Shortcode Empty Paragraph Fix

Description

Fix known issues when shortcodes are embedded in a block of content that is filtered by wpautop.

for Theme Developers

If you are developing a theme to provide this on a marketplace, you better embed the following code in your functions.php. This code filters only the shortcodes you defined. Otherwise you risk a failed review because the code in the plugin filters content in general which may is not acceptet.

function shortcode_empty_paragraph_fix( $content ) {

    // define your shortcodes to filter, '' filters all shortcodes
    $shortcodes = array( 'your_shortcode_1', 'your_shortcode_2' );

    foreach ( $shortcodes as $shortcode ) {

        $array = array (
            '<p>[' . $shortcode => '[' .$shortcode,
            '<p>[/' . $shortcode => '[/' .$shortcode,
            $shortcode . ']</p>' => $shortcode . ']',
            $shortcode . ']<br />' => $shortcode . ']'
        );

        $content = strtr( $content, $array );
    }

    return $content;
}

add_filter( 'the_content', 'shortcode_empty_paragraph_fix' );

Another solution that is acceptet at the envato (themeforest) marketplace comes from bitfade.
