check if value exists

Posted on 16th Feb 2014 07:03 pm by admin

I have googled this for a while and I am getting lots of different results. Is there a standard method used for checking to see if a value exists in a database before inserting a value? I have a form, you type your name and push submit, it inserts the name into the database and then the name shows up in a list. Right now, it accepts the same values. I want to add a check to say

if name exists, do something
