Dynamic Filter [Support Thread]

[Kevin205]

Overrides are:

The mod has the following overrides, which I have added.

includes/classes/split_page_results.php
includes/functions/functions_general.php
includes/modules/pages/advanced_search_result/header_php.php
includes/modules/pages/featured_products/header_php.php
includes/modules/pages/products_all/header_php.php
includes/modules/pages/products_new/header_php.php
includes/modules/pages/specials/header_php.php
includes/modules/pages/specials/main_template_vars.php

It also askes you to add a template override includes/index_filters/YOUR_TEMPLATE/default_filter.php

The only thing I have not done is to add

[B]$excludeParams[] = DYNAMIC_FILTER_PREFIX . 'Colour';[/B] 

to includes/init_includes/init_canonical.php file, Since I am getting a white page, am not even there yet.

Ok so first things first.

Do any of the files that have be overridden been modified by any of your other mods?

Secondly, starting to come back to me now. Pretty sure almost all if not all of the header files were out of date? Check the file version compared to the dynamic filter ones, I think I had to merge them.

Don't worry about cannonical, that doesn't do anything at this stage. All it will do is ensure that your canonical links in the source are correct when the filters are applied.

I removed the only one that did, which was Products Listing Sorter v1.1

Oh I have to look at that.

ps. where can I get DrByte's Code revision?

[philip937]

So you use the 1.5.1 file and change this function re written by DrByte
http://www.zen-cart.com/showthread.p...44#post1188244

That should be the only function in the file that is changed for dynamic filter and that version DrByte rewrote works fine for dynamic filter

[Kevin205]

OK then in:
(1) Code from the mod - Creating the error and the white page.

  function zen_get_all_get_params($exclude_array = '', $search_engine_safe = true) {

    if (!is_array($exclude_array)) $exclude_array = array();

    $get_url = '';
    if (is_array($_GET) && (sizeof($_GET) > 0)) {
      reset($_GET);
      while (list($key, $value) = each($_GET)) {
// bof dynamic filter 1 of 3
        if ( (!in_array($key, $exclude_array)) && (strlen($value) > 0 || is_array($value) && array_filter($value) ) && ($key != 'main_page') && ($key != zen_session_name()) && ($key != 'error') && ($key != 'x') && ($key != 'y') ) {
// eof dynamic filter 1 of 3
          if ( (SEARCH_ENGINE_FRIENDLY_URLS == 'true') && ($search_engine_safe == true) ) {
//    die ('here');
            $get_url .= $key . '/' . rawurlencode(stripslashes($value)) . '/';
          } else {
// bof dynamic filter 2 of 3
            if (is_array($value)) {
              foreach($value as $arr){
                $get_url .= zen_sanitize_string($key) . '[]=' . rawurlencode(stripslashes($arr)) . '&';
              }
            } else {
// eof dynamic filter 2 of 3
              $get_url .= zen_sanitize_string($key) . '=' . rawurlencode(stripslashes($value)) . '&';
// bof dynamic filter 3 of 3
            }
// eof dynamic filter 3 of 3
          }
        }
      }
    }
    while (strstr($get_url, '&&')) $get_url = str_replace('&&', '&', $get_url);
    while (strstr($get_url, '&&')) $get_url = str_replace('&&', '&', $get_url);

    return $get_url;
  } 

(2)DrBytes revision:

  function zen_get_all_get_params($exclude_array = array(), $search_engine_safe = true) {
    if (!is_array($exclude_array)) $exclude_array = array();
    $exclude_array = array_merge($exclude_array, array(zen_session_name(), 'main_page', 'error', 'x', 'y'));
    $get_url = '';
    if (is_array($_GET) && (sizeof($_GET) > 0)) {
      reset($_GET);
      while (list($key, $value) = each($_GET)) {
        if (!in_array($key, $exclude_array)) {
          if (!is_array($value)) {
            if (is_string($value) && strlen($value) > 0) {
              $get_url .= zen_sanitize_string($key) . '=' . rawurlencode(stripslashes($value)) . '&';
            }
          } else {
            foreach(array_filter($value) as $arr){
              $get_url .= zen_sanitize_string($key) . '[]=' . rawurlencode(stripslashes($arr)) . '&';
            }
          }
        }
      }
    }
    while (strstr($get_url, '&&')) $get_url = str_replace('&&', '&', $get_url);
    while (strstr($get_url, '&&')) $get_url = str_replace('&&', '&', $get_url);

    return $get_url;
  } 

(3)Code from my backup working site before Dynamic Filter

    function zen_get_all_get_params($exclude_array = '', $search_engine_safe = true) {

    if (!is_array($exclude_array)) $exclude_array = array();
    $exclude_array = array_merge($exclude_array, array(zen_session_name(), 'main_page', 'error', 'x', 'y'));
    $get_url = '';
    if (is_array($_GET) && (sizeof($_GET) > 0)) {
      reset($_GET);
      while (list($key, $value) = each($_GET)) {
        if (is_array($value) || in_array($key, $exclude_array)) continue;
        if (strlen($value) > 0) {
          $get_url .= zen_sanitize_string($key) . '=' . rawurlencode(stripslashes($value)) . '&';
        }
      }
    }
    while (strstr($get_url, '&&')) $get_url = str_replace('&&', '&', $get_url);
    while (strstr($get_url, '&&')) $get_url = str_replace('&&', '&', $get_url);

    return $get_url;
  } 

I just have to replace (3) with (2)?

[philip937]

Correct replace with (2) make sure you are doing this in a clean v1.5.1 functions general file

however I'm pretty sure that is not what is causing your error as I did not face the same thing. All this code change did was stopped some error log warnings.

I suspect that the problem is with other files that haven't merged properly.

You need to check the override files vs the version revisions of the 1.5.1 files they override. If they are older then they need to be merged. Will be going to bed very soon so won't be able to reply for a while. Just take it step by step one file at a time. The key is to ensure you are using the same files as version 1.5.1 uses and merge the changes dynamic filter makes.

On the plus side, I didn't find it hard to merge any of them apart from the functions general one to make it all good which DrByte kindly stepped in a did for us.
