Question

我有一个包含以下php代码的页面：

 <?php

   include ('databaseconnect1.php');

     $sql1= "SELECT Categoryid, Categoryname, Categorydescription 
            FROM Categories";
     $result1 = mysqli_query($db,$sql1);

   if (!$result1){
    echo "<font color = 'Green' .<p> No Category Found, Contact the 
          administrator </p> </font>";
  }

 function getPosts()
  {
   $posts = array();
   $posts[0] = $_POST['topic_subject'];
   $posts[1] = $_POST['date'];
   $posts[2] = $_POST['topic_category'];
   $posts[3] = $_SESSION['userid'];
   return $posts;
  } 

 if (isset($_POST['createtopicbutton'])) 
  {           
 $data = getPosts();

   $sql2 = "INSERT INTO Topics(Topic_subject, Topic_date, 
              Topic_category, Topic_by)
          VALUES('$data[0]','$data[1]', '$data[2]', '$data[3]')";

   $result2 = mysqli_query($db,$sql2);

 if ($result2){
       echo  "<font color = 'Green' .<p> Topic Successfully Created </p> 
     </font>";
 }else{
     echo "<font color = 'Green' .<p> Topic NOT! Successfully Created </p>
             </font>"; //This is the result I am getting specifically
    }                                                   
   }
 ?>

这是同一页面上的HTML代码：

<form method = "post" action = "" > 
   <table cellspacing="15">

   <tr>
      <th>Subject </th>
      <td><input type = "text" name = "topic_subject" /> </td>
   </tr> 

   <tr>
      <th>Category </th>
      <?php echo '<td> <select name="topic_category"> ';

       while($row = mysqli_fetch_assoc($result1))
       {
       echo '<option value="' . $row['Categoryid'] . '">' . 
             $row['Categoryname'] . '</option>'; 
       }
     echo '</select></td>';
      ?>
   </tr> 

   <tr>
      <th>Current Date </th>
      <td><input type = "text" name = "date" /> </td>
   </tr>

   <tr>
     <th> </th>
     <td> <input type = "submit" value = "Create Topic!" name = 
           "createtopicbutton" /> </td>
   </tr> 

    </table>
  </form>

我需要帮助的具体部分是当按下“createtopicbutton”时，我只得到以下结果：

<?php Topic NOT! Successfully Created?>

以下是主题表的表格结构：Table Structure from phpmyadmin

这是整个数据库表结构的一部分：Linkages of tables

到目前为止，我已经尝试确保所有括号都已正确关闭，并且稍微改变语法并且没有成功。然而，唯一有效的是当我通过phpmyadmin输入数据时它会以某种方式工作。所以我觉得问题与表格有关。你能帮忙吗？

PHP查询未执行
