Code for displaying latest two articles TOC

RCVSK · January 14, 2016, 11:46am

Hi all

I would like to include the latest two items published in the journal’s homepage. I know that a similar question has been asked before but mine does not have the complication of a feed from multiple Journals in to the main homepage…
We only have one Journal and I want the latest two items in this Journal’s homepage.

More precisely I want exactly what I see when I go to the current issue’s page (issue.tpl) but not taxonomised in sections; simply the latest two, regardless of the section (we have different article sections in our journal).

I started by copying the /templates/issue/issue.tpl to a new file (issue2.tpl), so I do not change the structure of the Current Issue page and then edited the /templates/index/journal.tpl file at the bottom to include my new file ({include file=“issue/issue2.tpl”}) instead of {include file=“issue/view.tpl”}.

The idea works great except I cannot modify the code to show me only the latest two articles, regardless of the sections; I am getting the full section-taxonomised list as in the Current Issue TOC…

I am fairly certain that there should be a simple code for that.

I would greatly appreciate any help on this. I am trying to go live on Monday…

Thanks
George

Hi @RCVSK,

Have a look at the PublishedArticleDAO’s getPublishedArticlesByJournalId function. This should allow you to get the most recent N articles, regardless of issue.

Hi Alec

thank you so much for coming back to me, and it sounds that this is the right direction… I tried a few things but I am a bit out of my depth… Is it possible to give me more detailed help/instructions. Really sorry to impose on your time but I have a feeling this may benefit a lot of people who would like to use it.

Thanks
George

Hi @RCVSK,

There’s an example of the use of this function here:

github.com

pkp/ojs/blob/ojs-dev-2_4/plugins/generic/webFeed/WebFeedGatewayPlugin.inc.php#L137


		if (!isset($typeMap[$type])) return false;

		// Get limit setting from web feeds plugin
		$displayItems = $webFeedPlugin->getSetting($journal->getId(), 'displayItems');
		$recentItems = (int) $webFeedPlugin->getSetting($journal->getId(), 'recentItems');

		$publishedArticleDao =& DAORegistry::getDAO('PublishedArticleDAO');
		if ($displayItems == 'recent' && $recentItems > 0) {
			import('lib.pkp.classes.db.DBResultRange');
			$rangeInfo = new DBResultRange($recentItems, 1);
			$publishedArticleObjects =& $publishedArticleDao->getPublishedArticlesByJournalId($journal->getId(), $rangeInfo, true);
			while ($publishedArticle =& $publishedArticleObjects->next()) {
				$publishedArticles[]['articles'][] =& $publishedArticle;
				unset($publishedArticle);
			}
		} else {
			$publishedArticles =& $publishedArticleDao->getPublishedArticlesInSections($issue->getId(), true);
		}

		$versionDao =& DAORegistry::getDAO('VersionDAO');
		$version =& $versionDao->getCurrentVersion();

I can’t guide through the modification in detail, but generally speaking, you’ll need to edit pages/index/IndexHandler.inc.php (which handles requests for the homepage) to assign the results of PublishedArticleDao::getPublishedArticlesByJournalId to the template manager. That’ll make it available from within the template file.

If you’re getting stuck somewhere specific, feel free to write it up.
