PHP的 - 表格邮件转换线断裂到空格 [英] PHP - Form mail converting line breaks to spaces

问题描述

在用户注释的表单中有一个< textarea> ，并且当内容传递给表单邮件时，换行符被转换为空格。如何保留表单用户输入的换行符？

相关php：

  $ comments = $ _REQUEST ['comments']; 
 //这会从提交的表单中获取注释
 
 // ... 
 
 $ to = $ configEmail; 
 
 $ subject =收到的网站订单：$ offer; 
 
 $ contents =blah blah blah ...; 
 if（！empty（$ comments））{
 $ contents = $ contents。\\\
Comments：$ comments\\\
\\\
; 
} 
 
 // ... 
 
邮件（$ to，$ subject，$ contents）; 
  

并且在表单的HTML结尾处...（如果它是数据不会丢失）

 < label>评论/问题< / label> 
< textarea name =comments><？php echo $ comments; ？>< / textarea的> 
  

如果我输入：

 第1行
第2行
第3行
  

它仍然是这样的，如果表单提交时有错误，那么 $ comments = $ _REQUEST ['comments']; 肯定会保留换行符。但纯文本电子邮件给我：

 第1行第2行第3行$ b  

如何保留换行符？

解决方案

问题是来自textarea的换行符是 \\\
不是< br> ..
因此，在发送前用< br> 替换 \\\
邮件..

  $ body = str_replace（[enter]，\\\
，$ body）;

I have a <textarea> in a form for user comments, and when the contents are passed to form mail, the line breaks are being converted to spaces. How can I preserve the line breaks that the form's user types in?

relevant php:

$comments = $_REQUEST['comments'];
// This grabs the comments from the submitted form

//...

$to = $configEmail;

$subject = "Website Order Received: $offer";

$contents = "blah blah blah...";
if (!empty ($comments)) {
    $contents = $contents."\nComments: $comments\n\n";
}

//...

mail($to, $subject, $contents);

And in the HTML end of the form... (the comments are put into the form if it's submitted with errors, so data isn't lost)

<label>Comments / Questions</label>
<textarea name="comments"><?php echo $comments; ?></textarea>

If I type:

line 1
line 2
line 3

It remains like that if the form is submitted with errors, so $comments = $_REQUEST['comments']; is definitely preserving the line breaks. But the plain-text e-mail gives me:

line 1 line 2 line 3

How can I preserve the line breaks?

解决方案

The problem is the line breaks coming from the textarea are \n not <br>.. So replace the \n by <br> before sending the mail..

$body= str_replace("[enter]", "\n",$body);

Rember user double quoutes in "\n"...
