<p>W3 Total Cache and WP Super Cache are great caching plugins, but they do not know when a widget is updated.  WPEngine is the best place to host your WordPress installation, but their caching system is no smarter when it comes to updating widgets and menus.  I created this plugin because my website did not see any changes when saving widgets or menus using these caching systems.  Clear Cache For Me will purge ALL your cache each time you do a save without having to press an additional button.  It may be overkill, which may be why it’s not built in, but some people need simplicity.</p>
<p>In addition to clearing those pesky caching engines, Clear Cache for Me can force your browser to reload your current theme’s CSS and JS files.  I modify my theme’s CSS and JS files every so often and always have trouble with the browser not getting the latest version.  So now after clicking on the “Clear Cache Now!” button on the dashboard the browser will be forced to reload the current theme’s CSS and JS files.  If you do not click the “Clear Cache Now!” button, the browser will cache the CSS and JS files like it normally does.</p>
<p>The popular Qode themes has a options to set your own custom CSS and JS.  Sometimes you may not see your changes for a long while because your browser is trying to get the cached file.  Whenever you save your Qode’s options, the CSS and JS files will be forced to reload in the browser on the public side.</p>
<p>Works with the following caching plugins:</p>
<ul>
<li>Autoptimize</li>
<li>Breeze Cache</li>
<li>Cache Enabler</li>
<li>Cloudflare</li>
<li>GoDaddy Cache</li>
<li>Kinsta Cache</li>
<li>LiteSpeed Cache</li>
<li>Elementor (CSS cache)</li>
<li>Premium Addons for Elementor</li>
<li>SiteGround SuperCacher</li>
<li>Super Page Cache</li>
<li>WP Fastest Cache</li>
<li>WP Optimize Cache</li>
<li>WP Rocket</li>
<li>WP Super Cache</li>
<li>W3 Total Cache</li>
<li>WPEngine Cache</li>
</ul>
<p>Clears all cache for following actions (requires a caching system above to be active):</p>
<ul>
<li>When Widgets are saved.</li>
<li>When Customizer is saved.</li>
<li>When Menus are saved.</li>
<li>When a fields in Advanced Custom Fields are saved.</li>
<li>When a Contact Form 7 form is saved.</li>
<li>When a Formidable Form form is saved.</li>
<li>When WooThemes settings are saved.</li>
<li>When NextGen Gallery albums and galleries are updated (beta – may not clear cache on all actions).</li>
<li>When Qode options are saved this plugin forces browsers to reload the custom css and custom js.</li>
<li>When a WP Forms forms or settings are saved.</li>
<li>When WooCommerce settings are saved. (Cache should already be clearing when products are saved.)</li>
<li>When settings from the Insert Headers and Footers plugin by WPBeginner are saved.  </li>
<li>When Settings from a settings page is saved.  This includes settings from WordPress core, Yoast SEO, and most other plugins using the Settings API.</li>
<li>When WordPress is updated.</li>
<li>When plugins are updated, activated, and deactivated.</li>
<li>When WordPress, plugins, and themes are automaticallly updated.</li>
</ul>

<p>Note:  Since some caching systems run in the <code>shutdown</code> hook, this plugin also runs in that hook.  This means if PHP does not have enough time, some code including any hooks within the <code>ccfm_clear_cache_for_all()</code> function are not guaranteed to run.  If you need code to run, consider using the <code>ccfm_clear_cache_for_me_setup</code> hook.</p>
<p>Some plugins may have “auto purge” (like Cloudflare), but it doesn’t cover all the items this plugin covers.</p>
<h3>Developer Options</h3>
<h4>ccfm_supported_caching_exists</h4>
<p>Use this filter to determine if this plugin should do anything including showing the button on the dashboard.  Return true if a caching system is supported.<br />
Default: True if any of the supported caching systems is active.<br />
See Example 1 below.</p>
<h4>ccfm_admin_init or ccfm_init_actions</h4>
<p>Use this action to add hooks when cache is to be cleared.  Or do any other setup activity.</p>
<h4>ccfm_clear_cache_for_me_before</h4>
<p>Use this action to clear cache from an unsupported caching system before the default caching systems clear their cache.</p>
<h4>ccfm_clear_cache_for_me</h4>
<p>Use this action to clear cache from an unsupported caching system after the default caching systems clear their cache.</p>
<h4>Example</h4>
<p>If you were using an unsupported caching system you’ll need to identify the caching plugin’s class or function which clears the cache.  As an example, if the unsupported caching system called the <code>MyOtherCache::clear_all()</code> function, you would use the following code to get this plugin to clear the cache.</p>
<pre><code><?php
function my_other_cache_enable( $return = false ) {
    if ( class_exists( 'MyOtherCache' ) )
        return true;
    return $return;
}
add_filter('ccfm_supported_caching_exists', 'my_other_cache_enable');

function my_other_cache_clear() {
    if ( my_other_cache_enable() )
        MyOtherCache::clear_all();
}
add_action('ccfm_clear_cache_for_me', 'my_other_cache_clear');
</code></pre>

