are you sure that id is a column in the myaduan table?

is it upper cased? ID?

is it rowID?

Also, I would encourage you to sanitize your data before inserting it into your database.

<?php include'e.php';
    if(!isset($_POST['submit'])) //this is confusing
    {
        $id = mysql_real_escape_string($_GET[id]); //since the data you seem to care about is a GET....
        $q="SELECT * FROM myaduan WHERE id=" . $id;
        $result=mysql_query($q);
        $myaduan=mysql_fetch_array($result);
    }
?>

also, you may want to consider migrating from this proceedural, and now outdated, method and instead look into mysqli which is very similar in syntax but has future support for PHP.

hi

i think you have missed '=' in line 21

 $u="UPDATE myaduan SET nama_pengadu='$_POST[inputName]', aduan_details'$_POST[inputDec]' WHERE ID=$_POST[id]";

replace the above code as below

$u="UPDATE myaduan SET nama_pengadu='$_POST[inputName]', aduan_details='$_POST[inputDec]' WHERE ID=$_POST[id]";
