Question

我的$to变量是否必须等于这种情况下的某些内容，或者我的函数会自动填充该内容。

<?php

if (isset($_POST["MainCB"])) {
    $to = "test@test.com";
}
if (isset($_POST["ITCB"])) {
    $to = "test@test.com";
}
if (isset($_POST["CateCB"])) {
    $to = "test@test.com";
}
if (isset($_POST['submit'])) {
    $full_name = $_POST['full_name'];
    $MainCB = $_POST['MainCB'];
    $ITCB = $_POST['ITCB'];
    $CateCB = $_POST['CateCB'];
    $subject = "Form submission";
    $message = $full_name . " " . $MainCB . " " . $ITCB . " " . $CateCB;
    mail($to, $subject, $message);
    include 'mail.php';
}
?>

Answer 1

我建议阅读一些关于如何在PHP中发帖的文档，除了你想要完成什么？

if(isset($_POST["MainCB"]) || isset($_POST["ITCB"]) || isset($_POST["CateCB"])) {
  $to = "test@test.com"; 
}

将做同样的事情，更多if(isset($_POST['submit'])){应该总是等于true，实际上这应该是你最外面的if else语句。然后，您使用$to重写''变量，因此在没有用例之前删除其他代码。

代码是逻辑，阅读代码理解它并在需要时调整if else语句。

if(isset($_POST["MainCB"])){
  $to[] = 'mycustomemail@address.com';
}

if(isset($_POST["ITCB"])){
  $to[] = 'mycustomemail2@address.com';
}

if(isset($_POST["CateCB"])){
  $to[] = 'mycustomemail3@address.com';
}

if(!empty($to)){
  $to = array_unique($to); // remove duplicate entry's.
  foreach($to as $address){
    if(!filter_var($address, FILTER_VALIDATE_EMAIL)){
      die("'$address' is not a valid email");
    }
  }
  $to = implode(", ", $to);
} else {
  die('No addresses to send the mail to!');
}

现在$to将在mail()中使用1个字符串中想要的所有地址，但是应该考虑使用PHPMailer这样的库，但首先要关注编程的基础知识

根据您在评论和此问题中所说的内容：PHP send mail to multiple email addresses

您可以尝试这样的多个“to”：

<?php  

$recipients = array();

if(isset($_POST["MainCB"])) {
    $recipients[] = // one address email; 
}
if(isset($_POST["ITCB"])) {
    $recipients[] = // one other address email; 
}
if(isset($_POST["CateCB"])) {
    $recipients[] = // one more address email; 
}
if(isset($_POST['submit']) && !empty($recipients) ){ // You need to have at least one email address to sent it
    $to = implode(',', $recipients); // All your email address
    $full_name = $_POST['full_name'];
    $MainCB = $_POST['MainCB'];
    $ITCB = $_POST['ITCB'];
    $CateCB = $_POST['CateCB'];
    $subject = "Form submission";
    $message = $full_name . " " . $MainCB . " " . $ITCB . " " . $CateCB;
    mail($to,$subject,$message);
    include 'mail.php';
}
?>

这是你在找什么？

Answer 3

if(isset($_POST["MainCB"])) {
    $email = $email.  ", example@logs.uk.com";
}
if(isset($_POST["ITCB"])) {
    $email = $email. ", example@logs.uk.com";
}
if(isset($_POST["CateCB"])) {
    $email = $email. ", example@logs.uk.com";
}
$mail = $_POST["Email"];

在这种情况下，我的$ to变量是否必须链接
