PHP我这个代码为什么提交什么数据都插入到数据的内容都一样呢?

这是1.php

<code><?php $db = new PDO('mysql:host=localhost;dbname=t1', 'root', '',array(PDO::MYSQL_ATTR_INIT_COMMAND => "SET NAMES 'utf8'"));
 $rs = $db -> prepare("select * from `baidu`;");
 $rs -> execute();
 $list = $rs -> fetchAll(PDO::FETCH_ASSOC);
?>




<div id="content">
  <?php foreach($list as $v){
      echo $v['type'].'<br />';
      echo $v['name'].'<br>';
      echo $v['num'].'<br>';
      echo $v['site'].'<br>';
      echo $v['content'].'<br>';
    }
  ?>
</div>
<div id="div1">
      <form action="2.php" method="post">
          <div>
            <select name="select">
              <option>请选择</option>
              <option>111</option>
              <option>222</option>
              <option>333</option>
              <option>444</option>
            </select>
            <input type="text" id="ipt1" name="name">
            <input type="text" id="ipt2" name="num">
            <input type="text" id="ipt3" name="site">
          </div>
          <textarea id="txt1" name="content"></textarea><br>
          <button type="submit">发布</button>
      </form>
</div>

这是2.php

<code><?php $pdo=new PDO("mysql:host=localhost;dbname=t1","root","");
if($pdo->exec("INSERT INTO baidu(
type,
name,
num,
site,
content
)
VALUES ('{$_POST['select']}','{$_POST['name']}','{$_POST['num']}','{$_POST['site']}','{$_POST['content']}')"){
echo "<script>alert('发布成功');location='1.php';</script>";

既然你使用PDO, 那2.php 的插入逻辑改下:

<code>$sql = "INSERT INTO baidu(type,name,num,site,content) VALUES (:type,:name,:num,:site,:content)";

$stmt = $pdo->prepare($sql);

$stmt->execute(array(':type' => $_POST['type'], ':name' => ....));
</code>

额,其实我也是小白,'{$_POST['name']}' 这里面的name旁边的引号需不需要转义,因为外面已经有引号了,我没试过,会不会是这个问题

表单都没传值(value),提交之后打印出来看下数据是否正确
