How can I get username into shortcode?

How can we get username into a shortcode

• How can we use $usernamein a shorcode <?php echo do_shortcode('[education="$username"]'); ?> But it doesn't work I have a shortcode as [education="username"]. It works manually [education="john-doe"] I want to get username into my shortcode on user profile page <?php echo do_shortcode("[education="username"]"); ?> But it's not working. What am I missing ?

• Answer:

  In php, single quoted strings don't support variable interpolation. Change from single quotes to double quotes. The double quotes inside your string will need to be escaped. Change: <?php echo do_shortcode('[education="$username"]'); ?> to <?php echo do_shortcode("[education=\"$username\"]"); ?>
