Fatal error: Uncaught exception 'PDOException' with message 'SQLSTATE[42S22]: Column not found: 1054 Unknown column 'id' in 'where clause''

Answer 1

The error message indicates that the table admin in your database does not have a column called id. You need to check what columns are available in the table, but without more information (such as the table definition), I can't be more help.

Answer 2

this will sort the problem you have , I had a similar issue but i manage to fix it.

{$sql = "DELETE FROM admin where id =".$_GET['id'];}
