title: How to manage parameter in thick box tb_show function?
body: <p>I am using below script on a form <code>(say, form-A)</code> to load another form <code>(form-B)</code> in thickbox, with values passed by controller.
  First, in <code>form-A</code>, i am selecting one option from dropdown "customerID", then "Add Project" button (with id 'addProject') becomes visible, on clicking which, a thickbox appears with form-B in it. Here, in form-B, i want to pass selected customer. How can I do that?
  I tried below code, and tried to access the <code>$_GET['custID']</code> in controller's <code>manage_project</code> function, but it is showing blank. But when i am alerting the url1 (i have commented below), ID is coming there.
  Below code is in form-A view file.</p>
  
  <pre><code>('#addProject').click(function(){
          var url1='&lt;?php echo SITEURL ?&gt;/xome/invoice/manage_project?TB_iframe=true&amp;height=800&amp;width=700&amp;inlineId=innerDiv&amp;class=thickbox&amp;custID='+$('#customerID').val();
  
          //alert(url1);
          tb_show('Add More Project',url1,'');
      })
  </code></pre>
