Adding a custom field as a column in product listing

[free hugs]

Here is my problem...

 

We sell power supplies that require fields like "output voltage, input voltage, wattage" to be shown in the product listing. I modified our products table to include the fields products_vout, products_vin, and products_wattage. I can display this on our product details page very easily...but I need to add these items as columns in the product listing (next to the model name, image, buy now, etc.). I've been working on this for 2 days now without much progress. I added the fields to the mysql queries (/catalog/index.php) and added the new field in the arrays (catalog/index.php, catalog/includes/modules/product_listing.php) and defined the TABLE_HEADER_VOUT information (/includes/languages/english/index.php).

 

Unfortunately, the changes I've made were somewhat stabs in the dark. I have a better understanding than when I began...but I don't understand where it is defined whether or not a column is to be included in the product listing.

 

If anyone has ANY insight into what I am doing wrong / a better approach, please help me.

 

Thank you,

I found what I was missing...just one little step

 

In the "configuration" table in the database, there has to be a row that corresponds to each product_listing column.

 

It now displays, and can also be sorted by that field :-)

I also need to add custom fields to my product(s). I was wondering if you could give me a few hints on how to do this or let me know where you found how to do this.

 

Thanks.
