Question

有人可以解释为什么这个插页不起作用吗？

if(isset($_POST['send'])){
    $query = 'INSERT INTO subsciber(data, ip, email) 
          VALUES(CURRENT_TIMESTAMP, "'.$_SERVER['REMOTE_ADDR'].'", "'.$_POST['email'].'")';
    $result =  @mysqli_query($dbc, $query);
}

表单代码如下所示：

<div class="row">
     <div class="col-md-4 col-md-offset-4 col-sm6-6 col-sm-offset-3 ">
         <form class="form-inline" role="form" method="post">
            <div class="form-group">
                <label class="sr-only" for="exampleInputEmail2">Email address</label>
                <input name='email' id="email" type="email" class="form-control transparent" placeholder="Your email here...">
            </div>
            <button type="submit" name='send' value='send' class="btn btn-danger btn-fill">Notify Me</button>
        </form>
    </div>
</div>

Answer 1

您应该包含mysqli error function以查看错误

    if(isset($_POST['send'])){
        $query = 'INSERT INTO subsciber(data, ip, email) 
              VALUES(CURRENT_TIMESTAMP, "'.$_SERVER['REMOTE_ADDR'].'", "'.$_POST['email'].'")';
//echo $query; to see query output
        $result =  mysqli_query($dbc, $query) or die(mysqli_error($dbc));
    }

同样data是mysqli keyword所以请在此处使用backtick

 $query = 'INSERT INTO subsciber(`data`, ip, email) 
                  VALUES(CURRENT_TIMESTAMP, "'.$_SERVER['REMOTE_ADDR'].'", "'.$_POST['email'].'")';

Answer 2

您的表单没有操作属性：

这样做：

<form action="the url to your PHP script">

Answer 3

替换

@mysqli_query($dbc, $query);

与

mysqli_query($dbc, $query);

Answer 4

而不是单引号，您可以使用doublequotation

试试这个

if(isset($_POST["send"])) {
    .....
}

无法将表单中的数据插入到mysql中
