按照指示,我必须在虚线之间插入代码。应该刷新并查看“存在”我有正确的数据库、表,我很确定一切,但我认为不存在。我应该继续遵循指南还是我搞砸了?
如果我正确地遵循它,是否有人有保证工作的指南?
我的 login.php
<?php
include 'core/init.php';
-----------------------------------------
if (user_exists('alex') === true) {
echo "exists";
}
die('no exist');
-------------------------------------------
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[] = 'We can not find that user';
}
}
?>
我有 init.php
<?php
session_start();
error_reporting(0);
require 'database/connect.php';
require 'functions/general.php';
require 'functions/users.php';
$errors = array();
?>
我有 users.php
<?php
function user_exists($username) {
$username = sanitize($username);
$query = mysql_query("SELECT COUNT('user_id') FROM 'users' WHERE 'username' = '$username'");
return (mysql_result($query, 0) == 1) ? true : false;
}
?>
i have general.php
<?php
function sanitize($data) {
return mysql_real_escape_string($data);
}
?>
我用:
<form action="login.php" method="post">
注意:如果有人熟悉 phpacademy,我会按照他的指南进行操作
