Question

我试图在表中插入值，但我不知道发生了什么事，这完全不起作用，我也看不到任何错误。

我不知道我在哪里做错了，任何人都可以帮助我。

这是我的代码：

Database.php

    <?php
$host = 'localhost';
$db   = 'pes';
$user = 'root';
$pass = '';
$charset = 'utf8';

$dsn = "mysql:host=$host;dbname=$db;charset=$charset";
$opt = [
    \PDO::ATTR_ERRMODE            => \PDO::ERRMODE_EXCEPTION,
    \PDO::ATTR_DEFAULT_FETCH_MODE => \PDO::FETCH_ASSOC,
    \PDO::ATTR_EMULATE_PREPARES   => false,
];
$pdo = new \PDO($dsn, $user, $pass, $opt);
?>

contentprocess.php

   <?php

class ContentProcess {
    /* Properties */
    private $conn;

    /* Get database access */
    public function __construct(\PDO $pdo) {
        $this->conn = $pdo;
    }

    function ContentProcess() {
        global $session;
        if (isset($_POST['createnewcontent'])) {
            $this->createnewcontent();
        } 
      }


     public function createnewcontent()
    {
        $description = $_POST['description'];
        $typeofpage = $_POST['typeofpage'];
        $time = time();
        $q = "INSERT INTO content VALUES ('', '$description', '$typeofpage', '1', '$time', '1', '$time')";
        $this->conn->query($q);
        header("Location:content.php");
    }

    function getcontentdescription() {
         return $this->conn->query("SELECT description FROM content")->fetchAll();
    }

}

表单代码：

content.php

<?php 
include("include/header.php");
include("include/database.php");
include 'contentprocess.php';
?>
    <div class="modal fade" id="createGroup" tabindex="-1" role="dialog" aria-labelledby="createGroup" aria-hidden="true">

您尚未创建此类“ ContentProcess”的对象。在文件中进行这些更改。 *确保您的SQL查询正确

content.php

<?php 
include("include/header.php");
include("include/database.php");
require_once('contentprocess.php');
$contentProcess = new ContentProcess();
if(isset($_POST['submit'])){
    $contentProcess->createnewcontent();
}
?>
    <div class="modal fade" id="createGroup" tabindex="-1" role="dialog" aria-labelledby="createGroup" aria-hidden="true">
