How to insert another plugin before the Jetpack sharing buttons

Jetpack sharing buttons are added immediately after the post content. In some cases, you may want to insert a new element between your post content and the sharing buttons.

To control whether that element will appear before or after the Jetpack sharing buttons, you will have to change the priority of the filter. In the example below, we’ve added an author box and used the priority 18. As long as the priority is less than 19, it will appear before the sharing buttons.

How to use your own resources in the sharing module

The sharing module includes an “advanced” option, allowing you to use your own Javascript and CSS files instead of the files added by Jetpack by default.

To get started, go to Settings > Sharing in your dashboard, and check the “Advanced” checkbox at the bottom of the page.

Then, you can add your own libraries by adding the following code in a functionality plugin or in your theme’s functions.php file:

function tweakjp_add_sharing_js() {
    wp_enqueue_script( 'sharing-js', WP_SHARING_PLUGIN_URL . 'sharing.js', array( ), 4 );
    $sharing_js_options = array(
	    'lang'   => get_base_recaptcha_lang_code(),
	    'counts' => apply_filters( 'jetpack_sharing_counts', true )
    );
    wp_localize_script( 'sharing-js', 'sharing_js_options', $sharing_js_options );
}
add_action( 'wp_enqueue_scripts', 'tweakjp_add_sharing_js' );

function tweakjp_add_sharing_css() {
    wp_enqueue_style( 'sharing', WP_SHARING_PLUGIN_URL. 'sharing.css', false, JETPACK__VERSION );
}
add_action( 'wp_enqueue_scripts', 'tweakjp_add_sharing_css' );

Once you’ve checked the option, you will be able to manually enqueue your own sharing js and css files.

You’ll note that Jetpack uses the WP_SHARING_PLUGIN_URL constant to build the path to load the libraries. You will have to change that constant by your own when re-enqueueing the sharing libraries.

You’ll also notice that you must localize the script and pass over lang and counts values to the sharing.js script.  A working example is included above.

Skip an Image with Photon

Once you activate the Photon module, it will automatically cache and serve all images you’ve added to your posts and pages that have been uploaded to your site.

You can exclude a specific image or an entire page from Photon easily.

To exclude an entire post or page from using Photon, you can modify this snippet to fit your needs and add it to your theme’s functions.php or a core functionality plugin:

function no_photon_by_page() {
  if ( is_page( 2 ) ) {
    add_filter( 'jetpack_photon_skip_image', '__return_true');
  }
}

add_action('wp', 'no_photon_by_page');

In this example, Photon won’t be used on the page with the ID of 2, but you can use any of the WordPress Conditional Functions.

If you’d like to exclude an image from being cached and served by Photon, you can add the following code to your theme’s functions.php file:

function my_photon_exception( $val, $src, $tag ) {
        if ( $src == 'YOUR_IMAGE_URL' ) {
                return true;
        }
        return $val;
}
add_filter( 'jetpack_photon_skip_image', 'my_photon_exception', 10, 3 );

If you’d like to disable Photon in other specific situations instead, you can check this tutorial.

How to remove Publicize options from the New Post screen

Publicize adds a set of options right above the “Publish” button in your dashboard. You can hide these options by adding the following code to a functionality plugin, or to your theme’s functions.php:

// Replace with admin_head-post.php for the edit post screen
add_action( 'admin_head-post-new.php', function() {
        global $publicize_ui;
        remove_action( 'post_submitbox_misc_actions', array( $publicize_ui, 'post_page_metabox' ) );
} );

Remove Jetpack’s Open Graph meta tags

If you’ve activated the Sharing or Publicize module, Jetpack will automatically add Open Graph meta tags to each one of your posts. These tags are used by Facebook to gather information about the post and build a post preview when one of your readers shares a post on Facebook.

If you already use another plugin to handle Open Graph meta tags on your site, we’ll automatically deactivate Jetpack’s Open Graph meta tags for you, to avoid any duplicates.

If, however, you’ve added these tags to your theme or built your own plugin, you’ll want to add the following code to your theme’s functions.php file or to your plugin, to deactivate Jetpack’s Open Graph meta tags:

add_filter( 'jetpack_enable_open_graph', '__return_false' );

How to remove the comment form from Carousel View

Sometimes, you may not want your readers to comment on single images. If that’s the case, you can deactivate comments on all attachment pages and in the Carousel view by adding this code snippet to your theme’s functions.php file:

function tweakjp_rm_comments_att( $open, $post_id ) {
    $post = get_post( $post_id );
    if( $post->post_type == 'attachment' ) {
        return false;
    }
    return $open;
}
add_filter( 'comments_open', 'tweakjp_rm_comments_att', 10 , 2 );

    define( 'RECAPTCHA_PUBLIC_KEY', 'XXXXXXX' );
    define( 'RECAPTCHA_PRIVATE_KEY', 'XXXXXXX' );
    
  3. Voila! Your email sharing buttons are now protected against spammers!

How to remove stylsheets added by Tiled Galleries and Carousel

If you wish to use your own stylesheets instead of the ones that are automatically added to the posts where you’ve inserted a Tiled Gallery, or a gallery using Carousel, you can add the following code to your theme’s functions.php file, or to a functionality plugin.

To remove Tiled Galleries’s stylesheet:

function tweakjp_rm_tiledcss(){
    wp_dequeue_style( 'tiled-gallery' );
}
add_action( 'wp_footer', 'tweakjp_rm_tiledcss' );

To remove Carousel’s stylesheet:

function changejp_dequeue_styles() {
    wp_dequeue_style( 'jetpack-carousel' );
}
add_action( 'post_gallery', 'changejp_dequeue_styles', 1001 );

How to change the credit link in the Infinite Scroll footer

If you’d like to change the default credit link appearing in the Infinite Scroll footer, you can use the infinite_scroll_credit filter, like so:

function tweakjp_cust_credit() {
	return '<a href="http://example.com">My Custom Link</a>';
}
add_filter( 'infinite_scroll_credit', 'tweakjp_cust_credit' );

Once you add that code to your theme’s functions.php, a new link will appear instead of the default “Powered by WordPress” link.
