<p>This plugin hooks into the media manager and generates a thumbnail everytime a<br />
PDF is uploaded. Generated thumbnail is an image of the first page in the<br />
uploaded document and is named <code>PDFNAME-thumbnail</code>, where <code>PDFNAME</code> is replaced<br />
by uploaded document filename.</p>
<p>Generated thumbnails are equivalent to <a href="https://codex.wordpress.org/Post_Thumbnails" rel="nofollow ugc">featured<br />
images</a> so that common thumbnail<br />
functions like <code>get_post_thumbnail_id()</code> can be used for PDF attachments. See<br />
<a href="https://codex.wordpress.org/Post_Thumbnails" rel="nofollow ugc">Post Thumbnails</a> for information<br />
on how you can use thumbnails efficiently.</p>
<p>Integration with the javascript media API is not yet implemented, therefore, you<br />
may need to reload the page before you can see generated thumbnail after an<br />
upload.</p>
<h4>Shortcodes</h4>
<p>It is possible to display a thumbnail linking to an uploaded PDF using the <code>[pdf_thumbnails_link]</code><br />
shortcode. The following attributes are supported:</p>
<ul>
<li><code>id</code> – Attachment ID (required)</li>
<li><code>size</code> – <a href="https://codex.wordpress.org/Post_Thumbnails#Thumbnail_Sizes" rel="nofollow ugc">Thumbnail size</a> (optional)</li>
<li><code>title</code> – <a href="https://developer.mozilla.org/en-US/docs/Web/HTML/Global_attributes#attr-title" rel="nofollow ugc">Anchor title attribute</a> (optional)</li>
<li><code>target</code> – <a href="https://developer.mozilla.org/en-US/docs/Web/HTML/Element/a#attr-target" rel="nofollow ugc">Anchor target attribute</a> (optional)</li>
<li><code>download</code> – <a href="https://developer.mozilla.org/en-US/docs/Web/HTML/Element/a#attr-download" rel="nofollow ugc">Anchor download attribute</a> (optional)</li>
</ul>
<p>Example 1: Display link to PDF with ID = 172 using <a href="https://codex.wordpress.org/Post_Thumbnails#Thumbnail_Sizes" rel="nofollow ugc">default thumbnail size</a></p>
<pre><code>[pdf_thumbnails_link id="172"]
</code></pre>
<p>Example 2: Display link to PDF with ID = 172 using thumbnail size (default 150×150)</p>
<pre><code>[pdf_thumbnails_link id="172" size="thumbnail"]
</code></pre>
<p>Thanks to <a href="https://wordpress.org/support/profile/mirgcire" rel="ugc">mirgcire</a> for providing the first<br />
version of the <code>[pdf_thumbnails_link]</code> shortcode.</p>
<h4>Developer API</h4>
<p>In most cases it should be sufficient to use built-in thumbnail functions from<br />
the WordPress API (<code>get_post_thumbnail</code> and similar). If you need to modify the<br />
way thumbnails are generated, you can override image generation with<br />
the <code>pdf_thumbnails_generate_image_blob</code> filter.</p>
<p>Example 1: Increase resolution for all generated PDF thumbnails</p>
<pre><code>// $blob is the current image blob (defaults to null, can be used for chaining)
// $filename is the PDF filename
add_action('pdf_thumbnails_generate_image_blob', function ($blob, $filename) {
    $imagick = new Imagick();
    $imagick->setResolution(200,200);
    $imagick->readImage($filename);
    $imagick->setIteratorIndex(0);
    $imagick->setImageFormat('jpg');
    return $imagick->getImageBlob();
}, 10, 2);
</code></pre>
<p>It is possible to modify generated thumbnail links using the <code>pdf_thumbnails_link_shortcode</code><br />
filter. The following attributes are available:</p>
<ul>
<li><code>$html</code> – Generated HTML code to be displayed</li>
<li><code>$attachmentId</code> – Sanitized ID of the PDF attachment</li>
<li><code>$size</code> – Sanitized thumbnail size</li>
<li><code>$atts</code> – <a href="https://codex.wordpress.org/Shortcode_API#Handling_Attributes" rel="nofollow ugc">Shortcode attributes (not sanitized)</a></li>
<li><code>$content</code> – Shortcode content (not sanitized)</li>
</ul>
<p>Example 2: Wrap thumbnail link in figure and append caption</p>
<pre><code>add_filter('pdf_thumbnails_link_shortcode', function ($html, $attachmentId, $size, $atts, $content) {
    return "<figure>$html <caption>Click to open image $attachmentId</caption></figure>";
}, 10, 5);
</code></pre>
<h3>TODO</h3>
<p>Add generated image to media browser after upload.</p>
<p>Outline of an implementation based on the javascript media API:</p>
<pre><code>// New uploads
wp.Uploader.queue.on('add', function (attachment) {

    if (attachment.subtype !== 'pdf') {
        return;
    }

    findThumbnailFor(attachment.ID).then(function (data) {

        // Add attachment thumbnail to browser
        var attachment = wp.media.model.Attachment.get(id)
        attachment.fetch().done(function () {
            wp.media.editor.open().state().get('library').add(generated attachment)
        });

    });
});
</code></pre>
<p>Filter: ajax_query_attachments_args</p>


PDF Thumbnails

The plugin does just what it says and the author is very helpful.  My only suggestion would be to add a short code that would insert a clickable thumbnail into a webpage.  Clicking on that would open the PDF in a viewer.
For example: [pdf-thumbnail id="1234" size="medium"]
... naturally this functionality would require host support for imagick.



Nice Job

Works just like it should. Can't believe this functionality isn't in the WP core. Thanks!

Excellent

This plugin generates a thumbnail everytime you upload a PDF attachment. Generated thumbnail is an image of the first page in uploaded document.
