Display thumbnail of first attachment

  • I found this function in wp-includes/media.php:

    // as per wp_get_attachment_image_src, but returns an <img> tag
function wp_get_attachment_image($attachment_id, $size='thumbnail', $icon = false)

    I want to be able to display the thumbnail of the first post attachment in my loop, can I accomplish using this function?

    Is there a better way?

  • Justin Tadlock’s Get-the-Image-plugin. Works like a charm.

    First, get the image attachments of the post:

    global $post;
$attachments = get_children( array(
'post_parent' => $post->ID,
'post_type' => 'attachment',
'post_mime_type' => 'image',
'orderby' => 'menu_order ASC, ID',
'order' => 'DESC') );

    Next, go through them:

    foreach ( $attachments as $id => $attachment ) {
// do whatever you want here with the $id being the $attachment_id
}

    Like that.

    Hello, I’m trying to do exactly that but, which could be an example of the use of the $attachment_id ? Just for print the thumbnail i.e. ?

    I enjoy this plugin. It also has some great options in the settings.

    Upload/activate the plugin, then use <?php the_thumb(); ?> inside the loop to display the first image added to your posts/pages.

    If you are using the_content in this loop, and inserted your first uploaded image within the post. You can use preg_replace as shown below to strip the img tags from the_content. This way to can display your thumbnails as above however you want and have text only in the_content. Replace your the_content line with below to do so.

    <?php
    ob_start();
    the_content(‘Read the full post’,true);
    $postOutput = preg_replace(‘/<img[^>]+./’,”, ob_get_contents());
    ob_end_clean();
    echo $postOutput;
    ?>

    Using both examples, you can do some nifty stuff for example float left on the thumbnail, to text wrap the post title, etc as well as the content.
