replacing $product->get_files();

Thanks @mensmaximus, that’s what I thought.
Using the latest WooCommerce (3.0.4) and WordPress (4.7.4) with no other plugins, twentyseventeen theme.

I have indeed, var_dump($product); spits out this:

Ok, so it was to do with how the data is being saved to the database (another part of my own code).
I have extra fields for downloadable files, which is saving, but somehow it’s saving differently to the standard file data… Not sure why at this point.

I guess my initial question should have been “How to store extra downloadable file data in WooCommerce 3.x”…

If you could point me in the right direction for this, I would be greatly appreciative.

Hi @mikejolley,

I hope you can help me with this!
I am soooo close I think.

I am trying to send the extra fields to the set_downloads function, but I can not seem to get it to work.

I reached out to Woo developers and was told it’s not possible… but I don’t believe that.

I have everything working except the actual save of the new fields data for each downloadable file. I have a field for icon (URL field), description (textarea) and size (text field).

I have the following code working, but if I deactivate my plugin, then the standard file name and file URL for simple products is gone when I use get_downloads() to retrieve the data.

The variable data saves just fine and the file name and URL are still there if my plugin is removed which is ideal.

I’ve tried so many things that just don’t seem to be working when it comes to passing the new file fields to set_downloads().

Pleeeeeease help me figure this one out. Here is the code that seems to work ok for variable products with downloadable files, but not simple. Both of these are still using the update_post_meta, and additionally the simple product is using serialize() because I can’t get it to work without.

Thanks in advance for any help you can provide!

function bodhi_wedpf_save_meta( $post_id ) {

	if ( $_POST['product-type'] == 'variable' ) {

		foreach ( $_POST['variable_post_id'] as $variation_id ) {

			$data = get_post_meta( $variation_id, '_downloadable_files', true);

			if ( $data ) {

				$final_array = array();
				$j = 0;

				foreach ( $data as $key => $value ) {

					$final_array[$key] = array(
						'id' => $key,
						'name' => $_POST['_wc_variation_file_names'][$variation_id][$j],
						'file' => $_POST['_wc_variation_file_urls'][$variation_id][$j],
						'description' => $_POST['_wc_variation_file_descriptions'][$variation_id][$j],
						'size' => $_POST['_wc_variation_file_size'][$variation_id][$j],
						'icon' => $_POST['_wc_variation_file_icon_url'][$variation_id][$j],
						'previous_hash' => ''
					);

					$j++;
				}

				update_post_meta( $variation_id, '_downloadable_files', $final_array );

			}

		}

	} else {

		$data = get_post_meta( $post_id, '_downloadable_files', true );

		if ( $data ) {

			$final_array = array();
			$i = 0;

			foreach ( $data as $key => $value ) {

				$final_array[$key] = array(
					'id' => $key,
					'name' => $_POST['_wc_file_names'][$i],
					'file' => $_POST['_wc_file_urls'][$i],
					'description' => $_POST['_wc_file_descriptions'][$i],
					'size' => $_POST['_wc_file_size'][$i],
					'icon' => $_POST['_wc_file_icon_url'][$i],
					'previous_hash' => ''
				);

				$i++;
			}

			update_post_meta( $post_id, '_downloadable_files', serialize( $final_array ) );

		}

	}

} // End of save meta function. bodhi_wedpf_save_meta( $post_id )
add_action( 'woocommerce_process_product_meta', 'bodhi_wedpf_save_meta', 1000, 1 );

Thanks Mike, not to worry.
I have it working with update_post_meta instead.
