OK, seven days and no reply… I guess I need to ask the same question from another angle.
Here’s the situation:
I am using Exec-PHP plugin to execute PHP scripts on content pages. After I paste the script:
<?php
atropos_custom_meta_box ();
?>
anywhere in the page, the form that belongs to Atropos plugin appears.
Now my question is how to setup a custom field to do that instead? Then I could use this custom field with Gravity Forms (I guess).
