Forcing Capitalization with PHP

    global $smallwords, $capwords;
    $smallwords = array( 'a','of','the');
    $capwords = array('ALLCAPS', 'ABC', 'XYZ');

    $this->validfields['title'][VF_CODE] = '
        global $smallwords, $capwords;
        $retval = $dm->verify_title($data);

        $words = explode(" ", $data);
        foreach ($words as $key => $word) {
            $capword = strtoupper($word);
            if (in_array($capword, $capwords)) 
            {
                $words[$key] = $capword;
            }
            else if (!$key or !in_array($word, $smallwords)) $words[$key] = ucwords($word);
        }
        $data = implode(" " , $words);
        return $retval;
    ';
}

Wow what a helpful thread!! Thank you for posting this solution.

I have one question kh99 -- I have a lot of words that I would like to be left capitalized (lots of acronyms that are used on the forum). Is there a way I can have an external file in which I can enter the acronyms and have this plugin call that file rather than me having to add them all into the plugin code?

Thank you!

EDIT #1: Currently this code doesn't seem to work for 2 words that need to be capitalized in the same thread. It will leave the first one capitalized but then make the second one lowercase on all letters except for the first one. So if I need ABC and XYZ both left capitalized the thread will make ABC and Xyz.

EDIT #2: Alternatively is there a way that it just leaves any all capitalized word which is less than X number of characters alone?

EDIT #3: In regards to my EDIT #1, it seems that it wasn't working because there was a question mark at the end of the capitalized word. Any way to have a question mark or exclamation mark at the end of a ALL CAPS word not make the all caps word become lowercase?
