[SOLVED] Help using the_post_thumbnail

Hi all,

I am trying to set up a bit of code to show the latest post excerpt from a particular category. I want the post thumbnail to display if it is present in that post, and if not I want a default image to show. I am using this:

Code:

<?php global $post;

$myposts = get_posts('numberposts=1&category=8');

foreach($myposts as $post) :

?>

<a href="<?php the_permalink(); ?>">

<?php if (has_post_thumbnail()) the_post_thumbnail( array(100,100) ); else echo '<img class="social" src="default.jpg" alt="No Thumbnail" title="No Thumbnail" />';

?><br>

<?php the_title(); ?></a>

<?php endforeach; ?>

I can't get it to load the post thumbnail and I am wondering - am I wrong in assuming that the 'set featured image' box in the post is supposed to be the thumbnail? Or should I be choosing the thumbnail somewhere else? Or is my code just borked? :p

I'm not sure where you are placing that code but I would use the List Category Posts Plugin for what you are trying to do and the Feaured Image function works fine.

I am putting this in style and edit center column. I was hoping I could achieve it without using any more plugins as my site is starting to get a bit bloated with them.

So it sounds like featured image is what I need to choose the thumbnail, so there must be a problem with my code. I wonder if I actually need to specify which post has the thumbnail in my if statement? But that would make the whole thing pretty redundant.

Solved - I needed to add this: setup_postdata($post);

So the whole thing now reads

Code:

<?php global $post;

$myposts = get_posts('numberposts=1&category=13');

foreach($myposts as $post) :

setup_postdata($post);

?>

<a href="<?php the_permalink(); ?>">

<?php if ( has_post_thumbnail() ) the_post_thumbnail( array(100,100) ); else echo '<img border=0 class="social" src="defaultimage.jpg" alt="No Thumbnail" title="Example" />';

?><br>

<?php the_title(); ?></a>

<?php endforeach; ?>

And when added to 'style and edit center column' it shows the latest post title from category 13 and the thumbnail if there is one, or a default image if not. I set up multiple instances in a table to show posts from several of my categories on the home page.
