It looks like you're having a similar problem to this.

看起来你也有类似的问题。

If I'm reading correctly, try:

如果我读的正确，试试:

<textarea>{$content|stripcslashes}<textarea>

#2

I'm no Smarty guru, but you might want this in your template instead:

我不是Smarty guru，但是您可以在模板中使用这个:

<textarea>{$content|stripslashes}<textarea>

#3

This replaces all \r\n with \n.

这将取代所有的\ \n和\n。

$content = str_replace("\r\n", "\n", $content);

I have used that successfully a couple of days ago, and they come out correctly in a text field.

几天前，我成功地使用了它，它们在文本框中正确地显示出来。

#4

I had the same problem with the \r\n, but I had to add extra backslashes to the search argument (i.e., \r\n becomes \\r\\n) to make it work:

我也有同样的问题，但是我必须在搜索参数中添加额外的反斜杠。，\\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\

$content = str_replace("\\r\\n","\r\n",$content);

$ = str_replace内容(“\ \ r \ \ n”,“\ r \ n”,美元内容);
