JSM's Adobe XMP / IPTC for WordPressbyJS Morisset

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
• 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.

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 '
Photograph by '.$image_xmp['Creator'].'
';

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

with a class name of xmp_shortcode that you can style for your needs. Each

and

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:

Hierarchical Keywords

    Field of View > Wide-Angle > Fish-Eye

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

definition titles.

[xmp id="101" show_title="no"]

• show_empty (defaults to “no”)

Include / exclude empty

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"]
