bw_get_attached_image() – Get the attached image

You appear to be a bot. Output may be restricted

Description

Get the attached image

Return an array of images attached to a specific post ID Return Value: An array containing:

$image[0] => url 
$image[1] => width 
$image[2] => height 
$image[3] => attachment id 

Fix: In v2.4-beta.1218 we incorrectly tried using $args['ID'] instead og $args['post_parent']. A lot of the images displayed were incorrect. This has now been reverted to using $args['post_parent']

Usage

$array = bw_get_attached_image( $post_id, $number, $orderby, $image_size );

Parameters

$post_id

( integer ) optional – the parent post ID, or null

$number

( integer ) optional default: 1 – the number of posts to retrieve

$orderby

( string ) optional default: rand – how to select the image

$image_size

( string ) optional default: thumbnail –

Returns

array the selected image
