thinkphp结合layui上传视频

JS示例：

<script type="text/javascript">
layui.use(['form', 'layedit','element', 'laydate','upload'], function(){
    var form = layui.form;
    var layer = layui.layer;
    var layedit = layui.layedit;
    var laydate = layui.laysdate;
    // 上传
    var upload = layui.upload;
    var uploadInst1 = upload.render({
    elem: '#uploadImgBut1', //绑定元素
    url: "{:U('Admin/Upload/uploadmedia')}",//上传接口
    accept: 'video',
    done: function(res){
        if(res['state'] ==1){
            layer.msg(res['message']);
            $("#uploadImg1").attr('src',res['path']).show();
            $("input#uploadImgSrc1").val(res['path']); 
        };
    }
    }); 
});
</script>

PHP示例：

public function uploadmedia(){      
    $upload = new \Think\Upload();// 实例化上传类
    $mediaSize = intval(CP('MEDIASIZE'));
    $mediaType = CP('MEDIATYPE');
    $mediaSize = !empty($mediaSize) ? $mediaSize : 3145728;
    $mediaType = !empty($mediaType) ? explode(',',$mediaType) : array('mp3','mp4');
    $upload->maxSize   =     $mediaSize;// 设置附件上传大小
    $upload->exts      =     $mediaType;// 设置附件上传类型 
    $upload->rootPath  =     "./Uploads/Video/"; // 设置附件上传根目录
    $upload->savePath  =     ''; // 设置附件上传（子）目录
    $dataArr = array();
    $dataArr['code'] = 1;
    $dataArr['msg'] = '上传成功';
    $dataArr['data']['src'] = "";
    $dataArr['data']['title'] = "错误";
    // 上传文件 
    $info = $upload->upload();
    if(!$info){
        $dataArr['code'] = 0;
        $dataArr['msg'] = '上传失败';
    };
    $path = "/Upload/Video/".$info['file']['savepath'].$info['file']['savename'];
    $dataArr['data']['src'] = $path;
    $dataArr['data']['title'] = "成功";
    exit(json_encode($dataArr));
}
