<p>In WordPress 3.0 and later, <a href="https://core.trac.wordpress.org/changeset/14996" rel="nofollow ugc">a default filter</a> changes all instances of “WordPress” (note the small “p”) in posts, titles, and comments to “WordPress”. <a href="https://core.trac.wordpress.org/ticket/13583" rel="nofollow ugc">For various reasons</a>, such as preserving spelling in existing posts and comments, a blog owner may want to turn this filter off. That is what this plugin does.</p>
<p>Simply upload the plugin files to your WordPress plugins folder, activate it on your blog’s Plugin administration page, and you are set!</p>
<h3>Technical Details</h3>
<p>This plugin seeks to disable the capital_P_dangit function, which is the WordPress function that disallows “WordPress” to be used on blogs.</p>
<p>The filter is defined in <a href="https://core.trac.wordpress.org/browser/trunk/src/wp-includes/default-filters.php" rel="nofollow ugc">wp-includes/default-filters.php</a> and is applied in <a href="https://core.trac.wordpress.org/browser/trunk/src/wp-includes/formatting.php" rel="nofollow ugc">wp-includes/formatting.php</a> of the core WordPress code.</p>
<p>The remove_filter function is used in this plugin to undo the add_filter function applied in wp-includes/formatting.php. In versions 1.0 and 1.1 of this plugin, the function was removed for certain priority levels. As of version 1.2, this plugin removes the filter for all possible priority levels. Thanks to <a href="http://subscribe2.wordpress.com/" rel="nofollow ugc">Matt Robinson</a> for suggesting this method and providing code that is used in the plugin.</p>
<p>For more information regarding how this function is applied in WordPress, the following are the relevant changesets to the core WordPress code regarding this function:</p>

Remove WordPress to WordPress filter

Brilliant

This turns off the default filter that changes all instances of "Wordpress" to "WordPress".

<h4>🧩 Shortcode</h4>
<ul>
<li>In editor <code>[br_filters attribute=price type=slider title="Price Filter"]</code></li>
<li>In PHP <code>do_shortcode('[br_filters attribute=price type=slider title="Price Filter"]');</code></li>
</ul>
<h4>⚙️ Shortcode Options:</h4>
<ul>
<li><code>attribute</code>(required) – product attribute, e.g. price or length. Don’t forget that WooCommerce adds the pa_ suffix for created attributes.<br />
So if you create a new attribute <code>jump</code>, its name is <code>pa_jump</code></li>
<li><code>type</code>(required) – checkbox, radio, slider or select</li>
<li><code>operator</code> – OR or AND</li>
<li><code>title</code> – whatever you want to see as a title. Can be empty</li>
<li><code>product_cat</code> – parent category id</li>
<li><code>cat_propagation</code> – should we propagate this filter to child categories? Set 1 to turn this on</li>
<li><code>height</code> – max filter box height. When height is met, the scroll will be added</li>
<li><code>scroll_theme</code> – used if height is set and actual height of the box is more</li>
</ul>


Advanced AJAX Product Filters

Perfect!


Does the job and is relatively easy to administer...


Nice plugin


The plugin works well but the confusing UI could be corrected. I wasted more than an hour setting up filters of product categories only to notice that they had to be set up as a filter of tags. Otherwise they will only show up on the shop page


A bit confusing to use but works fine

Fast and flexible AJAX product filters for WooCommerce. Filter by categories, attributes, price, tags, rating, and more. No page reloads.
