为邮件正文 PHP 输入新行

【问题标题】：Enter new line for mail body PHP为邮件正文 PHP 输入新行
【发布时间】：2019-12-27 05:53:25
【问题描述】：

我对邮件正文的“输入”有疑问。我使用 textarea 作为表单中的输入，然后将其提交以通过 gmail 发送。问题是，正文总是有“\r\n”而不是“输入”。我尝试了许多建议，例如 nl2br、trim 等，但仍然无法正常工作。

这是我的代码：

这是表格

<?php
session_start();
$user_id = $_SESSION['id'];
include 'config.php';
$tabel = mysqli_query($mysqli, "SELECT * FROM tabel WHERE id=".$_GET['id']."");
$row = mysqli_fetch_array($tabel);
$name = $row['name'];
$getname = $mysqli->query("SELECT * FROM list_email WHERE name = '$name'");
$row2 = $getname->fetch_array();
$id = $_GET['id'];
?>

【问题讨论】：

  • 我通常使用&lt;br/&gt;，我知道这是一个黑客，但它对我来说就像这样echo "Hello World &lt;br/&gt; World Hello";
  • 您是在创建 HTML 电子邮件还是简单的文本电子邮件？
  • 如果您尝试发送 HTML 电子邮件，请检查 w3schools.com/php/func_mail_mail.asp 如果您直接从 textarea 发送数据，也将换行符 \n 替换为
    标签。如果您是文本编辑器，则无需将换行符更改为
  • 对不起，它仍然无法与您合作 isHTML(true)
  • 我正在使用 phpmailer 通过 gmail 发送电子邮件。我使用 google oauth 登录，关于邮件，它来自我的表单

标签： php phpmailer newline


【解决方案1】：

试试类似的东西

echo mysqli_real_escape_string($mysqli, str_replace("\n","<br/>",$_POST['message']));

您只能在发送电子邮件时替换 \n，而不是在 textarea 中。

或

在 PHPMailer 中，$mail-&gt;isHTML(true); // 将电子邮件格式设置为 HTML

查看更多信息： Sending emails with PHPMailer

【讨论】：

  • 嗯，如何放置 echo 语句？
  • @AdityaVictory Write $message = mysqli_real_escape_string($mysqli, str_replace("\n","
    ",$_POST['message']));
【解决方案2】：

您可能以 HTML 格式发送电子邮件，而您的文本区域包含普通文本。您应该用&lt;br/&gt; 标记替换换行符（\r\n 或\n）。你可以使用：

$emailBody  = str_replace(["\r\n", "\n"] , "<br/>", $emailBody);
//OR
$emailBody = nl2br($emailBody);

对于 nl2br，请参阅documentation

【讨论】：

  • 为什么在 str_replace 中使用方括号？
  • 我可以简单地做str_replace("\n" , "&lt;br/&gt;", $emailBody)，但我想用
    替换 \r \n 和 \n 会更清楚。不是吗？
  • 我已经按照类似问题的建议尝试了 replace 和 nl2br ，但这些对我的情况不起作用。我不知道，如果我把它放在变量中，也许“\n”只是读为纯文本而不是“输入”？
  • 将 \n 替换为
    结果相同，除了
    在文本区域和邮件正文中都可见
