Hi all,

I need a big help..I was struggling about 3 /more days with this code..It is not giving me the result I want.It is not that difficult thing.What I want is to display the values in database(name,description,image) according to the id selected. And then it can be edited if want ,after that I want to submit the new values to the database.But it is not running.As I see there is no error in the query ,so I think something wrong with the php code.

Can someone go through it and help me please.Its a great help.Thanks.

<?php
session_start(); //Session Starts.
if(!isset($_SESSION['valid']) || $_SESSION['valid']!="yes"){
header("location:../../admin/adminLogin.php");
//print "invalid login";
exit();
}

require_once '../../connect.php' ;

if (isset($_POST['btnSelectId']))
{

		$cid         = $_POST['catId'];
		
		$sql="SELECT * FROM tbl_category WHERE cat_id ='$cid'";//search using category id 
		
		$result = mysql_query($sql) or die(mysql_error()); //Execute query
		$cat_row = mysql_fetch_array($result);//row containing the row values
		$name = $cat_row['cat_name'];//assign name field value of the database to a variable
		$description = $cat_row['cat_description'];	//assign description field value of the database to a variable  
		$image = $cat_row['cat_image'];//assign image field value of the database to a variable

on lines 44 and 49 you have: UPDATE tbl_category SET cat_name ='$name2' WHERE cat_id = '$name' If I am not mistaken it should be ... WHERE cat_id=$cid Also, on line 10 put the following: $cid = isset($_POST['catId']) ? $_POST['catId'] : 0;

0

and On line 14 you are using $cid for $_POST;
and again on 29 same variable is used (isset($_POST))
$cid = $_POST;
is it working correctly???

What's your point? He is consistently setting the value of $cid to $_POST. If anything, it is redundant. Hence my suggestion to put $cid = isset($_POST['catId']) ? $_POST['catId'] : 0; on line 10. That way he can get rid of lines 14 and 29.

From what I can see, the problem is not $catId, but not using the right variable in the UPDATE statement.
