Variables in URLs

Zardooloi

I have been able to set a variable on a page so that it is visable in the URL by tacking ?variable=value at the end of the header I am using.

Now I would like to have my the page that I verify the log in on to check for the URL variable and react accordingly.

I have been using if than statements, but I have not been able to get the page to use the variables. I have been using the following:

if ($variable="value")
{
header("location: /contact.php");
}

Any suggestions as to how I can use the URL to regualte content?

Thanks!

if ($variable == "value"){
header("Location: contact.php");
}

when you use a single = , you set a variable to a value, which will always be true;
when you use == it compares

to get your URL variables just use $variable = $_GET["variablename"];

Thanks, I changed the single = to a double ==

This is how I have been trying to use the variable, to send the user to another page....

if ($wannago == 1)
{
header("location: /contact.php");
}
elseif ($wannago == 2)
{
header("location: /modindex.php");
}
else
{
header("location: /index.php");
}

The result is that the user goes right to the index.php page.

I tested the wannago variable on another page and it worked, so I'm not sure why the redirect isn't working.

Use absolute URLs for the location header. It may or may not fix your redirect, but it is a step in the right direction by following HTTP 1.1.

check how your setting $wannago,
////
else
{
header("Location: /index.php");
}
will be used if $wannago isnt set or is set to something invalid.

echo $wannago;
somewhere and see what it's displaying
use //// to comment out the header command

echo $wannago; 
if ($wannago == 1)
{
echo "wannago is 1";
////header("location: /contact.php");
}
elseif ($wannago == 2)
{
echo "Wannago is 2";
////header("location: /modindex.php");
}
else
{
echo "Else was used";
///header("location: /index.php");
}

Else was used.

So my variable isn't set properly. This is all I did:

<?php
if (isset($_COOKIE["m_user"]))
header("location: /contact.php");
else
header("location: /profile.php?wannago=2");
?>

This is in a different php page.

rulian

so in your profile.php page you would need to use the $_GET method to retrieve the variable from the URL

just put this at the top of the page before you actually use the variable
$wannago=$_GET["wannago"];

I am still getting "Else wsa used"

Could this be because I have a login check page between the hotlink and the destination page? The check login page redirects and that is where I put the wannago=2 code.

Thank you, by the way, for all your help!
