Contact form 7 email subject should be post title

1. Haven’t used it before, but this plugin claims to work for your purposes: https://wordpress.org/plugins/contact-form-7-dynamic-text-extension/

   You will then create your mail link to contain the post title via a query parameter with (maybe with http_build_str()), so that your URL becomes like:

   http://example.com/contact-us/?title=my+post+title
   

   After which you have to create the new CF7 tag as such, to auto-populate with the $_GET variable.

   [dynamictext post_subject "CF7_GET key='title'"]
   

2. Solved with this code:

   <?php
   if( $_SERVER['HTTP_REFERER'] !== '' ) {
       $referer = $_SERVER['HTTP_REFERER'];
       $id = url_to_postid($referer);
       $subject = get_the_title($id);
   } else {
       $subject = '';
   }
   ?>
   

   input field:<input id="post-referer" value="<?php echo esc_attr($subject); ?>" type="hidden">

   then used jQuery to fill up the subject field from ‘post-referer’ field’s value.

3. You need to install Contact Form 7 Dynamic Text Extension and use fields in your form this way.

   CF7:

   [dynamictext post_subject "CF7_GET key='title'"]
   

   The key is the name of parameter of your url.
