+ === Plugin Name ===
2
+ Contributors: chrisscott
3
+ Tags: thumbnails, image
4
+ Requires at least: 2.9.2
5
+ Tested up to: 3.2.1
6
+ Stable tag: 0.8
7
+
8
+ Adds multiple post thumbnails to a post type. If you've ever wanted more than one Featured Image on a post, this plugin is for you.
9
+
10
+ == Installation ==
11
+
12
+ 1. Upload the `multi-post-thumbnails` directory to the `/wp-content/plugins/` directory
13
+ 2. Activate the plugin through the 'Plugins' menu in WordPress
14
+ 3. Register a new thumbnail for the post type you want it active for. If `post_type` is not set it defaults to `post`.
15
+
16
+ if (class_exists('MultiPostThumbnails')) {
17
+ new MultiPostThumbnails(array(
18
+ 'label' => 'Secondary Image',
19
+ 'id' => 'secondary-image',
20
+ 'post_type' => 'post'
21
+ )
22
+ );
23
+ }
24
+ 4. Display the thumbnail in your theme:
25
+
26
+ <?php if (class_exists('MultiPostThumbnails')
27
+ && MultiPostThumbnails::has_post_thumbnail('post', 'secondary-image')) :
28
+ MultiPostThumbnails::the_post_thumbnail('post', 'secondary-image'); endif; ?>
29
+
30
+ == Frequently Asked Questions ==
31
+
32
+ = I'm trying to upgrade to a new verions of WordPress and get an error about `MultiPostThumbnails` =
33
+
34
+ This is caused by using the example in previous readmes that didn't do a check for the `MultiPostThumbnails` class existing first. This has been corrected in the Installation section.
35
+
36
+ = How do I register the same thumbnail for multiple post types? =
37
+
38
+ You can loop through an array of the post types:
39
+
40
+ if (class_exists('MultiPostThumbnails')) {
41
+ $types = array('post', 'page', 'my_post_type');
42
+ foreach($types as $type) {
43
+ $thumb = new MultiPostThumbnails(array(
44
+ 'label' => 'Secondary Image',
45
+ 'id' => 'secondary-image',
46
+ 'post_type' => $type
47
+ )
48
+ );
49
+ }
50
+ }
51
+
52
+ = How do I use a custom thumbnail size in my theme? =
53
+
54
+ After you have registered a new post thumbnail, register a new image size for it. e.g if your post thumbnail `id` is `secondary-image` and it is for a `post`, it probably makes sense to use something like:
55
+
56
+ `add_image_size('post-secondary-image-thumbnail', 250, 150);`
57
+
58
+ This will register a new image size of 250x150 px. Then, when you display the thumbnail in your theme, update the call to `MultiPostThumbnails::the_post_thumbnail()` to pass in the image size:
59
+
60
+ `MultiPostThumbnails::the_post_thumbnail('post', 'secondary-image', NULL, 'post-secondary-image-thumbnail');`
61
+
62
+ You can register multiple image sizes for a given thumbnail if desired.
63
+
64
+ == Screenshots ==
65
+
66
+ 1. Admin meta box showing a new thumbnail named 'Secondary Image'.
67
+ 2. Media screen showing the link to use the image as the 'Secondary Image'.
68
+ 3. Admin meta box with the 'Secondary Image' selected.
69
+
