上传自动填充文本款的问题

[foooy]

if (move_uploaded_file($tmp_name, $up_address . $fname)) {
$small_img=$lstname.'_xiao.'.$ftype;
echo "<script type=\"text/javascript\" src=\"../images/ajax.js\"></script>";
echo "<script type=\"text/javascript\">";
echo "post_filename('$fname','$small_img');";
echo "</script>";
echo "<script language=javascript>alert('上传成功');</script>";
luesuotu($up_address . $fname, $up_address, $lstname, $ftype); -------- 加上这句，就无法自动填充文本框图片已经生成
}

function luesuotu($imgs,$file,$name,$type) {
$newwidth = 50; //新图片宽度
$newheight = 50; //新图片高度
@ header('Content-type: image/jpeg'); //设置类型
$newim = imagecreatetruecolor($newwidth, $newheight); //生成一个空白背景
if (getimagesize($imgs)) {
$img = getimagesize($imgs);
list ($width, $height) = $img;
switch ($img[2]) {
case 1 :
$imlst = imagecreatefromgif($imgs);
break;
case 2 :
$imlst = imagecreatefromjpeg($imgs);
break;
case 3 :
$imlst = imagecreatefrompng($imgs);
break;
}
//生成略缩图
imagecopyresized($newim, $imlst, 0, 0, 0, 0, $newwidth, $newheight, $width, $height);
$newname=$name.'_xiao.'.$type;
imagejpeg($newim, $file.'/'.$newname);
} else {
echo "<script language=\"\">alert('无法读取原图片!');</script>";
}
}

header前不要有输出

if (move_uploaded_file($tmp_name, $up_address . $fname)) {
luesuotu($up_address . $fname, $up_address, $lstname, $ftype);
$small_img=$lstname.'_xiao.'.$ftype;
echo "<script type=\"text/javascript\" src=\"../images/ajax.js\"></script>";
echo "<script type=\"text/javascript\">";
echo "post_filename('$fname','$small_img');";
echo "</script>";
echo "<script language=javascript>alert('上传成功');</script>";
}
