[英]How to get the variable passed from another page when form is submitted
我正在处理核心php
密码reset
。
我将code
变量从reset.php
发送到resetPassword.php
页面,如下所示:
reset.php
$code = uniqid(true);
$url = "http://".$_SERVER['HTTP_HOST'].dirname($_SERVER['PHP_SELF'])."/resetPassword.php?code=$code"
resetPassword.php
global $code;
if(!isset($_GET['code'])){
echo "There is No Code there !!!";
}
if(isset($_GET['code'])){
$code = $_GET['code'];
echo "The code is set at first , just at visit of the page ".$code;
}
// make sure there is row in the table that matches that passed code
$findEmail = mysqli_query($link,"SELECT `email` from resetpasswords WHERE `code` = '$code' ");
if(mysqli_num_rows($findEmail)==0){ // if no row found
echo "<h2 class = 'text text-center'>No Record regarding this email !</h2>";
exit();
}
// when form submits
if(isset($_POST['reset'])){
$password = md5($_POST['password']);
$confirm = md5($_POST['confirm']);
if($password!=$confirm){
echo "Password Don't matches !";
exit();
}
$row = mysqli_fetch_array($findEmail);
$email = $_POST['email'];
$updatePass = mysqli_query($link,"UPDATE `user` SET user_password = '$confirm' where email = '$email'");
if($updatePass){
$query = mysqli_query($link,"DELETE FROM resetpasswords where code = '$code' ");
exit('Password Updated, Please Login with the New Password');
}
else{
exit('Something went wrong');
}
}
在同一页面resetPassword.php
,我有以下代码:
<form action="resetPassword.php" method="POST">
<div class="form-group">
<label for="password2">Password:</label>
<input type="password" class="form-control" name="password" id="password2" onkeyup="checkPass();">
</div>
<div class="form-group">
<label for="confirm2">Confirm Password:</label>
<input type="password" class="form-control" name="confirm" id="confirm2" onkeyup="checkPass();">
<span id="confirm-message2" class="confirm-message"></span>
</div>
<input type="hidden" value="<?php echo $code;?>">
<input type="submit" name="reset" value="Update Password" class="btn btn-success">
</form>
问题:
问题是当我提交表单时,它一直到页面顶部,并从顶部开始执行resetPassword.php
页面,因此对于resetPassowrd.php
页面,它无法get
该$code
多变的。
因为当我提交表单时, resetPassword.php
顶部的条件(!isset($_GET['code']))
变为真,它给了我: There is No Code there !!!
我想在提交表单时使用该$code
。
我试过的:
我尝试使用具有$code
值的hidden
字段,但这没有用。
请帮助我谢谢
考虑以下几点
1) 使用准备好的语句和参数化查询。
2) 使用password_hash()
和password_verify()
来保护您的密码。
3) 在resetPassword.php
页面中,如果您提交的表单带有action="resetPassword.php"
这将重定向到resetPassword.php。 所以用这个替换你的动作
$full_url = (isset($_SERVER['HTTPS']) && $_SERVER['HTTPS'] === 'on' ? "https" : "http") . "://{$_SERVER['HTTP_HOST']}{$_SERVER['REQUEST_URI']}";
<form action="<?php echo $full_url ?>" method="POST">
您在隐藏字段中缺少 name 属性,因此您无法找到 $code 的值。
代替
<input type="hidden" value="<?php echo $code;?>">
尝试
<input type="hidden" value="<?php echo $code;?>" name="code" />
