最近在做一个程序，需要用UploadFile函数上传图片，数据库能写入，但是图片总是上传不成功，查找众多资料后，终于找到原因，需要在form中加入 enctype="multipart/form-data"

前台模板文件：

<form id="store_form" method="post" enctype="multipart/form-data">

<span class="type-file-show"><img class="show_image" src="<?php echo TEMPLATES_PATH;?>/images/preview.png">
            <div class="type-file-preview"><img src="<?php echo SiteUrl.'/'.(ATTACH_PATH.DS.'ad'.DS.$output['store_array']['shopad']);?>" width="90" height="90"></div>
            </span>
          <span class="type-file-box"><input type='text' name='textfield' id='textfield1' class='type-file-text' /><input type='button' name='button' id='button1' value='' class='type-file-button' />
            <input name="shopad" type="file" class="type-file-file" id="shopad" size="30" hidefocus="true" nc_type="change_shopad">
            </span>

</form>

PHP处理代码：

if (chksubmit()){
   
   /**
    * 上传图片
    */
   $upload = new UploadFile();
   $upload->set('default_dir',ATTACH_PATH.'/ad');
   /**
    * 取店铺等级的审核
    */
   $model_grade = Model('store_grade');
   $grade_array = $model_grade->getOneGrade(intval($_POST['grade_id']));
   if (empty($grade_array)){
    showMessage($lang['please_input_store_level']);
   }
   /**
    * 上传店铺广告图片
    */
   if (!empty($_FILES['shopad']['name'])){
    $upload = new UploadFile();
    $upload->set('default_dir',ATTACH_PATH.'/ad');
    $result = $upload->upfile('shopad');
    if ($result){
     $_POST['shopad'] = $upload->file_name;
    }else {
     showMessage($upload->error,'','','error');
    }
   }
   /**

   $store_info = $model_store->shopStore(array('store_name'=>$update_array['store_name']));

   }else {

   }
