高手们来改下代码看看？

把SWF上传插件去掉改成：点击头像选择文件完成上传或点保存好完成上传
PHP后端：
public function avatar(){
$uid = get_cookie('uid');
$user = M('bering')->find($uid);
if (!$user) {
$this->error('请重新登录',U(MODULE_NAME.'/Public/login'));
}
if (IS_POST) {
$path = I('path', '', 'trim');
$data['face'] = $path;
$data['id'] = $uid;
if (empty($data['face'])) {
$this->error('请上传图片！');
}
if (M('bering')->save($data) !== false) {
$this->success('保存成功',U('bering/avatar'));
//$this->redirect('bering/avatar');
}else{
$this->error('保存失败！');
}
exit();
}
$this->assign('user', $user);
$this->assign('uid', $uid);
$this->assign('title', '头像设置');
$this->display();
}
public function saveavater(){
$uid = intval(get_cookie('uid'));
if (!$uid) {
$this->error('请重新登录',U('Public/login'));
}
$rs = array();
//上传切头像
$input = file_get_contents('php://input');
$data = explode('--------------------', $input);
$url = './uploads/avatar';
$file = '/'.$uid.'.jpg';
if (!file_exists($url)){
mkdir($url);
}
@file_put_contents($url.$file, $data[0]);
$rs['status'] = $url.$file;
$this->ajaxReturn($rs);
}
html_js前端：
<div class="picmain">
<div class="bering_main">
<div class="setting" id="avatar_main">
<div class="form">
<form method="post" enctype="multipart/form-data" id="upForm" action="{:U('bering/avatar')}">
