On my site I am building, I have a front-end form that new users will fill. Once they have a published form, I will change their user type/permission on the site.
I would like to know how to prevent a signed-in user (regardless of their permission) from being able to fill in a particular post form more than once. In case you need my website, it is hidden link.
Alternatively, if you want to use Toolset, you can create a view and filter the view to display posts by adding the "post author" filter equal to current loggedin user. So, you can tweak it if there is post found, you should not show anything and if there is no post found, with the no post found section, you can add the Toolset form shortcode to this section using which user can submit the entry.
Thank you for your prompt response. I downloaded the plugin, but it only lets you create a rule for one user role and I have two that need protecting.
I found a workaround in that I have my two forms visible to one standard user role and then once their permissions change on the site, they can’t see the forms anymore. I would have liked a formal way to block any more than 1 submission but this does the trick! Thanks!
