Topic Tag: Post-relationship

Problem: I have some custom code that uses types_child_posts to get a list of child posts. Then I am able to use the $post->fields['field-slug'] syntax to display custom post fields from the child post. However, if I use the native WordPress get_posts function to get the child posts, I am not able to use the same $post->fields['field-slug'] syntax to get information about a custom field.

Solution: The native WordPress get_posts function does not return information about custom fields, so you must use get_post_meta to retrieve custom field information about each post returned by get_posts.

$date = get_post_meta(get_the_ID(), 'wpcf-date', true);
echo date('l jS \of F Y h:i:s A', $date);

Problem: I have custom post types Enquires and Team Members. I would like my Guest users to be able to use CRED to create a new Enquires post and select one or more Team Members to associate with the Enquire post. Team Members can be associated with more than one Enquire. What type of post relationship should be used here?

Solution: Many-to-many relationships are designed to allow one or more type A posts to be related to one or more type B posts. These relationships are fairly easy to manage in wp-admin, but they are not as straightforward to manage in CRED forms. Some custom code may be required to create a generic multiselect or checkboxes field that captures a User's selections and applies them on the backend. You can use the cred_save_data hook to accomplish this.
