form validation (unique num prefs)

woopwoop · 01-01-2012, 09:16:33 AM

This has been hurting my brain for a while - please help if you can.

I have a form that is constructed by php based on the number of items there are in a table (mysql).

The form is basically a way for me to collect user's preferences and store them in a database.

I don't know the number of options there'll be, because php finds this number out and then lists the items in a form with a small text box next to each item.
All of this works so far.

I want people to just enter a number value next to each title to indicate their preference. So if there were 15 items, users would enter 1-15 in their order of preference.

The problem is that I need validation that wont allow the form to be submitted if there are blanks, duplicates and the numbers entered must go from 1 to (however many number of items there are in the table in the db).

If anyone can help me with this I'd really appreciate it.
