Question

更新2：我已经通过我自己解决了这个问题，如果我记得很清楚，代码如下：解析为正确的格式。更新：我找到了错误，我现在得到的最后一件事就是这个我将使用正确的预览错误发布回复。

致命错误：带有消息的未捕获异常'PDOException' 'SQLSTATE [42S22]：未找到列：1054未知列'标题' C：\ xampp \ htdocs \ Final \ include \ add_blog.php中的'字段列表'：56堆栈 trace：＃0 C：\ xampp \ htdocs \ Final \ include \ add_blog.php（56）： PDOStatement-＆gt; execute（）＃1 C：\ xampp \ htdocs \ Final \ addblog.php（194）： require（'C：\ xampp \ htdocs ...'）＃2 {main}引入第56行的C：\ xampp \ htdocs \ Final \ include \ add_blog.php

我正在尝试将以下数据插入数据库。但由于某种原因我得到了未定义的索引，即使我已经检查过并且两个变量里面都有值，你能用新的眼光看看它吗？（自定义我的添加用户代码）错误代码

注意：未定义的索引：用户输入   第53行的C：\ xampp \ htdocs \ Final \ include \ add_blog.php

我的代码

<?php

}
catch(PDOException $e)
{ 
echo $e->getMessage();
}


$title = $_POST['title']; 
$user = $_SESSION['username'];
$description = $_POST['description']; 
$content = $_POST['content'];   
$categories = "Basic";



//verifications

//password 

if (empty($title) || empty($user) || empty($description) || empty($content) || empty($categories)){
    $error = "Complete all fields";
}


if (strlen($content) == 30){
    $error = "Please Input some More content into your blog";
}




if(!isset($error)){


    //Securly insert into database
     $sql = 'INSERT INTO blogusers (title,user,description,content,categories) VALUES (:title,:user,:description,:content,:categories)';     
    $stmt = $conn->prepare($sql);
    $stmt->bindParam(':title',$title);
    $stmt->bindParam(':user',$user);
