Guide: How to add sorting for featured products

**Vladimir7** · 4 Jan 2008, 05:47 PM

Sorry if this is posted in the wrong forum, feel free to move it...
I didn't want to upload this as a contrib yet because I have never done one before, and have only been working with zen cart for a couple weeks.
Also I really suck at creating instructions/documentation
So if anyone wants to rewrite this, or make it a contrib, feel free to (but credit would be nice)

What this does:
Adds a sort field to featured products. It works like how you can sort regular categories and products.

Instructions
Like always, BACK UP your store and database before attempting.
I did this on a stock zen cart, but maybe I missed something or made a mistake as I have only worked with zen for a few weeks.

Step 1: Run this query on the database

PHP Code:


ALTER TABLE `featured` ADD `sort_order` INT( 11 ) NOT NULL DEFAULT '0' AFTER `featured_date_available` ;

Step 2: In /admin/includes/languages/featured.php
Add these 2 defines

PHP Code:


define('TABLE_HEADING_SORT_ORDER','Sort');
define('TEXT_FEATURED_SORT_ORDER', 'Sort Order:');

Step 3: In /admin/featured.php
At around line 44 in case 'insert' statement
After

PHP Code:


$expires_date = ((zen_db_prepare_input($_POST['end']) == '') ? '0001-01-01' : zen_date_raw($_POST['end']));

Add

PHP Code:


$sort_order = zen_db_prepare_input($_POST['sort_order']);

Change

PHP Code:


$db->Execute("insert into " . TABLE_FEATURED . "
                    (products_id, featured_date_added, expires_date, status, featured_date_available)
                    values ('" . (int)$products_id . "',
                            now(),
                            '" . zen_db_input($expires_date) . "', '1', '" . zen_db_input($featured_date_available) . "')");

To

PHP Code:


$db->Execute("insert into " . TABLE_FEATURED . "
                    (products_id, featured_date_added, expires_date, status, featured_date_available, sort_order)
                    values ('" . (int)$products_id . "',
                            now(),
                            '" . zen_db_input($expires_date) . "', '1', '" . zen_db_input($featured_date_available) . "', '" . zen_db_input($sort_order) . "')");

At around line 64 in case 'update' statement

After

PHP Code:


$expires_date = ((zen_db_prepare_input($_POST['end']) == '') ? '0001-01-01' : zen_date_raw($_POST['end']));

Add

PHP Code:


$sort_order = zen_db_prepare_input($_POST['sort_order']);

In the

PHP Code:


 $db->Execute("update " . TABLE_FEATURED . "
                      set featured_last_modified = now(),
                          expires_date = '" . zen_db_input($expires_date) . "',
                          featured_date_available = '" . zen_db_input($featured_date_available) . "',
                          sort_order = '" . zen_db_input($sort_order) . "'
                      where featured_id = '" . (int)$featured_id . "'");

add the sort_order field like it is shown in the statement

At around line 219

PHP Code:


 $product = $db->Execute("select p.products_id, pd.products_name, p.products_price, p.products_priced_by_attribute,
                                      f.expires_date, f.featured_date_available, f.sort_order

Add f.sort_order like shown

Around line 277
After

PHP Code:

****NOTE I dont know how to get this working with templates.
I am relatively new to zen cart, so couldn't figure out where the template folder whould go

change

                                  AND p.products_id = pd.products_id and pd.language_id = :languagesID order by f.sort_order ";

NOTE*** I got rid of the $order_by variable, because I didn't know if it effected anything else, so put it straight into the query

I think that should be it....
I haven't tested it with featured products side boxes because I don't use it
