Problem: I have a Form that creates parent posts. There is a generic checkbox in the Form. If the checkbox is checked, I would like to automatically create a child post.
Solution: Use the cred_save_data API to create a post automatically, use the toolset_connect_posts API to automatically link the new child post to the new parent post, and test the checkbox by testing if the slug key exists in the $_POST superglobal.
I am trying to sort view results using a M2M intermediary post field but it shows "No results found".
Solution:
Views plugin is using wordpress class WP_Query to query the posts, so if you are ordering the result by custom field, then all posts should have the value in this custom field.
In your case, I suggest you setup a post view, query posts of the intermediary post type, order result by the intermediary post field, in the view's loop display the related(parent) post information:
Problem: I would like to update my site to Types 3+, and migrate to the new relationships system. After updating the plugin, I cannot find the relationships migration button.
Solution: If no post relationships existed in the old system, there is nothing to migrate. Create new post relationships and begin using the new relationships system.
