问题

Question

我很难从一组复选框发送到选定的电子邮件地址的逻辑上。

我有一个简单的表单，只有一个名称和一个姓氏输入，以及4个复选框。

我想做的是选中一个复选框或选中多个复选框时，发送那些复选框代表的电子邮件。取决于选中哪个复选框仅发送到那些特定的电子邮件。

例如，我有4封电子邮件，并且是否选中了第一个复选框以发送到这些电子邮件。如果选中了复选框1和复选框2以发送给另一封电子邮件，或者选中了复选框2、3、4以发送给另一封电子邮件。

如果仅选中一个复选框，我的代码将正常工作。

如果我选中多个复选框（例如复选框1,3,4），它将仅将电子邮件发送到复选框1电子邮件，它将不会继续处理第三个复选框电子邮件或第四个复选框电子邮件。我会忽略它们。

希望有人可以帮助我解决这个问题。

谢谢。

这是我的PHP代码

问题

由于您使用else语句，因此迫使程序逻辑选择 this OR 那个，因此它将仅选择它发现的符合条件的第一个复选框，这是唯一的。

解决方案

重新设计代码，以便在所有有效实例中填充PHPMailer对象，然后按照表单数据（在此情况下为复选框）设置添加接收者：

if(isset($_POST['submit']) ){
    /***
     * Build mailer object with parts that are always true
     ***/

    $mail = new PHPMailer();
    $mail->setFrom($email);
    $mail->isHTML(true);
    $mail->Body = "
       <p><strong>Name:</strong> $name</p> 
       <p><strong>Surname:</strong> $surname</p>"; 

    /***
     * Check for IF clauses based on form data
     ***/
    if($_POST['cbone']) {
        $mail->addAddress("randomemailone@example.com");
        $mail->addAddress("randomemailtwo@example.com");
        ...etc....
    }
    if($_POST['cbtwo']) {
        $mail->addAddress("randomemailthree@example.com");
        ...etc....
    }
    if($_POST['cbthree']) {
        $mail->addAddress("randomemailthree@example.com");
        ...etc....
    }

    /***
     * finally, send mail
     ***/
    $mail->send(); 
}

这意味着您的代码现在检查所有条件，而不是仅检查第一个为真的条件。

我还建议您使用CSRF token来防止在页面刷新时重复发送电子邮件。另外，referenced by Synchro也请注意，clear PHPMailer addresses可以在发送前进行。

Answer 2

if语句的逻辑不正确。您正在执行此操作（使用伪代码）：

if (checkbox 1) {
  //send email 1
} elseif (checkbox 2) {
  //send email 2
} elseif (checkbox 3) {
  //send email 3
} elseif (checkbox 4) {
  //send email 4
}

将仅发送其中之一。如果要独立处理复选框的任何组合，则应按以下方式进行构造：

if (checkbox 1) {
  //send email 1
}
if (checkbox 2) {
  //send email 2
}
if (checkbox 3) {
  //send email 3
}
if (checkbox 4) {
  //send email 4
}

您不需要每次都创建一个新的PHPMailer实例；首先创建一个实例，设置所有实例共有的参数，然后对每个实例重新使用它，并在每次使用前用clearAddresses()清除地址列表。
