php篇一之上传文件

其实上传文件明白了道理也就很简单啦，小编当时学的时候也是一头雾水，搞了好多天才弄懂一点，好了废话少说吧，嘿嘿。首先运用的是tp3.2的框架，我这里前端名字是img.html

所以后台首先运用的是public function img()，然后选择上传的商品种类，再根据种类来选择固定的函数，而upload也就是确定所上传文件的格式还有保存路径等。最后再根据db_img上传到数据库。

首先是前端代码

<!DOCTYPE html>
<html>
<head>
 <title>后台管理</title>
 <link rel="stylesheet" type="text/css" href="__PUBLIC__/css/img.css"/>
</head>
<body>
  <header>
   <h1><img src="__PUBLIC__/image/admin_logo.png"/></h1>
   <ul class="rt_nav">
    <li><a href="{:U('Login/img')}" target="_blank" class="website_icon">站点首页</a></li>
    <li><a href="{:U('Login/order2')}" class="admin_icon">查看交易</a></li>
    <li><a href="{:U('Login/loginprocess')}" class="quit_icon">安全退出</a></li>
   </ul>
  </header>
<aside class="lt_aside_nav content mCustomScrollbar">
 <h2><a href="index.php">起始页</a></h2>
 <ul>
  <li>
   <dl>
    <dt>商品信息</dt>
    <!--当前链接则添加class:active-->
    <dd><a href="{:U('Login/img')}" >商品列表</a></dd>
    <dd><a href="{:U('Login/img')}" >商品分类</a></dd>
    <dd><a href="{:U('Login/img')}" >商品列表</a></dd>
    <dd><a href="{:U('Login/img')}" >商品信息</a></dd>
   </dl>
  </li>
  <li>
   <dl>
    <dt>订单信息</dt>
    <dd><a href="{:U('Login/order2')}">订单列表</a></dd>
    <dd><a href="{:U('Login/order3')}">用户购物车列表</a></dd>
   </dl>
  </li>
  <li>
   <p class="btm_infor">© 八号当铺  版权所有</p>
  </li>
 </ul>
</aside>

    <h2><strong style="color:grey;text-align: center;" >欢迎<span style="color:red">{$_SESSION['username']}</span>成为卖家</strong></h2>
     <section>
      <h2><strong style="color:grey;">卖家上传</strong></h2>
      <form method="POST" enctype="multipart/form-data">
      <ul class="ulColumn2">
       <li>
        <span class="item_name" style="120px;">商品名称：</span>
        <input type="text" class="textbox textbox_295" placeholder="文本信息提示..." name="f_name"/>
        <!-- <span class="errorTips">错误提示信息...</span> -->
       </li>
        <li>
        <span class="item_name" style="120px;">商品价格：</span>
        <input type="text" class="textbox textbox_295" placeholder="文本信息提示..." name="money" />
        <!-- <span class="errorTips">错误提示信息...</span> -->
       </li>
       <li>
        <span class="item_name" style="120px;">种类：</span>
        <select class="select" name="sel">
         <option value="close">服装</option>
         <option value="book">书刊</option>
         <option value="dian">电子</option>
        </select>
        <!-- <span class="errorTips">错误提示信息...</span> -->
       </li>
   <!--     <li>
        <span class="item_name" style="120px;">是否热销：</span>
        <label class="single_selection" ><input type="radio" value="y" />推荐</label>
        <label class="single_selection"><input type="radio" value="n" />不推荐</label>
       </li> -->
       <li>
        <span class="item_name" style="120px;">摘要：</span>
        <textarea placeholder="摘要信息" class="textarea" style="500px;height:100px;" name="message"></textarea>
       </li>
       <li>
        <span class="item_name" style="120px;">上传图片：</span>
        <label class="uploadImg">
         <input type="file" name="file[]" />
         <span>上传图片</span>
        </label>
       </li>
       <li>
        <span class="item_name" style="120px;"></span>
        <input type="submit" value="提交" class="link_btn"/>
       </li>
      </ul>
      </form>
     </section>
     
</body>
</html>


其次是后台（运用的是tp3.2框架）


// //后台添加图片

public function upload()
{
  //   //实例化上传类

  $upload->maxSize  = 3145728;

  $upload->rootPath = './';
  $info             = $upload->upload();
  $upload           = new Upload();
  
  if (!$info) {
    $this->error($upload->getError());
    // $this->error('shuangchuanshibai ',U('Login/loginss'),2);
  } else {
    //$this->success('上传成功');
    return $info;
  }
}

public function insert()
{
  $login  = D('logins');
  $result = $login->where(['username' => $_SESSIN['username']])->field()->find();
