Shortcodes enable developers to create special kinds of content, following the idea of macros. One very famous short code is “gallery” needed to insert a gallery of images into a post.
The good thing about shortcode’s is that final users are free to decide where to insert them.
WordPress’s Shortcode API handles all the tricky parsing, making developers life much easier. The following is a snippet for a Shortcode – in order to make it work you have to add it to your functions.
Here is a snippet to add 64×64 images to the Admin Post Columns in WordPress. Having thumbnails may result extremely helpful, specially if you have hundreds of posts.
You have to copy and paste the following code into the functions.php file of your theme.
function posts_columns($defaults){ $defaults['the_post_thumbs'] = __('Thumbs'); return $defaults; } function posts_custom_columns($column_name, $id){ if($column_name === 'the_post_thumbs'){ echo the_post_thumbnail( array(64, 64) ); } } add_filter('manage_posts_columns', 'posts_columns'); add_action('manage_posts_custom_column', 'posts_custom_columns', 10, 2); Instead of array(64, 64) you can also use default image sizes like ‘featured_thumbnail’, ‘thumbnail’, ‘medium’, ‘large’ and ‘full’.
There is a simple way to know this. The following code takes white (#ffffff) divided it by two as our reference color. If the comparing color is lower than the reference color, then the given color is dark, otherwise it’s light color.
function isLightOrDark($hexcolor) { return (hexdec($hexcolor) > 0xffffff/2) ? 'light color' : 'dark color'; }
