I have created a Custom Field in my wordpress page: eg-custom-link
I would like to output the value of this in the Wordpress editor (not in a php template) If I wanted to echo this in a php template I could use:
<?php $key="eg-custom-link";
echo get_post_meta($post->ID, $key, true);?>
... but in this instance I would like to output the custom field using the wordpress text editor.
