我需要一点帮助，这是我网站上唯一缺少的部分。我有一个时事通讯脚本，在第一页我使用的是一个从codecanyon（PHPMLC）获得的多语言函数，它非常有效。
这是带有表单的index.php（我已经去掉了不必要的html）。
<?php
require_once( "../PHPMLC/class/PHPMLC.php" );
$ml = new PHPMLC();
$ml_languages = $ml->getLanguages();
$ml_selected_language_code = $ml->getCurrentLanguageCode();
$ml_strings = $ml->getTranslatedStringsForCurrentLanguage();
?>
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<title><?php echo $ml_strings['prereg_m_title']; ?></title>
<link href="/css/style.css" rel="stylesheet">
</head>
<body class="Site">
<form class="form-horizontal" id="newsletter" action="send.php" method="post" accept-charset="utf-8"
enctype="multipart/form-data">
<div class="form-group">
<label for="inputEmail3" class="col-sm-2 control-label">Email</label>
<div class="col-sm-6">
<input type="email" name="signup-email" class="form-control" id="signup-email" value=""
pattern="[A-Z-a-z-0-9-_@.]+" autocomplete="off" required />
<input type="hidden" name="signup-gender" id="signup-gender" value="female" />
</div>
</div>
<div class="form-group">
<label for="inputPassword3"
class="col-sm-2 control-label"><?php echo $ml_strings['prereg_country_label']; ?></label>
<div class="col-sm-6">
<select class="form-control" name="signup-country" required />
<option value="" disabled selected><?php echo $ml_strings['prereg_please_select']; ?></option>
<option value="Albania">Albania</option>
<option value="Andorra">Andorra</option>
<option value="Austria">Austria</option>
<option value="Belarus">Belarus</option>
<option value="Belgium">Belgium</option>
</select>
</div>
</div>
<div class="form-group">
<div class="col-sm-offset-2 col-sm-6">
<button type="submit" class="btn btn-info"><?php echo $ml_strings['prereg_submit_button']; ?></button>
</div>
</div>
</form>
</body>
</html>
表单将输入发送到文件"send.php"，该文件具有以下代码：
<?php
require 'inc/Database.class.php';
class Newsletter {
private static $email;
private static $gender;
private static $country;
private static $ip;
private static $datetime = null;
private static $valid = true;
public function __construct() {
die( 'Init function is not allowed' );
}
public static function register( $email ) {
if ( ! empty( $_POST ) ) {
self::$email = $_POST['signup-email'];
self::$gender = $_POST['signup-gender'];
self::$country = $_POST['signup-country'];
//Test if it is a shared client
if ( ! empty( $_SERVER['HTTP_CLIENT_IP'] ) ) {
self::$ip = $_SERVER['HTTP_CLIENT_IP'];
//Is it a proxy address
} elseif ( ! empty( $_SERVER['HTTP_X_FORWARDED_FOR'] ) ) {
self::$ip = $_SERVER['HTTP_X_FORWARDED_FOR'];
} else {
self::$ip = $_SERVER['REMOTE_ADDR'];
}
self::$datetime = date( 'Y-m-d H:i:s' );
if ( empty( self::$email ) ) {
$status = "error";
$message = "The email address field must not be blank";
self::$valid = false;
} else if ( ! filter_var( self::$email, FILTER_VALIDATE_EMAIL ) ) {
$status = "error";
$message = "You must fill the field with a valid email address";
self::$valid = false;
}
if ( self::$valid ) {
$pdo = Database::connect();
$pdo->setAttribute( PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION );
$existingSignup = $pdo->prepare( "SELECT COUNT(*) FROM signups WHERE signup_email_address='$email'" );
$existingSignup->execute();
$data_exists = ( $existingSignup->fetchColumn() > 0 ) ? true : false;
if ( ! $data_exists ) {
$sql = "INSERT INTO signups (signup_email_address, signup_category, signup_country, signup_ip, signup_date) VALUES (:email, :gender, :country, :ip, :datetime)";
$q = $pdo->prepare( $sql );
$q->execute(
array( ':email' => self::$email,
':gender' => self::$gender,
':country' => self::$country,
':ip' => self::$ip,
':datetime' => self::$datetime
) );
if ( $q ) {
$status = "success";
$message = "Your registration was successful";
} else {
$status = "error";
$message = "An error occurred, please try again";
}
} else {
$status = "error";
$message = "This email is already registered";
}
}
$data = array(
'status' => $status,
'message' => $message
);
echo json_encode( $data );
Database::disconnect();
}
}
}
if ( ! empty( $_POST ) ) {
$email = $_POST['signup-email'];
$gender = $_POST['signup-gender'];
$country = $_POST['signup-country'];
Newsletter::register( $email );
}
?>
我的问题是，我无法翻译send.php中的错误/警报消息。我的意思是，我不能使用密钥$ml_strings['reg_successful'];代替"您的注册成功了"。这让我发疯，因为我是个业余爱好者。
非常感谢您的帮助。
send.php的执行与index.php的执行完全分离，因此需要初始化这两个文件中的$ml_strings变量。换句话说，将以下行添加到send.php中的Newsletter类：
$ml_strings = $ml->getTranslatedStringsForCurrentLanguage();
