我正在尝试设置一个注册框来创建新帐户。我正在尝试通过 ajax 加载 html 表单并将数据传递给 php 文件。
我想让包含表单的 div 每次点击“注册”按钮以从 php 脚本中获取结果并将其显示出来时重新加载。但是,我的代码似乎无法正常工作(处理 ajax 的 div 不会加载表单)。以下是我的代码:
注册.php:
<?php
session_start();
$email = $_POST['email'];
$email = mysql_real_escape_string($email);
$pwd = $_POST['pwd'];
$repwd = $_POST['repwd'];
$lname = $_POST['lname'];
$fname = $_POST['fname'];
$isValidEmail = 1;
if (substr_count($email, '@') != 1){
$isValidEmail = 0;
}
if($pwd != $repwd){ //check if password and re-entered passwords are the same
$_SESSION['error'] = 1;
$_SESSION['message'] = 'Password and Re-entered Password are different.';
} else if( strlen($pwd) < 6 || strlen($pwd) > 64 ) { //check if password is 6 - 64 characters
$_SESSION['error'] = 1;
$_SESSION['message'] = 'Password must be 6 - 64 characters.';
} else if( strlen($email) > 255) { //check if the email is too long
$_SESSION['error'] = 1;
$_SESSION['message'] = 'Email exceeded maximum length.';
} else if ($isValidEmail != 1){
$_SESSION['error'] = 1;
$_SESSION['message'] = 'Invalid Email.';
} else if (ctype_space($lname) || ctype_space($fname)){
$_SESSION['error'] = 1;
$_SESSION['message'] = 'Please enter your name.';
} else {
if ($mysqli = new mysqli("localhost", "root", "", "my_db")){
$stmt = $mysqli->prepare("SELECT email FROM users WHERE email = ?");
$stmt->bind_param('s',$email);
$stmt->execute();
$stmt->bind_result($result);
$stmt->fetch();
$stmt->close();
if ($result == $email) { //check if the input email exists in the database, duplicated user
$_SESSION['error'] = 1;
$_SESSION['message'] = 'Email '.$email.' is already used.';
} else {
$hash = hash('sha256', $pwd);
function createSalt()
{
$string = md5(uniqid(rand(), true));
return substr($string, 0, 3);
}
$salt = createSalt();
$hash = hash('sha256', $salt . $hash);
$stmt = $mysqli->prepare("INSERT INTO users ( email, lastName, firstName, password, salt )
VALUES ( ? , ?, ?, ? ,? )");
$stmt->bind_param('sssss', $email, $lname, $fname, $hash, $salt);
if ($stmt->execute()){
$_SESSION['message'] = 'Registered.';
} else {
$_SESSION['error'] = 1;
$_SESSION['message'] = 'Database query error occured.';
}
$stmt->close();
}
} else {
$_SESSION['error'] = 1;
$_SESSION['message'] = 'Error connecting to the database.';
}
}
header("Location: Home.php");
$mysqli->close();
?>
ajax.js:
$(document).ready(function() {
$('#submit_register').click(function(){
$('#register_form').submit( function(){
$.ajax({
type: 'POST',
url : 'Register.php',
data: $('#register_form').serialize(),
success: function () {
var myURL = "Register_form.php#register_div";
$('#ajaxHandle').load(myURL);
return false;
},
});
});
});
});
注册表格.php:
<!DOCTYPE html>
<html lang="en">
<head>
<?php session_start(); ?>
<meta charset="utf-8" />
<title></title>
</head>
<body>
<div class="span-23 prepand-top last" id="register_div" style="background:gray;">
<div id="wrapper_register" class="span-21 last" style="padding-top: 20px; padding-left:20px; padding-bottom:20px;">
<form id="register_form" action="register.php" method="post">
<legend class="large">Register</legend>
<?php
if ($_SESSION['message']){
$class = "";
if ($_SESSION['error']){
$class = "error";
} else {
$class = "success";
}
echo "<div class=\"$class span-4 last\">";
echo $_SESSION['message'];
echo "</div>";
unset ($_SESSION['error']);
unset ($_SESSION['message']);
}
?>
<div class="span-23 prepand-top last">
<p>E-mail address: <br>
<input type="text" name="email" maxlength="255" /></p><br>
<p>Last Name: <br><input type="text" name="lname" maxlength="255" /></p><br>
<p>First Name: <br>
<input type="text" name="fname" maxlength="255" /></p><br>
<p>Password: <br>
<input type="password" name="pwd" /><p class="quiet">6 - 64 characters</p><br>
<p>Re-enter Password: <br><input type="password" name="repwd" /></p><br>
<input id="submit_register" type="submit" value="Register" /><br>
</div>
</form>
</div>
</div>
</body>
</html>
我做错了什么?任何建议将被认真考虑。非常感谢!
