我有一个自定义联系人表单，我正试图在其他文件中处理该表单：

表格：

<form method="post" action="<?php echo get_template_directory_uri() . \'/templates/contact.php\' ?>" name="contactform" id="contactform">
                <div class="col-sm-6">
                    <fieldset>
                        <input name="name" type="text" id="name" size="30" value="" placeholder="Name" />
                        <br />
                        <input name="email" type="text" id="email" size="30" value="" placeholder="Email" />
                        <br />
                        <input name="phone" type="text" id="phone" size="30" value="" placeholder="Phone" />
                        <br />
                    </fieldset>
                </div>
                <div class="col-sm-6">
                    <fieldset>
                        <textarea name="comments" cols="40" rows="8" id="comments" placeholder="Message"></textarea>
                        <button type="submit" class="btn btn-green-border btn-lg" id="submit" value="submit">Send Message</button>
                        <input type="hidden" name="address" value="<?php echo $t_one_opt[\'contact_email\'] ?>">
                    </fieldset>
                </div>
            </form>

但在处理文件中，我可以实现获取选项值。我正在使用Redux框架，并且在所有站点中都工作得很好。我也加入了全局变量。

联系php

<?php
if(!$_POST) exit;

global $t_one_opt;

$name     = $_POST[\'name\'];
$email    = $_POST[\'email\'];
$phone   = $_POST[\'phone\'];
$comments = $_POST[\'comments\'];


if(trim($name) == \'\') {
    echo \'<div class="alert alert-danger text-center">Please enter your name.</div>\';
    exit();
} else if(trim($email) == \'\') {
    echo \'<div class="alert alert-danger text-center">Please enter a valid email address.</div>\';
    exit();
} else if(trim($phone) == \'\') {
    echo \'<div class="alert alert-danger text-center">Please enter a valid phone number.</div>\';
    exit();
} else if(!is_numeric($phone)) {
    echo \'<div class="alert alert-danger text-center">Phone number can only contain digits.</div>\';
    exit();
} else if(!isEmail($email)) {
    echo \'<div class="alert alert-danger text-center">You have enter an invalid e-mail address,please try again.</div>\';
    exit();
}

if(trim($comments) == \'\') {
    echo \'<div class="alert alert-danger text-center">Please enter your message.</div>\';
    exit();
} 

if(get_magic_quotes_gpc()) {
    $comments = stripslashes($comments);
}


// Configuration option.
// Enter the email address that you want to emails to be sent to.
// Example $address = "[email protected]";

//$address = "[email protected]";
//global $t_one_opt;
$address = $t_one_opt[\'contact_email\'];


// Configuration option.
// i.e. The standard subject will appear as, "You\'ve been contacted by John Doe."

// Example, $e_subject = \'$name . \' has contacted you via Your Website.\';

$e_subject = \'You\\\'ve been contacted by \' . $name . \'.\';


// Configuration option.
// You can change this if you feel that you need to.
// Developers, you may wish to add more fields to the form, in which case you must be sure to add them here.

$e_body = "You have been contacted by $name with regards to $subject, their additional message is as follows." . PHP_EOL . PHP_EOL;
$e_content = "\\"$comments\\"" . PHP_EOL . PHP_EOL;
$e_reply = "You can contact $name via email, $email or via phone $phone";

$msg = wordwrap( $e_body . $e_content . $e_reply, 70 );

$headers = "From: $email" . PHP_EOL;
$headers .= "Reply-To: $email" . PHP_EOL;
$headers .= "MIME-Version: 1.0" . PHP_EOL;
$headers .= "Content-type: text/plain; charset=utf-8" . PHP_EOL;
$headers .= "Content-Transfer-Encoding: quoted-printable" . PHP_EOL;

if(mail($address, $e_subject, $msg, $headers)) {

    // Email has sent successfully, echo a success page.

    echo "<fieldset>";
    echo "<div class=\'alert alert-success text-center\'>";
    echo "<h3>Wohoooo ! Well done </h3>";
    echo "<p>Thank you <strong>$name</strong>, your message has been submitted to us.</p>";
    echo "</div>";
    echo "</fieldset>";

} else {

    echo \'ERROR!\';
}

它也不识别Wordpress函数。

为什么这个文件在WordPress中“过期”？
