I have a server script with which i have allowed the user to mark any item as favorite, but i also want another script through which the user can unfavorite the same item if they want and that item should be deleted from their favorite list. I have kept the same table for both favorite and unfavorite code, therefore i have used update query to update the details. For this purpose i have a code, but its not working, as i am new in the programming field would appreciate if someone could provide the correct codes <?php require_once('config.php'); $favorite = $_REQUEST['favorite']; $unfavorite = $_REQUEST['unfavorite']; $id=$_REQUEST['id']; $unfavoritedeal=mysql_query("SELECT * FROM favoritedeals where id='".$id."'"); //favoritedeals is the name of the table if($row=mysql_fetch_array($unfavoritedeal)) { $favorite=$row['favorite']; $unfavorite=$row['unfavorite']; } $myfavorite=(isset($_REQUEST['favorite'])?$_REQUEST['favorite']:$favorite); $myunfavorite=(isset($_REQUEST['unfavorite'])?$_REQUEST['unfavorite']:$unfavorite); $update = mysql_query("update favoritedeals set favorite = '".$myfavorite."', unfavorite = 1 where id = '".$id."'"); if(unfavorite="1" where id='".$id."') { "delete from favoritedeals WHERE id= '".$id."'"; } $posts[0]['message'] = 'favorite list updated'; $selectt = mysql_query("select * from favoritedeals where id = '".$id."'"); $results = mysql_fetch_assoc($selectt); $posts[0]['detail'] = $results; header('Content-type: application/json'); echo json_encode($posts); ?>
