post-meta

Trying to get file name

Your meta field contains the ID of the attachment, you need to fetch that ID, then get the filename using that attachment ID. $doc_id = get_post_meta( get_the_ID(), ‘pdf’, true ); $filename = basename( get_attached_file( $doc_id ) ); echo $filename;

trying to do if post meta !=0

The reason you have a problem is 0 is also considered equal to false, when the get_post_meta call returns false, it’s also the same as being equal to 0. if( !get_post_meta( $post_id, ‘some-non-existant-field’, true ) == 0 ) Would be the same as … if( get_post_meta( $post_id, ‘some-existing-field’, true ) == 0 ) ..the only … Read more

Create a Metabox that behaves Like a Taxonomy Box

i ended up building a plugin that enforces radio buttons for any taxonomy. http://wordpress.org/extend/plugins/radio-buttons-for-taxonomies/ for the project in question i will probably also save the taxonomy as meta. sucks that i need/want half the ability of taxonomy (knowing other available terms, etc), but need the sorting by meta.

How trigger to save post when updating post meta

I’ve used this to insert posts with ACF/postmeta data successfully, but please test it on a development site before deploying live, there might be some terrible assumptions. Generally, it assumes that you only have each name once, that is “myfield” doesn’t exist in two field groups with different meanings. $mycustomvalue = 123; $f_mycustomfield = get_acf_key_by_name(“mycustomfield”); … Read more
