$hej = "botox";
echo c2c_get_custom($hej);

echo c2c_get_custom(“‘” echo $hej; “‘”,”)

This gives me an error – can you help me out?

add_filter('the_content', 'add_cfields_to_rss');
function add_cfields_to_rss( $content ) {
  if ( is_feed() ) :
    $content .= c2c_get_custom('event_name', "<p>Event name: ", "</p>\n");
    $content .= c2c_get_custom('event_location', "<p>Event location: ", "</p>\n");
  endif;
  return $content;
}

There are other checks you may want to do in the above code to ensure it only inserts custom fields for certain posts (i.e. posts with empty content, or in certain categories) (the above assumes all posts in the feed). You may also want to add more text, multiple custom fields, or other data, which are also all possible.

Hope that helps.

Thanks!

I made a test with a post that I let as a draft on my site. I dont’ want to publish it so that you can’t see it on my site.

In that post, I used many times your shortcode and it worked for all the custom fields except 1. I don’t know why. Is there a maximum of shortcodes to insert in a post ?
That is to say that in the test post, I have in the content : [custom_field field="Ville" this_post="1" between="" /]

In the post, I do have a custom field key Ville and also a custom field value. Do you have any idea why the value is not printed on the screen ?

The other shortcodes in that post have the same structure and they all work:
[custom_field field="Key" this_post="1" between="" /]

Thank you for your support
