Preserving user-entered linebreaks


Posted on 16th Feb 2014 07:03 pm by admin

Hi, I'm building a web 2.0 thingy from scratch and I wanna display text which users input. It's all good so far, except that all the linebreaks are destroyed, so no matter how carefully they insert whitespace, their input gets displayed as one big block of text.

The data is submitted (method="post") through a textarea. The mysql_real_escape version is stored in mysql. Then it's read from the database (no unescaping necessary) and passed through htmlentities before being printed into the body of the webpage.

I tried replacing htmlentities with the following function:

Line number On/Off | Expand/Contractfunction brentities($x){ $x = str_replace("[LINEBREAK]","nr",$x); $x = str_replace("[LINEBREAK]","rn",$x); $x = str_replace("[LINEBREAK]","n",$x); $x = htmlentities($x); $x = str_replace("<pre>n</pre>","[LINEBREAK]",$x); return $x;}

But this doesn't seem to work. I also tried setting "white-space: pre;" in the CSS for the appropriate div, but that caused the text to bleed outside the div (and even outside the screen), so no go

What's the best way to settle this issue?

Thanks
