harafa Posted February 13, 2009 Share Posted February 13, 2009 Hi all, I'm trying to write PHP code that lets me check if a user is already registered (exists in my batabase) so he can log in, or not registered so he has to. In other words, i check for the user's ID in my database, if found --> go to next PHP page if not --> do nothing (he has to go back to log in) So, now i need to put a button (to go to the next PHP) in the if statement, so this button will be valid only if the condition (user already exists in db) is true... Is that possible ????? can i put a button inside the IF scope in PHP? if it isn't possible, what else can i do?

Caesar Posted February 14, 2009 Share Posted February 14, 2009 You really don't want to do it in 100 different PHP pages. Instead, use methods (See OOP) or functions...all within a single PHP page. That being said, it's possible to display anything you want on a conditional basis. What you're asking is basically the basics of if/else 101. Something like.... <?php function loadpage($var) { // Your code here } if($_SESSION['loggedin']) loadpage('members'); else loadpage('login'); ?> There's of course different approaches, techniques...etc. But yes, more than possible.
