wordpress coders: question

[fris]

Anyone know why one of them is working and one isnt?

im just counting the number of images in a post

<?

// doesnt work

function postcount() {
global $post;
$content = $post->post_content;
preg_match_all('/<img/', $content, $images);
echo count($images[0]);
}

// works
function postcount() {
global $wpdb, $id;
$post = $wpdb->get_var("SELECT post_content FROM $wpdb->posts WHERE ID = $id");
$post_content = apply_filters('the_content', $post);
preg_match_all('/<img/', $post_content, $images);
echo count($images[0]);
}

?>

hi...
Because in the second you extract something from the data base... and display the results by applying the filters to format the results...

The first one is not working first, because you don't have content (you don't take out anything from the data base)... this is the reason

cause global $post saves $post->ID; $post->post_content; etc and everything from the current post, figured it would do the same

Doesn't $post->post_content give the content without formatting, just like get_the_content()?

If so, you might want to check this out: http://www.web-templates.nu/2008/08/...th-formatting/
