What is wrong with prettify?

I'm using prettify on my blog to be able to paste code.

In functions.php I have the following code to make the code clean (the < code> tags without spaces off course):

function bbcode( $attr, $content = null ) {

        $content = clean_pre($content); // Clean pre-tags

        return '<pre class="prettyprint">< code>' . str_replace('<', '&lt;', $content) . '< /code></pre>';

    }

    add_shortcode('kod', 'bbcode');

So when I'm pasting code in my posts, I'm doing inside a shortcode, like this:

[kod]Some code[/kod]

So far, so good, and prettify works pretty well, accept that sometimes I'm getting weird line-breaks.

When pasting this code:

<?php if ($col == 1) echo '<div class="rad">'; ?>

This is what I'm getting:

<?php if ($col == 1) echo '

<div class="rad">'; ?>

Can someone point me in the right direction to why this is happening? You can see an example post here:

http://webbhjalp.se/wordpress-inlagg-kolumner/

Notice that on all code examples where I'm trying to echo a <div> I'm getting line breaks.

If I'm manually changing <div to <div it works as it should, but the function I'm using is also doing this, so I can't understand what's happening!

Thanks!

// Jens.

Hi Jens,

Maybe some filter is doing it. Try to unable all them:
```
add_action( 'all', create_function( '', 'var_dump( current_filter() );' ) );
```

  If there's no problem with other tags, something has to be in the middle.

  Jens,
  
  From: 5 ways to debug WordPress
  
  There’s an ‘all’ hook that fires for all actions and filters. Example usage:
  
  add_action( 'all', create_function( '', 'var_dump( current_filter() );' ) );
  You’ll be surprised how many hooks get executed on every page load. Good for troubleshooting and identifying the right hook.
  
  There’s also a ‘shutdown’ hook you can use in combination with, say, SAVEQUERIES, and write the query information to the database. It’s the last hook to run.
  
  I have to go out, later I continue.

  Look at it: WordPress: Disable Auto Paragraphing, wpautop() and clean_pre() Functions
  
  It seems that clean_pre() is introduce autoparagraph. With this code you can solve it.

  Unfortunately that didn't work. And looking at the generated source, there are no p or br tags either... Only weird thing is a single space (sp ace), which I can't find where it's coming from!

Ummm, yesterday in shortcodes I solved similar problem with

 $content = str_replace('<br />', '', $content);

How do I add that to my function then?

Julius J. says:

function bbcode( $attr, $content = null ) {

 

        $content = str_replace('<br />', '', $content);

        $content = clean_pre($content); // Clean pre-tags



        return '<pre class="prettyprint">< code>' . str_replace('<', '&lt;', $content) . '< /code></pre>';



    }



    add_shortcode('kod', 'bbcode');

Simple as that.

She Codes says:
```
<span class="str">' &lt;div class="rad"&gt;'</span>
```
This is the source code from your site.
There is no break, there is a space there - between the ' and <

Are you sure this space character does not come from your function or from the text in the post?

  Jens Filipsson says:
  Yes, I saw that as well! It's weird, but it still shouldn't force a line break I reckon?

  This is by no means the best way to do this, but it is the quickest way I could think of to check if clean_pre is adding the break. Please try this instead of your function (the < code> tags without spaces off course):
```
function bbcode( $attr, $content = null ) {

	$content = str_replace('<', '&lt;', $content);

	$content = str_replace('>', '&gt;', $content);

	$content = str_replace('&lt;p&gt;', '<p>', $content);

	$content = str_replace('&lt;/p&gt;', '</p>', $content);

	$content = str_replace('&lt;br /&gt;', '<br />', $content);

	

	$content = clean_pre($content); // Clean pre-tags

	return '<pre class="prettyprint">< code>' . $content . '< /code></pre>';

}



add_shortcode('kod', 'bbcode');
```

  No difference I'm afraid :(

  One last idea from me:
```
function bbcode( $attr, $content = null ) {



        $content = clean_pre($content); // Clean pre-tags



        return '<pre class="prettyprint">' . $content . '< /code></pre>';



}

add_shortcode('kod', 'bbcode');

                  
```
