php订阅成功文本无法正常工作

Question

好的，所以基本上我有这个订阅输入，人们输入他们的电子邮件并单击一个按钮......一旦他们单击按钮，公司电子邮件就会收到新订阅者的通知（它会收到一封电子邮件，并在电子邮件中说明电子邮件用户输入）...无论如何我已经让它工作了，所以它会这样做并且还将用户输入的任何内容写入.txt文件。它一切正常，但是在我成功将它写入文本文件之后，成功文本点击订阅按钮后显示...

HTML：

        <div class="span12 subscribe">
            <h3>Subscribe to our newsletter</h3>
            <p>Sign up now to our newsletter and you'll be one of the first to know when the site is ready:</p>
            <form class="form-inline" action="assets/sendmail.php" method="post">
                <input type="text" name="email" placeholder="Enter your email...">
                <button type="submit" class="btn">Subscribe</button>
            </form>
            <div class="success-message"></div>
            <div class="error-message"></div>
        </div>

PHP：

<?php


// Email address verification

function isEmail($email) {
    return(preg_match("/^[-_.[:alnum:]]+@((([[:alnum:]]|[[:alnum:]][[:alnum:]-]*[[:alnum:]])\.)+(ad|ae|aero|af|ag|ai|al|am|an|ao|aq|ar|arpa|as|at|au|aw|az|ba|bb|bd|be|bf|bg|bh|bi|biz|bj|bm|bn|bo|br|bs|bt|bv|bw|by|bz|ca|cc|cd|cf|cg|ch|ci|ck|cl|cm|cn|co|com|coop|cr|cs|cu|cv|cx|cy|cz|de|dj|dk|dm|do|dz|ec|edu|ee|eg|eh|er|es|et|eu|fi|fj|fk|fm|fo|fr|ga|gb|gd|ge|gf|gh|gi|gl|gm|gn|gov|gp|gq|gr|gs|gt|gu|gw|gy|hk|hm|hn|hr|ht|hu|id|ie|il|in|info|int|io|iq|ir|is|it|jm|jo|jp|ke|kg|kh|ki|km|kn|kp|kr|kw|ky|kz|la|lb|lc|li|lk|lr|ls|lt|lu|lv|ly|ma|mc|md|mg|mh|mil|mk|ml|mm|mn|mo|mp|mq|mr|ms|mt|mu|museum|mv|mw|mx|my|mz|na|name|nc|ne|net|nf|ng|ni|nl|no|np|nr|nt|nu|nz|om|org|pa|pe|pf|pg|ph|pk|pl|pm|pn|pr|pro|ps|pt|pw|py|qa|re|ro|ru|rw|sa|sb|sc|sd|se|sg|sh|si|sj|sk|sl|sm|sn|so|sr|st|su|sv|sy|sz|tc|td|tf|tg|th|tj|tk|tm|tn|to|tp|tr|tt|tv|tw|tz|ua|ug|uk|um|us|uy|uz|va|vc|ve|vg|vi|vn|vu|wf|ws|ye|yt|yu|za|zm|zw)$|(([0-9][0-9]?|[0-1][0-9][0-9]|[2][0-4][0-9]|[2][5][0-5])\.){3}([0-9][0-9]?|[0-1][0-9][0-9]|[2][0-4][0-9]|[2][5][0-5]))$/i", $email));
}

if($_POST) {

    // Enter the email where you want to receive the notification when someone subscribes
    $emailTo = 'subscriptions@servready.com';

    $subscriber_email = ($_POST['email']);

    if(!isEmail($subscriber_email)) {
        $array = array();
        $array['valid'] = 0;
        $array['message'] = 'Insert a valid email address!';
        echo json_encode($array);
    }
    else {
        $array = array();
        $array['valid'] = 1;
        $array['message'] = 'Thanks for your subscription!';
        echo json_encode($array);

        // Send email
    $subject = 'New Subscriber!';
    $body = "You have a new subscriber!\n\nEmail: " . $subscriber_email;
        // uncomment this to set the From and Reply-To emails, then pass the $headers variable to the "mail" function below
    $headers = "From: ".$subscriber_email." <" . $subscriber_email . ">" . "\r\n" . "Reply-To: " . $subscriber_email;
    mail($emailTo, $subject, $body, $headers);
    }

    $data = $_POST['email']."\n";
    $ret = file_put_contents('data.txt', $data, FILE_APPEND | LOCK_EX);
    if($ret === false) {
        die('There was an error writing this file');
    }
    else {
        echo "$ret bytes written to file";
    }

}
?>

如果我删除这部分 php 脚本，则会弹出成功和无效的电子邮件文本：

$data = $_POST['email']."\n";
$ret = file_put_contents('data.txt', $data, FILE_APPEND | LOCK_EX);
if($ret === false) {
    die('There was an error writing this file');
}
else {
    echo "$ret bytes written to file";
}

就像我说的，它的功能，但成功文本或无效的电子邮件错误和成功文本不会与将人员电子邮件写入文本文件的代码一起弹出。

网站是http://servready.com 用于测试

根据上面的 cmets，它是在 echo json_encode 之后回显的内容——额外的内容会破坏回显的 JSON，从而导致其他所有内容都中断。

http://servready.com/assets/js/scripts.js 是包含倒计时时间的 JS 文件——它被硬编码到脚本中，所以这就是它重新开始的原因。您需要在其中放置一些代码来确定倒计时反映的适当时间。我建议您尝试一下，然后针对您可能需要帮助的任何问题发布后续问题。

很高兴为您提供帮助！
