使用GUMP PHP类验证数据

Question

请注意，在stackoverflow上有一个问题"在Slimphp上使用GUMP验证数据"，但我问的这个问题不是重复的。

我想使用GUMP PHP输入验证类来验证我的表单数据(可在https://github.com/Wixel/GUMP上找到)，但无法弄清楚如何将其附加到我的表单。

这是一个非常直接的GUMP的例子

<?php
require "../gump.class.php";
$validator = new GUMP();
// Set the data
$_POST = array( 
    'username' => 'Sisi', 
    'password' => 'mypassword', 
    'email'    => '[e-mail]', 
    'gender'   => 'm', 
    'bio'      => 'This is good! I think I will switch to another language');
$_POST = $validator->sanitize($_POST); // You don't have to sanitize, but it's safest to do so.
// Let's define the rules and filters
$rules = array( 
'username' => 'required|alpha_numeric|max_len,100|min_len,6',
'password' => 'required|max_len,100|min_len,6',
'email'    => 'required|valid_email',
'gender'   => 'required|exact_len,1',
'bio'      => 'required');
$filters = array( 
'username'    => 'trim|sanitize_string',
'password'    => 'trim|base64_encode',
'email'       => 'trim|sanitize_email',
'gender'      => 'trim');
$_POST = $validator->filter($_POST, $filters);
// You can run filter() or validate() first
$validated = $validator->validate($_POST, $rules);
// Check if validation was successful
if($validated === TRUE)
{
    echo "Successful Validationnn";
    print_r($_POST); // You can now use POST data safely
    exit;
}else{
    // You should know what form fields to expect, so you can reference them here for custom messages
    echo "There were errors with the data you provided:n";
    // Or you can simply use the built in helper to generate the error messages for you
    // Passing a boolean true to is returns the errors as html, otherwise it returns an array
    echo $validator->get_readable_errors(true);
}

现在，我为测试目的创建了一个演示表单，它收集用户名和密码并将其打印出来

<?php
if ($_SERVER["REQUEST_METHOD"] == "POST") {
$user_name = $_POST["user_name"];
$user_password = $_POST["user_password"];
echo $user_name;
echo $user_password;
}

我知道我需要替换这个

$_POST = array('username' => 'Sisi', 'password' => 'mypassword', 'email' => [e-mail]', 'gender' => 'male', 'bio' => 'This is good! I think I will switch to another language');

$user_name = $_POST["user_name"]; $user_password = $_POST["user_password"];

但我就是不能。

你能帮忙吗?

试试这个

<?php
require "../gump.class.php";
if ($_SERVER["REQUEST_METHOD"] == "POST")
{
$validator = new GUMP();
$user_name = $_POST['user_name'];
$user_password = $_POST['user_password'];
$_POST = array(
    'username' => $user_name,
    'password' => $user_password);
$_POST = $validator->sanitize($_POST); // You don't have to sanitize, but it's safest to do so.
// Let's define the rules and filters
$rules = array( 
'username' => 'required|alpha_numeric|max_len,100|min_len,6',
'password' => 'required|max_len,100|min_len,6');
$filters = array( 
'username'    => 'trim|sanitize_string',
'password'    => 'trim|base64_encode');
$_POST = $validator->filter($_POST, $filters);
// You can run filter() or validate() first
$validated = $validator->validate($_POST, $rules);
// Check if validation was successful
if($validated === TRUE)
{
    echo $user_name;
    echo $user_password;
    exit;
}else{
    // You should know what form fields to expect, so you can reference them here for custom messages
    echo "There were errors with the data you provided:n";
    // Or you can simply use the built in helper to generate the error messages for you
    // Passing a boolean true to is returns the errors as html, otherwise it returns an array
    echo $validator->get_readable_errors(true);
}
