product listing: combine and output labels before combined data values

[molywerks]

Any PHP inspectors out there?

[FONT="Arial Black"]Background.[/FONT] I need help with tpl_modules_products_new_listing.php where I am successfully using two custom data fields, model name and style. Note that a style value does not necessarily exist but a model name always does. Thus, I am trying to output and display covering the two possible conditions:

1. model name | style » iPod | Shuffle
2. model » Zune

Note the absence of a style label in the second. This is my trouble, preventing its output when there is no style value.

[FONT="Arial Black"]Question.[/FONT] How do I rework the functioning tpl_modules code shown in purple below so that it outputs labels and data to cover the above two possible conditions?

[FONT="Arial Black"]What works.[/FONT] Figuring out the HTML is easy as is getting the custom data fields to output in display with their labels, but the trouble I am having is the conditional combine and output. Also, I do not mind if a solution involves the code shown in green below which is in the <td>table</td> areas toward the bottom of the modules template file. And yes the configuration table and admin panel are set properly to display the new configuration table rows: PRODUCT_NEW_LIST_STYLE_LABEL, PRODUCT_NEW_LIST_MODEL_NAME and PRODUCT_NEW_LIST_STYLE.

[FONT="Arial Black"]What doesn't.[/FONT] What I've tried is a zen_products_lookup with an if empty statement shown in blue below but my PHP skills are in early beta. Obviously. IOW, I can copy and paste and sometimes manipulate it to get it to do what I want but original coding from scratch is out of the question for me at this stage. I may need examples pointing out where I am going wrong.

Lastly, I will add PRODUCT_NEW_LIST_MODEL_NAME_LABEL components if necessary once I understand how to get the STYLE label working properly.
