Thanks for explaining the different purposes of the two filters. I did not grasp that and it obviously explains why they behaved the way they did. I agree this is a very practical example of extending MLA’s functionality to meet a custom need. 👍 When I finally get the site completed I will circle back around and share it here with you so you can see how I leveraged this custom field information.

Hi David,

I have been looking at the function and have a couple of question that may help get me going.

I want to ask you about the function parameters:

mla_evaluate_custom_data_source( $custom_value, $post_id, $category, $data_value, $attachment_metadata )

@param	string	NULL, indicating that by default, no custom value is available
@param	integer	attachment ID for attachment-specific values
@param	string 	category/scope to evaluate against: custom_field_mapping or single_attachment_mapping
@param	array	data source specification ( name, *data_source, *keep_existing, *format, mla_column, quick_edit, bulk_edit, *meta_name, *option, no_null )
@param	array 	_wp_attachment_metadata, default NULL (use current postmeta database value)

1. As I understand it all of these parameters are being passed into this function such that they are available for my custom PHP code to work with.

How do I reference the metadata in the PHP code I will insert in the function? Would my code look something, roughly like this:

if ($attachment_metadata.COMPUTED.Width/$attachment_metadata.COMPUTED.Height>1) {
$custom_value=’Landascape’;}
else
{$custom_value=’Portrait’;}

2. How do I “Call” this function in the MLA settings so that I tell it to populate a custom field I create in ACF called “calculated_orientation”? Is this call specified somehow in the Custom Fields tab of the MLA Admin screen?

Thank you!
