Hyperlink with textbox

Hi

I want to create a hyperlink on my site for client to find there login page(No search of database wanted).
My accounts are uploaded to subdomians.
I want a text box (subdomain) hyperlink:
Example:
(textbox).website.com (click Here)

What I have so far:

<input type="text" value="">.activehosted.com/admin/

Code (markup):

I am reseller for activecampaigns.com and need a page similar to there page http://www.activecampaign.com/login/ (but on my site - don't want iframes)

 

The site you referenced is basically using a fancy select box generated with javascript. You can do the same thing with a plain old html select/option box and some simple javascript. Here you go as an example:

<script type="text/javascript">
function login_load() {
    var domain,subdomain;
    domain = document.getElementById('domain');
    sub_domain = document.getElementById('sub_domain');
    if(sub_domain.value !== "") {
          window.load("http://"+sub_domain.value+domain.options[domain.selectedIndex].value);
    }  else {
          alert("please enter your sub-domain");
    }
}
</script>
<input type="text" value="" name="sub_domain" id="sub_domain">
<select name="domain" id="sub_domain">
<option value=".activehosted.com/admin" selected>.activehosted.com/admin</option>
<option value=".someother.com/admin">.someother.com/admin</option>
<option value=".yetanother.com/admin">.yetanother.com/admin</option>
</select>
<input type="button" value="login" onclick="login_load();">
