FAQ

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"]
