当我单击提交按钮而不输入任何字段时，我的错误处理似乎不起作用，我仍然可以登录我到底错过了什么？？看来我的验证不起作用，这是我在 login.php 下面的代码
<?php
include 'core/init.php';
if (empty($_post) === false) {
$username = $_post['username'];
$password = $_post['password'];
if (empty($username) === true || empty($password) === true) {
$errors[] = 'You need to enter a username and password';
} else if (user_exists($username) === false ) {
$errors[] = 'Username not found';
} else if (user_active($username) === false ){
$errors[] = 'You haven\' activated your account';
} else {
if (strlen($password) > 32){
$errors[] = 'Password too long';
}
$login = login($username, $password);
if($login === false){
$errors[] = 'That username/password combination is incorrect';
} else {
$_session['user_id'] = $login;
header('location: index.php');
exit();
}
}
} else {
$errors[] = 'No data recieved';
}
include 'includes/overall/header.php';
if (empty($errors) === false){
?>
<h2> we tried to log you in, but...</h2>
<?php
echo output_errors($errors);
}
include 'includes/overall/footer.php';
?>
我的 init.php
<?php
session_start();
require 'database/connect.php';
require 'functions/general.php';
require 'functions/users.php';
$errors = array();
?>
通用.php
<?php
function sanitize($data){
return mysql_real_escape_string($data);
}
function output_errors($errors) {
return '<ul><li>' . implode('</li><li>', $errors) . '</li></ul>';
}
?>
