zencart价格筛选插件

1.首先，新建文件includes\modules\sideboxes\price_range.php

<?php
function zen_count_products_in_price($pfrom, $pto)
{
    global $db;
    if ((int)$pfrom >= 1) {    
        $products_query = "select count(*) as total
        from " . TABLE_PRODUCTS . " p, " . TABLE_PRODUCTS_TO_CATEGORIES . " p2c
        where p.products_id = p2c.products_id
        and p.products_price > " . $pfrom;
        if ($pto != \'∞\')
        {
            $products_query .= " and p.products_price <= ".$pto;
        }
        //echo $products_query . \'<br />\';
        $products = $db->Execute($products_query);
        $products_count = $products->fields[\'total\'];
    }
    return (int)$products_count;
}

$price_array = array();
$price_array[] = array(\'pfrom\'=>1,\'pto\'=>300,\'counts\'=>zen_count_products_in_price(1,300));
$price_array[] = array(\'pfrom\'=>301,\'pto\'=>500,\'counts\'=>zen_count_products_in_price(301,500));
$price_array[] = array(\'pfrom\'=>501,\'pto\'=>1000,\'counts\'=>zen_count_products_in_price(501,1000));
$price_array[] = array(\'pfrom\'=>1001,\'pto\'=>2000,\'counts\'=>zen_count_products_in_price(1001,2000));
$price_array[] = array(\'pfrom\'=>2001,\'pto\'=>3000,\'counts\'=>zen_count_products_in_price(2001,3000));
$price_array[] = array(\'pfrom\'=>3001,\'pto\'=>4000,\'counts\'=>zen_count_products_in_price(3001,4000));
$price_array[] = array(\'pfrom\'=>4001,\'pto\'=>5000,\'counts\'=>zen_count_products_in_price(4001,5000));
$price_array[] = array(\'pfrom\'=>5001,\'pto\'=>\'∞\',\'counts\'=>zen_count_products_in_price(5001,\'all\'));
$content = \'\';
$This_cPath = $cPath;
$content .= \'<div id="\' . str_replace(\'_\', \'-\', $box_id . \'Content\') . \'" class="sideBoxContent">\' . "\n";
$content .= \'<ul>\';
$price_array_count = count($price_array);
for($rr=0;$rr<$price_array_count;$rr++)
{
    $content .= \'<li><a\';
    if($price_array[$rr][\'pfrom\']==$_GET[\'pfrom\'] and $price_array[$rr][\'pto\']==$_GET[\'pto\'])
    {
        $content .= \' class="pricecurrent"\';
    }
    $content .= \' href="index.php?main_page=advanced_search_result&search_in_description=1\';
    if($_GET[\'categories_id\'])
    {
        echo \'&categories_id=\'.$This_cPath;
    }
    $content .= \'&inc_subcat=1&pfrom=\'.$price_array[$rr][\'pfrom\'].\'&pto=\'.$price_array[$rr][\'pto\'].\'" rel="nofollow">\'.$price_array[$rr][\'pfrom\'];
    if(!empty($price_array[$rr][\'pto\']))
    {
        $content .= \' - \'.$price_array[$rr][\'pto\'].$GLOBALS[\'currencies\']->currencies[$_SESSION[\'currency\']][\'symbol_left\'];
    }else{
        $content .= \'&nbsp;Up to...\';
    }
    $content .= \'</a><span>(\'.$price_array[$rr][\'counts\'].\')</span></li>\';
}
$content .= \'</ul>\';
$content .= \'</div>\';

$title =  \'Price Range\';
require($template->get_template_dir($column_box_default, DIR_WS_TEMPLATE, $current_page_base,\'common\') . \'/\' . $column_box_default);
?>

 

2.用css代码美化前台显示

#pricerange a{
padding-left:15px; 
line-height:27px; 
font-size:12px; 
color:#666; 
background:url("../images/pricea.gif") no-repeat scroll 0 2px transparent;
}
#pricerange a:hover, #pricerange a.pricecurrent { 
color:#0075e2;
text-decoration:none;
background:url("../images/priceahover.gif") no-repeat scroll 0 2px transparent;
}
#pricerange ul, #pricerange ul li{ 
padding:0; 
margin:0;
}
#pricerange ul li {
    border-bottom: 1px dashed #ccc;
    line-height: 23px;
    list-style-type: none;
    text-indent: 12px;
    font-size:12px;
}
#pricerange ul li span {
    color: #999999;
    display: inline;
    font: 10px Arial;
    padding-left:2px;
}
