Hi, I finally managed to get it working.
the plugin I was modifying was trying to access the field data before it was saved. that’s why it worked with an already published post entering it’s post id number but not with a new one.
the second issue i had have been solved to, i was developing a solution to publish a post to facebook using the advanced custom fields as description value or to set the image of the facebook post, i had a scope problem with that one.
I will try to make that last one into a plugin, i diden’t found any existing plugin that let you use ACF values to publish a post to a social network
