WordPress Help - What's Wrong With This "Latest Posts" Code?

I have following code in a sidebar of my WP theme:

<?php query_posts('category_id=all');?>
<?php $posts = get_posts('category=all&offset=0');
	foreach ($posts as $post) : start_wp(); ?>
<li><a href="<?php echo get_permalink() ?>"><?php the_title(); ?></a></li>
<?php endforeach; ?>

Code (markup):

It only displays 5 latest posts. How do I make it so it displays unlimited posts? Or how do I make it so I can control how many latest posts are displayed?

Somebody help, I'm a PHP newb

 

http://codex.wordpress.org/Template_Tags/get_posts

Need to pass in $numberposts to get_posts. The default is .... 5.

 

Try usiing <?php wp_get_archives('type=postbypost&limit=10'); ?> Instead of <?php $posts = get_posts('category=all&offset=0');

 

Thanks guys,

MegaMania:
tried that - it worked but also included the name of a blog hyperlinked to the homepage at the bottom of the list

shallowink:
great link, I may have fixed my problem with advice given there. This is what the code looks like and it seems to work:

<?php
 $lastposts = get_posts('numberposts=20');
 foreach($lastposts as $post) :
    setup_postdata($post);
 ?>
 <li><a href="<?php the_permalink(); ?>" id="post-<?php the_ID(); ?>"><?php the_title(); ?></a></li>
 <?php endforeach; ?>

Code (markup):

Thanks again guys, green rep on the way for both of you

 

I need help one more time (I'm totally worthless with PHP and didn't want to start a separate thread)

I'm trying to display random posts with hyperlinked title and excerpt of content. This is the code I could come up with but while hyperlinked titles are shown, no except is displayed. What am I doing wrong?

 <?php
 $rand_posts = get_posts('numberposts=5&orderby=rand');
 foreach( $rand_posts as $post ) :
 ?>
<li><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></li>
<div class="entry">
<?php the_excerpt() ?>
</div>
 <?php endforeach; ?>

Code (markup):

 

think get_posts isn't accessing all of the post data. from the same link I sent earlier...

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

setup_postdata is the addition , aint sure its the answer but good place to start...
