【问题描述】：
我正在尝试通过 php 脚本register.php 将表单数据发布到数据库来注册新用户，但是当我点击注册时出现一系列错误，数据应该由第二个脚本验证叫validate.php。我的register.php 如下所示。表单为空和填写时存在相同的错误。
<?php require('scripts/validate.php');?>
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8" />
<title>Register</title>
<body>
<div id="mainWrapper">
<div id="register">
<?php if(isset($error)){echo "<div id='error'>".$error."</div>";}?>
<?php if(isset($success)){echo "<div id='success'>".$success."</div>";}?>
<form method="post" action="" >
<fieldset>
<legend>Register Here</legend>
<p>
<label for="Username">Username</label>
<input type="text" id="username"/>
</p>
<p>
<label for="Email">Email</label>
<input type="text" id="email"/>
<p>
<label for="Firstname">Firstname</label>
<input type="text" id="firstname"/>
</p>
<p>
<label for="Lastname">Lastname</label>
<input type="text" id="lastname"/>
</p>
<p>
<label for="Password">Password</label>
<input type="password" id="password"/>
</p>
<p>
<label for="Re-Type Password">Re-Type Password</label>
<input type="password" id="password2"/>
</p>
<p>
<label for="DOB">DOB</label>
<input type="text" id="dob">
</p>
<p>
<label for="Adress">Adress</label>
<input type="text" id="address"/>
</p>
<p>
<label for="Adress 2">Adress 2</label>
<input type="text" id="address2"/>
</p>
<p>
<label for="town">Town</label>
<input type="text" id="town"/>
</p>
<p>
<label for="county">County</label>
<input type="text" id="county"/>
</p>
<p>
<label for="Postalcode">PostalCode</label>
<input type="text" id="postcode"/>
</p>
<p>
<label for="contactno">Contact No.</label>
<input type="text" id="contact"/>
</p>
<input type="submit" name="submit" value="Register"/>
</fieldset>
</form>
</div>
</div>
</body>
</html>
而 validate.php 在这里
<?php include('connection.php');?>
<?php
if(isset($_POST['submit']))
{
$username=$_POST['username'];
$email=$_POST['email'];
$firstname=$_POST['firstname'];
$lastname=$_POST['lastname'];
$password=$_POST['password'];
$password2=$_POST['password2'];
$dob=$_POST['dob'];
$address=$_POST['address'];
$address2=$_POST['address2'];
$town=$_POST['town'];
$county=$_POST['county'];
$postcode=$_POST['postcode'];
$contact=$_POST['contact'];
$fetch=mysql_query("SELECT id FROM users WHERE email='$email'")or die(mysql_error());
$num_rows=mysql_num_rows($fetch);
if(empty($username)||empty($email) || empty($firstname) || empty($lastname) || empty($password) || empty($password2) || empty($dob) || empty($address) || empty($town)|| empty($postcode) || empty($contact))
{
$error= 'ALl * fields are required';
}
elseif (!filter_var($email,FILTER_VALIDATE_EMAIL))
{
$error= 'A valid email is required';
}
elseif (!empty($contact))
{
if (!is_numeric($contact))
{
$error= 'Enter a valid contact No.';
}
}
elseif ($password !=$password2)
{
$error= "Passwords don't match";
}
elseif ($num_rows >=1)
{
$error='We already have this email registered,try a new one!';
}
else
{
$password=md5($password);
$sql=mysql_query("INSERT INTO user(username,email,firstname,lastname,password,dob,address,address2,town,county,postcode,contact)VALUES('$username','$email','$firstname','$lastname','$password','$dob','$address','$address2','$town','$county','$postcode','$contact')");
if($sql)
{
header("location:login.php");
}
}
}
?>
我会非常感谢你们。

没有

谢谢大家，我消除了这些错误。但是我仍然有一个问题，表单没有添加到数据库中，并且从连接脚本（connection.php）中收到此错误已弃用：mysql_connect（）：不推荐使用mysql扩展并将在将来删除：使用mysqli 或 PDO 在第 7 行的 C:\xampp\htdocs\Registration\scripts\connection.php 中。这里是连接脚本
