Question

我正在尝试通过PHP发送电子邮件，其中正文依赖于几个if语句。

我知道你不能在mail（）函数中调用if语句，所以我想知道是否可以在多个变量中声明正文项，然后将它们调用到mail（）体中

到目前为止我所拥有的内容如下，但我确信你可以猜到，它不起作用，真的很感激一些反馈。

if (!empty($phone)) {$email_phone = echo 'Phone Number: ' $phone \r\n};
        mail('email@domain.com', 'New Visitor Information', "Hello Pastor,\r\n\r\nWe had a new visitor on " . $visit_date . "\r\n\r\nTheir Details:\r\n\r\nName: " . $first_name . " " . $last_name . "\r\n" . $email_phone . " ");

Answer 1

试试这个

<?php
    if (!empty($phone)) {$email_phone = "Phone Number: ".$phone; };
            mail('user@domain.com', 'New Visitor Information', "Hello Pastor Steve,\r\n\r\nWe had a new visitor on " . $visit_date . "\r\n\r\nTheir Details:\r\n\r\nName: " . $first_name . " " . $last_name . "\r\n" . $email_phone . " ");

            ?>

Answer 2

if (!empty($phone)){

    $email_phone = "Phone Number: " . $phone . "\r\n";
    $email = "email@domain.com";
    $subject = "New Visitor Information";
    $body = "Hello Pastor,\r\n\r\nWe had a new visitor on " . $visit_date . "\r\n\r\nTheir Details:\r\n\r\nName: " . $first_name . " " . $last_name . "\r\n" . $email_phone . ";

    mail($email, $subject, $body)

};

这样，只有有电话号码值才会发送邮件。

Answer 3

首先建立身体，然后发送它：

$body = 'Hello, world';
if ($some_condition) {
   $body .= " blah blah blah";
}
if ($other_condition) {
   $body .= "blah blah blah";
}
mail(....);

Answer 4

我总是这样做：

$mailTo = "steve@domain.com";
$subject = "New Visitor Information";

$message=array();
$message[] = "Hello Pastor Steve,";
$message[] = "";
$message[] = "We had a new visitor on " . $visit_date;
$message[] = "";
$message[] = "Their Details:";
$message[] = "";
$message[] = "Name: " . $first_name . " " . $last_name;
$message[] = "";

if (!empty($phone)) {
    $message[] = "Phone Number: " . $phone;
}

$message = implode("\r\n", $message);

mail($mailTo, $subject, $message);

我使用数组来连接一些字符串。这比使用点运算符连接字符串要快得多。因此它的格式更清晰，因此您可以更清楚地发现空行。现在，您可以看到如何使用if子句和变量。
