在MySQL列中没有插入多个复选框值

我知道这个问题已经被多次询问过了，我已经尝试了给定的解决方案，但是没有一个似乎不适用于我的脚本。 D：任何人都会善待启发我，我做错了什么？在MySQL列中没有插入多个复选框值

这里的HTML脚本的一部分：

<td class="tableBody"> 
    <input type="checkbox" name="category[]" value="Website" /> Website 
    <input type="checkbox" name="category[]" value="Members" /> Members 
    <input type="checkbox" name="category[]" value="Updates" /> Updates 
    <input type="checkbox" name="category[]" value="Cons" /> Cons 
    <input type="checkbox" name="category[]" value="Others" /> Others 
</td>

这是MySQL的脚本的一部分：

$title = htmlspecialchars(strip_tags($_POST['title'])); 
    $entry = $_POST['entry']; 
    $cat = implode(",", $_POST['category']); 

    date_default_timezone_set('Asia/Manila'); 
    $timestamp = date('Y-m-d H:i:s'); 

    $entry = nl2br(htmlentities($entry, ENT_QUOTES, 'UTF-8')); 

    if (!get_magic_quotes_gpc()) { 
      $title = addslashes($title); 
      $entry = addslashes($entry); 
     } 

    $insert = "INSERT INTO `blog` (`id`, `username`, `entry_id`, `title`, `entry`, `category`, `timestamp`) VALUES ('$id', '$name', '', '$title', '$entry', '$cat', '$timestamp');";

的形式工作正常，只有类别未插入柱。

在此先感谢！

表中的“category”列的类型是什么？如果您打印它，“$ cat”的价值是多少？ –

'category'列的数据类型必须是varchar，如果它是'int' –

它的varchar，而不是int @PathikVejani – Aki

除了你的类别的数据类型，一切似乎都很好。它可能不是varchar。尝试使用varchar。你的查询可以显示一些警告，使用

error_reporting(E_ALL); ini_set('display_errors', 1);

对错误报告，然后手动解决查询。

你能试试这条线改变这种basicly添加（阵列）..

$cat = implode(",", (array)$_POST['category']);

如果不是作品再看看这一点;我添加一些行添加这些，看看是否有错误或类似的东西。可能存在数据库连接或数据库结构问题。你可以看看是否有错误。我测试了它，它为我工作。

<?php 
     $title = htmlspecialchars(strip_tags($_POST['title'])); 
     $entry = $_POST['entry']; 
     $cat = implode(",", $_POST['category']); 
     echo $cat; 
     date_default_timezone_set('Asia/Manila'); 
     $timestamp = date('Y-m-d H:i:s'); 

     $entry = nl2br(htmlentities($entry, ENT_QUOTES, 'UTF-8')); 

     if (!get_magic_quotes_gpc()) { 
       $title = addslashes($title); 
       $entry = addslashes($entry); 
      } 

      //I add these lines from here, to... 
      $servername = "localhost"; 
      $username = "root"; 
      $password = ""; 
      $dbname = "code"; 

      // Create connection 
      $conn = new mysqli($servername, $username, $password, $dbname); 
      // Check connection 
      if ($conn->connect_error) { 
       die("Connection failed: " . $conn->connect_error); 
      } 

      $sql = "INSERT INTO `blog` (`id`, `username`, `entry_id`, `title`, `entry`, `category`, `timestamp`) VALUES ('$id', '$name', '', '$title', '$entry', '$cat', '$timestamp');"; 

      if ($conn->query($sql) === TRUE) { 
       echo "New record inserted successfully"; 
      } else { 
       echo "Error: " . $sql . "<br>" . $conn->error; 
      } 

      $conn->close(); 

      //Here... 
    ?>

嗨，我也尝试了基本的数组，并没有发生任何事情。至于连接，它已经有了，否则它不会在mysql中插入其他的字段。谢谢:) – Aki

因此，您的表单中可能存在问题，您可以分享您的表单吗？ – marlonjd

按IMBS”的建议，我已经把它在注释中（备查），因为它不影响对类别阵列通过移动SQL数据删除原来的foreach循环，并做了一些调整在它下面，它现在工作正常。 :)
