[FIXED] Wordpress Contact Form 7 dynamically autoselect dropdown field based on referral url

Issue

I have been working off of these two answers:

Wordpress Contact Form 7 dynamically select dropdown field based on url

Auto-select fields in Contact form 7 based on referral link

Currently, the code below is pasted in the CSS block on the /contact page:

(function($){
$(document).ready(function() {

  //determine the previous page,
  let page = document.referrer, opt='';


  switch(true){
    case page.indexOf(’douglas-h-flint’)>0:
      opt=‘douglashflint’;
      break;
    case page.indexOf(‘john-f-connolly’)>0:
      opt=‘johnfconnolly’;
      break;
    case page.indexOf(‘david-l-walker-jr’)>0:
      opt=‘davidlwalkerjr’;
      break;
  }

  $('select[name=“select-recipient”]’).find('option[value="'+opt+'"]').prop('selected', 'selected');
})
})(jQuery);

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<select name="select-recipient”>
 <option value="">General Inquiry</option>
 <option value=“douglashflint”>Douglas H. Flint</option>
 <option value=“johnfconnolly”>John F. Connolly</option>
 <option value=“davidlwalkerjr”>David L. Walker, Jr.</option>
</select> 

My website is: https://c7n.f22.myftpupload.com/

My goal is that when someone navigates to the /contact page directly from one of these people's individual pages—(/attorneys/douglas-h-flint) or (/attorneys/john-f-connolly) or (/attorneys/david-l-walker-jr)—that the "Inquire with:" dropdown field in the contact form would autoselect their respective name and that when someone navigates to the /contact page from any other page on the site, the "Inquire with:" dropdown field would remain defaulted to "General Inquiry" option.

What am I missing? Or what am I doing incorrectly?

Thank you in advance for any help!

Solution

While the other answer is a good answer, it's not quite WordPress useable as is. Since this is contact form 7, and WordPress, there are a few things wrong with it.

1. Don't re-add jQuery this way <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script> the jQuery library is already included with WordPress.
2. jQuery is loaded in no conflict mode, so you have to initialize first with jQuery and not $
3. You can add your script to your contact form 7 form like this although this is not the absolute best way to do it. It will work without adding a bunch of javascript to another file. There are also easy ways to use wp_add_inline_script to properly enqueue your script conditionally.

So if you add the following to your contact form... it will work.

<script type="text/javascript">
jQuery(function($) {
  //determine the previous page,
  let page = document.referrer, opt = '';
  switch(true){
    case page.indexOf('douglas-h-flint') > -1:
      opt = 'douglashflint';
      break;
    case page.indexOf('john-f-connolly') > -1:
      opt = 'johnfconnolly';
      break;
    case page.indexOf('david-l-walker-jr') > -1:
      opt = 'davidlwalkerjr';
      break;
  }
  $('select[name="select-recipient"]').find('option[value="'+opt+'"]').prop('selected', true);
});
</script>
