How to make custom RSS feed using the post title?

    Hi,

    I want to display RSS content on each post based on the title of each post.

    For example,
    [wp_rss_retriever url=”https://news.google.com/search?q=%5Bpost_title%5DE&hl=en-US&gl=US&ceid=US%3Aen” items=”10″ excerpt=”50″ read_more=”true” credits=”true” new_window=”true” thumbnail=”200″ cache=”7200″]

    I created a function for shortcode [post_title] in the theme functions.php file.

    function post_title_shortcode(){
    return get_the_title();
}
add_shortcode('post_title','post_title_shortcode');

    But it’s not working. I need the [post_title] value to be processed before the RSS url is checked. Right now it’s not.

    Any ideas how to make this concept work here?

    Thanks for your help!!

    Hello,

    Using shortcodes inside attributes is not currently possible according to the Shortcodes API. However, you could follow the advice here to accept dynamic parameters as attributes: https://wordpress.stackexchange.com/questions/133472/allowing-shortcodes-inside-attributes

    Note: you would want to create your own shortcode that calls the wp-rss-retriever shortcode inside of it instead of editing the plugin itself.

    This does what you’re trying to do:

    
// [custom_rss]
add_shortcode( 'custom_rss', 'execute_custom_rss_shortcode' );
function execute_custom_rss_shortcode() {
  return do_shortcode('[wp_rss_retriever url="https://news.google.com/rss/search?q=' . get_the_title() . '&hl=en-US&gl=US&ceid=US%3Aen" items="10" excerpt="50" read_more="true" credits="true" new_window="true" thumbnail="200" cache="7200"]');
}

    Awesome, thanks!

    What’s the recommended way to change the CSS styles for the titles, excerpts, etc?

    You can target the elements via CSS selectors .wp_rss_retriever_title, .wp_rss_retriever_container, .wp_rss_retriever_image. You may need to include the !important flag depending on how you use CSS specificity
