Question

我遇到了问题。这是我编辑文章的代码。我不知道为什么，但我的更新不起作用。它只是重定向到../index.php。我尝试了一切（引号和东西也.. .. ..你能帮助我吗？我只想编辑/更新标题和内容。代码如下。非常感谢。

editarticle.php

<?php

session_start();

include_once('../connect.php');
include_once('../includes/article.php');
header('Content-type: text/html; charset=utf-8');

if(isset($_SESSION["user_id"])){
 $query=$pdo->prepare("SELECT * FROM users WHERE id = " 
 .$_SESSION["user_id"] );
  $query->execute();
  $row=$query->fetch(PDO::FETCH_ASSOC);

  if($row['privileges']==1){
   $query = $pdo->prepare("SELECT * FROM `articles` WHERE article_id='" . 
   $_POST['id'] . "'");
   $query->execute();
   $row=$query->fetch(PDO::FETCH_ASSOC);
    var_dump($row);

     if(isset($_POST['editarticle'])){
      if(isset($_POST['title'], $_POST['content'])){
        $title= $_POST['title'];
        $content= nl2br($_POST['content']);

          $query= $pdo->prepare("UPDATE `articles` SET article_title=" 
     .$_POST['title'] .",article_content=" .$_POST['content'] ." WHERE 
      article_id='" . $_POST['id'] . "'");
          $query->execute();
          $row=$query->fetch(PDO::FETCH_ASSOC);

          header('Location: ../index.php');
       }
