PHP header redirect not working

[n3xtgensystem]

I have an html login page. Once a user is verified through the PHP page they get redirected to another page. For some reason once I have validated that the user exists I get the message that is was successful but the page will not redirect. This is my script I use on my HTML page to pass the parameters:

 

			$(document).ready(function() {
			$('#submit').click(function() {
				var username = $('input[name=username]');
				var password = $('input[name=password]');
				var data = 'username=' + username.val() + '&password=' + password.val();

				.ajax({
					url: "login.php",
					type: "GET",
					data: data,
					cache: false,
					success: function() {
						alert("SUCCESS");
					}
				});
				return false;
			});
		});

 

And this is my PHP page:

 

			<?php	

			$username = ($_GET['username']) ? $_GET['username'] : $_POST['username'];
			$password = ($_GET['password']) ? $_GET['password'] : $_POST['password'];

			if ($_POST) $post=1;

			$userFound = false;
			$memberId = "";

			// Create connection string, Note, params are as follow
			// mysql_connect(databaseLocation, username, password)
			$con = mysql_connect("localhost","root","");
			if (!$con)
			  {
			  die("Could not connect: " . mysql_error());
			  }
			mysql_select_db("memberdb", $con); 
			// SQL Query
			$result = mysql_query("SELECT memberId, firstName, lastName, username, password FROM member");
				while($row = mysql_fetch_array($result))
				{
					if ($username == $row["username"] && $password == $row["password"])
					{
						echo "<h1>Welcome " . $row["firstName"] ." ". $row["lastName"]  . "! </h1></br>";
						$userFound = true;
						$memberId = $row["memberId"];
					}
				}
			// If User is found, continue on to next page, if not redirect to index.html
			if ($userFound)
			{
				echo "<h2>Login Successful</h2>";
				echo "<h3>Page will redirect</h3>";
				header( "url=menu.html?memberId=" . $memberId);
			}
			else
			{
				echo "<h2>LOGIN FAILED</h2>";
				echo "<h3>Page will redirect</h3>";
				header( "refresh: 1; url=index.html#loginPage");
			}					
		?>

 

It does the echo successfully but hangs on the part where is says :

 

header( "url=menu.html?memberId=" . $memberId);

 

How can I get it to redirect?

 

Thanks

For one, you should read the sticky on the forum about header errors.

 

Another, you should check out header in the manual, and probably Google more on HTTP headers and acceptable values.

You can not echo/display out anything before calling header()

 

absolutely nothing

 

I'll refer you to this page for more on it

http://www.phpfreaks.com/forums/index.php?topic=37442.0

 

also, does you html page read php code for that $_GET request of memberId?

 

if not edit your .htacess with AddType application/x-httpd-php .htm .html , save and restart the server

Because that's not how you redirect.

 

This is how:

header("Location: menu.html?memberId=" . $memberId);

From the PHP.net manual on header()

 

Note:

 

HTTP/1.1 requires an absolute URI as argument to » Location: including the scheme, hostname and absolute path, but some clients accept relative URIs. You can usually use $_SERVER['HTTP_HOST'], $_SERVER['PHP_SELF'] and dirname() to make an absolute URI from a relative one yourself:

 

<?php

/* Redirect to a different page in the current directory that was requested */

$host  = $_SERVER['HTTP_HOST'];

$uri  = rtrim(dirname($_SERVER['PHP_SELF']), '/\\');

$extra = 'mypage.php';

header("Location: http://$host$uri/$extra");

exit;

?>

Thanks. I have read the sticky and manual and tried to use:

 

header("Location: menu.htm");

 

$host  = $_SERVER['HTTP_HOST'];

$uri  = rtrim(dirname($_SERVER['PHP_SELF']), '/\\');

$extra = 'menu.html';

header("Location: http://$host$uri/$extra");

exit;

 

And it will redirect to the correct page the URL does not change. It still says its on the login.php page even though it showing the menu.html page. I have tried other browsers to see if it works but still the same thing.

[scootstah]

Hmm. That shouldn't happen. If the header wasn't sent, the page should redirect thus changing the URL.

 

Does the same thing happen with this?

header('redirect:0; url=menu.html');

[xyph]

That seems like client side behavior.

 

When I use header( 'Location: ...' ) the destination URI shows up in my browser.

It is always a good idea to place an exit after the header command to prevent further action in the script.  Header outputs the header, but does not stop the processing of the rest of the script.

 

<?php ...

// Prevent non-logged in users from issuing commands.
if (! $loggedInUser) {
header( "Location: /login.php");
exit;
}

// User is logged in, make changes requested (like delete account)

 

If you don't, the code will continue on behind the scenes which might be a big surprise if you don't know it.

[QuickOldCar]

placing exit; at the end is not always a good idea, you may want to continue processing the script

Your header redirect is not working because your processing the form using ajax.  Your header redirect is just going to cause the background ajax request to be redirect, not the page that is displayed.  If you want to redirect the page displayed, you need to output something which your ajax success handler can pick up and test for and then use JS to do your redirect.

 

ex:

echo json_encode(array(
   'response' => 'redirect',
   'url' => 'http://www.example.com'
));

 

				$.ajax({
					url: "login.php",
					type: "GET",
					data: data,
					cache: false,
					success: function() {
						//Get the json response via some means
						//then...
						if (jsonObj.response == 'redirect'){
						      window.location.href = jsonObj.url;
						}
					}
				});
