How to Disable Automatic formatting in WordPress posts
WordPress has a habit of automatically formatting codes which can become a huge problem for some bloggers. You can use the Syntax Highlighter Plugin or encode all codes manually, but these ways have their own shortcomings. Recently working on a client’s site, we discovered a useful trick that will disable automatic formatting in WordPress posts through the use of shortcodes.
First you would need to open your theme’s functions.php file and paste the following code:
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);
Once you have pasted the codes above and uploaded the file, then you are ready to use the shortcodes. Simply use the shortcode below when writing the post:
[raw]Unformatted code[/raw]
