这个sql有什么问题吗？

Question

I'm trying to insert values into my notifications table. In the PHP file, everything works perfectly fine except when I check my database in PHPmyAdmin, the values are not inserted and they are not there. Can someone please tell me if there's anything wrong with this?

mysqli_query($db_conx, "INSERT INTO notifications(username, initiator, app, note, date_time) 
                 VALUES('$user','anonymous','$app','$note',now())");

Answer 1

By seeing this much code two suggestion for you:-

1. add error reporting code on top of your page just after <?php . Add these lines:-

   error_reporting(E_ALL); ini_set('display_errors',1);

2. Change your query like below:-

   mysqli_query($db_conx, "INSERT INTO notifications(username, initiator, app, note, date_time) VALUES('".$user."','anonymous','".$app."','".$note."','".now()."')") or die(mysqli_error($db_conx));

Note:- This will provide you details about what exact error occur in your code.Thanks.
