Problem with reading form input that contains url

Hi,

I have a GET method form with one input field for user to enter an url, including "http://". When the form is submitted, an error page is showing up because the url in the address bar is having two "http://"s.

Here is the example:
http://www.mywebsite.com/processform.php?userinput=http://www.userswebsite.com

How do I solve this problem? Thank you.

 

You can take off the http:// in the response and leave the url like www.site.com and then do this in php, at the top of the page. Also, I recommend using a post variable.

<?php header('location: '.$_GET['userinput']); ?>

Code (markup):

 

Thanks LeetPCUser for your reply.

But in my case, I need both to include "http://" and to use GET method.

Anyone else might know? Thanks.

 

Here is my example:
Try search "http://www.google.com"(without quotes) on my blog (www.bloggergps.com),
it gets redirected to the front page.

I tested on some other sites with that theme. They work fine.

I think the problem come from my web hosting. I am currently hosted on hostgator.

Does any hostgator subscribers have this sort of problem? Thank you.
