When you upload an attachment from the post edit screen, WordPress set the current post ID as the post_parent of the attachment. And that’s how you get these attachments: $post_ID = 123; $attachments = get_posts( array( ‘post_type’ => ‘attachment’, ‘post_status’ => ‘inherit’, ‘post_parent’ => $post_ID, ‘post_per_page’ => -1, ‘post_mime_type’ => ‘image/*’ ) ); foreach ( … Read more
The second parameter on wp_editor is the “metabox” field id/default name and you need to put this in the “update_post_meta” for wordpress to know what to save or specify the correct textarea_name.

It’s a bit simpler to let WordPress handle generating the permastruct when you register your post type. I also recommend against using global variables, there are API functions for most of what you need to accomplish with the rewrite class. function magazine_issues_rewrite() { add_rewrite_tag( ‘%issuenumber%’, ‘([^&]+)’ ); add_rewrite_tag( ‘%issueyear%’, ‘([^&]+)’ ); // post type registration, … Read more
Adding custom fields to the Quick Edit screen – puzzled about the column concept
empty checks for several things: “” (an empty string) 0 (0 as an integer) 0.0 (0 as a float) “0” (0 as a string) NULL FALSE array() (an empty array) $var; (a variable declared, but without a value) In short, you are running a check if the value evaluates to false or does the value … Read more
