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; ?>

- == 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
-
70
