Tell us what you are trying to do? Format a stored date value from a custom field created by another plugin. I see the field in the _postmeta table. Thought there ought to be a way to read it into a view. Maybe not?
Is there any documentation that you are following?
You can work with fields from another plugin—except when they are hidden fields (meaning, their name begins with an underscore).
On the page Toolset > Post Fields there is a button at the bottom "Post Field Control" which can be used to bring a custom field from another plugin under Types control, but not fields which are hidden.
The wpv_post_field shortcode outputs the raw value as stored in the database of any field if it exists, even hidden fields.
I think you will need to register a custom shortcode to output the field in the format you require.
You'll probably want to pass the field name as an attribute, get the corresponding post meta for the current post, convert the timestamp to a string in the required format using the PHP date() function, and return that.
This shows we can, in principle, achieve our goal which is to display and update certain values in the other plugin from our Toolset app (Am I correct?).
I will give it a try and let you know if I need help. May take several days before I get back to you.
Yes, you can read custom fields from other plugins.
If you want to write custom fields from other plugins, i.e. using a CRED form, then you would need to insert a generic field with the field slug and you would need to add the "persist":1 option for it to be saved to the database.
