direct to wildcard subdomain

[yola]

Hello,
I need your help concerning building a small script which will direct a person to wildcard subdomain.
There should be an input field, a kind of <input name="letters" type="text" /> and it should direct a person to "letters" wildcard subdomain.
What the users write in the input field, it should be a subdomain name, eg. a user writes abc in the input field and then is directed to a subdomain.website.com.
Is it possible to build such a script?
I was looking for a solution for several hours, in vain still... I don't know much php, so if you can, please help me.

Hi yola,

what you can do is use header() to redirect to what ever the subdomain he/ she typed.

ex:

if(isset($_POST['submit']))
{
	if(trim($_POST['letters']) <> '')
	{
		$fullDomain = 'http://'.trim($_POST['letters']).'.domain.com';
		header("Location: ".$fullDomain);
	}
}

make sure you put this on top of your code. Reason been that, when you use header() you cann`t output anything before it.

Hope this solve your problem.

Best regards,
Niroshan
