How can I make my Landing Page capture a URL query string and insert it into a SINGLE hidden Form field?

To capture an entire URL query string and insert it into a SINGLE hidden field in a form:

1. Make sure you have created the custom field that you would like to use as a HIDDEN form field to receive the query string data.
   
   
2. Add an ID to the hidden field you plan to populate with data:
   

   <input name="x_udf_leadsource79" id="x_udf_leadsource79" type="hidden" />

    

3. Add script to populate the field with the query string:
   

   <script type="text/javascript">
   if(window.location.href.indexOf('?')!=-1){
   document.getElementById('x_udf_leadsource79').value = window.location.href.slice(window.location.href.indexOf('?') + 1);
   }
   </script>

   
   

   Note - The script must appear AFTER the target <input> in the code.

    

4. Complete code will look similar to this:
   
   Hidden fields in form:
   

   <input name="x_udf_leadsource79" id="x_udf_leadsource79" type="hidden" />

   
   Script at end of page that populates field with query string data:
   

   <script type="text/javascript">
   if(window.location.href.indexOf('?')!=-1){
   document.getElementById('x_udf_leadsource79').value = window.location.href.slice(window.location.href.indexOf('?') + 1);
   }
   </script>

    

5.  Data in eTrigue record will look like this:
