Refreshing a page adding GET vars.

[DaveRich]

So I am creating an application that requires 3 variables to be passed to some page.php.

I need $_GET['x'], $_GET['y'], and $_GET['z'] to be passed to the page.

I have an if statement that I have created now to catch if any of these 3 vars have not been passed, however I am wondering if it's possible to reload the current page in PHP, appending default values for these variables to the URL.

if(!isset($_GET['x']) || !isset($_GET['y'] || !isset($_GET['z']))
{
      //load currentURL + "?x=1&y=2&z=3";
} 

For example, if someone requests page.php it will automatically change it to page.php?x=1&y=2&z=3.

Thanks in advance! .

Do you really need to reload a page with a default query string? Why not:

if (!isset ($_GET['x'])) $_GET['x'] = '1';

// ...move on knowing that $_GET['x'] has something useful in it.

The reason I was wanting to reload the page with default GET values set is because the page will have two different stylesheets / layouts being used depending on what stage of the application the user is in.

In theory;

If the user goes to the page for the first time, they will select a series of default settings, and then next time the application is run by that user, all of those settings will be remembered.

However, just for default testing purposes now I dont want to have to go to through the lengthy process of creating a "profile" everytime I want to test the second section of the application.

Rather then using PHP I have come up with a temporary solution to just use javascript like this: location.href = window.location + (all arguments here).

Ah, got it. From PHP you could do:

header ("http://www.mydomain.com/?x=1&y=2&z=3");
