PHP Warning: strpos() [<a href='function.strpos'>function.strpos</a>]: Empty delimiter help

[ken0306]

Hi,

I was trying to make my own side box for categories and manufactures filter box ( it is part of code that using on the index.php pages. ). I move the manufactures filter dropdown box and change to list link style on to a side box.

 

By combine the product specification add on, I manage to disable the manufactures filter, but still showing categories on the side box. It works as what I expect, but the script generate a error Empty delimiter. I know that is because of the return value can't be empty, but I don't know how to fix it. can some one help me out. here is my code.

 

 

<?php
if (isset($HTTP_GET_VARS['manufacturers_id']) == 0 ) {


  ?>


<?php
   if (isset($cPath) && strpos('_', $cPath)) {
// check to see if there are deeper categories within the current category
  $category_links = array_reverse($cPath_array);
  for($i=0, $n=sizeof($category_links); $i<$n; $i++) {
    $categories_query = tep_db_query("select count(*) as total from " . TABLE_CATEGORIES . " c, " . TABLE_CATEGORIES_DESCRIPTION . " cd where c.parent_id = '" . (int)$category_links[$i] . "' and c.categories_id = cd.categories_id and cd.language_id = '" . (int)$languages_id . "'");
    $categories = tep_db_fetch_array($categories_query);
    if ($categories['total'] < 1) {
	  // do nothing, go through the loop
    } else {
	  $categories_query = tep_db_query("select c.categories_id, cd.categories_name, c.categories_image, c.parent_id from " . TABLE_CATEGORIES . " c, " . TABLE_CATEGORIES_DESCRIPTION . " cd where c.parent_id = '" . (int)$category_links[$i] . "' and c.categories_id = cd.categories_id and cd.language_id = '" . (int)$languages_id . "' order by sort_order, cd.categories_name");
	  break; // we've found the deepest category the customer is in
    }
  }
   } else {
  $categories_query = tep_db_query("select c.categories_id, cd.categories_name, c.categories_image, c.parent_id from " . TABLE_CATEGORIES . " c, " . TABLE_CATEGORIES_DESCRIPTION .

strpos('_', $cPath)

Hi Jim

after I change

strpos('_', $cPath) to strpos($cPath, '_'), the categories still on my side box when I in the actual categories browsing products. So, how do I disable the categories box on the products categories products listing area?

thank you

[germ]

It's unsure to me what page you're on when you DON'T want the category box displayed.

 

Perhaps you can PM me a link to the page?
