order_id`='".$row['oid']."'";
$conn->query($updCltSql);
}
}
}
$conn->close();
?>
We always prefer core-php file as cron-job..

After plenty of research, this is what I came up with - hope it helps. In your example, I don't think you need to put single quotes around the table name order_payment, unless that is something unique to CodeIgniter.
$orderID = mysql_query("SELECT order_id FROM order"); // Get order IDs of order table, assuming it has the same list of order IDs as the order_payment table
$order_ids = array(); // Put in array
while ($row = mysql_fetch_array($orderID)) {
$order_ids[] = $row['order_id'];
}
foreach ($order_ids as $order_id) { // Iterating through order_id's of array in order to read same index/row number from both tables
$expirationDate = mysql_query("SELECT order_expired_date FROM order WHERE order_id='$order_id'");
$expire = date('M j Y g:i A', $expirationDate); // Converting MySQL timestamp to correct format for strtotime
$today = strtotime("now");
if($today >= $expire) // If past the expiration date
mysql_query("UPDATE order_payment SET op_status='expired' WHERE order_id='$order_id'");
}
