Compare multiple products - support thread

[Design75]

Hi
Just wondered if anyone has seen the following and if there is a fix for it:

I just recently installed v1.02. Everything except a previous noted error regarding advance search worked ok. I managed to fix the advance search myself. However, looking through the cahe log I noticed the following:

PHP Warning: Invalid argument supplied for foreach() in /var/www/vhosts/*****************/httpdocs/catalog/ajax_compare.php on line 29

Has anybody else noticed this?

I found a website that gave an indication that the coding may be wrong on line 29. As I'm not a programmer, I am at a loss.

Below is an extract from the web site I found:

(Invalid argument supplied for foreach() can happen if you try to do a foreach on an variable that isn't an array. Maybe it is "supposed to" be an array, maybe you thought it was an array, but sorry -- it isn't.)

I have the same problem.

Copy the following define statements from index.php to advanced_search_result.php

// values for compare system
  define('COMPARE_DEFAULT', 'Compare');
  define('COMPARE_REMOVE', 'remove');
  define('COMPARE_COUNT_START', 'up to ');
  define('COMPARE_COUNT_END', ' items');

copy the following code from tpl_index_product_list.php to tpl_advanced_search_result_default.php

<div id="compareResult">
  <div class="back compareText"><b><?php echo COMPARE_DEFAULT; ?></b><br /><?php echo COMPARE_COUNT_START . COMPARE_VALUE_COUNT . COMPARE_COUNT_END; ?></div>
  <div id="compareProducts">
<?php
if (!empty($_SESSION['compare'])) {
  foreach ($_SESSION['compare'] as $value) {
    $product_comp_image = $db->Execute(
        "SELECT p.products_id, p.master_categories_id, pd.products_name, p.products_image
         FROM " . TABLE_PRODUCTS . " p
         LEFT JOIN " . TABLE_PRODUCTS_DESCRIPTION . " pd
         ON pd.products_id=p.products_id
         WHERE p.products_id='".$value."'");
         
    $comp_images .= '<div class="compareAdded"><br /><a href="' . zen_href_link(zen_get_info_page($product_comp_image->fields['products_id']), 'cPath=' . (zen_get_generated_category_path_rev($product_comp_image->fields['master_categories_id'])) . '&products_id=' . $product_comp_image->fields['products_id']) . '">' . $product_comp_image->fields['products_name'] . '</a><div>'.'<a onclick="javascript: compareNew('.$product_comp_image->fields['products_id'].', \'remove\')" alt="remove">'.COMPARE_REMOVE.'</a>'.'</div></div>';
  }
  echo '<div id="compareMainWrapper"><div class="compareAdded compareButton">'.'<a href="index.php?main_page=compare" alt="compare">'.'<span class="cssButton">'.COMPARE_DEFAULT.'</span></a></div>'.$comp_images.'</div>';
  echo '<br class="clearBoth" />';
}
?>
</div>
</div>

Now you will be able to add & compare products from the search result page.

Hope this helps!

Hey! Sorry I missed your reply. Yes the first part work which makes sense. I did the code copy to the advanced tpl file but it does not work.

My apologies. It does work. I just did not scroll down to the bottom where it appeared. It is dependent on where you put the code!

I put mine after

<h1 id="advSearchResultsDefaultHeading"><?php echo HEADING_TITLE; ?></h1>

Thanks again.

I have a fix for this issue but I'm unsure if it leaves open a security hole.

You only have to comment out one line within 'includes/init_includes/init_sanitize.php' at about line 34:

zen_redirect ( zen_href_link ( FILENAME_PAGE_NOT_FOUND, '', $request_type ) );

Not sure how to fix it but I'm nearly positive it has something to do with jQuery no conflict.

This is the javascript error I get when I click on one of the checkboxes.

Uncaught TypeError: Property '$' of object [object DOMWindow] is not a function

I tried to resolve with the many different no conflict solutions but none of them worked.

Has anyone updated this plugin for version 1.5? I tried to install it but the check boxes won't show up next to the products in the product listing.
