Made a sign up form with persons last name using checkboxs.
Is their a way using php to check and make sure that they do not sign up twice ?
Thanks
Jack

Hi Jack,
Yes there is. A little mysql database to keep track and php hide the form if their name is in the database.
This example should give you the needed info. I'm checking for ip address but you should be able to tweak it for a submitted name.
Vote Please

Eric,
Thanks for the prompt reply, the mysql database works perfect.
The forms I have been using are saving as csv files in your storage folder.
Is their a way to insert php into one of your files that checks the csv file for duplicates ?

Thanks again
Jack Tindale
