有人可以帮我,我的密码重置表格有点乱,我真的很新的PHP和MySQL所以请不要责怪我弄错了。但我真的需要一些帮助。
基本上一切正常,它允许用户输入电子邮件,然后向他们发送新密码。 (我已经附上了发送邮件/密码的代码,因为我不需要帮助。)唯一的问题是它没有检查电子邮件,它没有检查我的数据库中是否存在电子邮件,它让用户输入他们想要的任何电子邮件。但如果他们输入的数据库不在数据库中,我希望它说抱歉,不存在该类型的电子邮件或其他内容。我需要知道如何检查用户输入的电子邮件是否确实存在。
然后要么说发了电子邮件,要么就出现了问题。
<?php
$page_title = "Login";
include('includes/header.php');
include ('includes/mod_login/login_form2.php');
if(!isset($_GET['err']) || isset($_GET['err'])=='') {
$_GET['err'] = '0';
}
?>
<?
$html_form = "<form name=\"forgotpasswordform\" action=\"sendpassword.php\" method=\"post\">
<table border=\"0\" cellspacing=\"0\" cellpadding=\"3\" width=\"100%\">
<tr>
<td width=\"15%\">Email Address:</td>
<td><input name=\"forgotpassword\" type=\"text\" value=\"\" id=\"forgotpassword\" size=\"30\"/></td>
</tr>
<tr>
<td> </td>
</tr>
<tr>
<td colspan=\"2\"><input type=\"submit\" name=\"submit\" value=\"Submit\" class=\"mainoption\" /></td>
</tr>
</table>
</form>";
if ($_GET['err'] == '1') { //error if message is not filled ?>
<? echo $html_form; ?>
<?
} else if ($_GET['err'] == '2') { // error if email is not found
?>
<h1> </h1>
<p>
Email Not Found!
</p>
<br />
<?
} else if ($_GET['err'] == '3') { // EMAIL SENT :D
?>
<h1> </h1>
<p>
Thanks! Your new password has been sent.
</p>
<br />
<?
} else if ($_GET['err'] == '0') { // otherwise print email form
?>
<? echo $html_form; ?>
<?
}
?>
然后我们链接到sendpassword.php:
<?php
/**

* Password Reset - Used for allowing a user to reset password

* @version 0.0.1
* @package ShuttleCMS
*/
define('IN_SCRIPT', true);
// Start a session
session_start();
//Connect to the MySQL Database
include 'includes/_config/connection.php';
/*
* Checks form field for email
*/
if ($_POST['forgotpassword']=='') {
header('Location: http://localhost/ptb1/recover_password.php?err=1');
}
if(get_magic_quotes_gpc()) {
$forgotpassword = htmlspecialchars(stripslashes($_POST['forgotpassword']));
}
else {
$forgotpassword = htmlspecialchars($_POST['forgotpassword']);
}
/*
* Checks if the email exists
*/
$sql = "SELECT COUNT(*) FROM ptb_users WHERE email = '$forgotpassword'";
$result = mysql_query($sql)or die('Could not find member: ' . mysql_error());
if (!mysql_result($result,0,0)>0) {
header('Location: http://localhost/ptb1/recover_password.php?err=2');
}
答案 0 :(得分:1)
你正在寻找这样的东西:
if(mysql_num_rows($result)) {
// user found
} else {
// no user found
}
请记住,您的代码对sql注入是开放的,您不应该使用mysql_
扩展名。请改用PDO。
