Hi, if you just need the referrer to identify the enquiry comes from, you can take a small part of code from the link you provided. Put it to a plugin. This is the cleanest way an you can turn it on and off ;). I justed tested it and it works with caldera 1.7.6. (should also with the newer ones) …and actual WP Ver.

Small manual:

1. put a hidden field to your (copied) form an remember the field_id.
2. make a Dir in your pluginfolder called ie ‘caldera-forms-send-referrer’
3. make a php file called ‘cf-send-referrer.php’
4. put some code to this file ie like this and change the field_id to yours:

<?php
/**
 * Plugin Name: Caldera Forms — Send referrer by hidden field
 * Plugin URI:  https://calderaforms.com/doc/caldera_forms_submit_post_process/
 * Description: Just puts the referrer to an hidden field
 * Version:     0.0.1

 * Author URI:  http://calderalabs.org

 */

// add action

add_action( 'caldera_forms_submit_post_process', function( $form, $referrer, $process_id, $entry_id  ){

	//make sure to set your field ID here, where to put the referrer.
	$field_id = 'fld_1234567';

	//get referrer 
	$ref_url = $_SERVER["HTTP_REFERER"];

	//change value
	Caldera_Forms::set_field_data( $field_id, $ref_url, $form, $entry_id );

}, 10, 4 );

5. activate the plugin
6. test it!

Good luck

perhaps I misunderstood … :/

okay, new question: Has every course its own slug in the permalink? If not the referrer might not really help you.

With much more work you can do it a different way. Set each link to the form with some kind of ID/name to identify the course:

Ie http://www.abc.com/enquiry/?crs=12345

Now you can prefill your hidden field with {get:crs} as standard. You’ll get 12345 as value with the example above.

This doesn’t use the referrer to identify the enquiry an you have to set each link manually … quite a lot of work providing up to 100 enquirys

and an other last solution:

if you embed the whole form via shortcode to your pages, you can set a default value to the needed field:

https://calderaforms.com/doc/set-field-defaults-shortcode/

This might work displaying always the same form for each type of enquiry while setting your hidden field to the desired value via shortcode.

Good luck with this 😉

I am in need of the same thing, if you will know solution, please write here
