line breaks

[The Little Guy]

I have the following method:

	public function format($text){
	$text = preg_replace("~\[intro\](.*?)\[\/intro\]~si", "<h3>Introduction</h3>$1", $text);
	$text = preg_replace("~\[links\](.*?)\[\/links\]~si", '<h3>Links</h3>'.$this->setLinks("$1"), $text);
	$text = preg_replace("~\[qs\](.*?)\[\/qs\]~si", "<h3>Quick Steps</h3><pre>$1</pre>", $text);
	$text = preg_replace("~\[title=(.*?)\]~si", "<h3>$1</h3>", $text);
	$text = preg_replace("~\[img=(.+?)\]~si", "<a href=\"/images/dspl/$1\"><img src=\"/images/dspl/$1\" /></a>", $text);
	$text = nl2br($text);
	return $text;
}

 

I have nl2br, but there are some areas where I don't want to use it, such as between and after the "qs" tags, after the "title" tags, and after the "intro" tags.

 

How can I do that?

function br2nl($string)

{

    return preg_replace('/\<br(\s*)?\/?\>/i', "\n", $string);

}

 

That should simplify it for yah

Why not trim or remove newline entities from the text you don't wish to be converted to <BR>?

Why not trim or remove newline entities from the text you don't wish to be converted to <BR>?

 

How would I do that with my current code?

[ChemicalBliss]

use concatenation on the replacement valuies for the tags you _do_ want a <br> after:

 

	public function format($text){
	$text = preg_replace("~\[intro\](.*?)\[\/intro\]~si", "<h3>Introduction</h3>$1", $text);
	$text = preg_replace("~\[links\](.*?)\[\/links\]~si", '<h3>Links</h3>'.$this->setLinks("$1"), $text."<BR/>");
	$text = preg_replace("~\[qs\](.*?)\[\/qs\]~si", "<h3>Quick Steps</h3><pre>$1</pre>", $text);
	$text = preg_replace("~\[title=(.*?)\]~si", "<h3>$1</h3>", $text);
	$text = preg_replace("~\[img=(.+?)\]~si", "<a href=\"/images/dspl/$1\"><img src=\"/images/dspl/$1\" /></a>", $text)."<BR/>";
	return $text;
}

That doesn't work.

In the preg_replace, you can match the newline character (the ones you don't want replaced), then replace it with some dummy text, but make it distinct. Something like {LINE_BREAK}.

 

Then after nl2br, replace {LINE_BREAK} with the newline character.

[The Little Guy]

Am I doing this correctly? I cant get it to work...

 

	public function format($text){
	//$text = nl2br($text);

	$text = preg_replace("~\n~", "{LINE_BREAK}", $text);
	$text = preg_replace("~\[intro\](.*?)\[\/intro\]~si", "<h3>Introduction</h3>$1", $text);
	$text = preg_replace("~\[links\](.*?)\[\/links\]~si", '<h3>Links</h3>'.$this->setLinks("$1"), $text);
	$text = preg_replace("~\[qs\]({LINE_BREAK})\[\/qs\]~si", "\n", $text);
	$text = preg_replace("~\[qs\](.*?)\[\/qs\]~si", "<h3>Quick Steps</h3><pre>$1</pre>", $text);
	$text = preg_replace("~\[title=(.*?)\]~si", "<h3>$1</h3>", $text);
	$text = preg_replace("~\[img=(.+?)\]~si", "<a href=\"/images/dspl/$1\"><img src=\"/images/dspl/$1\" /></a>", $text);
	$text = preg_replace("~{LINE_BREAK}~s", "<br />", $text);
	return $text;
}

[Ken2k7]

No, no. You need to be specific. You said you don't want it replace in between the qs tag and after it. Just focus on those special cases. After that, run it through nl2br. It'll put breaks in all places except those you don't want because you replaced those values. After you run it through nl2br, then you change {LINE_BREAK} back tot he new line character.

[The Little Guy]

I still can't get it.

 

how can I replace ONLY new lines between the qs tags?

[The Little Guy]

I just used the e modifier:

 

$text = preg_replace("~\[qs\](.*?)\[\/qs\]~sei", "'<h3>Quick Steps</h3><pre>'.stripslashes(str_replace('<br />', '', '$1')).'</pre>'", $text);
