<p>A plugin which adds a shortcode: <code>[gallery_from_regex_matches]</code> in which a regex attribute should be specified. It will then look for matches in the descriptions and titles of all published images in your library, and create a gallery from the matches it finds.</p>
<ul>
<li>Use for example like this <code>[gallery_from_regex_matches regex="lillill" exclude_ids="764"]</code>, and it will generate a gallery of all your pictures of “Lillill”, except the one which has ID 764.</li>
<li>Sometimes it might be advicable to limit the amount of matches. that can be achieved by adding <code>limit</code> to the shortcode. <code>[gallery_from_regex_matches regex="lillill" exclude_ids="764" limit="10"]</code>.</li>
<li>Sometimes you want to make a gallery of “cats” but not “catsup”, but you don’t want to add <a href="https://dev.mysql.com/doc/refman/5.7/en/regexp.html" rel="nofollow ugc">word boundary</a> <code>[[:>:]]</code>, in this case you can <code>exclude_regex=catsup</code>. Then it could look something along the line of <code>[gallery_from_regex_matches regex="cats" exclude_regex="catsup"]</code>.</li>
<li>The same params (except for <code>ids</code>) as for the <code>[media]</code> shortcode can be used (as this plugin calls that shortcodes callback function (<code>gallery_shortcode()</code>) to generate the gallery), so if you want to specify a particular type (style) of gallery from for example your cat pictures , this might do the trick: <code>[gallery_from_regex_matches regex="(cat|kitten)" type="square"]</code>.</li>
<li>The regular expressions follows the <a href="https://dev.mysql.com/doc/refman/5.7/en/regexp.html" rel="nofollow ugc">MySQL Regexp syntax</a></li>
<li>Some characters will per default not work inside of the shortcode, see the “Caveats” section.</li>
<li>There are no bells and whistles for this plugin but it could potentionally be added in the futre.</li>
</ul>
<h3>Caveats</h3>
<p>Since the regex used by the plugin is specified as an attribute value inside of a shortcode, and the <a href="https://codex.wordpress.org/Shortcode_API" rel="nofollow ugc">Shortcode Api</a> disallows the use of certain characters which could be a part of a valid, useful regex, there are some things to consider.</p>
<blockquote>
<p>Attribute values must never contain the following characters:<br />
   * Square braces: [ ]<br />
   * Quotes: ” ‘</p>
<p>[ … ]<br />
  The recommended method of escaping special characters in shortcode attributes is HTML encoding. Most importantly, any user input appearing in a shortcode attribute must be escaped or stripped of special characters.</p>
</blockquote>
<ul>
<li>if in the regex you need to macth a character set <code>[a-z]</code>, then (following the shortcode Api documentation guidline), they need to be encoded. There are two encodings which the plugin accepts: “html” and “base64” </li>
<li>Currently there is no way to encode these things with help of the plugin, although it is planned for a future release, so the regexes must be encoded manually for now’<br />
For example, for regex <code>w[0u][0u]ti</code> can be expressed either:</li>
</ul>
<p>With HTML encoding:<br />
    <code>[gallery_from_regex_matches regex="w&#091;0u&#093;&#091;0u&#093;ti" encoding="html"]</code></p>
<p>With Base64 encoding:<br />
    <code>[gallery_from_regex_matches regex="d1swdV1bMHVddGk=" encoding="base64"]</code></p>
<p>To encode a string to base64, it can be done from the terminal like this:<br />
    <code>% echo -n "catsup" | base64<br />
Y2F0c3Vw<br />
% echo -n Y2F0c3Vw | base64 --decode<br />
catsup%</code></p>

Mixed Media Gallery Blocks

I selected this plug-in to replace the default gallery block. My primary interest was a grid that would include navigation arrows and a load more button. Both of these features work well and I would recommend this plug-in.

Great plugin
