It is necessary to update the line in the database, the sql query is working on the line, but not on the site.
<?php session_start(); require_once('bd.php'); $taskid = 181; $taskname = "aaa"; $tasktext = "bbb"; $result = mysqli_query($con, "UPDATE `oc_product_description` SET name='$taskname', description='$tasktext' WHERE product_id=$taskid"); ?>
