1.前端html程式碼

<div class="layui-form-item">
    <label class="layui-form-label">修改頭像</label>
    <div class="layui-input-inline uploadHeadImage">
        <div class="layui-upload-drag" id="headImg">
            <i class="layui-icon"></i>
            <p>點選上傳圖片，或將圖片拖拽到此處</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程式碼

<script>layui.use(['form', 'layer','upload',"element"],
    function() {
        $ = layui.jquery;
        var form = layui.form,
            upload = layui.upload,
            layer = layui.layer;
        //拖拽上傳
        var uploadInst = upload.render({
            elem: '#headImg'
            , url: '{:url("uploadImg")}'
            , size: 500
            , before: function (obj) {
                //預讀本地檔案示例，不支援ie8
                obj.preview(function (index, file, result) {
                    $('#demo1').attr('src', result); //圖片連結（base64）
                });
            }
            , done: function (res) {
                console.log(res);
                //如果上傳失敗
                if (res.code > 0) {
                    return layer.msg('上傳失敗');
                }
                var demoText = $('#demoText');
                // demoText.html('<span style="color: #8f8f8f;">上傳成功!!!</span>');
                $("#imagepath").val(res.image)
                layer.msg("上傳成功")
            }
            , error: function () {
                //演示失敗狀態，並實現重傳
                var demoText = $('#demoText');
                demoText.html('<span style="color: #FF5722;">上傳失敗</span> <a class="layui-btn layui-btn-mini demo-reload">重試</a>');
                demoText.find('.demo-reload').on('click', function () {
                    uploadInst.upload();
                });
            }
        });
        element.init();
});
 

3.後臺php程式碼

    // 圖片上傳
    public function uploadImg(){
        // 上傳程式碼
        $file = request()->file('file');
        // 上傳到本地伺服器
        $savename = \think\facade\Filesystem::disk('public')->putFile( 'goods', $file);
        $data['image'] = $savename;
        $data['code'] = 0;

        return json($data);
    }
