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.
Retrieve XMP Data as an Array
$adobeXMP =& adobeXMPforWP::get_instance();

/** * Some default class properties can be modified. */ $adobeXMP->use_cache = true; // default $adobeXMP->max_size = 512000; // default $adobeXMP->chunk_size = 65536; // default /** * The $id can be a WordPress Media Library image ID, * or NextGEN Gallery image ID in the form of ngg-##. */ $image_xmp = $adobeXMP->get_xmp( $id ); echo '<p>Photograph by '.$image_xmp['Creator'].'</p>'; |
You can also hook the 'adobe_xmp_cache_dir' filter to modify the default cache directory.
Include a Shortcode in your 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"]
