Show more issues on homepage

fesp · April 25, 2017, 1:04pm

Currently, the journal homepage shows the current issue. After reading this forum, I found it will require modification of the code to show more recent issues. I am using Open Journal Systems 2.4.8.0. Please suggest what code I should add. Thank you.

Currently the index handler select the current issue for display here:

github.com

pkp/ojs/blob/ojs-2_4_8-0/pages/index/IndexHandler.inc.php#L53-L73


      
          			$displayCurrentIssue = $journal->getSetting('displayCurrentIssue');
          			$issueDao =& DAORegistry::getDAO('IssueDAO');
          			$issue =& $issueDao->getCurrentIssue($journal->getId(), true);
          			if ($displayCurrentIssue && isset($issue)) {
          				import('pages.issue.IssueHandler');
          				// The current issue TOC/cover page should be displayed below the custom home page.
          				IssueHandler::_setupIssueTemplate($request, $issue);
          			}
          
          			$enableAnnouncements = $journal->getSetting('enableAnnouncements');
          			if ($enableAnnouncements) {
          				$enableAnnouncementsHomepage = $journal->getSetting('enableAnnouncementsHomepage');
          				if ($enableAnnouncementsHomepage) {
          					$numAnnouncementsHomepage = $journal->getSetting('numAnnouncementsHomepage');
          					$announcementDao =& DAORegistry::getDAO('AnnouncementDAO');
          					$announcements =& $announcementDao->getNumAnnouncementsNotExpiredByAssocId(ASSOC_TYPE_JOURNAL, $journal->getId(), $numAnnouncementsHomepage);
          					$templateMgr->assign('announcements', $announcements);
          					$templateMgr->assign('enableAnnouncementsHomepage', $enableAnnouncementsHomepage);
          				}
          			}
          			$templateMgr->display('index/journal.tpl');

It is passed off to the template index/journal.tpl, which displays the issue’s detail with this call:

github.com

pkp/ojs/blob/ojs-2_4_8-0/templates/index/journal.tpl#L49


      
          				<td><a href="{url page="announcement"}">{translate key="announcement.moreAnnouncements"}</a></td>
          			</tr>
          		</table>
          	</div>
          {/if}
          
          {if $issue && $currentJournal->getSetting('publishingMode') != $smarty.const.PUBLISHING_MODE_NONE}
          	{* Display the table of contents or cover page of the current issue. *}
          	<br />
          	<h3>{$issue->getIssueIdentification()|strip_unsafe_html|nl2br}</h3>
          	{include file="issue/view.tpl"}
          {/if}
          
          {include file="common/footer.tpl"}

Which brings in the issue template:

To make this display more than one issue, you would need to iterate over the issues, similar to the way that the site homepage would iterate over the journals:

github.com

pkp/ojs/blob/ojs-2_4_8-0/templates/index/site.tpl#L28-L49


      
          {iterate from=journals item=journal}
          	{if $site->getSetting('showThumbnail')}
          		{assign var="displayJournalThumbnail" value=$journal->getLocalizedSetting('journalThumbnail')}
          		<div style="clear:left;">
          		{if $displayJournalThumbnail && is_array($displayJournalThumbnail)}
          			{assign var="altText" value=$journal->getLocalizedSetting('journalThumbnailAltText')}
          			<div class="homepageImage"><a href="{url journal=$journal->getPath()}" class="action"><img src="{$journalFilesPath}{$journal->getId()}/{$displayJournalThumbnail.uploadName|escape:"url"}" {if $altText != ''}alt="{$altText|escape}"{else}alt="{translate key="common.pageHeaderLogo.altText"}"{/if} /></a></div>
          		{/if}
          		</div>
          	{/if}
          	{if $site->getSetting('showTitle')}
          		<h3>{$journal->getLocalizedTitle()|escape}</h3>
          	{/if}
          	{if $site->getSetting('showDescription')}
          		{if $journal->getLocalizedDescription()}
          			<div class="journalDescription" id="journalDescription-{$journal->getId()|escape}">
          				{$journal->getLocalizedDescription()|nl2br}
          			</div>
          		{/if}
          	{/if}

The journals iterator is constructed here:

github.com

pkp/ojs/blob/ojs-2_4_8-0/pages/index/IndexHandler.inc.php#L95-L103


      
          			$journals =& $journalDao->getJournals(
          				true,
          				$rangeInfo,
          				$searchInitial?JOURNAL_FIELD_TITLE:JOURNAL_FIELD_SEQUENCE,
          				$searchInitial?JOURNAL_FIELD_TITLE:null,
          				$searchInitial?'startsWith':null,
          				$searchInitial
          			);
          			$templateMgr->assign_by_ref('journals', $journals);
