How to get plugin directory path from the theme layer class file of a plugin?

Question

I am trying to access an image that is located inside the plugin directory. How do I do it from the Theme layer that I have registered in this plugin?

Thanks.

Answer 1

in themes:

$theme_dir = dirname( __FILE__ ) . '/';

$theme_url = qa_opt('site_url') . 'qa-theme/' . qa_get_site_theme() . '/';

example: qa-theme.php

 

in other Layers add this variables and function to your layer:

var $plugin_directory;

var $plugin_url;

function qa_html_theme_layer($template, $content, $rooturl, $request)

{

global $qa_layers;

$this->plugin_directory = $qa_layers['Webmaster Layer']['directory'];

$this->plugin_url = $qa_layers['Webmaster Layer']['urltoroot'];

qa_html_theme_base::qa_html_theme_base($template, $content, $rooturl, $request);

}

example: qa-webmaster-layer.php

Note that it does not work if the user has not friendly URLs enabled under admin/general. See details here: https://github.com/q2a/question2answer/issues/122

Using "function qa_html_theme_layer()" will cause the PHP WARNING: "PHP Deprecated:  Methods with the same name as their class will not be constructors in a future version of PHP; layer_php has a deprecated constructor in \qa-include\qa-base.php(595) : eval()'d code on line 18". Use "QA_HTML_THEME_LAYER_URLTOROOT" instead.

Answer 2

Within the layer you can use the constant:

QA_HTML_THEME_LAYER_URLTOROOT

as described in the docs: http://www.question2answer.org/layers.php

With the qa-theme.php you can use: 

$this->rooturl
