I am trying to make an update upload form, but I have 1 problem. For each image I can submit a url for banner link, but here is my problem. If I only want to change the url and let the image be, it changes the image to nothing! How do I tell the db to let the record for the image stand and only update the url? Here is what I have done!
$_POST['image'] should not exist (in a meaningful sense.) $_FILES['image'] would instead. You can check the metadata given by the uploading system in the $_FILES array.
