I am having the same problem when trying to show a form for creating a new post. I only see the submission button, nothing else. Editing a specific form works.
I have copied the code exactly as is shown on this page: http://www.advancedcustomfields.com/resources/functions/acf_form/
I get this error:
Notice: Undefined index: new_post in /wp-content/plugins/advanced-custom-fields/core/api.php on line 1185 Warning: array_merge(): Argument #1 is not an array in /wp-content/plugins/advanced-custom-fields/core/api.php on line 1185
Update:
Using the fix in this post – http://www.advancedcustomfields.com/resources/functions/acf_form/ the error message is removed, but my form is still not showing. Any ideas?
UPDATE 2!
I was using the documentation for V5… So I had the wrong code!
