I am trying to write a some code to set a restriction on a text box on a form. I want to restrict all users to use this that doesn't have a @iup.edu at the end of there email address. Is there anyway to do this with php? If so how?

is the user already logged in? if so, then just grab the user's email address wherever var you have it in (i'm using $useremailaddress as generic var), get the last 8 chars of it and put that into a var ($checkaddress) and if $checkaddress does not = @ipu.edu then display the text box or do whatever you wanna do.


$checkaddress = substr($useremailaddress,-8);
if ($checkaddress != '@iup.edu') {
/* insert text box here

Please, take the time and do some research and find out how much it would have cost you to get your help from a decent paid-for source. A "roll-of-the-dice" freelancer will charge you $5-$15/hr. A decent entry level freelancer will charge you around $15-30/hr. A professional will charge you anywhere from $50-$100/hr. An agency will charge anywhere from $100-$250/hr. Think about all this when soliciting for help here. Think about how much money you are making from the work you are asking for help on. No, we do not expect you to pay for the help given here, but donating a few bucks is a fraction of the cost of what you would have paid, shows your appreciation, helps motivate people to keep offering help without the pricetag, and helps make this a higher quality free-help community :)
