<p>WordPress extracts image meta data from a file when it is uploaded and adds it to the newly created Attachment Post in the database. This Plugin extracts and saves a much wider range of EXIF and IPTC information than WordPress Core usually stores.</p>
<p>This Plugin currently supports JPEG and WEBP files.</p>
<p>This plugin does not output any data on the website or in the WordPress Admin area. If this is required, a developer will need to amend the Theme or Plugin which generates the HTML for the website.</p>
<p>The Plugin does not add any information to Attachment Posts which have already been created. (The Plugin does, however, update the stored meta data when a new image is uploaded to an existing Attachment Post; for example when the <a href="https://wordpress.org/plugins/enable-media-replace/" rel="ugc">Enable Media Replace Plugin</a> is used.)</p>
<p>The information is not visible in the Media editor, but is available to developers when using the <code>wp_get_attachment_metadata</code> function. The data is stored in a subset of the array returned by this function, within the array key <code>shp_additional_metadata</code>.</p>
<p>e.g.</p>
<pre><code><?php
$attachment_metadata = wp_get_attachment_metadata($attachment_id);
var_dump($attachment_metadata['shp_additional_metadata']);
</code></pre>
<h3>Hooks</h3>
<p>The data array can be manipulated using <code>add_filter</code> once it has been retrieved from the file, using the following hooks.</p>
<h4>All additional data</h4>
<p>All IPTC data which is added by the plugin.</p>
<pre><code><?php
apply_filters('shp_additional_metadata/iptc', $exif['iptc'], $source_path);
</code></pre>
<h4>IPTC data</h4>
<p>All data which is added by the plugin.</p>
<pre><code><?php
apply_filters('shp_additional_metadata/all_exif', $exif, $source_path);
</code></pre>
