<?php



  if(isset($_POST['login'])){ 
  
  
         $username = $_POST['accountname'];
	 $password = $_POST['password'];

	 $query = "SELECT * FROM users WHERE username = $username AND password = $password"; 
	 $check = mysql_query($query) or die(mysql_error());  
	 $num = mysql_num_rows($check); 

	     if($num == 1){ 
		 $_SESSION['loggedin'] = 1; 
		 echo "logged in!"; 

	     } else { 

		 echo "error";


		 }



}else{ 


    echo "You must log in to view this page."; 

} 

?>

 

This returns with a blank page =/ Not sure what's wrong.

I'm going to go with something you removed from the page for posting it in the forum is preventing the page from executing, such as a require() statement that is failing or there is a parse error in your mysql_connect code.

 

What is the rest of the code on the page?

It is not that we do not like it, it is ok, as long as it is necessary. In this case it was, cause you were not closing the "else" statement bracket to your first if.

And adding the two lines of code in your file for error reporting only helps if the error is not a fatal parse error, which it is in this case.

 

You should be learning php (or learning something new in php), developing php code, or debugging php code on a system where error_reporting is set to E_ALL and display_errors is set to ON before you code is parsed so that php will give you immediate feedback of all type of errors it detects.
