PHP - Updating multiple rows and tables in one form. What am I doing wrong?

I am creating a very insecure form at the moment so I will fix my post values and secure them when I have it working..  I have a friend that is a Realtor and needs a cpanel to create and modify and delete her property listings.  Well besides the typical record information such as title, summary, and description...  the administrator also has the ability to upload multiple images that associate to that specific listing they were creating.  When you grab the id of the record to modify it, I would like to change a single value by the name of `default`to 1 or 0 that is attached to each image associating with the listing that is currently being edited.  This value represents the default image in the gallery.  When viewing the record from the front end, You have a default image on the left and then the rest of the images in another part of the layout.  

My issue is that before I added this functionality to update multiple rows, I was able to click on submit get my success message and then title, date, price, summary, and description were all updated.  Now when I added in the loop and query to update the multiple records, I can't get to the success message and the multiple records update like they should, but then the rest of the fields don't get updated.  Please help and I greatly appreciate it.
