executing shortcodes through get_the_excerpt();

  • Hi, thanks for reading.

    I’m trying to execute a shortcode which exists in an excerpt on a site I’m working on.

    This works fine automatically using the_excerpt();

    But the_excerpt(); inserts an unnecessary <p>, which I do not want.

    So I’ve been using echo (get_the_excerpt();, which is fine except that it doesn’t execute the shortcode.

    I’ve played around with some filters and the do_shortcode($blah) stuff, all to zero effect.

    So if anybody could help me either:

    1. stop the_excerpt(); from inserting p tags, or
    2. make get_the_excerpt(); execute a shortcode

    I would be very much obliged.

    J

  • Any ideas at all?

    Is this in the wrong place on the forum? Should I repost in another section?

    This is the right forum but I think that do_shortcode() should work and nobody has a better answer.

    OK. Well, for the record, here are things I’ve tried. Please let me know if anything doesn’t look right so I can try again.

    Replacing the string replace function in the get_the_excerpt function (I commented out the bit of trim_excerpt which gets rid of script etc):

    function improved_trim_excerpt($text) {
            global $post;
            if ( '' == $text ) {
                    $text = get_the_content('');
                    /*$text = apply_filters('the_content', $text);
                     $text = str_replace('\]\]\>', ']]>', $text);
                     $text = preg_replace('@<script[^>]*?>.*?</script>@si', '', $text);
                     $text = strip_tags($text, '<p>'); */
                    $excerpt_length = 80;
                    $words = explode(' ', $text, $excerpt_length + 1);
                    if (count($words)> $excerpt_length) {
                            array_pop($words);
                            array_push($words, '[...]');
                            $text = implode(' ', $words);
                    }
            }
            return $text;
    }
    
    remove_filter('get_the_excerpt', 'wp_trim_excerpt');
    add_filter('get_the_excerpt', 'improved_trim_excerpt');

    I also tried this, which I saw suggested in a few places:

    add_filter( 'get_the_excerpt', 'shortcode_unautop');
    add_filter( 'get_the_excerpt', 'do_shortcode');

    And I tried this, with and without an echo:

    do_shortcode(get_the_excerpt());

    None of these are working for me. I will either dig out the reason, or create a workaround which fulfils my requirement, and post it back here.

    I think you should try the do_shortcode with an echo:

    echo do_shortcode(get_the_excerpt());

    I tried that- it just echoes the unexecuted shortcode, like this:

    [shortcode] the text of the excerpt

    Will keep digging when I have a chance…

    PS. Thanks! (:

    ‘echo do_shortcode()’ should work. What code did you use to add the shortcode function?

    Sorry I don’t follow- on my page template I tried:

    do_shortcode(get_the_excerpt());

    and

    echo do_shortcode(get_the_excerpt());

    But neither execute the shortcode. Without the echo nothing is output at all, with the echo I get the text of the shortcode included in the excerpt, as described above.

    The shortcode I’m using is created by a plugin: Star-Rating-for-Reviews. This shortcode is executed perfectly when I call the_excerpt();, but not when using do_shortcode(get_the_excerpt);

    Am I missing something?

    The shortcode is probably registered by the plugin when you call the_excerpt and so is not registered otherwise.

    You should find the ‘add_shortcode()’ function call in the plugin and add it to your code.

    Interesting… So I searched for the add_shortcode() call in the plugin, and it wasn’t there. So I had a look for the mechanism it was using. It seems that it was doing a preg_replace on the shortcode, and dumping the results back into the content via a couple of filters:

    add_filter('the_content', 'sr_addstar');
    add_filter('the_excerpt', 'sr_addstar');

    I realised all I needed to do was add another line:

    add_filter('get_the_excerpt', 'sr_addstar');

    And hey- it worked.

    So it was the plugin. Thanks vtxyzzy for pointing me in the right direction.

    Any idea how to transform that code for wp-filebase and NextGen gallery?

    Fringer? You would be better served starting your own topic and providing more detail in that new topic.

    Well, I thought it would be better to keep it all in one topic, since I’m trying to achieve the same thing as the original poster, only with different plugins.
