Question

我想处理我的评论，其中包含名称，电子邮件和消息到名为“评论”的数据库，但它不能。我确信phpmyadmin中的数据库名称与prosescomment.php中的相同。请帮忙

这是我的表格

<form action="prosescomment.php" method="POST"  id="form" >
          <div class="success_wrapper">
            <div class="success">Contact form submitted!<br>
              <strong>We will be in touch soon.</strong> </div>
          </div>
          <fieldset>
              <input type="text" name="nama" placeholder="Name:">
              <br class="clear">
              <span class="error error-empty">*This is not a valid name.</span><span class="empty error-empty">*This field is required.</span>
            <label class="email">
              <input type="text" name="email" placeholder="E-mail:">
              <br class="clear">
              <span class="error error-empty">*This is not a valid email address.</span><span class="empty error-empty">*This field is required.</span> </label>
            <label class="message">
              <textarea type="text" name="message" placeholder="Message"></textarea>
              <br class="clear">
              <span class="error">*The message is too short.</span> <span class="empty">*This field is required.</span> </label>
            <div class="clear"></div>
            <div class="btns"><a data-type="submit" class="link1">Send</a>
              <div class="clear"></div>
            </div>
          </fieldset>
        </form>

这是我的prosescomment.php

<?php 
    include "connection.php";

    $nama = $_POST['nama'];
    $email = $_POST['email'];
    $message = $_POST['message'];

    $query = "INSERT  INTO comment VALUES ('$nama', '$email', '$comment')";
    $result = mysql_query($query);

    if ($query) {
        header("location:index.html");
    }
    else{
        mysql_error();
    }
 ?>

Answer 1

似乎你有一个连接类左右......但是我建议你使用Prepared Statements＆amp; PDO ......

此外，您的SQL可能是错误的，具体取决于您是否有主键（ID）。

以下是我建议您前往的路线：

    <?php
    include "connection.php";

    $nama       = htmlspecialchars(trim($_POST['nama']));       //PROTECT AGAINST SQL INJECTION
    $email      = htmlspecialchars(trim($_POST['email']));      //PROTECT AGAINST SQL INJECTION
    $message    = htmlspecialchars(trim($_POST['message']));    //PROTECT AGAINST SQL INJECTION

    //NOTE: YOU DON'T HAVE THE VARIABLE $comment DEFINED: YOU MUST MEAN $message
    $query      = "INSERT  INTO comment (name, email, message) VALUES ('$nama', '$email', '$message')";

    /** I WOULD SUGGEST YOU USE PDO  & PREPARED STATEMENTS LIKE SO*/
    // $stmt       = $dbh->prepare("INSERT INTO comment (name, email, comment) VALUES (:name, :email, :message)");
    // $stmt->bindParam(':name', $nama);
    // $stmt->bindParam(':email', $email);
    // $stmt->bindParam(':message', $message);

    $result = mysql_query($query);
    // NOT if($query) BUT if($result) BECAUSE $query IS A STRING AND if($query) WILL ALWAYS RETURN TRUE... 
    if ($result) {
        header("location:index.html");
    }
    else{
        mysql_error();
    }
?>

我希望这有点帮助...

使用此代码查找您的html和prosescomment.php代码，它将运行

{{1}}

Answer 3

请将代码行<a data-type="submit" class="link1">Send</a>替换为<button class="link1" type="submit" >Send</button>，然后尝试发布您的表单数据。

为什么我不能将数据发布到我的数据库？
