EmpireCMS retrieves database articles based on an ID.

Query the `news` table for articles using the provided article ID:

$id=(int)$_GET['id'];
$r=$empire->fetch1("select * from {$dbtbpre}ecms_news where id=$id");
$classid=(int)$r['classid'];

Fallback query code for determining whether a `classid` has been provided:

// print_r($_GET);die;
if(empty($_GET['classid'])){
    $id=(int)$_GET['id'];
    $r=$empire->fetch1("select * from {$dbtbpre}ecms_news where id=$id");
    $classid=(int)$r['classid'];
}else{
    $id=(int)$_GET['id'];
    $classid=(int)$_GET['classid'];
}

Comprehensive Code 2.0:

// print_r($_GET);die;
if(empty($_GET['classid'])){
    $id=(int)$_GET['id'];
    $r=$empire->fetch1("select * from {$dbtbpre}ecms_news where id=$id");
    if (empty($r['id'])) {
        printerror('此信息不存在','',1,0,1);
    }
    $classid=(int)$r['classid'];
}else{
    $id=(int)$_GET['id'];
    $classid=(int)$_GET['classid'];
}
