Question

我正在尝试将所有电子邮件放入数组并按$_SESSION发送数组，然后向他们发送一封电子邮件。

$getData = $db->prepare('SELECT id,institute,section,name,sudImage,email FROM enrollment_student WHERE institute=? AND section=?');
$getData->bind_param('ii', $insId, $vEnSt);
if ($getData->execute()) {
    $getDataResults = $getData->get_result();
    while ($es = $getDataResults->fetch_array()) {

        $sendEmailToAll = array($es['email']);
        $_SESSION['eta'] = $sendEmailToAll;

        $getUrl = 'http://' . $_SERVER['SERVER_NAME'] . $_SERVER['REQUEST_URI'];
        $_SESSION['efaUrl'] = $getUrl;

        print_r($_SESSION['eta']);

print_r($_SESSION['eta']);的结果是Array ( [0] => email@hostnile.com ) Array ( [0] => email@hotmail.com )

但在另一页上：

$subject = $_POST['subject'];
$message = $_POST['message'];

$recipient = $_SESSION['eta'];
$efaUrl = $_SESSION['efaUrl'];

print_r($_SESSION['eta']);

mb_internal_encoding("utf-8");
$subjectText = $subject;
$subject = mb_encode_mimeheader($subjectText, "UTF-8");
$content = '<html><body>';
$content = '<head><meta http-equiv="Content-Type" content="text/html; charset=utf-8"/></head>';
$content .= $message;
$content .= '</html></body>';

$headers = 'From:admin@academyofart.com' . "\n";
$headers .= "MIME-Version: 1.0\n";
$headers .= "Content-Type: text/html; charset=UTF-8\n";

$reTravel = mail($recipient, $subject, $content, $headers);
if ($reTravel == true) {
    //header('Location:' . $efaUrl . '&m=s');
    echo "Done";
} else {
    //header('Location:' . $efaUrl . '&m=f');
    echo "Error";
}

尝试print_r同一$_SESSION['eta']来Array ( [0] => email@hotmail.com，因为只有一封电子邮件，结果也会echo "Error";发送Error。

我做错了什么？提前致谢

Answer 1

你要覆盖会话变量'eta'，试试这个

$_SESSION['eta'][] = $sendEmailToAll;

Answer 2

注意：所有传入的数据都应该经过验证和消毒！无处不在！的

应该修复第一个脚本：

-- remove this two lines
$sendEmailToAll = array($es['email']);
$_SESSION['eta'] = $sendEmailToAll;

-- insert this instead of removed
$_SESSION['eta'][] = $es['email'];

第二个脚本更改：

$subject = $_POST['subject'];
$message = $_POST['message'];

$efaUrl = $_SESSION['efaUrl'];

mb_internal_encoding("utf-8");
$subjectText = $subject;
$subject = mb_encode_mimeheader($subjectText, "UTF-8");
$content = '<html><body>';
$content = '<head><meta http-equiv="Content-Type" content="text/html; charset=utf-8"/></head>';
$content .= $message;
$content .= '</html></body>';

$headers = 'From:admin@academyofart.com' . "\n";
$headers .= "MIME-Version: 1.0\n";
$headers .= "Content-Type: text/html; charset=UTF-8\n";

foreach ($_SESSION['eta'] as $recipient) {

    // I would like to recommend add the last parameter
    // otherwise some of email-servers detect your email as spam   
    $reTravel = mail($recipient, $subject, $content, $headers, '-fadmin@academyofart.com');

    // notice: it will print Done or Error for every email
    if ($reTravel == true) {
        //header('Location:' . $efaUrl . '&m=s');
        echo $recipient.": Done".PHP_EOL;
    } else {
        //header('Location:' . $efaUrl . '&m=f');
        echo $recipient.": Error".PHP_EOL;
    }
}

将来自数据库的所有电子邮件放入阵列，然后向他们发送电子邮件
