Adding "Quantity Sold" to admin product listing


Guest

Recommended Posts

You can already see your top sellers in admin/stats_products_purchased.php, but while I'm in the admin catalog, adding / removing / browsing products, I would like to see how many of each item sold.

 

Here's how you do it (BACKING UP FIRST, of course):

 

- Step 1 -

in admin/categories.php, find the following line:

<td class="dataTableHeadingContent"><?php echo TABLE_HEADING_CATEGORIES_PRODUCTS; ?></td>

 

and add the following immediately afterwards:

<td class="dataTableHeadingContent" align="center">Quantity Sold</td>

 

 

- Step 2 -

add products_ordered to the appropriate queries. In other words, find:

 

if (isset($HTTP_GET_VARS['pID']) && empty($HTTP_POST_VARS)) {

$product_query = tep_db_query("select pd.products_name, pd.products_description, pd.products_url, p.products_id, p.products_quantity, p.products_model, p.products_image, p.products_price, p.products_weight, p.products_date_added, p.products_last_modified, date_format(p.products_date_available, '%Y-%m-%d') as products_date_available, p.products_status, p.products_tax_class_id, p.manufacturers_id from " . TABLE_PRODUCTS . " p, " . TABLE_PRODUCTS_DESCRIPTION . " pd where p.products_id = '" . (int)$HTTP_GET_VARS['pID'] . "' and p.products_id = pd.products_id and pd.language_id = '" . (int)$languages_id . "'");

 

and change to:

 

if (isset($HTTP_GET_VARS['pID']) && empty($HTTP_POST_VARS)) {

$product_query = tep_db_query("select pd.products_name, pd.products_description, pd.products_url, p.products_id, p.products_quantity, p.products_model, p.products_image, p.products_price, p.products_weight, p.products_date_added, p.products_last_modified, date_format(p.products_date_available, '%Y-%m-%d') as products_date_available, p.products_status, p.products_tax_class_id, p.manufacturers_id, products_ordered from " . TABLE_PRODUCTS . " p, " . TABLE_PRODUCTS_DESCRIPTION . " pd where p.products_id = '" . (int)$HTTP_GET_VARS['pID'] . "' and p.products_id = pd.products_id and pd.language_id = '" . (int)$languages_id . "'");

 

and find:

 

} elseif ($action == 'new_product_preview') {

if (tep_not_null($HTTP_POST_VARS)) {

$pInfo = new objectInfo($HTTP_POST_VARS);

$products_name = $HTTP_POST_VARS['products_name'];

$products_description = $HTTP_POST_VARS['products_description'];

$products_url = $HTTP_POST_VARS['products_url'];

} else {

$product_query = tep_db_query("select p.products_id, pd.language_id, pd.products_name, pd.products_description, pd.products_url, p.products_quantity, p.products_model, p.products_image, p.products_price, p.products_weight, p.products_date_added, p.products_last_modified, p.products_date_available, p.products_status, p.manufacturers_id from " . TABLE_PRODUCTS . " p, " . TABLE_PRODUCTS_DESCRIPTION . " pd where p.products_id = pd.products_id and p.products_id = '" . (int)$HTTP_GET_VARS['pID'] . "'");

$product = tep_db_fetch_array($product_query);

 

changing it to:

 

} elseif ($action == 'new_product_preview') {

if (tep_not_null($HTTP_POST_VARS)) {

$pInfo = new objectInfo($HTTP_POST_VARS);

$products_name = $HTTP_POST_VARS['products_name'];

$products_description = $HTTP_POST_VARS['products_description'];

$products_url = $HTTP_POST_VARS['products_url'];

} else {

$product_query = tep_db_query("select p.products_id, pd.language_id, pd.products_name, pd.products_description, pd.products_url, p.products_quantity, p.products_model, p.products_image, p.products_price, p.products_weight, p.products_date_added, p.products_last_modified, p.products_date_available, p.products_status, p.manufacturers_id, p.products_ordered from " . TABLE_PRODUCTS . " p, " . TABLE_PRODUCTS_DESCRIPTION . " pd where p.products_id = pd.products_id and p.products_id = '" . (int)$HTTP_GET_VARS['pID'] . "'");

$product = tep_db_fetch_array($product_query);

 

 

then find:

 

if (isset($HTTP_GET_VARS['search'])) {

$products_query = tep_db_query("select p.products_id, pd.products_name, p.products_quantity, p.products_image, p.products_price, p.products_date_added, p.products_last_modified, p.products_date_available, p.products_status, p2c.categories_id from " . TABLE_PRODUCTS . " p, " . TABLE_PRODUCTS_DESCRIPTION . " pd, " . TABLE_PRODUCTS_TO_CATEGORIES . " p2c where p.products_id = pd.products_id and pd.language_id = '" . (int)$languages_id . "' and p.products_id = p2c.products_id and pd.products_name like '%" . tep_db_input($search) . "%' order by pd.products_name");

