How to search to edit and delete

[shak]

This is my code so far. When i add the customer i want it to give the customer a unique identifier, something like a quote reference. So when I go on the edit or delete menu's i can type it in and that customer comes up and then I can edit the field i require etc.

Sorry for the layout of the code I couldn't do the tag thingy. (New to the forums )
