I'm working on my own custom theme (first custom WP work so I'm a real beginner) and need help in listing the first 20 words of a list of recent posts.

I managed to solve this with manual? excerpt but I would like to just get the first 20 words of the content, but not sure how to best do that. The application is in a list on my start page.

My current code looks like this

    <?php
    $cdRP = get_theme_mod('cd_recent_posts', '3');
    $args = array( 'numberposts' => $cdRP );
    $recent_posts = wp_get_recent_posts( $args );
    foreach( $recent_posts as $recent ){
        echo '<div class="grid-cell"><a class="fpItems" href="' . get_permalink($recent["ID"]) . '">';
        if ( has_post_thumbnail( $recent["ID"]) ) {
            echo  '<div>' . get_the_post_thumbnail($recent["ID"],'thumbnail') . '</div>';
        }
        echo '<div>'
        . '<h3>' . $recent["post_title"] . '</h3>'

        . '</div></a></div>';
    }
    wp_reset_query();
?>

All of this happens outside the loop. I tried to find the answer in the forums, but failed, so sorry if this has been asked and answered before. Trying my best to learn to code this wonderful tool my self :)

Use wp_trim_words()

wp_trim_words( get_the_content(), 20 )

As you're outside the main loop

wp_trim_words( $recent[ 'post_content' ], 20 )

If you want to apply the same filters as to the_content() in the main loop

wp_trim_words( apply_filters( 'the_content', $recent[ 'post_content' ] ), 20 )

  • Since you're outside The Loop, you might need to use wp_trim_words( get_the_content( $recent["ID"] ), 20 );.

    @PatJ get_the_content doesn't take the ID, but he has the post_content already available Jan 5, 2018 at 16:23

    Life savers. Thank you guys :) I managed to guess by just typing logical stuff that $recent["post_content"] got the content, but didn't manage to trim it. Hoped that $recent[post_excerpt"] worked, but no such luck ;) Thank your your help. both of you @PatJ and Nicolai

    @PatJ I already had written your exact suggestion, before I remembered the restriction. Jan 5, 2018 at 16:37

Working Solution turned out to be simple :)

    <?php
    $cdRP = get_theme_mod('cd_recent_posts', '3');
    $args = array( 'numberposts' => $cdRP );
    $recent_posts = wp_get_recent_posts( $args );
    foreach( $recent_posts as $recent ){
        echo '<div class="grid-cell"><a class="fpItems" href="' . get_permalink($recent["ID"]) . '">';
        if ( has_post_thumbnail( $recent["ID"]) ) {
            echo  '<div>' . get_the_post_thumbnail($recent["ID"],'thumbnail') . '</div>';
        }
        echo '<div>'
        . '<h3>' . $recent["post_title"] . '</h3>'

        . wp_trim_words( $recent["post_content"], 20 )

        . '</div></a></div>';
    }
    wp_reset_query();
?>

You can achieve this by using the following;

$content = get_the_content();
echo substr($content, 0, 20);

or

$content = get_the_excerpt();
echo substr($content, 0, 20);

This will limit the character count to 20.

    That'll trim to 20 characters, not words, though.
