ecshop添加相关文章功能方法

1、修改article.php，查询数据

//相关文章
    $sql_where = " where is_open=1 and article_id != '" .$_REQUEST[id]. "' ";
    $keywords=str_replace("，",  "," , $article['keywords']);
    $key_list=explode(",", $keywords);
    $key_id=0;
    $sql_or="";
    foreach ($key_list as $keyword)
    {
    	$sql_or .= $key_id ? " or " : "";
    	$sql_or .= " keywords like '%" . trim($keyword) . "%' ";
    	$key_id++;
    }
    $sql_or = " ( ". $sql_or ." ) ";
    $sql_where .= " and " . $sql_or ;
    $sql="sel ect article_id, cat_id, title, open_type, file_url from " . $ecs->table('article') . " $sql_where limit 0,10 ";
    $res_art_rel=$db->query($sql);
    while ( $row_art_rel = $db->fetchRow($res_art_rel) )
    {
    	$row_art_rel['url']=$row_art_rel['open_type'] != 1 ? build_uri('article', array('aid'=>$row_art_rel['article_id']), $row_art_rel['title']) : trim($row_art_rel['file_url']);
    	$art_rel_list[]=$row_art_rel;
    }
    $smarty->assign('art_rel_list', $art_rel_list);

2、创建/themes/themes_name/library/article_related.lbi

<div class="related-box">
	<div class="hd">
		<h3>相关文章</h3>
	</div>
	<ul>
		<!--{foreach from=$art_rel_list item=art_rel}-->
			<li><a href="{$art_rel.url}" target="_blank">{$art_rel.title}</a></li>
		<!--{/foreach}-->
	</ul>
</div>

3、article.dwt中调用上面的lbi

<!-- #BeginLibraryItem "/library/article_related.lbi" --><!-- #EndLibraryItem -->