} else {

$products_query = tep_db_query("select p.products_id, pd.products_name, p.products_quantity, p.products_image, p.products_price, p.products_date_added, p.products_last_modified, p.products_date_available, p.products_status from " . TABLE_PRODUCTS . " p, " . TABLE_PRODUCTS_DESCRIPTION . " pd, " . TABLE_PRODUCTS_TO_CATEGORIES . " p2c where p.products_id = pd.products_id and pd.language_id = '" . (int)$languages_id . "' and p.products_id = p2c.products_id and p2c.categories_id = '" . (int)$current_category_id . "' order by pd.products_name");

 

and change it to:

 

if (isset($HTTP_GET_VARS['search'])) {

$products_query = tep_db_query("select p.products_id, pd.products_name, p.products_quantity, p.products_image, p.products_price, p.products_date_added, p.products_last_modified, p.products_date_available, p.products_status, p2c.categories_id, products_ordered from " . TABLE_PRODUCTS . " p, " . TABLE_PRODUCTS_DESCRIPTION . " pd, " . TABLE_PRODUCTS_TO_CATEGORIES . " p2c where p.products_id = pd.products_id and pd.language_id = '" . (int)$languages_id . "' and p.products_id = p2c.products_id and pd.products_name like '%" . tep_db_input($search) . "%' order by pd.products_name");

} else {

$products_query = tep_db_query("select p.products_id, pd.products_name, p.products_quantity, p.products_image, p.products_price, p.products_date_added, p.products_last_modified, p.products_date_available, p.products_status, p.products_ordered from " . TABLE_PRODUCTS . " p, " . TABLE_PRODUCTS_DESCRIPTION . " pd, " . TABLE_PRODUCTS_TO_CATEGORIES . " p2c where p.products_id = pd.products_id and pd.language_id = '" . (int)$languages_id . "' and p.products_id = p2c.products_id and p2c.categories_id = '" . (int)$current_category_id . "' order by pd.products_name");

 

 

- Step 3 -

 

find:

 

<tr>

<td colspan="2"><?php echo tep_draw_separator('pixel_trans.gif', '1', '10'); ?></td>

</tr>

<tr>

<td class="main"><?php echo TEXT_PRODUCTS_QUANTITY; ?></td>

<td class="main"><?php echo tep_draw_separator('pixel_trans.gif', '24', '15') . ' ' . tep_draw_input_field('products_quantity', $pInfo->products_quantity); ?></td>

</tr>

<tr>

<td colspan="2"><?php echo tep_draw_separator('pixel_trans.gif', '1', '10'); ?></td>

</tr>

 

and add the following immediately afterwards:

 

<tr>

<td class="main">Quantity Ordered</td>

<td class="main"><?php echo tep_draw_separator('pixel_trans.gif', '24', '15') . ' ' . tep_draw_input_field('products_ordered', $pInfo->products_ordered); ?></td>

</tr>

 

<tr>

<td colspan="2"><?php echo tep_draw_separator('pixel_trans.gif', '1', '10'); ?></td>

</tr>

 

 

- Step 5 -

 

find:

 

<td class="dataTableContent"><?php echo '<a href="' . tep_href_link(FILENAME_CATEGORIES, 'cPath=' . $cPath . '&pID=' . $products['products_id'] . '&action=new_product_preview&read=only') . '">' . tep_image(DIR_WS_ICONS . 'preview.gif', ICON_PREVIEW) . '</a> ' . $products['products_name']; ?></td>

 

and add the following immediately afterwards:

 

<td class="dataTableContent" align="center"><?php echo $products['products_ordered']; ?>

 

 

I think that that was it!

NOTE: I know that there are more graceful ways to do this, and that I should have put the field names in the appropriate language file, but I only had a few minutes at the time. If someone *really* wants the proper coding way to do this, I can take the time to do it right. For now, here's the quick and dirty version.

 

NOTE2: This also adds this new field to the admin catalog, but when the line item displayed is a category or sub-category, no value will be displayed (unless someone figures out how sell a category rather than an item, I guess).

Hello, jcal.

 

I've just installed this contribution. I think this is great and very useful. The only problem is that the 'Quantity Ordered' in products_description is not modifiable and in admin/categories.php 'Quantity Sold' is not calculated right. Under 'Quantity Sold' column almost all of the numbers are negative: -2, -6, -8, 1, 0, -4. Why am I getting this? What did I do wrong?

 

Thanks.

Shouldn't happen. Those figures are pulled straight from the database. Please re-check the instructions, and if that doesn't work, feel free to PM me your login info and I'll have a look.
