I am using a plugin to forward photo posts from wordpress to a tumblr blog.

I have the following code:

//post blog to tumblr
function postBlogTumblr($postID)
{
    $URLServer = "http://www.tumblr.com/api/write";
    $t_post = get_post($postID);
    $t_url = get_permalink($postID);
    $tumblr_data = unserialize(get_option("tumblr"));
    $postdata['email'] = $tumblr_data['tumblr_login_email'];
    $postdata['password'] = $tumblr_data['tumblr_login_pass'];
    $postdata['type'] = "photo";

    $postdata['source'] = the_attachment_link($attachment_id);

    $postdata['caption'] = $t_post->post_title."(via adamblanchard.co.uk)";   
    $postdata['state'] = "published";
    $postdata = http_build_query($postdata);   
    $result = datapost($URLServer,$postdata);

}

I believe I am using the right method on the $postdata['source'] line, but I am unsure how to go about getting the attachment id.

Any guidance would be greatly appreciated.

you can use this snippet to get the first image of a post attachment id:

$images =& get_children( 'post_type=attachment&post_mime_type=image&post_parent=' . $postID );
$attachment_id = $images[0]->ID;

this small code give you the first image from the post, if is inside the gallery of the post and is! the first image in the gallery of the post.

$attachments = get_children( array(
                'post_parent'    => get_the_ID(),
                'post_type'      => 'attachment',
                'numberposts'    => 1, // show all -1
                'post_status'    => 'inherit',
                'post_mime_type' => 'image',
                'order'          => 'ASC',
                'orderby'        => 'menu_order ASC'
                ) );
foreach ( $attachments as $attachment_id => $attachment ) {
    echo wp_get_attachment_image( $attachment_id );
}

If the image in question is attached to the post, then you can get the URL of the image using the wp_get_attachment_url function. (Read more in the codex here)

  • That function requires the attachment id also, which is the thing I am struggling to find. Jun 13 '11 at 13:17
