I needed to show any custom field for a post that had a certain setting on it. This way if down the line the client adds more custom fields they want to be shown, no code would need to be added to show the new fields. They would show if they had the setting checked off.
I’m not sure there are easy functions for checking a setting on a field without getting all the settings.
Here is how I did it.
First I had to make the setting:
//add new field called special
function ign_admin_field_settings( $field ) {
acf_render_field_setting( $field, array(
'label' => __( 'Special' ),
'instructions' => 'If this field is a special field make sure to check this off so the field shows under the special section.',
'name' => 'special',
'type' => 'true_false',
'ui' => 1,
), true );
}
add_action( 'acf/render_field_settings', 'ign_admin_field_settings' );
Once this setting was in place, whenever I made a custom field I could check if it was “special”.
On the post in the template file, I then got all fields with the setting “special” like this:
$all_fields = get_fields(); //gets all fields
foreach ( $all_fields as $field => $values ) {
//get the field and all it's settings
$field_settings = get_field_object( $field, get_the_ID() );
if ( isset( $field_settings['special'] ) && $field_settings['special'] ) {
//do stuff with $field_settings. Output this special field.
}
}
Figured this might help someone else out there. It’s really useful
I do wish there was an easier way to get a fields setting without having to get everything else in the field.
