[If possible please rectify this code]

These code files (itemList.php & itemEdit.php) are for "add item" function of an inventory module of a larger web based school ERP.  The add item function primarily does the following. 
(both these files reside in the folder "item" in the root folder.
1. creates a horizontal form to add item to the inventory with three fields e.g "name" "item category(drop down menu)" & "item description" (from top to bottom).
2. creates a general form with the column headers "name" "category" & "action" 
3. under action ( edit & delete) options. 

Now the issue is (1) , (2) (3 only delete) are being executed correctly but when it comes to "edit item", always the last added item is getting edited no matter which item i try to edit.

Both itemList.php & itemEdit.php have been attached along with complete database.php
