CakePHP sanitize line feed \n

Question

I have a comment box and when somebody presses enter, Cake will put a \n (line feed) into the database. When I retrieve this from the db, it is displayed just like \n instead of an actual break or in HTML a
.

There seems to be no option for handling \n, which I cannot understand because it is common to push enter in a textarea. What am I doing wrong?

Thanks Chris

Answer 1

CakePHP has it's own method for that:

TextHelper::autoParagraph(string $text)

Check the documentation: https://book.cakephp.org/2.0/en/core-libraries/helpers/text.html

Answer 2

You can also try echo str_replace("\\n", "<br />", $variable);

Answer 3

you forget that there are php functions covering that :) nl2br() is what you are looking for

echo nl2br(h($data));

NOTE:

• h() is for security reasons. always use h() first, than nl2br().

• you dont need h() if you have html content. h() is only for plain text.

• TIP: you can even enhance your bake templates to automatically display it correctly - see http://www.dereuromark.de/2010/06/22/cake-bake-custom-templates/ for details
