[SOLVED] problem with log in form

[dachshund]

Hi,

 

This log in form is supposed to check if they are already logged in and if they are echo ACCOUNT | LOGOUT. But when they're logged in, it just doesn't echo anything and it's just blank.

 

Can anyone see where i'm going wrong?

 

<?php

if ($_SESSION['uid']){

echo "ACCOUNT | LOGOUT\n";

}else {
     
  	if(!$_POST['submit'] == 'login'){
      	echo "<div id=\"blanket\" style=\"display:none;\"></div>\n";
  	echo "<div id=\"popUpDiv\" style=\"display:none;\">\n";
  	echo "<a href=\"#\" onclick=\"popup('popUpDiv')\">Close</a>\n";
  	echo "<form name=\"login\" method=\"post\" action=\"#\">\n";
  	echo "<p>Username <input name=\"username\" type=\"text\"></p>\n";
  	echo "<p>Password <input name=\"password\" type=\"password\"></p>\n";
  	echo "<p class=\"submitbutton\">\n";
  	echo "<div align=\"left\">\n";
  	echo "<input type=\"submit\" name=\"submit\" class=\"loginformtext\" value=\"Submit\">\n";
  	echo "</div>\n";
  	echo "</p>\n";
	echo "</form>\n";
  	echo "<span class=\"login_text\"><a href=\"#\" onclick=\"popup('popUpDiv')\">LOG IN</a>\n";	
	echo "</div>\n";			
  
   	}else {
  	$user= $_POST['username'];
  	$pass= $_POST['password'];
  
  		if($user && $pass){
		$sql = "SELECT * FROM `users` WHERE `username`='$user'";
		$res = mysql_query($sql) or die(mysql_error());

			if(mysql_num_rows($res) == 1){
			$epass = md5($password);
		    $sql2 = "SELECT * FROM `users` WHERE `username` ='$user' AND `password`='$epass'";
			$res2 = mysql_query($sql2) or die(mysql_error());

			}else {
			echo "USERNAME OR PASSWORD INCORRECT\n";
			}

	   }else {
	   echo "USERNAME OR PASSWORD INCORRECT\n";
	   }

}
}

?>

if ($_SESSION['uid']){

 

use isset or empty

[dachshund]

like this?

 

if (isset($_SESSION['uid'])){

 

 

that returns the same result.

So when they're logged in you see nothing at all? Not even anything echo'd by the else statement?

just my 2c, 

Check your http server error logs.

This may show you something you have missed.
