帝国CMS上传图片并自动生成缩图教程

修改字段设置处理函数名称，后台字段函数设置：user_TranImgAuto##170,120     (说明：后台的参数170表示缩图宽度,120为缩图高度)
上传图片字段显示HTML代码：<input type=file name=titlepicimgrs size=45>   (说明：变量名用“字段名”+imgrs，即跟函数中的“$filetf”变量对应)
代码如下
以下函数复制到e/class/userfun.php文件内容里;
function user_TranImgAuto($mid,$f,$isadd,$isq,$value,$cs){
global $empire,$dbtbpre,$public_r,$emod_r,$class_r,$tranpicturetype,$musername;
$filetf=$f.'imgrs';//变量名
if(!$_FILES[$filetf]['name'])
{
return '';
}
$classid=(int)$_POST['classid'];
$id=(int)$_POST['id'];
$filepass=(int)$_POST['filepass'];
$filetype=GetFiletype($_FILES[$filetf]['name']);
$pr=$empire->fetch1(select qaddtran,qaddtransize,qaddtranimgtype from {$dbtbpre}enewspublic limit 1);
if(!$pr['qaddtran'])
{
printerror(CloseQTranPic,,1);
}
if(!strstr($pr['qaddtranimgtype'],|.$filetype.|))
{
printerror(NotQTranFiletype,,1);
}
if($_FILES[$filetf]['size']>$pr['qaddtransize']*1024)
{
printerror(TooBigQTranFile,,1);
}
if(!strstr($tranpicturetype,','.$filetype.','))
{
printerror(NotQTranFiletype,,1);
}
$tfr=DoTranFile($_FILES[$filetf]['tmp_name'],$_FILES[$filetf]['name'],$_FILES[$filetf]['type'],$_FILES[$filetf]['size'],$classid);
if($tfr['tran'])
{
$csr=explode(',',$cs);
$maxwidth=$csr[0];
$maxheight=$csr[1];
$yname=$tfr['yname'];
$name=$tfr['name'];
include_once(ECMS_PATH.'e/class/gd.php');
//生成缩图
$filer=ResizeImage($yname,$name,$maxwidth,$maxheight,$public_r['spickill']);
DelFiletext($yname);
if($filer['file'])
{
//写入数据库
$type=1;
$filetime=date(Y-m-d H:i:s);
$filesize=@filesize($filer['file']);
$filename=GetFilename(str_replace(ECMS_PATH,'',$filer['file']));
$adduser='[Member]'.$musername;
$infoid=$isadd==1?0:$id;
$empire->query(insert into {$dbtbpre}enewsfile(filename,filesize,adduser,path,filetime,classid,no,type,id,cjid,fpath) values('$filename','$filesize','$adduser','$tfr[filepath]','$filetime','$classid','[.$f.].addslashes(RepPostStr($_POST[title])).','$type','$infoid','$filepass','$public_r[fpath]'););

if($ifval)

}
}
