i've been working on the same issue for the last few days and i just cannot seem to get it working properly. the code that i am posting is where it stands now, but it has gone back and forth many times with different variations. my goal is to create a forgot password link on my login page that will ask the user to type in their registered email address. if it matches, then email them a random pwd. else, send them an error message. to me, it seems simple enough, but i'm having one heck of a time. i've read many other posts on various forums to try and figure this out on my own, but i either don't get anywhere or i can only get partial results.
as it stands with the code i have below... the error arrays seem to work okay as i'm unable to submit an email without @ or . and i cannot leave the field empty. however, as long as i include the @ and . then the page accepts it, and sends me to the home page as if everything is okay. i have left out the mail processing script on this one because i'm trying to first figure out how to distinguish whether the email submitted by a user is in the database or not and only then should the user be taken to the home page.
any help would be great, as i mentioned i'm pretty much going in circles.
