   Hello,

   When I added this code to my functions.php, it changed the length of the description. Now all the blog post content is showing in the RSS feed. Before it was cut off. Is there a way to limit the description to a max of 300 words?

   Thank you

     For what you are wanting you would want to change get_the_content to get_the_excerpt and that should allow it to display with the excerpt

   First of all let me thank you guys for various tutorials that have helped me over the time to fix several issues.

   I am just looking for a simple implementation.

   I just want my WordPress Category Feed e.g. wpbeginner.com/category/wp-tutorials/feed to have post featured image.

   So that under category/news/feed my articles show featured images in Google News Publishers sections.

     The method from our guide above should allow you to add images to your RSS feeds. The plugin has a paid plan if you wanted to specifically exclude other categories.

   This does not work. Unfortunately, when executed it displays the full post content and the full-size featured image instead of the excerpt.

     From your statement it does work. It adds the post thumbnail which is what this tutorial is about, you would want to change the get_the_content to get_the_excerpt to show the excerpt and not the full content.

   So how do you modify the function if you are using an ACF for your main custom thumbnail instead of the wordpress thumbnail?

   Hi all,

   I have 4 CPT in my site.
   Added all of them in my feed following: https://www.wpbeginner.com/wp-tutorials/how-to-add-custom-post-types-to-your-main-wordpress-rss-feed/

   But now I want to add the thumbnail as content into feed.
   Do you know how I can do it?

   That I need is similar to this post content but for all CPTs.

   Thanks and Regards,
   Dani

   So this just adds the image to the content. Not really desired for my needs. How can I add a new field so that I can use get_thumbnail when using the fetch_feed method in WordPress?

     You will need to connect to your website using an FTP client. Then locate the functions.php file (you will find it in /wp-content/themes/your-theme-folder/), edit the file using a plain text editor like Notepad. Undo the changes you made earlier. Finally, save the file and upload it back.

      RSS feed is an XML file. Usually when you are viewing an XML file in a browser it will only show you the code and will not execute the markup. You need to check your feed into a feed reader like Feedly.

    Is it possible to use this function with the WP RSS WIdget? I need to imports POSTs with thumbnails to another site.

    It was really a headache to see the RSS-to-email campaigns without no images because the RSS feed did not have the necessary tag to pull images from. Anyway, changed the functions.php file and now MailChimp can pull the required components and now the emails look beautiful.

    However, still the images in RSS feed look really big and wish to resize them to a suitable size. Needs to search more and find a solution for this.

    This accomplished getting the thumbnail included in the feed, but created two other problems:

    1) My feed now shows the full content instead of just the summary.

    2) The feed is also capturing my featured image from the content (the full image, not just the thumbnail) and this shortcode:

    [caption id="attachment_24496" align="aligncenter"width="739"]Caption Text[/caption]

    I assume there’s a way to correct both of these problems. Can anyone assist?

    Thank you so much for this code! Any suggestions for editing it so that the post thumbnail is a link to the post itself?

    I can't access wp-admin or the rss feed. I've tried making new wp-config.php files and nothing's working. Could someone help?

    Why we need check has_post_thumbnail()?

    get_the_post_thumbnail() return empty string if it couldn’t get thumbnail. Also, no need to define global $post. Filters calling from inside the loop.

    And why we call get_the_content(), is it nessesary?

    This code will enaugh:

    —
    function rss_post_thumbnail( $content ){
    $img = get_the_post_thumbnail( null, array(100, 80), array( ‘align’ => ‘left’, ‘style’ => ‘margin-right:15px;’ ) );
    $content = $img . $content;

    return $content;
    }
    add_filter( ‘the_excerpt_rss’, ‘rss_post_thumbnail’ );
    add_filter( ‘the_content_feed’, ‘rss_post_thumbnail’ );
    —

    Sorry for my english. It’s not my native.

    Trying this with the genesis magazine theme, no luck. The article is getting a wee bit dated. I was wondering if something might have changed in wordpress since this was originally written, or if maybe I’m just missing something. Been a while since I wondered down the rabbit hole chasing feed code

    /** Add thumbnail to Magazine theme feed*/
    function rss_post_thumbnail($content) {
    global $post;
    if(has_post_thumbnail($post->ID)) {
    $content = ” . ‘ID).'”>’. get_the_post_thumbnail($post->ID).’‘ .
    ” . /* full content option get_the_content() */get_the_excerpt();/*exercpt option */
    }
    return $content;
    }

    add_filter(‘the_excerpt_rss’, ‘rss_post_thumbnail’);
    add_filter(‘the_content_feed’, ‘rss_post_thumbnail’);

      Just tested the code from the article on a custom genesis child theme. It works fine. It won’t work with the default WordPress feed that firefox shows. But if you go to the atom feed, then it will work. If you are using a feedburner or another app, it should work.

    Ok…. wait a minute.

    Looks like this forces my RSS feed to be full content. Is that the case?

    More importantly, it looks like all this does is slap the tumbnail at the beginning of the content in the RSS feed. Am I missing something here?

    返信

    • Editorial Staff

      Yes, it does make the feed full content. You can change get_the_content() to get_the_excerpt().

      Yes, the point is to add the featured thumbnail in RSS. In most cases, that is added before the post. You can style the paragraph tag however you like. Add a float:left; or anything that you want.

    This works great, except that when there is a thumbnail present, the feed always repeats the post title within the content text (or excerpt text, as I’m using), which looks a little redundant. For posts without a thumbnail, the title is not repeated. Is there any way of removing this extra title text? It has no surrounding tags, so I can’t hide it using CSS.

    Is there anyway to align post thumbnails to the left of the entry in RSS feed?

    返信

    • Editorial Staff

      Yes, add styling to it. Change the Paragraph tag into a Div and tell it to float left with some margin.

    I think it’s better if you change code:

    $content=”.get_the_post_thumbnail($post->ID).”.$content;

    to maintain the original content.

      so what would the final code – all of it – look like?
      Non-coder who wants a thumbnail in her blog feed.

        The code in the article is the final code that you need… ofcourse if your theme doesn’t have thumbnail enabled, then you will need more.

    How would you make the post thumbnail link from RSS to the post?

    I don’t get along with PHP, any help is appreciated

    返信

    • Editorial Staff

      You would modify the function a little bit. Add this php code in the link tag: the_permalink($post->ID)
