Question

I am using <pre> tags to preserve long strings of text that include user-entered line breaks.

When the input into the original form was exactly:

Paragraph 1

Paragraph 2

Paragraph 3

…the pre returns:

            Paragraph 1

     Paragraph 2

     Paragraph 3

In the database, the string is stored:

"Paragraph 1\r\n\r\nParagraph 2\r\n\r\nParagraph 3."

1. Why is this happening?
2. If the best way to get around this to simply strip out all leading spaces from every newline, how can I accomplish this so it happens across the entire site?

Edit: I’m using Ruby on Rails – what would be the code in that case? A particular problem I’m having is with a HAML page.

%pre
  - unless condition.blank?
    %br
    - unless @user.show_notes == false
      :preserve
      #{@user.notes}

Answer 1

You’re probably indenting your code, eg (PHP example)

<pre>
    <?php echo $myString ?>
</pre>

Notice the space before the opening <?php tag?
