Let's talk about the steps to modify the column alias called by Empire CMS

//替换变量
$bclassname=$class_r[$classid][classname];
$bname=$class_r[$classid][bname];
$br[classid]=$classid;
$bclassurl=sys_ReturnBqClassname($br,9);
$listtemp=str_replace("[!--bclassname--]",$bclassname,$listtemp);
$listtemp=str_replace("[!--bname--]",$bname,$listtemp);
$listtemp=str_replace("[!--bclassurl--]",$bclassurl,$listtemp);

$sql=$empire->query("select classid,classname,bname,islast,sonclass,tbname,intro,classimg from 
{$dbtbpre}enewsclass where bclassid='$classid' and showclass=0 order by myorder,classid".$limit);

//栏目名称
$listtemp=str_replace("[!--classname--]",$r[classname],$listtemp);
//栏目别名
$listtemp=str_replace("[!--bname--]",$r[bname],$listtemp);
//栏目id
$listtemp=str_replace("[!--classid--]",$r[classid],$listtemp);
