Question

I wrote some code as a start for a username and password registration page but i cant get the first bit to work. The page with the forms corresponding to the variables at the top work fine but when redirected to this page it just gives a blank white page.

I seem to get this error every time i write some code that is not just basic echo or something like that… Can someone tell me what is wrong with the code and is there any good php editor where you can see error messages or somethilng like that?

This is not the first time i get the same blank page error and i would love to know what i’m doing wrong.

<?php
$user = $_POST["username"];
$pass = $_POST["password"];
$conf_pass = $_POST["conf_password"];

$con = mysql_connect("localhost", "webuser1", "12345");
if (!$con) {
  die('Could not connect: ' . mysql_error());
}

if($pass != $conf_pass) {
  echo ("passwords don't match, <a href="./reg_form.php">return</a>");
}



mysql_close($con);

?>

A blank white page often indicates a 500 Internet Server Error, which usually means you have a syntax or other error in your code.

In your case the error is in the quotes, try changing to:

 echo ("passwords don't match, <a href='./reg_form.php'>return</a>");

I suggest turning on error reporting in your code, or you can check your error log, this will tell you what the problem is and the line number.

error_reporting(E_ALL);
ini_set('display_errors', '1');

Also, if using Firebug, you can see the 500 Internal Server Error on the Net tab.
