Question

所以我有一个系统，你可以在其中添加成员到你的组，电子邮件似乎发送完全没有所有信息，但我收到一个错误，说明$ body是一个未定义的变量，任何建议？

   <?php //check member Email matches
$addmember = $link->query("SELECT Email FROM logins WHERE Email ='$memberemail'")->fetch_assoc()['Email'];


$to = $addmember;
$subject = "Becoming part of $leaguename";
            $body.="So you want to become part of $leaguename?".PHP_EOL;
            $body.="Please click the link below to join!".PHP_EOL;
            $body.="http://www.wesbitelink.dev/verify.php?memberemail=$memberemail;".PHP_EOL;

            $headers = "From: localhost";

            mail($to, $subject, $body, $headers);
          header("location: addanothermember.php");

  ?>

我收到的错误消息是：

Notice: Undefined variable: body

Answer 1

首先在你可以在这个变量上附加东西之后创建$ body变量

 <?php //check member Email matches
$addmember = $link->query("SELECT Email FROM logins WHERE Email ='$memberemail'")->fetch_assoc()['Email'];


$to = $addmember;
$subject = "Becoming part of $leaguename";
            $body="So you want to become part of $leaguename?".PHP_EOL;
            $body.="Please click the link below to join!".PHP_EOL;
            $body.="http://www.wesbitelink.dev/verify.php?memberemail=$memberemail;".PHP_EOL;

            $headers = "From: localhost";

            mail($to, $subject, $body, $headers);
          header("location: addanothermember.php");

  ?>

试试这个

Answer 2

这是因为您在.=之前$body上使用$body已定义。将第一个.=更改为仅=或之前定义$body。

请参阅http://php.net/manual/en/language.operators.string.php

中有关字符串运算符的手册

电子邮件发送正常，但我收到消息$ body未定义？
