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：

<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" >
        </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>

js代码如下：

<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>

接下来的php后台接值的方法：

#上传文件方法
public function upload(){
    $res=array(
     &#39;code&#39;=>1,
     &#39;msg&#39;=>&#39;no sorry&#39;,
      &#39;data&#39;=>array(
        &#39;src&#39;=>&#39;&#39;,
      )
    );
    #图片存放路径
    $directory = C(&#39;UPLOAD_PATH&#39;)."/Public/docment/";
    #判断目录是否存在 不存在则创建
    if(!(is_dir($directory))){
      $this->directory($directory);
    }
    #获取数据库最后一条id 当做文件名称
    $product_last_id=D(&#39;ApiProduct&#39;)->getLastId();
    $savename="ApiProduct_".time().&#39;_&#39;.($product_last_id[&#39;id&#39;]+1);
    $upload = new \Think\Upload();
    $upload->maxSize = 0;
    $upload->exts = array(&#39;doc&#39;,&#39;docx&#39;,&#39;xls&#39;,&#39;xlsx&#39;,&#39;pdf&#39;,&#39;txt&#39;);
    $upload->rootPath = $directory;
    $upload->saveName="$savename";
    $upload->savePath = &#39;&#39;;
    $info = $upload->uploadOne($_FILES[&#39;banner_file_upload&#39;]);
    if(!$info){
      $res[&#39;code&#39;]=$upload->getError();
      $res[&#39;msg&#39;]=&#39;error&#39;;
    }else{
      $res[&#39;code&#39;]=0;
      $res[&#39;msg&#39;]=&#39;success&#39;;
      $res[&#39;src&#39;]="/Public/docment/".$savename.".".$info[&#39;ext&#39;];
    }
   echo json_encode($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);
}
