consulta sql no elimina la columna

[matt_1985]

tenias problemas con las comillas ,

Código PHP:

<?php
 
include($_SERVER['DOCUMENT_ROOT'] . '/config.php');
 
session_start();
 
$id = $_GET['id'];
 
if (isset($_SESSION['id'])) {
 
$sql = mysql_query("SELECT * FROM muros WHERE id='".$_GET['id']."'");
$row = mysql_fetch_array($sql);
$yailol = mysql_num_rows($sql);
if ($yailol == 0){
header ("Location: ".$url."/home.php?noexiste");
}else{
$consultar = mysql_query("SELECT * FROM megusta WHERE idpub='".$_GET['id']."'");
$ssas = mysql_fetch_array($consultar);
if($ssas['username'] == $_SESSION['username']){
header ("Location: ".$url."/home.php?yanotegustaa");
}else{
 
 $query = 'DELETE FROM megusta WHERE idpub="'.$_GET['id'].'" AND username="'.$_SESSION['username'].'"';
mysql_query($query) or die(mysql_error());
 
header ("Location: ".$url."/home.php?yanotegusta");
}}}else{
 
header ("Location: ".$url."/index.php");
 
}
 
?>
