Introduction

When browsing the categories the letter 'n' seems to appears all by itself in inappropriate locations on the page. The most common locations for this to happen is in the catalog/index.php.

Cause

Display shows the 'n' character in index page when categories are selected.

You have edited the index.php using the online file manager which has removed the \ backslashes from the code, this is a known issue with using the file manager to edit files, it is better to use an ftp program such as ws_ftp to download the file and edit it locally then ftp back to the server.

Solution

Using a normal file editor (i.e. NOT the online file manager), edit the same file that you'd previously edited with the file manager. catalog/index.php seems to be the most commonly edited file with this problem. Change all of the instances of "n"; to "\n"; . "n" is the code for a newline and is the letter n.

The most common occurences are as follows:

In catalog/index.php around line 104 look for this code:




while ($categories = tep_db_fetch_array($categories_query)) { 

      $rows++; 

      $cPath_new = tep_get_path($categories['categories_id']); 

      $width = (int)(100 / MAX_DISPLAY_CATEGORIES_PER_ROW) . '%'; 

      echo '                <td align="center" class="smallText" width="' . $width . '" valign="top"><a href="' . tep_href_link(FILENAME_DEFAULT, $cPath_new) . '">' . tep_image(DIR_WS_IMAGES . $categories['categories_image'], $categories['categories_name'], SUBCATEGORY_IMAGE_WIDTH, SUBCATEGORY_IMAGE_HEIGHT) . '<br>' . $categories['categories_name'] . '</a></td>' . "n"; 

      if ((($rows / MAX_DISPLAY_CATEGORIES_PER_ROW) == floor($rows / MAX_DISPLAY_CATEGORIES_PER_ROW)) && ($rows != $number_of_categories)) { 

        echo '              </tr>' . "n"; 

        echo '              <tr>' . "n"; 

      } 

    }

Change To:




while ($categories = tep_db_fetch_array($categories_query)) { 

      $rows++; 

      $cPath_new = tep_get_path($categories['categories_id']); 

      $width = (int)(100 / MAX_DISPLAY_CATEGORIES_PER_ROW) . '%'; 

      echo '                <td align="center" class="smallText" width="' . $width . '" valign="top"><a href="' . tep_href_link(FILENAME_DEFAULT, $cPath_new) . '">' . tep_image(DIR_WS_IMAGES . $categories['categories_image'], $categories['categories_name'], SUBCATEGORY_IMAGE_WIDTH, SUBCATEGORY_IMAGE_HEIGHT) . '<br>' . $categories['categories_name'] . '</a></td>' . "\n"; 

      if ((($rows / MAX_DISPLAY_CATEGORIES_PER_ROW) == floor($rows / MAX_DISPLAY_CATEGORIES_PER_ROW)) && ($rows != $number_of_categories)) { 

        echo '              </tr>' . "\n"; 

        echo '              <tr>' . "\n"; 

      } 

    }

In catalog/index.php around line #252 look for this code:




while ($filterlist = tep_db_fetch_array($filterlist_query)) { 

          $options[] = array('id' => $filterlist['id'], 'text' => $filterlist['name']); 

        } 

        echo tep_draw_pull_down_menu('filter_id', $options, (isset($HTTP_GET_VARS['filter_id']) ? $HTTP_GET_VARS['filter_id'] : ''), 'onchange="this.form.submit()"'); 

        echo '</form></td>' . "n"; 

      } 

    }

Change To:




while ($filterlist = tep_db_fetch_array($filterlist_query)) { 

          $options[] = array('id' => $filterlist['id'], 'text' => $filterlist['name']); 

        } 

        echo tep_draw_pull_down_menu('filter_id', $options, (isset($HTTP_GET_VARS['filter_id']) ? $HTTP_GET_VARS['filter_id'] : ''), 'onchange="this.form.submit()"'); 

        echo '</form></td>' . "\n"; 

      } 

    }

Line numbers will depend on how you've customized the file, but these are the general areas.

This issue will be corrected in the MS-3 release of osCommerce
