Disable Auto Format in wordpress

This is a great trick I found today while working on a problem for a client.

What was happening is that wordpress was wrapping her image in paragraph tags and causing it not to float right with text wrapping around it.

The solution was to add this to the functions.php file. (note, make sure you back up your funtions.php file first!)

function my_formatter($content) {
$new_content = '';
$pattern_full = '{(\[raw\].*?\[/raw\])}is';
$pattern_contents = '{\[raw\](.*?)\[/raw\]}is';
$pieces = preg_split($pattern_full, $content, -1, PREG_SPLIT_DELIM_CAPTURE);

foreach ($pieces as $piece) {
if (preg_match($pattern_contents, $piece, $matches)) {
$new_content .= $matches[1];
} else {
$new_content .= wptexturize(wpautop($piece));
}
}

return $new_content;
}

remove_filter('the_content', 'wpautop');
remove_filter('the_content', 'wptexturize');

add_filter('the_content', 'my_formatter', 99);

Now you simply add [raw] and [/raw] tags around the element you are having a problem with.
