[Plugin: JSON API] Added a custom controller for querying WordPress options

Hello dphiffer, thank you for writing this great plugin!
I added a new controller that I needed for a project, for querying the WordPress options, for example the blogtitle. It can be downloaded at http://waywayway.nl/easyapp/wp-content/uploads/2012/05/json-api.1.0.7-plus-WPoptions-controller.zip

This controller must be activated in the WordPress dashboard: Settings > JSON API.

Example usage:

This URL: http://example.org/?json=options.get_options&options=blogname,show_on_front

For a blog with blogname ‘My blog name’ that has a page as the front page, not the usual list of posts, this outputs:

{
  "status": "ok",
  "blogname": "My blog name",
  "show_on_front": "page"
}

Changes:
– Added a file ‘options.php’ in folder ‘controllers’.
– Changed the plugin name in ‘json-api.php’ to ‘Plugin Name: JSON API – with WordPress options by http://waywayway.nl’, to make clear in the WordPress dashboard that the plugin is extended with a custom controller.

Content of ‘options.php’:

<?php

class JSON_API_options_Controller {

	// Get WordPress option settings from the options table, e.g. the blog name, see http://codex.wordpress.org/Option_Reference
    public function get_options() {
        global $json_api;
        $optionstring = $json_api->query->options;
	$optionarrayindexed = explode(',', $optionstring);

	foreach ($optionarrayindexed as $option) {
		$optionarrayassociative["$option"] = get_option($option);
	}

	if ($optionstring) {
	        return $optionarrayassociative;
	} else {
		$json_api->error("Include 'options' var in your request, options comma separated. See for a list of options: http://codex.wordpress.org/Option_Reference");
		return null;
	}

    }

}

?>
