RE: [PHP] I lied, another question / problem

Example: if I have two fields, Name and Age and they both have errors, I would echo $formerror['name'] and $formerror['age'] Then I check if(!$formerror) { do something...... This would not get done as the above two have errors, which is what I want. The problem still lies with something being returned from the function even if there are no errors. So if(!$formerror) never gets done. Which is the problem. Another question, and not related, how do I kill a session when someone leaves a particular page. Thanks
