I have a CPT with a Repeatable group.
There is a bunch of fields inside it but one of them is a selecting field containing "Version 1", "Version 2", "Version 3".
I need to be able to enter only once each version.
Let me make sure I've understood what you are asking.
If your CPT has a repeatable field group, when editing a post you can add multiple groups of fields.
One of the fields in the group in your case is a select field with 3 options.
And you requirement is that if an option has already been selected in a previous group, it should not be possible to select it again in another group, yes?
Is the data being entered in the back-end edit screens or with a front-end form?
Any solution will certainly involve custom code, but if you can confirm the above, we might be able to give you some pointers as to how you might go about it.
I'll finally work with 3 relationships.
So to explain more clearly I have a CPT "Movie", and a CPT "Versions"
I've made 3 relationships between both : Version1, Version2 and Version3 relationships (1 to 1).
On the page of a movie I need to display content1 if "Version1" relationship exists (so I need to use conditional display to check the existence of the relationship between this "movie" and "Version1"). How can I achieve that ?
If the relationship does not exist I'd like to display button to add the relationship AND create the Version post at the same time. Do you understand what I'm trying to do ?
If you can share the details where you added your form and test steps about how exactly you want to validate the form - I will review and check what would be the best possible option.
*** Please make a FULL BACKUP of your database and website.***
I would also eventually need to request temporary access (WP-Admin and FTP) to your site. Preferably to a test site where the problem has been replicated if possible in order to be of better help and check if some configurations might need to be changed.
I have set the next reply to private which means only you and I have access to it.
