excerpt_more filter does not follow $post even after setup_postdata($post)

[jimmynguyc]

A simple test by returning the $post-ID in the filter function and this is what I get :

// Default single post with ID 22

if (have_posts()) : while (have_posts()) : the_post();
    the_content(); 
endwhile; endif;


// Additional custom query
add_filter('excerpt_more',create_function('',"return $post->ID;"));

$myposts = get_posts($args);

foreach ($myposts as $post) : setup_postdata($post);
    echo $post->ID; // gives 519
    the_excerpt();  // shows 22 instead of 519
endforeach;

This is because setup-postdata() doesn't set the global $post variable. this is done in WP_Query().the_post();

add the "global $post;" call directly before your foreach loop:
this should work :)

Default single post with ID 22

if (have_posts()) : while (have_posts()) : the_post();

the_content();

endwhile; endif;

Additional custom query
add_filter('excerpt_more',create_function(,"return $post->ID;"));

$myposts = get_posts($args);

global $post;

foreach ($myposts as $post) : setup_postdata($post);

echo $post->ID; gives 519
the_excerpt(); shows 22 instead of 519

endforeach;
