Simple Blog Card


Blog card

  • Generated with shortcode
  • Generated with block
  • Can specify the number of characters displayed in the description.
  • Displays an ogp image.
  • Can specify the size of the displayed ogp image.
  • Can change the title and description.


A redirect loop occurs when all three of the following factors are met:
* When two sites with different domains embed “Simple Blog Card” for each other on their top pages.
* When two sites with different domains are on the same server (same IP address).
* When the ”Simple Blog Card” caches of two sites on different domains are empty.

How it works


  • Template files allow for flexible customization.
  • The default template file is template/simpleblogcard-template.php. Using this as a reference, you can specify a separate template file using the filters below.
/** ==================================================
 * Filter for template file.
    function () {
        $wp_uploads = wp_upload_dir();
        $upload_dir = wp_normalize_path( $wp_uploads['basedir'] );
        $upload_dir = untrailingslashit( $upload_dir );
        return $upload_dir . '/tmp/simpleblogcard-template.php';
  • CSS files can be set separately. Please see the filters below.
/** ==================================================
 * Filter for CSS file.
    function () {
        $wp_uploads = wp_upload_dir();
        $upload_url = $wp_uploads['baseurl'];
        if ( is_ssl() ) {
            $upload_url = str_replace( 'http:', 'https:', $upload_url );
        $upload_url = untrailingslashit( $upload_url );
        return $upload_url . '/tmp/simpleblogcard.css';

It is simple and has enough functionality for my needs.If you use this, you can treat the link cards as blocks and set preferences of each card from the block editor.Many link card plug-ins cannot handle non-utf8 encoded pages correctly, but you can set proper encodings manually if you use this.I’ve been using Pz-LinkCard and it is also good, but I prefer this one.
