The layui framework implements file upload and TP3.2.3 (thinkPHP) performs background processing operations on uploaded files.

This article mainly introduces the implementation of file upload by layui framework and the background processing operation of uploaded files by TP3.2.3. It analyzes the related implementation skills of layui framework combined with thinkPHP for file upload and processing operations in the form of examples. Friends who need it can refer to it. Next

The example of this article describes the implementation of file upload by layui framework and the background processing operation of uploaded files by TP3.2.3. Share it with everyone for your reference, the details are as follows:

layui framework is version 1.0.9. .

First, the html page code is as follows:

<p class="layui-form-item" id="upload_file">
     <p class="layui-input-block" style="width: 300px;">
      <input type="hidden" id="img_url1" name="HeadImageUrl" value=""/>
      <p class="layui-upload-drag" id="uploadpic1" lay-verify="uploadpic1">
        <p class="layui-col-xs12 layui-col-md12">
          <img  class="layui-upload-img" id="demo1"  alt="The layui framework implements file upload and TP3.2.3 (thinkPHP) performs background processing operations on uploaded files." >
        </p>
        <p class="button-hide">
          <input type="file" name="banner_file_upload" id="banner_file_upload" class="layui-uplaod-file"  lay-type="file">
        </p>
      </p>
    </p>
</p>

The js code is as follows:

<script type="text/javascript" th:inline="javascript">
     layui.use(&#39;upload&#39;, function (){
       var upload = layui.upload;
       var url="/Public";
       upload({
         elem: &#39;#banner_file_upload&#39;,
         url: "/index.php/Admin/Product/upload",
         method: &#39;post&#39;,
         before: function(obj){
           console.log(&#39;文件上传中&#39;);
           layer.load();
         },
         success: function (msg) {
           console.log(msg);
           if(msg.msg=="success"){
             layer.closeAll(&#39;loading&#39;);
             layer.msg("上传成功");
             $("#img_url1").attr("value", msg.src);
           }else if(msg.msg=="error"){
             layer.closeAll(&#39;loading&#39;);
             layer.msg(msg.code);
           }
         },
         error:function (data) {
           layer.msg("上传失败");
           console.log(data);
         }
       });
     });
</script>

The next method of receiving the value in the php background:

#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);
}
