Wordpress: get posts and show 50 first characters

votes

I want to show the three latest posts with the 50 first characters. And a "read more" link at the end. Like this:

My first post

Lorem ipsum dolor sit amet, consectetur adipiscing elit. Aenean vulputate. Read more...

My second post

Lorem ipsum dolor sit amet, consectetur adipiscing elit. Aenean vulputate. Read more...

My third post

Lorem ipsum dolor sit amet, consectetur adipiscing elit. Aenean vulputate. Read more...

Do I use get_posts? How do I do it?

This became my solution:

In the template:

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

<h2 class="news"><?php the_title(); ?></h2>
<?php the_excerpt(); ?>

<?php endforeach; ?>

In functions.php:

function new_excerpt_more($more) {
       global $post;
    return '... <a href="'. get_permalink($post->ID) . '">Read more</a>';
}
add_filter('excerpt_more', 'new_excerpt_more');


function custom_excerpt_length( $length ) {
    return 20;
}
add_filter( 'excerpt_length', 'custom_excerpt_length', 999 );

You can use this without the going to functions.php page. 

<?php
$args = array( 'numberposts' => 1 );
$lastposts = get_posts( $args );
foreach($lastposts as $post) : setup_postdata($post); ?>
<h2><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></h2>
<?php the_content_rss('', TRUE, '', 33); ?> <a class="continue" href="<?php     the_permalink() ?>">Continue Reading &raquo;</a>
<?php endforeach; ?>

Yes you use get_posts:

$options = array(
    'number_of_posts' => 3
);

$myposts = get_posts($options);
foreach( $myposts as $post ) {
    setup_postdata($post);
    echo '<h2>' . the_title . '</h2>';
    echo the_content();
}

You could use something like "$mycontent = get_the_content()" and then manipulate it with phps substring, but honestly: DO NOT DO IT!

For your read more function Wordpress has the perfectly fine more tag in the editor, which will automagically work for you, if you try something like this:

foreach( $myposts as $post ) {
    setup_postdata($post);
    echo '<h2>' . the_title . '</h2>';
    echo the_excerpt();
    echo '<a href="' . the_permalink() . '">More &raquo;</a>';
}