<p>WP Engine GeoTarget integrates with the variables on your WP Engine site to display content catered to the visitor’s location. With the ability to access variables from as broad as country to as specific as latitude and longitude, your website can now display geographically relevant content.</p>
<h4>Geo-Marketing</h4>
<ul>
<li>Create marketing campaigns targeted only at certain locations.</li>
</ul>
<h4>Localization</h4>
<ul>
<li>Redirect incoming traffic to content in the local language or currency.</li>
<li>Businesses with local branches can direct customers to a relevant physical location or local microsite.</li>
</ul>
<h4>Ecommerce</h4>
<ul>
<li>Filter out merchandise or services that are not available in a certain locale.</li>
<li>Display country-specific shipping, tax, or sales information.</li>
</ul>
<h4>Legal Requirements</h4>
<ul>
<li>Filter required legal notices from countries for whom those notices may not be relevant.</li>
</ul>
<h4>* Please Note *</h4>
<p>Customers on Premium and Enterprise plans can use this plugin at no additional cost. If you are on another plan type and would like to use GeoTarget on one of your sites, you can add it to your plan <a href="http://wpengine.com/plans/?utm_source=wpengine-geoip" rel="nofollow ugc">here</a>. This will not function outside of the WP Engine environment.</p>
<h3>Location Variable Shortcodes</h3>
<p>You can use any of the following location variable shortcodes to return the various geographic location the user is visiting your site from:</p>
<p>1) Continent: <code>[geoip-continent]</code></p>
<p>2) Country: <code>[geoip-country]</code></p>
<p>3) Region: <code>[geoip-region]</code></p>
<ul>
<li>In the US region will return States</li>
<li>In Canada region will return Provinces</li>
<li>Outside the US/CA this will return a Region number. Please note region numbers are not unique between countries</li>
</ul>
<p>4) City: <code>[geoip-city]</code></p>
<p>5) Postal Code: <code>[geoip-postalcode]</code></p>
<ul>
<li>This variable is only available in the US due to limitations with the location data GeoTarget uses</li>
</ul>
<p>6) Latitude: <code>[geoip-latitude]</code></p>
<p>7) Longitude: <code>[geoip-longitude]</code></p>
<p>8) Location: <code>[geoip-location]</code></p>
<h4>Example</h4>
<pre><code>Hi, and welcome to [geoip-city]! The place to be in [geoip-region],[geoip-country].
</code></pre>
<p>A visitor from Austin, Texas would see the following:<br />
    Hi, and welcome to Austin! The place to be in TX, US.</p>
<h3>Localized Content</h3>
<pre><code>[geoip-content country="US"]Your US specific content goes here[/geoip-content]
</code></pre>
<p>The content shortcode allows you to hide or show specific content based on visitor geographies:</p>
<p>Below are all the supported geography options, this allows to you SHOW content for only specific locations:</p>
<ul>
<li>continent</li>
<li>country</li>
<li>areacode</li>
<li>region</li>
<li>city</li>
<li>postalcode</li>
</ul>
<p>Below are all the supported negative geography options, this allows to you HIDE content for only specific locations:</p>
<ul>
<li>not_continent</li>
<li>not_country</li>
<li>not_areacode</li>
<li>not_region</li>
<li>not_city</li>
<li>not_postalcode</li>
</ul>
<h4>Examples of the Content Shortcode</h4>
<p>This will display “Content just for US visitors” strictly for visitors viewing from the United States.</p>
<pre><code>[geoip-content country="US"] Content just for US visitors [/geoip-content]
</code></pre>
<p>This will display “Content just for everyone in Texas and California” strictly for visitors from Texas and California.</p>
<pre><code>[geoip-content region="TX, CA."] Content just for everyone in Texas and California [/geoip-content]
</code></pre>
<p>You can mix and match geography and negative geography options to create verbose logic in a single shortcode:</p>
<pre><code>[geoip-content country="US" not_city="Austin"]Content for US visitors but not for visitors in Austin[/geoip-content]
</code></pre>
<h4>Limitations</h4>
<p>There is a single limitation in the logic that lets you filter content for multiple geographic areas.</p>
<p>You can progressively limit the area that content is shown in. But once your content is hidden from an area, a subset of that area can’t be added back in.</p>
<p>For example,<br />
If I limit my content to Europe, then limit my content from Great Britain, I can’t go back and show it to London.</p>
<h4>Creative Work Arounds</h4>
<h3>Limit content to some regions of a country (or some cities of a state)</h3>
<p>You want to show an offer for free shipping to every state in the US <em>but</em> Alaska and Hawaii. You may be inclined to write something like</p>
<p><strong>BAD</strong></p>
<pre><code>[geoip-content country="US" not_state="AK, HI"]Lorem ipsum dolor sit amet[/geoip-content]
</code></pre>
<p>Instead, show it to all other 48 states</p>
<p><strong>GOOD</strong></p>
<pre><code>[geoip-content state="AL, AZ, AR, CA, CO, CT, DE, FL, GA, ID, IL, IN, IA, KS, KY, LA, ME, MD, MA, MI, MN, MS, MO, MT, NE, NV, NH, NJ, NM, NY, NC, ND, OH, OK, OR, PA, RI, SC, SD, TN, TX, UT, VT, VA, WA, WV, WI, WY"]Free shipping on all orders over $50![/geoip-content]
</code></pre>
<h3>Duplicate location names</h3>
<p>You want to show discount airfare on a flight to Paris, France. The content should show to all of the US and France, but not Paris itself.</p>
<p><strong>BAD</strong></p>
<pre><code>[geoip-content country="US, FR" not_city="Paris"]Fly to Paris for only $199![/geoip-content]
</code></pre>
<p>The problem here is that Paris, Texas will be hidden. The solution? Just have two geoip-content shortcodes.</p>
<p><strong>GOOD</strong></p>
<pre><code>[geoip-content country="FR" not_city="Paris"]Fly to Paris for only $199![/geoip-content][geoip-content country="US"]Fly to Paris for only $199![/geoip-content]
</code></pre>
<h3>Adding an area into an omitted region</h3>
<p>You want to show an ad written in Spanish to all of South America except for Brazil. Brasilia, however, has enough Spanish speakers that you want to include Brasilia.</p>
<p><strong>BAD</strong></p>
<pre><code>[geoip-content continent="SA" not_country="BR" city="Brasilia"]Lorem ipsum dolor sit amet[/geoip-content]
</code></pre>
<p><strong>GOOD</strong></p>
<pre><code>[geoip-content continent="SA" not_country="BR"]Venta de la Navidad en los adaptadores USB[/geoip-content]



