Converting certain newlines to <br />s

[Christopher Finke]

I have a site wherein the clients can update the individual pages by editing
the text of that page in a <textarea>. Then, when the page is displayed,
all of the newlines (\n) are converted to HTML line breaks (<br />).
However, I have come across some instances where I do not want to convert
the newlines, such as the following:

<table>
<tr>
....
</tr>
</table>

Obviously, I would not want this to be

<table><br />
<tr><br />
....
</tr><br />
</table><br />

Can anyone suggest a method for achieving this? I've tried different
mixtures of regular expressions, but my skills with those are just not up to
par.

Christopher, first off it's never a good idea to allow people to enter html
code in forms of a content management service. You can allow them to insert
simple tags like <i>,<b> and <u> but if you're allowing them to create
things like tables it could seriously screw up the design of the site.

A practical solution for your problem would be to do a str_replace on the
text before you store it. For example:

$remove = array("<table>\ n", "<table>\r" , "<table>\r\ n");
$text = str_replace($re move, '<table>', $text);

see: http://www.php.net/str_replace

Hope it helps,

Well, depending on how much work you want to do, which wouldn't be all
that much really, you could let them put tables in providing that you
check the syntax, running it through PHP's XML Parser actually may do
the trick, in the effort to make sure for every opening tag we have a
closing tag because tables are only really a pain in that scenario if
they close and don't open or such like.

I think that if you let them write <table> etc tags, they should be
aware of the fact that newlines don't show up the way they expect it
too.

If you use output buffering, you could run tidy before outputting the
lot.

It can't be done. You either accept HTML as input or accept plain text. Your
computer can't resolve the ambiguity when you mix the two up.
