I am searching for the right way of utilizing wordpress_get_attachment_image().
The next code:
<?php
$args = array(
'type' => 'attachment',
'category_name' => 'portfolio'
);
$attachments = get_posts($args);
print_r($attachments);
?>
Creates the next result:
Array
(
[0] => stdClass Object
(
[ID] => 54
[post_author] => 1
[post_date] => 2010-06-22 00:32:46
[post_date_gmt] => 2010-06-22 00:32:46
[post_content] => <a href="http://localhost/wordpress/wp-content/uploads/2010/06/Capture.jpg"><img class="alignnone size-medium wp-image-55" title="Capture" src="http://localhost/wordpress/wp-content/uploads/2010/06/Capture-300x114.jpg" alt="" width="300" height="114" /></a>
[post_title] => Our Own Site
[post_excerpt] =>
[post_status] => publish
[comment_status] => open
[ping_status] => open
[post_password] =>
[post_name] => our-own-site
[to_ping] =>
[pinged] =>
[post_modified] => 2010-06-22 00:40:22
[post_modified_gmt] => 2010-06-22 00:40:22
[post_content_filtered] =>
[post_parent] => 0
[guid] => http://localhost/wordpress/?p=54
[menu_order] => 0
[post_type] => post
[post_mime_type] =>
[comment_count] => 0
[filter] => raw
)
)
The next, however, does not return anything.
<?php
echo wp_get_attachment_image(54, array('300', '300'));
?>
What shall we be held doing wrong here?
Really, I do not think the recognized answer really solutions the question.
Your condition is the fact that you are passing within the publish id to wordpress_get_attachment_image(). As possible observed in the codex (http://codex.wordpress.org/Function_Reference/wordpress_get_attachment_image), you are designed to make use of the attachment id):
wp_get_attachment_image( $attachment_id, $size, $icon );
Quite simply, you need to make a move such as this:
$image_attr = wp_get_attachment_image_src(get_post_thumbnail_id($post->ID), 'medium');
The function wp_get_attachment_image only will get a picture which was submitted to wordpress, it does not output a picture within the content from the publish.
You need to output this content from the publish for the example image.
Like: echo $attachments['post_content'];
