<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>


Add EXIF and IPTC meta data to Attachment Post

Extends the attachment meta data to include a much wider range of EXIF and IPTC information when an image is uploaded. This plugin does not output any …

<p>If the appropriate checkboxes are selected in the Post submit box when saving the Post, the plugin reads the EXIF data of the Post’s <em>Featured Image</em> and adds Post Tags and a custom meta value “<em>location</em>” containing the serialized GPS location data of the image.</p>
<ul>
<li>If the Post has no Featured Image, or if the Featured Image’s EXIF data is incomplete, then nothing happens.</li>
<li>The EXIF data is read directly from the image file, not from a database entry.</li>
<li>If standard values “GPSLongitude” and “GPSLatitude” are not available in the Featured Image’s EXIF data, the post will not be updated with the custom meta field. (A pre-existing value will not be deleted, if this happens.)</li>
<li>When saving Post Tags, the standard taxonomy <code>post_tag</code> is set. If you need to modify this, for example in the case of a custom taxonomy, then you can use the filter hook <code>update-post-with-exif-data/post_taxonomy</code> to change it.</li>
<li>If you want to see the custom meta value containing serialized GPS location data in the WordPress backend, you’ll need to parse the data and add this field yourself. A good solution for this is the “Advanced Custom Fields” plugin by Elliot Condon, with field type “Google Map”.</li>
<li>Developers: see the code for a WordPress action hook <code>update-post-with-exif-data/no-gps</code>, which fires in the event that there is no valid GPS data available in the Featured Image.</li>
</ul>
