【问题描述】:
我有一个包含以下内容的 php 文件
- 用于为新用户收集数据的 html 文件
- 验证输入数据的 php 函数
- 在数据提交前提醒和提示用户的javascript代码
- 在验证过程之后,我想将输入数据移动到 insert.php 以将数据插入到数据库中。
下面是代码
<?PHP
session_start();
if (!(isset($_SESSION['login_user']) && $_SESSION['login_user'] != '')) {
header ("Location: loginForm.php");
}
$hash;
$salt;
?>
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<link rel="stylesheet" type="text/css" href="layout.css">
<script language="javascript" type="text/javascript" src="/templates/myjavascript.js"></script>
<title>Title of the document</title>
<script>
window.onload=function(){
document.getElementById("new_user_form").onsubmit=function(){
if(this.pword.value === this.pword2.value)
{ alert("Are you sure you want to create a new user")
return true;}
else{ alert("Paswords must be the same ");
return false;}
}
}
</script>
</head>
<div>
<body>
<section id="content">
<form align="center" class="form" action="create_user.php" method="post" id="new_user_form" name="new_user_form">
<ul>
<li>
<h2>Please Fill The Form</h2>
</li>
<li>
<label for="username">User Name</label>
<input name="username" id="keyword" type="text" placeholder="type first name (required)" required />
</li>
<li>
<label for="pword">Password</label>
<input name="pword" id="pword" type="password" placeholder="########" required />
</li>
<li>
<label for="pword2">Confirm Password</label>
<input name="pword2" id="pword2" type="password" placeholder="########" required />
</li>
<p>
<input type = "reset" class="reset" name="submit"/>
<input type ="submit" name="submit" value="submit" class="submit" "/>
</p>
</section>
</ul>
</form>
</body>
</div>
<?php
/* php function to check pasword policy
The password has to be alphanumeric and special characters minimum 8 and max 16
*/
function checkpwdPolicy(){
if($_POST['pword'] === $_POST['pword2']) {
if(!preg_match('/^(?=.*\d)(?=.*[A-Za-z])[0-9A-Za-z!@#$%]{8,16}$/', $_POST['pword'])) {
echo '<script> alert(" password requirement not met"); </script>';
} else{
/* we use the session varible to store the hashed password and username */
/
$_SESSION['pwd'] = password_hash($_POST['pword'], PASSWORD_DEFAULT);
$_SESSION['username'] = $_POST['username'];
header ("Location: insert_user_table.php");
}
}
else {echo "passwords do not match "; }
}
//tis is used to call the fucntion that checks the password policy
if(isset($_POST['submit']) && isset($_POST['username']) && isset($_POST['pword']) && isset($_POST['pword2']) )
{checkpwdPolicy();}
?>
</html>
当我运行 cod 时,会显示以下错误。 以下是错误。
问题是如何将数据移动到将数据插入数据库的文件中。
【问题讨论】:
-
将您的
checkpwdPolicy()放在文件上的<html>之前,这样可以解决您的问题。 -

@Disha V 谢谢你的建议解决了我的问题
