Advanced Custom Fields: update_field not working?
It does work.
If you’re building a wordpress function that programmatically creates or updates posts while using update_field() you may notice that to retrieve that data elsewhere using the get_fields() function it turns up a blank.
For example when you do this
// Create post object $my_post = array( 'post_title' => 'My post', 'post_content' => 'This is my post.', 'post_status' => 'publish', 'post_author' => 1 ); // Insert the post into the database $post_id = wp_insert_post( $my_post ); // Add field value update_field( "field_name_or_id", "I am a value!", $post_id );
Same goes for simply updating a bunch of fields without creating a new post
This is simple enough and its doing what you’d hoped it would do, however, the problem comes when you try to retrieve the data using get_field() or get_fields(), it simply spits out a blank UNLESS you have gone directly into the WordPress admin area and updated or resaved the post you just created.
I a few years back I found the solution but I don’t remember where on the net i found it so im posting it here.
// This doesn't seem to work so don't use this $fields = get_fields(); // Instead use the built in wordpress function to grab the data $fields = get_post_custom($post_id);
Hope this solves any headaches
