Dynamic meta description tag generation fix

[creep]

Not sure if this is the right place, but since original truncate_content() function don't doing all necessary "truncate" and often outputs html meta description tag in wrong way i consider this a bug and would like to share my fix with the community:

Found truncate_content() function in /libs/link.php

     function truncate_content(){
        $TruncatedContent = substr($this->content, 0, StorySummary_ContentTruncate);
        if(strlen($this->content) > StorySummary_ContentTruncate){$TruncatedContent .= "...";}
        return $TruncatedContent;
    } 
  

and replace it with this new one:

     function truncate_content(){

        $TruncatedContent = htmlspecialchars($this->content);
        $TruncatedContent = preg_replace('/\s+/', ' ', trim($TruncatedContent));

        if(strlen($TruncatedContent) > StorySummary_ContentTruncate) {
        // Set the replacement for the "string break" in the wordwrap function
        $cutmarker = "**cut_here**";
        // Using wordwrap() to set the cutmarker
        // NOTE: wordwrap (PHP 4 >= 4.0.2, PHP 5)
        $TruncatedContent = wordwrap($TruncatedContent, StorySummary_ContentTruncate, $cutmarker);
        $TruncatedContent = explode($cutmarker, $TruncatedContent);
        $TruncatedContent = $TruncatedContent[0] . "...";
        }
        return $TruncatedContent;
    } 
  

After this the meta description tag will be generated in right way.

Enjoy!

What's wrong with the current output of the description meta tag?

If your story description has new lines, the description tag looks like:

<meta name="description" content="blabla

newline was there..." />

It should look like

<meta name="description" content="blabla &lt;br /&gt; &lt;br /&gt;newline was there..." />
