bh Posted August 6, 2010 Share Posted August 6, 2010 Hi, Use isset to decide is the variable is set and not null. Eg like this: if (isset($_POST['submit'])) { } Link to comment https://forums.phpfreaks.com/topic/209966-php-coding-errors/#findComment-1095923 Share on other sites More sharing options...

JasonLewis Posted August 6, 2010 Share Posted August 6, 2010 Take a look: if(isset($_POST['submit']) No parenthesis... You also don't need this: if (isset($_POST['submit'])) { } Because you're doing nothing there. Above you have the checks for the variables. Preferably, I'd re-think how you're going about it. Use the first option. if(isset($_POST['submit']){ $fullname = $_POST['fullname']; $username = $_POST['username']; $password = $_POST['password']; $repeat_password = $_POST['repeat_password']; // Do stuff with form data, validate. Then register. } Link to comment https://forums.phpfreaks.com/topic/209966-php-coding-errors/#findComment-1095933 Share on other sites More sharing options...
