Shortcode output adding after new line

Question

I\'m trying to create a shortcode to add a CSS style attribute to a page. I added the following code to my theme\'s functions.php.

function add_style( $atts, $co         


        

Answer 1

The br tag gets inserted because of the default order in which WordPress processes your content – wpautop (the function which converts line breaks to p or br tags) is run before the shortcodes are processed.

The Solution:

Change the execution priority of wpautop so that it executes after the shotcodes are processed instead of before. Add this in your functions.php file:

remove_filter( 'the_content', 'wpautop' );
add_filter( 'the_content', 'wpautop' , 12);

Now there will be no extra p or br tags added inside your shortcode block. In fact there will not be any automatic conversion of line breaks to p and/or br tags at all. So if you want the legitimate line breaks to convert to p and br tags, you will need to run wpautop from inside your shortcode function, e.g.:

function bio_shortcode($atts, $content = null) {
   $content = wpautop(trim($content));
   return '
' . $content . '
';
}
add_shortcode('bio', 'bio_shortcode');
