模板求助！

请问下大虾们
                <!--{if !empty($_SBLOCK['hotnewspic'])}-->
                        <ul id="focus_pic">
                                <!--{eval $j = 0}-->
                                <!--{loop $_SBLOCK['hotnewspic'] $pkey $pvalue}-->
                                <!--{eval $pcurrent = ($j == 0 ? 'current' : 'normal');}-->
                                <li class="$pcurrent"><a href="$pvalue[url]"><img src="$pvalue['a_filepath']" alt="" /></a></li>
                                <!--{eval $j++}-->
                                <!--{/loop}-->
                        </ul>

请问下循环类似于这些{loop $_SBLOCK['hotnewspic'] $pkey $pvalue}数组的时候如何知道$pvalue[]数组的值可用！！比如$pvalue[url]，$pvalue['a_filepath']之类的。是数据库里面的字段吗？？

。。。。。。。。。。。。。

知道了

function block_spacenews($paramarr) {
        global $_SGLOBAL, $_SGET;
               
        $_SGLOBAL['attachsql'] = 'a.aid AS a_aid, a.type AS a_type, a.itemid AS a_itemid, a.uid AS a_uid, a.dateline AS a_dateline, a.filename AS a_filename, a.subject AS a_subject, a.attachtype AS a_attachtype, a.isimage AS a_isimage, a.size AS a_size, a.filepath AS a_filepath,a.thumbpath AS a_thumbpath, a.thumbpath AS a_thumbpath, a.downloads AS a_downloads';

。。。
。。
}
都在这边！

{eval secho($_SBLOCK['hotnewspic']);}  就可以了
