[hatimad]

Hello,

 

can anyone please explain to me why this code doesnt show sub-category when there is product in main category?

 

it shows subcategories otherwise

 

can it be modified to show subcategory even when there is products in main category

 

thank you

 

<?php

function show_subcategories($counter) 

{

global $fooa, $subcategories_string, $id, $HTTP_GET_VARS;

$cPath_new = 'cPath=' . $fooa[$counter]['path'];



$subcategories_string .= '<a href="';

$subcategories_string .= tep_href_link(FILENAME_DEFAULT, $cPath_new);

$subcategories_string .= '"  class="headerNavigation">';



// display category name

$subcategories_string .= $fooa[$counter]['name'];



$subcategories_string .= '</a> ';



if ($fooa[$counter]['next_id']) {

       $subcategories_string .= '<br>';

 show_subcategories($fooa[$counter]['next_id']);

}else{

 $subcategories_string .= ' ';

}

}

?>



<?php

if ($cPath) {

 $subcategories_string = '';

 $new_path = '';

 $id = split('_', $cPath);

 reset($id);

 while (list($key, $value) = each($id)) {

	 unset($prev_id);

	 unset($first_id);

	 $subcategories_query = tep_db_query("select c.categories_id, cd.categories_name, c.parent_id from " . TABLE_CATEGORIES . " c, " . TABLE_CATEGORIES_DESCRIPTION . " cd where c.parent_id = '" . $value . "' and c.categories_id = cd.categories_id and cd.language_id='" . $languages_id ."' order by sort_order, cd.categories_name");

	 $subcategory_check = tep_db_num_rows($subcategories_query);

	 if ($subcategory_check > 0) {

   $new_path .= $value;

   while ($row = tep_db_fetch_array($subcategories_query)) {

  	 $fooa[$row['categories_id']] = array(

     'name' => $row['categories_name'],

     'parent' => $row['parent_id'],

     'level' => $key+1,

     'path' => $new_path . '_' . $row['categories_id'],

     'next_id' => false

  	 );

  	 if (isset($prev_id)) {

     $fooa[$prev_id]['next_id'] = $row['categories_id'];

  	 }



  	 $prev_id = $row['categories_id'];

  	 

  	 if (!isset($first_id)) {

     $first_id = $row['categories_id'];

  	 }



  	 $last_id = $row['categories_id'];

   }

   $fooa[$last_id]['next_id'] = $fooa[$value]['next_id'];

   $fooa[$value]['next_id'] = $first_id;

   $new_path .= '_';

	 } else {

   break;

	 }

 }

}



if ($id[0][0] != ''){

 show_subcategories($id[0][0]);



 echo $subcategories_string;

}else{

 echo " ";

}



?>

anyone?

Your problem has nothing to do with the code you posted. It has to do with the code in default.php which only allows you to show sub-categories if there are no products defined. It is a flaw in the program design in my opinion.

[hatimad]

thank you for your reply

 

i will have to find some other way then i guess

[hatimad]

i figured out, the problem was not in default.php

 

the problem was in

   if ($id[0][0] != ''){ 

     show_subcategories($id[0][0]);

 

this was only taking first caracter of category id

 

that is if category id was 2 it will show 2 and if category id was 24 it will still show 2

 

i changed it to

	if ($id[0] != ''){

 show_subcategories($id[0]);

 

and it works now and hopefully it wont create any complication

 

thanks
