laravel + layui 图片上传

使用原生form表单提交必须使用

enctype="multipart/form-data"

<form action="./a.php" method="post" enctype="multipart/form-data">
    <input type="file" name="aa">EXCEL上传
    <input type="submit">
</form>

 

 

1.前端HTML代码

<div class="layui-form-item">
    <label class="layui-form-label">修改头像</label>
    <div class="layui-input-inline uploadHeadImage">
        <div class="layui-upload-drag" id="headImg">
            <i class="layui-icon"></i>
            <p>点击上传图片，或将图片拖拽到此处</p>
        </div>
    </div>
    <div class="layui-input-inline">
        <div class="layui-upload-list">
            <img class="layui-upload-img headImage" src="" id="demo1">
            <p id="demoText"></p>
        </div>
    </div>
</div>

2.前端js代码

<script>layui.use(['form', 'layer','upload',"element"],
    function() {
        $ = layui.jquery;
        var form = layui.form,
            upload = layui.upload,
            layer = layui.layer;
        //拖拽上传
        var uploadInst = upload.render({
            elem: '#headImg'
            , url: '{:url("uploadImg")}'
            , size: 500
            , before: function (obj) {
                //预读本地文件示例，不支持ie8
                obj.preview(function (index, file, result) {
                    $('#demo1').attr('src', result); //图片链接（base64）
                });
            }
            , done: function (res) {
                console.log(res);
                //如果上传失败
                if (res.code > 0) {
                    return layer.msg('上传失败');
                }
                var demoText = $('#demoText');
                // demoText.html('<span style="color: #8f8f8f;">上传成功!!!</span>');
                $("#imagepath").val(res.image)
                layer.msg("上传成功")
            }
            , error: function () {
                //演示失败状态，并实现重传
                var demoText = $('#demoText');
                demoText.html('<span style="color: #FF5722;">上传失败</span> <a class="layui-btn layui-btn-mini demo-reload">重试</a>');
                demoText.find('.demo-reload').on('click', function () {
                    uploadInst.upload();
                });
            }
        });
        element.init();
});

3.后台PHP代码

 $uid = Session::get("member_id");
            $extension = $request->file('file')->extension(); // 上传文件扩展名
            $time = time();
            $path = $request->file('file')->storeAs('avatars', "$time.$extension");//上传图片
            $url = "/uploads/".$path;
            DB::table("users")->where(['uid'=>$uid])->update(['users_img'=>$url]);
            return response()->json(['code'=>0,'img'=>$url]);

4.laravel 默认上传图片的地址没有默认在public里面 需要修改配置文件

4.1默认图片上传地址

 

 

此时的文件不能直接访问，修改配置文件

 

 再次上传

 

 

$extension = $request->file('avatar')->extension(); // 上传文件扩展名
$name = $request->file('avatar')->getClientOriginalName();// 获取原始文件名
