如何将邮件发送到我的数据库表中的所有电子邮件？

Question

我尝试使用此代码向具有相同类别的人发送电子邮件。

if ($action = 'message_til_flere') {
        $vagt_ansat_email = $_POST['vagt_ansat_email'];

        $select_alle_mails = " SELECT vagt_ansat_email FROM vagt_ansat_med_kategori WHERE vagt_kategori_id = $id ";

        $til_vagter = array();
        while ($row = mysql_fetch_array($select_alle_mails)) {
            $til_vagter[] = $row['vagt_ansat_email'];

        $to = $til_vagter;

        $subject = "E-mail subject";
        $headers = 'From: mywebpage' . "\r\n";
        $headers .= 'Reply-To: mywebpage' . "\r\n";
        $headers .= 'BCC: ' . implode(', ', $til_vagter) . "\r\n";
    }
         mail($to, $subject, $headers);

Answer 1

$ to不能是一个数组。它必须是一个字符串。多个mailadresses必须以逗号分隔。为此，您可以使用php函数implode

$to = implode(',', $til_vagter);

示例：

if ($action = 'message_til_flere') {
    $vagt_ansat_email = $_POST['vagt_ansat_email']; // never used in this part

    $select_alle_mails = " SELECT vagt_ansat_email FROM vagt_ansat_med_kategori WHERE vagt_kategori_id = $id ";

    $til_vagter = array();
    $result = mysql_query($select_alle_mails); // a connection to db is required
    while ($row = mysql_fetch_array($result)) { // fetch results as array
        $til_vagter[] = $row['vagt_ansat_email'];
    }

    $to = "myemailadress@mywebsite.tld";

    $subject = "E-mail subject";
    $headers = 'From: mywebpage' . "\r\n";
    $headers .= 'Reply-To: mywebpage' . "\r\n";
    $headers .= 'BCC: ' . implode(', ', $til_vagter) . "\r\n";
    $message = "Test Body";

    mail($to, $subject, $message, $headers); // a message is required
}

Answer 2

我个人会在循环中一次发送一封邮件，如下所示：

if ($action = 'message_til_flere') {
 //   $vagt_ansat_email = $_POST['vagt_ansat_email']; //not used?

    $select_alle_mails = " SELECT vagt_ansat_email FROM vagt_ansat_med_kategori WHERE vagt_kategori_id = $id ";

    //RUN QUERY
$sel_result = mysql_query($select_alle_mails); 

    while ($row = mysql_fetch_array($sel_result)) {


    $subject = "E-mail subject";
    $headers = 'From: mywebpage' . "\r\n";
    $headers .= 'Reply-To: mywebpage' . "\r\n";
     $message="dear bob, having fun?";
     mail($row['vagt_ansat_email'], $subject, $message, $headers);
 }

您在获取之前未执行查询，并且您将查询字符串传递给mysql_fetch_array()，这是不正确的。它是您需要获取的查询的结果：

    $select_alle_mails = "SELECT vagt_ansat_email 
                          FROM vagt_ansat_med_kategori 
                          WHERE vagt_kategori_id = $id ";

    $result = mysql_query($select_alle_mails);
    $til_vagter = array();
    while ($row = mysql_fetch_array($result)) {...}

• mysql_已弃用
• 使用预备陈述
• 我不确定mail()是否对收件人有限制，但听起来应该是批量发送
