Tested with: 2.4.1

print_r( kirby()->plugins );

My plugin list looked like this:

Array
(
    [category-checkboxes] => 1
    [controlledlist] => 1
    [kirby-crop-top] => 1
    [kirby-menu-editor] => 1
    [kirby-panel-prevnext] => 1
    [kirby-ratings] => 1
    [kirby-sitemap-query] => 1
    [load-assets] => 1
    [magic-number-format] => 1
    [modules] => 1
    [modules-field] => 1
    [previewer] => 1
)

If a plugin has been loaded

if( a::get( kirby()->plugins, 'modules' ) ) {
	echo 'The Modules plugin has been loaded';
}

Plugin loaded function

function pluginLoaded($plugin_name) {
  if( a::get( kirby()->plugins, 'modules' ) ) {
    return true;
  }
}

For the page Htaccess redirect to https non www I would like to add a code snippet for Htaccess redirect to https *and* www.

# Redirect http to https and add www.
# First rewrite to HTTPS:
# Don't put www. here. If it is already there it will be included, if not
# the subsequent rule will catch it.
RewriteCond %{HTTPS} off
RewriteRule .* https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
# Now, rewrite any request to the wrong domain to use www.
# [NC] is a case-insensitive match
RewriteCond %{HTTP_HOST} !^www\. [NC]
RewriteRule .* https://www.%{HTTP_HOST}%{REQUEST_URI} [L,R=301]

I agree that the url looks more nice without www, but in some cases adding www is a better option. For example, if using a url without www, all cookies will be sent to all subdomains. This can slow down access to images and js/css if you use a subdomain as a cdn for static content.

It's nice to be able to search replace with key value pair. It's not possible with a function like str::replace() but in PHP it's possible:

$string = strtr($string,
  array(
    'Search for this' => 'Replace with this',
    'Search something else' => 'Replace with something else'
    )
);

This snippet forces the Modules plugin to run. Perfect if your plugin is dependent of another plugin. Still, it will only run once, not again by the core.

kirby()->plugin('modules');

kirby()->routes(array(
  array(
    'pattern' => '(.+)',
    'action' => function($uri) {
      echo $uri;
    }
  )
));

When a bug is solved you could probably use (:all) instead.

https://forum.getkirby.com/t/get-plugin-config-values-without-providing-prefix-or-fallback/8706/6

In the config c::set('routes')

c::set('routes', array(
  array(
    'pattern' => 'my/awesome/(:any)',
    'action'  => function($uid) {
      echo $uid;
    }
  )
));

https://getkirby.com/docs/developer-guide/advanced/routing

In a plugin kirby()->routes()

kirby()->routes(array(
  array(
    'pattern' => 'my/awesome/(:any)',
    'action'  => function($uid) {
      echo $uid;
    }
  )
));

I prefer this version most of the times.

Consistant with registry $kirby->set('route')

$kirby->set('route', array(
  'pattern' => 'my/awesome/(:any)',
  'action'  => function($uid) {
    echo $uid;
  }
));

Internal use $router->register()

In most cases you probably will not need this syntax. Therefor I will not add an example of it here.

https://forum.getkirby.com/t/call-page-model-in-panel-field/7179/3

if( kirby()->plugin('modules') ) {
  echo 'Plugin has loaded';
}

It checks if the plugin has loaded.

Be aware!

If the plugin exists but has not been loaded it will force load it and return true if exists.

Hi! I followed the suggestion how to setup the .htaccess file (enable browser cache, compression etc.). The "Browser cache" part seems to produce some problems for me. I copied and pasted the code into my .htaccess file. The site works fine, but the panel does not. Suddenly, parts of the panel are not translated, I cannot rename pages (well in fact I can, but the change is not visible in the panel, although it is saved in the corresponding .txt file), newly created pages are not visible etc.

Has anybody faced similar issues? Clearing browser cache does not help. I use Kirby 3.
