我有一个表格，用户输入数据然后提交。然后，这将在表项目的数据库中创建一个条目。
如果用户输入所有细节，一切都运行良好，并且想法是如果有任何错误，则将其存储到数组中并打印给用户。
代码如下：
<?php
// This script performs an INSERT query to add a record to the users table.
$page_title = 'Create Project';
include('includes/header.php');
//check if user is logged in:
require('includes/login_functions.inc.php');
$loggedIn = false;
if ((isset($_COOKIE['user_id'])) && (!empty($_COOKIE['user_id'])) ) {
$loggedIn=true;
} else {
//redirect user to login
redirect_user('login.php');
}
// Check for form submission:
if ($_SERVER['REQUEST_METHOD'] == 'POST' && $loggedIn) {
require('includes/mysqli_connect.php'); // Connect to the db.
//$errors = array(); // Initialize an error array.
// Check for a project title
if (empty($_POST['project_title'])) {
$errors[] = 'You forgot to enter the project title.';
} else {
$p_title = mysqli_real_escape_string($dbc, trim($_POST['project_title'])); //we use mysqli_real_escape_string to avoid bad or malicious input
}
// Check for a project_description

但问题是，即使我提交没有条目的表单，也不会显示任何错误。数据库中没有创建任何行，但是我最终只得到了一个空白页面，并且仍然像预期的那样在createproject.php URL上。
