Question

我正在处理登录表单。我已经使用password_hash函数完成了我的注册表单，并以这种方式成功地将所有密码保存在我的数据库中。

我不知道我将把passwod_verify函数放在哪里以及我必须准确编码验证以便将普通的txt密码与散列版本进行比较？我知道我需要将这个问题分成两部分： 1）检查用户名后，从我的数据库中获取hashedpassword。 2）将其与用户输入密码进行比较，以验证并允许用户登录。

我的代码在下面，也是我数据库的一部分。

  <?php require_once('Connections/bankusers.php'); ?>
<?php session_start(); ?>
<?php
if (!function_exists("GetSQLValueString")) {
function GetSQLValueString($theValue, $theType, $theDefinedValue = "", $theNotDefinedValue = "")
{
if (PHP_VERSION < 6) {
$theValue = get_magic_quotes_gpc() ? stripslashes($theValue) : $theValue;
}
$theValue = function_exists("mysql_real_escape_string") ? mysql_real_escape_string($theValue) : mysql_escape_string($theValue);
switch ($theType) {

$theValue = ($theValue != "") ? "'" . $theValue . "'" : "NULL";

Answer 1

我将忽略此表单的安全性，只关注您的要求。你需要改变

$password=$_POST['Password:'];

对此（假设您只在数据库中存储md5哈希）：

$password=md5($_POST['Password:']);

我在哪里把password_verify函数放在我的代码中？
