Using keyboard shortcuts to save your time

In the WordPress visual editor you can use a combination of keys to do things that normally need a mouse, trackpad or other input device. Rather than reaching for your mouse to click on the toolbar, you can use the following keyboard shortcuts.


I like to use the formatting shortcuts. It’s easy way to create the headings, lists, quotes, etc.

How to remove empty values from an array

We frequently need to remove empty values from an array in PHP. I think doing it by function array_filter is a good idea.


$a = array( 1, 5, 0, 'c', '', 'php', ' ', 'html', 189 );

$b = array_filter( $a, 'my_empty' );
function my_empty( $var ) {
 $var = trim( $var );
 if ( '' == $var ) {
 return false;
 return true;

print_r( $b );

It can remove all empty string and extra white space values, but keeps the zero number.

Make buttons have pressed effect

Here I will introduce the small trick. You only add a little code, then make buttons have pressed effect. Just like a button is really pressed. See the codes below.

See the Pen Pressed Button by wpaesthetic (@wpaesthetic) on CodePen.

Just doing two things:

  1. Set the position property of the button tag with relative value.
  2. Set the top property with 1px value.
