layui框架实现文件上传及TP3.2.3(thinkPHP)对上传文件进行后台处理操作示例


            本文实例讲述了layui框架实现文件上传及TP3.2.3对上传文件进行后台处理操作。分享给大家供大家参考，具体如下：

layui框架是1.0.9版本。。

首先html页面代码如下：





<div class="layui-form-item" id="upload_file">

     <div class="layui-input-block" style="width: 300px;">

      <input type="hidden" id="img_url1" name="HeadImageUrl" value=""/>

      <div class="layui-upload-drag" id="uploadpic1" lay-verify="uploadpic1">

        <div class="layui-col-xs12 layui-col-md12">

          <img class="layui-upload-img" id="demo1" >

        </div>

        <div class="button-hide">

          <input type="file" name="banner_file_upload" id="banner_file_upload" class="layui-uplaod-file"  lay-type="file">

        </div>

      </div>

    </div>

</div>







js代码如下：





<script type="text/javascript" th:inline="javascript">

     layui.use('upload', function (){

       var upload = layui.upload;

       var url="__PUBLIC__";

       upload({

         elem: '#banner_file_upload',

         url: "/index.php/Admin/Product/upload",

         method: 'post',

         before: function(obj){

           console.log('文件上传中');

           layer.load();

         },

         success: function (msg) {

           console.log(msg);

           if(msg.msg=="success"){

             layer.closeAll('loading');

             layer.msg("上传成功");

             $("#img_url1").attr("value", msg.src);

           }else if(msg.msg=="error"){

             layer.closeAll('loading');

             layer.msg(msg.code);

           }

         },

         error:function (data) {

           layer.msg("上传失败");

           console.log(data);

         }

       });

     });

</script>







接下来的php后台接值的方法：





#上传文件方法

public function upload(){

    $res=array(

     'code'=>1,

     'msg'=>'no sorry',

      'data'=>array(

        'src'=>'',

      )

    );

    #图片存放路径

    $directory = C('UPLOAD_PATH')."/Public/docment/";

    #判断目录是否存在 不存在则创建

    if(!(is_dir($directory))){

      $this->directory($directory);

    }

    #获取数据库最后一条id 当做文件名称

    $product_last_id=D('ApiProduct')->getLastId();

    $savename="ApiProduct_".time().'_'.($product_last_id['id']+1);

    $upload = new \Think\Upload();

    $upload->maxSize = 0;

    $upload->exts = array('doc','docx','xls','xlsx','pdf','txt');

    $upload->rootPath = $directory;

    $upload->saveName="$savename";

    $upload->savePath = '';

    $info = $upload->uploadOne($_FILES['banner_file_upload']);

    if(!$info){

      $res['code']=$upload->getError();

      $res['msg']='error';

    }else{

      $res['code']=0;

      $res['msg']='success';

      $res['src']="/Public/docment/".$savename.".".$info['ext'];

    }

   echo json_encode($res);die;

}

/**

* 递归创建文件

* @author erwa<erwa@qingjinju.net>

*/

public function directory($dir){

    return is_dir ( $dir ) or directory(dirname( $dir )) and mkdir ( $dir , 0777);

}
