I am while using Loop during my own web page to obtain the last three posts from Wordpress.

        $args = array( 'numberposts' => 3 );
        $myposts = get_posts( $args );
        foreach( $myposts as $post ) :  setup_postdata($post); ?>

                    <!-- DATE -->
                    <div class="date">
                    <?php the_time('m F Y');?>

                    <!-- TITLE -->
                    <div class="title">
                    <?php the_title(); ?>

                    <!-- SNIPPET -->
                    <div class="content">
                    <?php the_excerpt(); ?>
<?php endforeach; ?>

Things are working fine - except the_excerpt(). I want about 15-20 words of plain text in the publish to exhibit like a preview. How do you start carrying this out?

Thanks :)

You could attempt using something similar to this to seize the very first 20 words from the publish if there's no excerpt available.

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

To personalize how big the excerpt give a customer excerpt filter, see here

The sub str without a doubt works...it use img also...like if u possess a image and also you would like your text to become limited the sub_str works!
