易企cms默认版本能获取指定分类的所有产品,但是不能获取指定的个数,为了能够获取指定的个数,我找到了GetProductList方法进行了改进:
1.找到根目录下的include/product.class.php文件搜索关键字"GetProductList"将GetProductList方法替换为如下代码,
function GetProductList($cid,$skip=0,$take=10,$orderby="adddate desc",$all=false) { global $yiqi_db; $categorydata = new Category(); $exist = $categorydata->ExistCategory($cid); if($exist == 1) { $cids = array($cid); $cids = array_merge($cids,$categorydata->GetSubCategoryIDs($cid)); $cids = implode(‘,‘, $cids); if($all) { return $yiqi_db->get_results(CheckSql("select * from yiqi_product where cid in ($cids) order by $orderby limit $skip,$take ")); } else { return $yiqi_db->get_results(CheckSql(sprintf("select * from yiqi_product where cid in ($cids) and adddate <= ‘%s‘ order by $orderby limit $skip,$take",date("Y-m-d H:i:s")))); } } else { if($all) { return $yiqi_db->get_results(CheckSql("select * from yiqi_product order by $orderby")); } else { return $yiqi_db->get_results(CheckSql(sprintf("select * from yiqi_product where adddate <= ‘%s‘ order by $orderby",date("Y-m-d H:i:s")))); } } }
2.模板文件中如何调用:
{assign var="productlist" value=$productdata->GetProductList(3,0,5,"adddate desc")} {foreach from=$productlist item=subcateinfo} <li> <a href="{formaturl type="product" siteurl=$siteurl name=$subcateinfo->filename}">{$subcateinfo->name}</a> </li> {/foreach}
GetProductList(3,0,5,"adddate desc")参数说明:GetProductList(分类id,跳跃个数,输出个数,"adddate desc")注:所有的标签函数都是可以修改的!
