Highlighting parent page in WordPress menus

Menus in WordPress are a really simple and easy way to manage various navigation bars in a theme. wp_nav_menu() does a lot of the work automatically and includes a number of CSS classes for styling. Highlighting the current page is especially useful using .current-menu-item and .current-menu-ancestor classes. There was one issue I recently ran into though. […]

Gravatar Is More Than Just An Avatar

But did you know Gravatar can do more than just serve your avatar around the websites you frequent? Gravatar provides a personal profile that people can view to learn a little more […]

Tip: str_replace()

Here’s a quick little tip for using PHP’s str_replace() with many values. Sometimes it’s fine to just do this: $string = str_replace( ‘to_replace’, ‘replacement_string’, $string ); $string = str_replace( ‘to_replace’, ‘replacement_string’, $string ); $string = str_replace( ‘to_replace’, ‘replacement_string’, $string ); That method is fine but can get messy with many replacements. Another method is to […]

Directory Listing from a Path

$path = dirname( __FILE__ ); $listing = array_filter( scandir( $path ), function( $var ) { // remove special directories ‘.’ and ‘..’ from listing if ( preg_match( ‘/^[.]{1,2}$/’, $var ) ) { return FALSE; } // remove files from listing if ( !is_dir( $var ) ) { return FALSE; } return TRUE; } ); This […]

Modular Sidebar in WordPress

Like all good developers, I go back and look at past code to see what I could have improved and how I can apply the new knowledge to a current project.
