Get Journals by Categories

Nazimm · June 28, 2015, 5:22am

Dear All,

I am trying to get/display Journals by Categories.

I believe we can add Jounal Category on Setup 1.1 but i cannot find samples or instructions on how to display journals by categories on the homepage.

Cheers!

Enabling and creating categories in the Site Admin creates a new menu bar item “Categories” and enables the the categorization of Journals in Journal Setup 1.1.

I believe the Categories page off of the menu bar only lists the Categories and the number of categorized journals. It sounds like you are wanting to mash-up the display of the Categories page and the homepage. One challenge will be that journals can be members of multiple categories.

See:

github.com

pkp/ojs/blob/ojs-stable-2_4_6/pages/search/SearchHandler.inc.php#L282


		$templateMgr =& TemplateManager::getManager();
		$templateMgr->assign_by_ref('results', $results);
		$templateMgr->display('search/titleIndex.tpl');
	}

	/**
	 * Display categories.
	 * @param $args array
	 * @param $request PKPRequest
	 */
	function categories($args, &$request) {
		$this->validate();
		$this->setupTemplate($request);

		$site =& $request->getSite();
		$journal =& $request->getJournal();

		$categoryDao =& DAORegistry::getDAO('CategoryDAO');
		$cache =& $categoryDao->getCache();

		if ($journal || !$site->getSetting('categoriesEnabled') || !$cache) {

@ctgraham

Thanks!

I got it with this code. This displays all the journals under category id 328

	$categoryId = 328;

	$this->validate();
	$this->setupTemplate($request, true, 'categoryList');

	$site =& $request->getSite();
	$journal =& $request->getJournal();

	$categoryDao =& DAORegistry::getDAO('CategoryDAO');
	$cache =& $categoryDao->getCache();

	if ($journal || !$site->getSetting('categoriesEnabled') || !$cache || !isset($cache[$categoryId])) {
		$request->redirect('index');
	}

	$journals =& $cache[$categoryId]['journals'];
