Top Categories list under Product list

[ivanc]

Hi!

I am trying to add a top categories list (the same as it appears on main page centerb) under product listing.
I believe it will make navigating my site much easier because I don't use sideboxes at all, so there isn't a categories list on any side.


I have tried adding the following code just before the code for featured, specials, etc. centerboxes:

1. added following code from tpl_index_categories.php to tpl_index_product_list.php

<div class="centerColumn" id="indexCategories">
<div id="indexCategoriesMainContent" class="content"><?php
/**
 * require the html_define for the index/categories page
 */
  include($define_page);
?></div>

<?php
if (PRODUCT_LIST_CATEGORIES_IMAGE_STATUS_TOP == 'true') {
// categories_image
  if ($categories_image = zen_get_categories_image($current_category_id)) {
?>
<div id="categoryImgListing" class="categoryImg"><?php echo zen_image(DIR_WS_IMAGES . $categories_image, '', SUBCATEGORY_IMAGE_TOP_WIDTH, SUBCATEGORY_IMAGE_TOP_HEIGHT); ?></div>
<?php
  }
} // categories_image
?>

<?php
// categories_description
    if ($current_categories_description != '') {
?>
<div id="categoryDescription" class="catDescContent"><?php echo $current_categories_description;  ?></div>
<?php } // categories_description ?>
<!-- BOF: Display grid of available sub-categories, if any -->
<?php
  if (PRODUCT_LIST_CATEGORY_ROW_STATUS == 0) {
    // do nothing
  } else {
    // display subcategories
/**
 * require the code to display the sub-categories-grid, if any exist
 */
   require($template->get_template_dir('tpl_modules_category_row.php',DIR_WS_TEMPLATE, $current_page_base,'templates'). '/tpl_modules_category_row.php');
  }
?>
</div>
<!-- EOF: Display grid of available sub-categories -->

2. added following code I found on the forum to tpl_index_product_list.php

<?php
$cat_id=0;
 
    $categories_query = "SELECT c.categories_id, cd.categories_name, c.categories_image, c.parent_id
                          FROM   " . TABLE_CATEGORIES . " c, " . TABLE_CATEGORIES_DESCRIPTION . " cd
                          WHERE      c.parent_id = :parentID
                          AND        c.categories_id = cd.categories_id
                          AND        cd.language_id = :languagesID
                          AND        c.categories_status= '1'
                          ORDER BY   sort_order, cd.categories_name";
  
    $categories_query = $db->bindVars($categories_query, ':parentID', $cat_id, 'integer');
    $categories_query = $db->bindVars($categories_query, ':languagesID', $_SESSION['languages_id'], 'integer');
    $categories = $db->Execute($categories_query);
    $number_of_categories = $categories->RecordCount();
  
 require($template->get_template_dir('tpl_modules_category_row.php',DIR_WS_TEMPLATE, $current_page_base,'templates'). '/tpl_modules_category_row.php');
?>

3. tried also with these two lines

<?php require($template->get_template_dir('tpl_modules_category_row.php',DIR_WS_TEMPLATE, $current_page_base,'templates'). '/tpl_modules_category_row.php'); ?>

<?php require($template->get_template_dir('tpl_index_categories.php',DIR_WS_TEMPLATE, $current_page_base,'templates'). '/tpl_index_categories.php'); ?>

And neither works!
The product listing looks and works normal, completely ignoring any of my attempts.

I am sure there is a very simple solution to this issue, but I can't seem to find it.

Can anyone help?

Thanks!

Is there a reason you don't want to use the categories-tabs menu bar in the header? You can even add a simple test to it to hide it on the homepage if you don't need it there. Seeing your site live will help us make appropriate suggestions.

Yes, there are two! :)

1. my main page top categories list is heavily modified and I would like to use it if it's possible
2. categories-tabs don't fit into my current design. I could make it work but that would require a significant redesign. Simply adding the existing categories under the product list is much simpler and quicker (well, at least - should be).

Thank your extremely fast reply!

Thank your extremely fast reply!

Thank *you for* your extremely fast reply! :)

You don't want this bit in your product listing page, as $define_page will not be set for a product page. The include may not cause an error, but it will not do anything you want.

<div id="indexCategoriesMainContent" class="content"><?php
/**
 * require the html_define for the index/categories page
 */
  include($define_page);
?></div>

In what order did you add the code snippets to the file? The sql query must be run before output files are called, or there will be no content to output.

[gjh42]

Looking closer, you don't want any of your first block of code. The second block with the sql query will probably get the data (I haven't checked it thoroughly). You also don't want tpl_index_categories.php as that outputs a whole page content. You do want tpl_modules_category_row.php after the sql query is run and $categories is populated.

You don't need
$number_of_categories = $categories->RecordCount(); as a similar variable is set by category_row.php (which is called by tpl_modules_category_row.php).

[ivanc]

Sorry, didn't see your second post before replying, will check now!

[gjh42]

If you are still not getting results, you might try adding debug code, say after

    $categories = $db->Execute($categories_query); 

like

echo ' $categories populated: ' . var_dump($categories);

No luck, anything I try is completely ignored.

I am posting my complete tpl_index_product_list.php including the changes you suggested:

[gjh42]

You have

<?php
$show_display_category = $db->Execute(SQL_SHOW_PRODUCT_INFO_MISSING);

while (!$show_display_category->EOF) {
?>

<!-- INSERT CATEGORIES HERE TOP -->

Your new code is inside the while() loop, so will only be executed if there is anything in $show_display_category. Move your code either above or below that while() loop.
