引入文件
```html
<script src="pathto/layui/layui.js"></script>
<script src="/static/cropper/croppers.js"></script>  /* 这是建议目录，不用改他自己代码 */
```

编写元素
```html
<a class="btn" id="editimg">选择上传</a>

```
初始化组件方法
```javascript
function init_cropper(){
    layui.config({
        base: '/static/cropper/' //layui自定义layui组件目录
    }).use(['form','croppers'], function () {
        var $ = layui.jquery
            ,form = layui.form
            ,croppers = layui.croppers
            ,layer= layui.layer;

        //创建一个头像上传组件
        croppers.render({
            elem: '#editimg'
            ,saveW:150     //保存宽度
            ,saveH:150
            ,mark:1/1    //选取比例
            ,area:'900px'  //弹窗宽度
            ,url: "/admin/x_file/upload_cimg"  //图片上传接口返回和（layui 的upload 模块）返回的JOSN一样
            ,done: function(url){ //上传完毕回调
                $("input[name=avatar]").val(url);
                $("#img-avatar").attr('src',url);
            }
        });

    });
}
init_cropper();

```

PHP端代码

```php

<?php
public function upload_cimg(){
        //获取文件对象
        $file = $this->request->file('file');
        //验证并上传
        $info = $file->validate(['size'=>'5242880','ext'=>'jpg,gif,png'])
            ->move(\Env::get('root_path') . 'public' . DIRECTORY_SEPARATOR . 'uploads'.DIRECTORY_SEPARATOR.'image');
        //判断是否成功
        if($info){
            $data['src'] = $this->request->domain(true).'/uploads/image/'.$info->getSaveName();
            $this->result($data,0,'上传成功');
        }else{
            $this->result('',200,$file->getError());
        }
    }
