Disable automatic formatting inside WordPress shortcodes

Question

I\'ve seen the tutorials on creating a (raw) shortcode that leaves the code inside it untouched,

Answer 1

In my case - this solution has broken one of the side shortcodes (revslider).

So I've found another solution here: http://wordpress-hackers.1065353.n5.nabble.com/shortcode-unautop-tp42085p42086.html

Which is to use another filter like this:

// Via http://www.wpexplorer.com/clean-up-wordpress-shortcode-formatting/
if ( !function_exists('wpex_fix_shortcodes') ) {
    function wpex_fix_shortcodes($content){
        $array = array (
            '<p>[' => '[',
            ']</p>' => ']',
            ']<br />' => ']'
        );
        $content = strtr($content, $array);
        return $content;
    }
    add_filter('the_content', 'wpex_fix_shortcodes');
}

It works fine for me :)

Answer 2

I solved this as best as possible by combining a slightly modified parse_shortcode_content function from Donal MacArthur (his originally manually calls wpautop... which I've removed. With the re-ordering of default filters to run wpautop much later... after the shortcode has already been processed instead of before.

// Clean up WordPress shortcode sormatting - important for nested shortcodes
// Adjusted from http://donalmacarthur.com/articles/cleaning-up-wordpress-shortcode-formatting/
function parse_shortcode_content( $content ) {

   /* Parse nested shortcodes and add formatting. */
    $content = trim( do_shortcode( shortcode_unautop( $content ) ) );

    /* Remove '' from the start of the string. */
    if ( substr( $content, 0, 4 ) == '' )
        $content = substr( $content, 4 );

    /* Remove '' from the end of the string. */
    if ( substr( $content, -3, 3 ) == '' )
        $content = substr( $content, 0, -3 );

    /* Remove any instances of ''. */
    $content = str_replace( array( '<p></p>' ), '', $content );
    $content = str_replace( array( '<p>  </p>' ), '', $content );

    return $content;
}

and moving the filters

// Move wpautop filter to AFTER shortcode is processed
remove_filter( 'the_content', 'wpautop' );
add_filter( 'the_content', 'wpautop', 99);
add_filter( 'the_content', 'shortcode_unautop', 100 );

EDIT:

The parse_shortcode_content() function is no longer required (if it ever was). Simply adjust the filter order.

Answer 3

After implementing @helgatheviking's solution on multiple websites, I'm convinced that only these lines are required:

// Move wpautop filter to AFTER shortcode is processed
remove_filter('the_content', 'wpautop');
add_filter('the_content', 'wpautop', 99);
add_filter('the_content', 'shortcode_unautop', 100);

Put them in your functions.php file and you're set.

Answer 4

Please see my answer here:

Remove wpautop from shortcode content / remove whitespace in buffering

It allows you to turn off wpautop for as many specific shortcodes as you want using this:

include "shortcode-wpautop-control.php";
chiedolabs_shortcode_wpautop_control(array('shortcodeone', 'shortcodetwo'));
