Question

正如标题所说，我无法在MySQL中插入联系表单（使用Bootstrap）（我使用mysqli）。下面是我的PHP脚本：

<?php
    $conn = mysqli_connect('localhost', 'root', 'mypassword', 'mydbname');

    if (!$conn) {
     echo "Error: Unable to connect to MySQL." . PHP_EOL;
     echo "Debugging errno: " . mysqli_connect_errno() . PHP_EOL;
     echo "Debugging error: " . mysqli_connect_error() . PHP_EOL;
     exit;
    }

    if(isset($_POST['submit'])){
        $sql = mysqli_query($conn, "INSERT INTO `contacts` (`firstName`, `lastName`, `dayOfBirth`, `phone`, `gender`, `email`) VALUES('".$_POST['firstName']."', '".$_POST['lastName']."', '".$_POST['birthday']."', '".$_POST['phone']."', '', '".$_POST['email']."')");
    }

    mysqli_close($conn);
?>

以下是我使用bootstrap的联系表格：

<div class="container">
  <div class="row">
<h2>Contact Form</h2>
<form class="form-horizontal" method="POST">
      <div class="form-group">
        <label class="control-label col-xs-2">First Name:</label>
        <div class="col-xs-10">
          <input type="text" class="form-control" name="firstName" placeholder="First Name">
        </div>
  </div>
      <div class="form-group">
        <label class="control-label col-xs-2">Last Name:</label>
        <div class="col-xs-10">
          <input type="text" class="form-control" name="lastName" placeholder="Last Name">
        </div>
  </div>
      <div class="form-group">
        <label class="control-label col-xs-2">DoB:</label>
        <div class="col-sm-6 col-md-2">
          <div class="input-group date" id="birthday">
        <input type="text" class="form-control" name="birthday">
        <span class="input-group-addon"> <span class="glyphicon glyphicon-calendar"></span> </span> </div>
        </div>
  </div>
      <div class="form-group">
        <label class="control-label col-xs-2">Phone/Mobile:</label>
        <div class="col-xs-10">
          <input type="text" class="form-control" name="phone" placeholder="Phone/Mobile">
        </div>
  </div>
      <div class="form-group">
        <label class="control-label col-xs-2">Gender:</label>
        <div class="col-xs-10">
          <label class="radio-inline">
        <input type="radio" name="gender" value="M">
        Male</label>
          <label class="radio-inline">
        <input type="radio" name="gender" value="F">
        Female</label>
        </div>
  </div>
      <div class="form-group">
        <label class="control-label col-xs-2">Email:</label>
        <div class="col-xs-10">
          <input type="email" class="form-control" name="email" placeholder="Email">
        </div>
  </div>
      <div class="form-group">
      <div class="col-xs-offset-2 col-xs-10">
          <button type="submit" class="btn btn-primary" name="submit" value="Submit">Submit</button>
      </div>
  </div>
    </form>
  </div>
</div>

似乎$conn没有问题，我可以无错误地连接到数据库，但查询可能有问题。当我提交时，没有数据插入数据库，但是，它不会显示错误。

此外，如果需要，db中的所有列都被允许NULL，我还有1个名为id的列（ auto_increment ），并提醒，我想要插入phpmyadmin，而不是mysql。任何人都可以帮我找出问题所在吗？

P / s：我使用wampserver，如果它确实重要。

P / s 2：发现错误!!!

Answer 1

确保您确实已连接到数据库。然后将action属性添加到引导程序表单中。

<form class="form-horizontal" action="page where insert code happens" method="POST">

Answer 2

您在查询代码中犯了一些语法错误。试试这个......工作!!

另外，请注意您正在插入MYSQL，它是WAMP或XAMP堆栈的一部分。 PHPMYADMIN是管理数据库的管理部分。

<?php
    $conn = mysqli_connect('localhost', 'root', '', 'db_sandbox');

    if (!$conn) {
     echo "Error: Unable to connect to MySQL." . PHP_EOL;
     echo "Debugging errno: " . mysqli_connect_errno() . PHP_EOL;
     echo "Debugging error: " . mysqli_connect_error() . PHP_EOL;
     exit;
    }

    if(isset($_POST['submit'])){
        $firsname = $_POST['firstName'];
        $lastName = $_POST['lastName'];
        $birthday = $_POST['birthday'];
        $phone = $_POST['phone'];
        $gender = $_POST['gender'];
        $email = $_POST['email'];

        $query = "INSERT INTO contacts (firstName, lastName, dayOfBirth, phone, gender, email) VALUES('".$firsname."', '".$lastName."', ".$birthday.", ".$phone.", '".$gender."', '".$email."')";
        $sql = mysqli_query($conn, $query);


    }

    mysqli_close($conn);
?>
