Automatically close comments in the Carousel view

You can use the following code to automatically close comments in the Carousel view, based on the number of days you’ve defined in Settings > Discussion:

function jpcarousel_auto_close_comments( $open, $post_id ) {
	$post = get_post( $post_id );

	$days_old = (int) get_option( 'close_comments_days_old' );

	if ( ! $days_old )
		return $open;

	if( $post->post_type == 'attachment' && time() - strtotime( $post->post_date_gmt ) > ( $days_old * DAY_IN_SECONDS ) ) {
		return false;
	}
	return $open;
}
add_filter( 'comments_open', 'jpcarousel_auto_close_comments', 10 , 2 );

Remove Jetpack Sharing buttons in the Mobile Theme

You can add the following code to a functionality plugin to remove the Jetpack Sharing buttons in the Mobile Theme:

// Check if we are on mobile
function jetpackme_is_mobile() {

    // Are Jetpack Mobile functions available?
    if ( ! function_exists( 'jetpack_is_mobile' ) )
        return false;

    // Is Mobile theme showing?
    if ( isset( $_COOKIE['akm_mobile'] ) && $_COOKIE['akm_mobile'] == 'false' )
        return false;

    return jetpack_is_mobile();
}

// Let's remove the sharing buttons, but only if we're on a mobile device
function jetpackme_maybe_add_filter() {

    // On mobile, and on the home page?
    if ( jetpackme_is_mobile() ) {
        remove_filter( 'the_content', 'sharing_display', 19 );
		remove_filter( 'the_excerpt', 'sharing_display', 19 );
    }
}
add_action( 'wp_head', 'jetpackme_maybe_add_filter' );

// Build the function
function jptweak_remove_share() {
	remove_filter( 'the_content', 'sharing_display', 19 );
	remove_filter( 'the_excerpt', 'sharing_display', 19 );
}

How to disable specific shortcodes in Jetpack

Jetpack includes many shortcodes allowing you to embed videos, audio files, images, and other media into your posts.

If you want to deactivate a specific shortcode without deactivating the Shortcodes module, you can add the following code to your theme’s functions.php file, or to a functionality plugin:

function my_remove_shortcode_function( $shortcodes ) {
	$jetpack_shortcodes_dir = WP_CONTENT_DIR . '/plugins/jetpack/modules/shortcodes/';
	
	$shortcodes_to_unload = array( 'ted.php', 'soundcloud.php', );

	foreach ( $shortcodes_to_unload as $shortcode ) {
		if ( $key = array_search( $jetpack_shortcodes_dir . $shortcode, $shortcodes ) ) {
			unset( $shortcodes[$key] );
		}
	}
		
	return $shortcodes;
}
add_filter( 'jetpack_shortcodes_to_include', 'my_remove_shortcode_function' );

In the code above, you’ll need to add to or remove shortcodes from the $shortcodes_to_unload array. It requires the file name of the shortcode you want to deactivate.

Jetpack 2.3.4 is out! Included are a number of bug fixes and enhancements — from using the freshest Genericon assets to improving many of our translations, it’s the best Jetpack yet.

We’ve also lightened the load by dropping many of the “retina display” versions of WordPress Core assets that core has had come bundled with since 3.5. If you’re still running WordPress 3.4, it may be time to look at upgrading!

How to use Photon to serve custom cropped Post thumbnails

The Photon module resizes your site’s images on the fly, without cropping them. However, in some cases you might want Photon to apply a custom cropping when resizing certain images.

In the following example, we will use photon to serve Post thumbnails with custom cropping, and use a different cropping on single pages:

if( function_exists( 'jetpack_photon_url' ) ) {
    add_filter( 'jetpack_photon_url', 'jetpack_photon_url', 10, 3 );
}
function jeherve_display_custom( $content, $post ) {

	global $post;

	// If you didn't define a post thumnail, let's forget about all this
	if ( !has_post_thumbnail( $post->ID ) )
		return $content;

	// What's the cropping and the size of image we should use on Single pages?
	// See http://developer.wordpress.com/docs/photon/api/#crop for parameters
	if ( is_single() ) {
		$args = array(
		    'crop'   => '50,50,200px,200px',
		);
	}
	// resizing on other pages
	else {
		$args = array(
		    'resize'   => '200,400',
		);
	}

	// Let's create a Photon Image URL from the Post Thumbnail
	$feat_image_url = wp_get_attachment_image_src( get_post_thumbnail_id($post->ID), 'full');
	$photon_image_url = jetpack_photon_url( $feat_image_url[0], $args );

	// Let's build the image tag
	$our_image = sprintf( '<div class="post-media"><a class="featured-image" href="%1$s" title="%2$s"><img src="%3$s" class="wp-post-image" alt="Featured Image"></a></div>',
		esc_url( get_permalink() ),
		esc_attr( sprintf( __( 'Open %s', 'dot' ), get_the_title() ) ),
		esc_attr( $photon_image_url )
	);

	// Let's return the image, right before the post content
	return $our_image . $content;

}
add_filter( 'the_content', 'jeherve_display_custom' );

How to add a custom Open Graph image tag to your home page

When you share a post on Facebook, or when Jetpack Publicize publishes a post to your Facebook page, Facebook crawls the page and looks for Open Graph meta tags to build a complete post preview (with an image, title, description, …).

Jetpack automatically creates these meta tags for you, so you don’t have to worry about it!

However, Jetpack doesn’t create any image meta tag for your home page.
If you want to add your own custom image meta tag there, you can add this code to your theme’s functions.php file, or to a functionality plugin:

function fb_home_image( $tags ) {
	if ( is_home() || is_front_page() ) {
		// Remove the default blank image added by Jetpack
		unset( $tags['og:image'] );

		$fb_home_img = 'YOUR_IMAGE_URL';
		$tags['og:image'] = esc_url( $fb_home_img );
	}
	return $tags;
}
add_filter( 'jetpack_open_graph_tags', 'fb_home_image' );

It’s worth noting that the fallback image has to be larger than 200 x 200px, as per Facebook requirements. If your image is smaller, Facebook will ignore it.
