Snippet | Simple Fields

I actually wrote about this back in April, but it’s such a nice feature that it’s worth mentioning again (also: I had forgot about this myself!):

You can use PHP to set the Post Connector for a post. This has some nice benefits:

Post Connectors can be set automatically (no user has to select something is a dropdown)
Post Connectors can be set based on Post ID, Tags, Categories, what ever you want or need
If you set the Post Connector using code you can then hide the post connector dropdown completely from the edit post screen = much cleaner and more easy to use interface

Some code examples to get you started:

<?php /** * Set post connector for a post using PHP. * * This way it's possible to select a post connector for posts based on their ID, categories, tags, post type, and so on * * This function is using the filter simple_fields_get_selected_connector_for_post that is called when * simple fields determines what connector it should use for each post. * It passes the connector slug and the post object and you should return the slug of the conector that you want to use. * */ function example_simple_fields_modify_connector_for_post($connector, $post) { // Some examples to set the post connector comes here // Plesae note that your're not limited to these, // you can basically check everything for a post, like terms, categories, featured image, title... if ( "attachments" === $post->post_type ) { // If post type is "attachments" then use the attachments-post connector $connector = "post_connector_attachments"; } else if ( 72 === $post->post_parent ) { // if post has a parent post with id 72 then use another connector $connector = "my_other_post_connector"; } else if ( "about" === $post->post_name ) { // if post has a the slug "about" $connector = "about_page_post_connector"; } return $connector; } add_filter("simple_fields_get_selected_connector_for_post", "example_simple_fields_modify_connector_for_post", 10, 2); /** * By default Simple Fields shows a meta box on the edit post screen with a dropdown with * all the post connectors that are possible to set for that post. * * By using the filter "simple_fields_add_post_edit_side_field_settings" we can hide that box * and making the GUI a bit cleaner. * * Works best if you use the simple_fields_get_selected_connector_for_post-filter above to set * the post connector using PHP, since then the user should not be able to try to change the * connector to something else. * */ function example_simple_fields_modify_post_edit_side_field_settings($bool_add, $post) { // Don't show the dropdown if the current post has id 123 if ( 123 === $post->ID ) { $bool_add = false; } return $bool_add; } add_filter("simple_fields_add_post_edit_side_field_settings", "example_simple_fields_modify_post_edit_side_field_settings", 10, 2);
