Remove linebreaks in text with what function?

Worker Joined: Apr 26, 2005 Posts: 114

I'm trying to replace the linebreaks found in nuke_bbposts_text.

My question is:
What are the linebreaks found in nuke_bbposts_text?
Is str_replace the right thing to use?

$message = str_replace("Linebreaks_in_bbposts", "<br>", $message);

Can you clarify the problem and exactly what you are trying to achieve? I not sure why you would want to remove line breaks as text and other functions would all run together making things more difficult to read.

My neverending problem, i'm sorry...It's so d*** hard to explain in good english (i'm norwegian).

I'm trying to pull the text from nuke_bbposts_text, and let the selected (corresponding to the first post in each thread). Next step is to convert the text (with BBcode, linebreaks, etc....) so that overLIB can use it in javascript. (part of the problem seems to be the linebreaks, overLIB will not process them)
Finally the result will show up as a tooltip-box over each thread-link so the user can determine some of the content before entering the thread itself.

The idea is based on OnMouseOverTitle-mod from http://www.phpbbhacks.com/download/3691 ...but i belive what i'm trying to achive here is a bit more complicated...and maybe useful...

Why not try to use an XML/RSS "backend.php" type function to extract and summarize the data and then use an RSS block to post it back? This way you don't have to worry about breaks and code.

Beacuse I haven't got a clue how to do that... Embarassed

BTW, i found the linebreaks...

Code:

\r\n

I have this thingy working 90% now, I was hoping to get it at least 99%. Not saying xml/rss is a better way, it's just that I don't even know where to begin...

*lol* Guess some of you getting a good laugh at this, but i'll post it anyway...This is my strip-text-function so far:

Code:

function bbencode_strip($message, $uid)


{


   $message = strip_tags($message);   


   $message = str_replace("[url]","", $message);


   $message = str_replace("[url=","", $message);


   $message = str_replace("[/url]", "", $message);


   $message = str_replace("[img]","", $message);


   $message = str_replace("[/img]", "", $message);


   $message = str_replace("[color=","", $message);


   $message = str_replace("[/color]","", $message);


   $message = str_replace("'", "”", $message);


   $message = str_replace('"', "”", $message);


   $message = preg_replace("/\[url=([a-z0-9\-\.,\?!%\*_\/:;~\\&$@\/=\+]+)\]/si", "", $message);


   $message = preg_replace("/\[img=([a-z0-9\-\.,\?!%\*_\/:;~\\&$@\/=\+]+)\]/si", "", $message);


   $message = str_replace("[/url:$uid]", "", $message);


   $message = preg_replace("/\[.*?:$uid:?.*?\]/si", '', $message);


   $message = preg_replace('/\[url\]|\[\/url\]/si', '', $message);


   $message = str_replace("\r\n", "<br>", $message);


   return $message;


}

This code is from a similar Mod mentioned over, but made/modified:

I know the replacements are far from perfect, but at least I got myself a hobby for some days Very Happy

Looks good!

That would have been my suggestion for replacing the linebreaks...

If you simply want to get rid of them, I'd use this:

Code:

    $message = rtrim($message, " \r\n ");

It seems Only registered users can see links on this board! Get registered or login! can process br-tags, so i'll primarily keep them. Looks better on the tooltip.

The headache is how to remove all the BBcode before processing further.

Why not just use

Code:

$message = nl2br($message);

I'm not sure at all why, but

Code:

$message = nl2br($message);

does not work with my script at all.

There was still some bugs with the previeously \r\n, but I found a more robust replace:

Code:

$message = preg_replace("/(\r\n|\n|\r)/", "", $message);

Why it works in a different way, I don't know. I got rid of the remaining bugs with the line breaks.

Still got an issue with the line breaks in

Code:

'TOPIC_TITLE' => $topic_title,

(found in viewforum.php)

Usually, there's no line breaks in the forumtitle, but in a few imported rss-feeds, the title contains line breaks (don't ask how or why, it's not br-tags, neither are any line breaks shown in phpMyAdmin...only visible in the browsers "view source")

Since javascript will read ' as a part of the script-code i had to remove them. I'm now trying to remove line breaks in forumtitle as well:

Code:

'TOPIC_TITLE' => $topic_title = preg_replace("/(\r\n|\n|\r|')/", "", $topic_title),

Without any luck....a few linebreaks remain in forumtitle...

nl2br() translates all newline characters to <br /> tags. See http://us3.php.net/manual/en/function.nl2br.php. To say it doesn't work at all is very strange. What I meant was to replace this one line

Code:

$message = str_replace("\r\n", "<br>", $message);

with

Code:

$message = nl2br($message);

Well, it'd probably work, if it wasn't for the \r It seems to replace all the rest.

Anyways, the use of nl2br as suggested, did not work in my case.

I'll make an effort to post the whole thing tomorrow, if any want to try this out themselves.

Heh! I love watching this process take place!

I attacked 'str_replace', 'preg_replace', 'rtrim', et cetera, on my own, in the middle of the night, so to speak. I felt so alone, but at the same time, so empowered.

I can see all this unfolding in you as well, simply by watching your 'thinkings' take place, as expressed in this thread. Basically, you're 'talking' out loud, but that's okay.

If it's of any consolation, you are getting a handle on 'it'. Hang in there!

LOL, thanks VinDSL
And you are right, mostly i do 'think loud' here. None of my friends IRL has knowledge of either php, nuke or sql, so i guess it's better to think loud here, instead of all-by-myself. And the answers you all are giving, makes a difference from other forums, where newbies often gets a negative respons.
