Question

我正在开发一个php脚本，它收集以html格式输入的数据并将该数据存储在数组中。当用户按下提交按钮时，调用php脚本以捕获数组中的数据存储并保存到CSV文件中，如果所有这些都很顺利，则会有一个标题（位置：''）重定向到确认页面。

现在，我还要向注册的用户发送一封确认电子邮件，我所做的是创建了一个文件template.php，它有一个很好的html模板，我添加了一个mail（）函数来实现。

但是我收到一个错误说：

19th February 2014 Warning: Cannot modify header information - headers already sent by (output started at /home/content/24/12131124/html/php/template.php:36) in /home/content/24/12131124/html/php/form_to_csv.php on line 196

template.php：

<?php

function getMailContent(){

$subject = "OPES Academy- Workshop confirmation";
$message = "

    //mail($to, $subject, $message, $headers,"-f info@opesacademy.com");
  mail($to, $mailContent['subject'], $mailContent['message'], $mailContent['headers'],"-f info@opesacademy.com");


}

    if(@$_POST['land']=='fw')header("Location: http://www.o.com/free/b/confirmation.php?camp=".$data['camp']);
    else header("Location: http://www.o.com/free/f/confirmation.php?camp=".$data['camp']);

所以看看错误，我理解标题存在某种问题，因为mail（）函数都使用标题，在重定向我使用标题，但如何解决为什么这是一个问题..？

Answer 1

这与template.php中的echo有关。你想连接（句点）而不是echo。如果您回显，则表示您正在开始输出，因此无法在以后编辑标题信息。

Answer 2

根据您的要求，我认为应该是这样的：

<?php
require('helper.php');

function getMailContent(){

$subject = "OPES Academy- Workshop confirmation";
$message = "
<body style='background-color: #eeeeee; margin: 0 auto; font-family: 'lato',sans-serif'>

// ... Blah Blah Blah   
// ...looking forward to see you at the";

 $message .= ConvertDate( $_SESSION['date'] );                  
 $message.="            
                    <p align='center'>Address: 6 Thomas More Square, London, E1W 1XZ</p>

 //... Blah Blah Blah   

</body>";

//... Rest of the code...

?>

Answer 3

为什么函数中包含以下代码？

<?php
    require('helper.php');
    echo ConvertDate( $_SESSION['date'] );
?>

您不能echo进入$message，因为回显是指发送给用户浏览器的内容（正如迈克尔所说）。

尝试$message .= ConvertDate( $_SESSION['date'] );