[geoip-content city="Brasilia"]Venta de la Navidad en los adaptadores USB[/geoip-content]
</code></pre>
<h3>Calculate distance between points</h3>
<p>You have a utility function that will calculate the distance from your provided lat/lng coordinate to the visitor’s location in either miles or kilometers. This can be useful for determining approximate distances, as results may be cached at the state or country level, depending on your configuration.</p>
<p>Example use:</p>
<pre><code>$latitude  = 30.268246;
$longitude = -97.745992;
$geo = WPEngine\GeoIp::instance();
if ( false !== $geo->distance_to( $latitude, $longitude ) ) {
    $miles_to_wp_engine = $geo->distance_to( $latitude, $longitude );
}
</code></pre>
<h3>Testing Parameters</h3>
<p>You can use the following URL parameters to test how your localized content will appear to visitors from various geographic locations. You can add any of the parameters below to any URL of a page using the GeoTarget shortcodes or API calls:</p>
<p>Spoof visitor from the state of Texas:</p>
<pre><code>yourdomain.com/?geoip&region=TX
</code></pre>
<p>Spoof visitor from the United States:</p>
<pre><code>yourdomain.com/?geoip&country=US
</code></pre>
<p>Spoof visitor from Austin, Texas</p>
<pre><code>yourdomain.com/?geoip&city=Austin
</code></pre>
<p>Spoof visitor from the U.S. zip code 78701:</p>
<pre><code>yourdomain.com/?geoip&zip=78701
</code></pre>
<p>Please note: full page redirects and TLD redirects still need to be implemented with the necessary API calls.</p>


WP Engine GeoTarget

After having spent few hours trying to work the plugin's WPEngine\GeoIp::distance_to() method I found that the code has logical bug which caused the return of wrong values.

For a product WP Engine is charging $30 / month this is not acceptable. I contacted the WP Engine support, but they said they do not offer development support, hmmm, okay!

Plugin does not work as expected

Create a personalized user experience based on location.
