Updating DB Tables Using PHP Dont Work - php

Question

i've made a website, and i made a control panel for it for admin
now iwant to make admin able to add more users to be admins from the control panel
its worked
but i want to make him able to edit them also ( like the usernames and passwords )
i wrote the code but it didnt work and i think the problem maybe with the $editget = $_GET['euid']; it dosent give the number in the url that should be www.example.com/admin/index.php?adpa=users&euid=4 , so it should get me the number 4
i did the same thing with delectation it works and the GET gave me the number after deluid=
so where im going wrong
here is the code :
$eusername = $_POST['eusername'];
$epassword = $_POST['epassword'];
#===========================================================#
if (isset($_POST['edit']) and $_POST['edit'] == 'user') {
$editget = $_GET['euid'];
$edituserinfo = $db->query("update user set username='$eusername', password='$epassword' where user_id='$editget'");
if (isset($edituserinfo)) {
die ("
<center>
<div class='head'>تــــــــم</div>
<div class='bodypanel'>
<br>
تــــعديل بيـــانات الـــمدير بنـــجاح
<br>
<br>
</div>
</center>
<meta http-equiv='refresh' content='4; url=?cpages=users' />
");
}
}
and here is the edit form code :
if ($_REQUEST['euid']) {
$edituid = $db->query("select * from user where user_id='$editu'");
$redit = $edituid->fetch(PDO::FETCH_OBJ);
echo "
<form action='?cpages=users' method='post'>
<table width='100%' align='center' cellpadding='10' cellspacing='0'>
<tr>
<td class='tbl' colspan='2'>تعديل بيانات مدير</td>
</tr>
<tr>
<td class='tblrl' align='left'>اسم المدير : </td>
<td class='tblrl' align='right'><input type='text' name='eusername' value='".$redit->username."'></td>
</tr>
<tr>
<td class='tblrl' align='left'>كلمة سر المدير : </td>
<td class='tblrl' align='right'><input type='text' name='epassword' value='".$redit->password."'></td>
</tr>
<tr>
<td class='tblb' colspan='2' align='center'><input class='buttons' type='submit' value='تعديل'/></td>
</tr>
</table>
<input type='hidden' name='edit' value='user' />
</form>";
}

Answer 1

You are not passing the userId in the form
change
<form action='?cpages=users' method='post'>
to
<form action='?cpages=users&euid=" . $_GET['euid'] . "' method='post'>

Answer 2

your problem is here in the form in this line
<form action='?cpages=users' method='post'>
your taking it to users page but there is no euid in there so just add
&euid=" . $_GET['euid'] . " to get it to work fine
