Content Cards


Content Cards make ordinary web links great by making it possible to embed a beautiful Content Card to link to any web site.

By using OpenGraph data, Content Cards grabs the title, description and associated image to the links you embed — it’s similar to how you can embed other websites, such as YouTube, Twitter, SoundCloud and more.

For individual links, You can insert a Content Card via shortcode [contentcards url=""]. If you often use Content Cards for some website, you can register the domain name (for example: as an oEmbed provider via Plugin’s Settings page and then it will behave the same way other oEmbed providers do — you will just have to paste plaintext link to a separate paragraph an Content Card will be generated automatically.

This plugin was built by Arūnas Liuiza and Stanislav Khromov. It is being developed on GitHub. If you have any questions, issues, need support, or want to contribute, please let us know here.

There are two ways of inserting Content Cards into WordPress posts — shortcode and oEmbed.

Installation Instructions
  • Go to your admin area and select Plugins -> Add new from the menu.
  • Search for «Content Cards».
  • Click install.
  • Click activate.

Shortcode is the simplest way — You just put [contentcards url=""] into your post content and it gets replaced with a content card.
The shortcode accepts two attributes:

  • url (requried) — link to the site you want to display Content Card for.
  • target (optional) — if you want force links to open in new tab, use target="_blank" the same you would in actual links. This overrides the global option in Content Cards Settings page.

You can also insert the shortcode via a button in your visual editor. Start by pressing the Content Cards icon in WordPress visual editor’s (TinyMCE) toolbar. If no other plugins are adding their buttons, our button should be the last one in the top toolbar.


If You find that you are adding a lot of Content Cards from some single domain, You can save yourself some work, by white-listing that website as oEmbed provider in Content Card Settings page.

White-listed sites work the same way any other oEmbed provider in WordPress (YouTube, Twitter, SoundCloud, etc.) — You just need to put a plaintext link in a separate line in the WordPress editor and it will be replaced with a Content Card.

In Content Cards Settings page you can provide a list of white-listed sites. Put only domain name (, one domain per line.


Content Cards come with two default skins — Default and Default Dark — created by Stanislav Khromov. These skins are designed to provide minimal structural styling and blend in nicely with active theme by inheriting the font from the theme.

All skin template files can be found in content-cards/skins/* directory and they can be overwritten by providing the same template in active theme. For example, if you want to overwrite Content Cards stylesheet, You should add content-cards.css to Your theme directory.

Main skin template is content-cards.php. If no other skin templates are defined, Content Cards will fall back to this one, the same way WordPress falls back to index.php. If you want more granular templates, you can provide content-cards-{$type}.php templates, (content-cards-website.php, content-cards-article.php, etc.). $type is based on og:type meta data provided by website.

Content Cards provides five new template tags: get_cc_data(), the_cc_data() and the_cc_target():

  • get_cc_data( $key, $sanitize = false )returns $key OpenGraph data field (i.e. ‘title’, ‘description’, etc.). If valid $sanitize function is provided, the data is escaped using it.
  • the_cc_data( $key, $sanitize = false ) — according to WordPress tradition, it prints the same data that get_cc_data() would return.
  • the_cc_target() — a special helper function, that prints target="_blank" to links if needed (according to plugin/shortcode settings). Usage: <a href=""<?php the_cc_target() ?>>.
  • get_cc_image( $size, $sanitize = false )new in v0.9.1 — returns a link to image if there is one. Defaults to image, cached in Media Library, then to remote image. For cached images, you can use $size parameter to get specific WordPress image size.
  • the_cc_image( $size, $attrs = array() )new in v0.9.1 — prints an image tag. Uses get_cc_images().
  • the_cc_css_classes( $classes )new in v0.9.4 — a filterable template tag to print out CSS classes for the main div of Content Card. Custom CSS classes can also be passed via class attribute in the shortcode

Also since v0.9.1 you can use 'favicon' key in get_cc_data()/the_cc_data() to display favicon if the remote site provides one.

Adding CSS classes to the content card container

Filter Adding a class is easy thanks to the content_cards_css_classes filter.

add_filter('content_cards_css_classes', function($classes) {
    $classes[] = 'my_class';
    return $classes;

Համառոտագիր You can also add custom CSS classes on card-by-card basis using class attribute in the shortcode:

[contentcards url="" class="my_class"]

This plugin requires WP_Cron to be in proper working order.

Override the default options

If you are running this plugin on a multisite, you may wish to set site-wide settings and disable the Content Cards settings page on each separate blog.

To do this, you can use the content_cards_options hook, like this:

add_filter('content_cards_options', function($data) {

    //Disable admin page
    $data['enable_admin_page'] = false;

    return $data;

You can also override a number of other options using this hook. For example, here we set the theme to «default-dark»:

add_filter('content_cards_options', function($data) {

    //Disable admin page
    $data['skin'] = 'default-dark';

    return $data;

It seemed to still work as of May 2019. Had an initial rookie mistake of inserting hotlinked URLS into the shortlinks, but once that was resolved it seems to work for about a minute, then BAM added a third and the site borked, white page with error message "The site is experiencing technical difficulties. Please check your site admin email inbox for instructions." Had to deactivate plugin. 1 star. If it worked, 5 stars.

AFAICS, this works fine on Wordpress 5.2. I don't have any visible errors. It's a shame it hasn't been updated to include a Gutenberg block as manually typing in shortcodes over and over is a bit laborious (or in my case, duplicating the previously made shortcode block then changing the URL).

I love this! It is so easy to use and elegant result! Wiuth the shortcode it even works in a elementor carousel. I only wish one addition: being able to add an image when there is none (and not just a default placeholder) Thanks!

The plugin is technically great. But in Germany, where I live, you can get sued for violation of copyrights when you embed content this way, especially the pictures. I was just warned that a lawyer wants to sue unless I desist from showing the picture of an embedded article. So my suggestion to the programmer: include an option page where one can choose: -show headlines -show teasertext -show pictures
