January 14, 2016 Rampit Leave a comment

To display the Wordpres Shortcode return value in correct location, we need to use the “ob_start()” and “ob_get_clean()” as like below.

Source code

<?php
function your_shortcode_fun( $atts ){
ob_start();
?> <HTML> <here> ... <?php
return ob_get_clean();
}
add_shortcode( 'your_shortcode_name', 'your_shortcode_fun' );
?>

It will place the output in correct location.
