unset $GET

[c_pattle]

I have a link that sets a get variable that then performs a search based on that get variable.  How after I the page has reloaded with the new search results how can I removed the $GET from the end of the url?  Thanks for any help.

What?

[c_pattle]

Sorry.  For example say I click on a link such as this

 

<a href="index.php?author=fred">Click</a>

 

Then next time I reload the page how do I remove "author=fred" from the url so that the variable author isn't set?

By refreshing the page, do you mean by pressing refresh, or following a link on the page to itself? Do you need the value of the $_GET variable to still be accessible? Why do you actually want to do this?

I want to do this because I have some code at the top of my document that says (this is an example)

 

if(isset($_GET['author'])) { echo ("hello") }

 

This is fine but then if I submit a form on that page "$_GET['author']" will still be set and it will still say hello at the top of the screen.  It's hard to explain but I hope this makes sense.

You could post the data to the page instead of passing it in the $_GET, use $_POST with a form. That way it won't be visable.

 

The other thing you could do is store something in a session variable to say that the hello echo has already happend so don't show it again.

you could mod-rewrite your url in your htaccess file, or if you can't do that, you can do something like

 

session_start();
if ($_GET['x']) {
  $_SESSION['x'] = $_GET['x'];
  header("Location: {$_SERVER['PHP_SELF']}");
  exit();
}

//  perform check and query with session var

Then your form action is setting the querystring. Use <form action="<?=$_SERVER['REQUEST_URL']?>"> or similar. The querystring won't persist unless it's actually embedded in links.
