Retrieve the following Adobe XMP / IPTC information from images in the WordPress Media Library and NextGEN Galleries:
- Creator Email
- Owner Name
- Creation Date
- Modification Date
- Label
- Credit
- Source
- Headline
- City
- State
- Country
- Country Code
- Location
- Title
- Description
- Creator
- Rights
- Keywords
- Hierarchical Keywords
The extracted XMP / IPTC data is cached on disk to improve performance and is refreshed if / when the original image is modified.
You can use the plugin in one of two ways; calling a method in your theme template(s) or using the [xmp] shortcode in your content.
There are no plugin settings - simply install and activate the plugin.
How do I retrieve XMP data as an array?
$adobeXMP =& adobeXMPforWP::get_instance();
$xmp = $adobeXMP->get_xmp( $image_id );
echo '<p>Photograph by ' . $xmp[ 'Creator' ] . '</p>';
How do I include a shortcode in a post or page?
[xmp id="101,ngg-201"]
This shortcode prints all the XMP information for Media Library image ID "101" and NextGEN Gallery image ID "201". The XMP information is printed as a definition list <dl> with a class name of "xmp_shortcode" that you can style for your needs. Each <dt> and <dd> element also has a style corresponding to it's title - for example, the "Creator" list element has an "xmp_creator" class name. Here's an example of the definition list HTML:
<dl class="xmp_shortcode">
<dt class="xmp_credit">Credit</dt>
<dd class="xmp_credit">JS Morisset</dd>
<dt class="xmp_source">Source</dt>
<dd class="xmp_source">Underwater Focus</dd>
<dt class="xmp_hierarchical_keywords">Hierarchical Keywords</dt>
<dd class="xmp_hierarchical_keywords">What > Photography > Field of View > Wide-Angle > Fish-Eye</dd>
</dl>
The shortcode can also take a few additional arguments:
include (defaults to "all")
Define which XMP elements to include, for example:
[xmp id="101" include="creator,creator email"]
exclude (defaults to none)
Exclude some XMP elements, for example to print all XMP elements, except for the "creator email":
[xmp id="101" exclude="creator email"]
show_title (defaults to "yes")
Include / exclude the <dt> definition titles.
[xmp id="101" show_title="no"]
show_empty (defaults to "no")
Include / exclude empty <dd> definition values.
not_keyword (defaults to none)
Exclude a list of (case incensitive) keywords, for example:
[xmp id="101" not_keyword="who,what,where"]
To exclude a hierarchical keyword list, use hyphens between the keywords, for example:
[xmp id="101" not_keyword="who,what,where,who-people-unknown"]
