Hello, I´m new with typo3 amd fluid, I need a little help with this issue:
I have the paginateController like this:
class PaginateController extends
\TYPO3\CMS\Fluid\Core\Widget\AbstractWidgetController {
protected $configuration = array('itemsPerPage' => 10, 'insertAbove' => FALSE,
'insertBelow' => TRUE, 'maximumNumberOfLinks' => 99, 'addQueryStringMethod' => '');
/**
* @var \TYPO3\CMS\Extbase\Persistence\QueryResultInterface
*/
protected $currentPage = 1;
protected $maximumNumberOfLinks = 99;
protected $numberOfPages = 1;
public function initializeAction() {
$this->objects = $this->widgetConfiguration['objects'];
\TYPO3\CMS\Core\Utility\ArrayUtility::mergeRecursiveWithOverrule($this->configuration,
$this->widgetConfiguration['configuration'], FALSE);
$this->numberOfPages = ceil(count($this->objects) /
(int)$this->configuration['itemsPerPage']);
$this->maximumNumberOfLinks =
(int)$this->configuration['maximumNumberOfLinks'];
}
/**
* @param integer $currentPage
* @return void
*/
public function indexAction($currentPage = 1) {
// set current page
$this->currentPage = (int)$currentPage;
if ($this->currentPage < 1) {
$this->currentPage = 1;
}
if ($this->currentPage > $this->numberOfPages) {
// set $modifiedObjects to NULL if the page does not
exist
$modifiedObjects = NULL;
} else {
// modify query
$itemsPerPage =
(int)$this->configuration['itemsPerPage'];
$query = $this->objects->getQuery();
$query->setLimit($itemsPerPage);
if ($this->currentPage > 1) {
$query->setOffset((int)($itemsPerPage *
($this->currentPage - 1)));
}
$modifiedObjects = $query->execute();
}
$this->view->assign('contentArguments', array(
$this->widgetConfiguration['as'] => $modifiedObjects
));
$this->view->assign('configuration', $this->configuration);
$this->view->assign('pagination', $this->buildPagination());
}
/**
* If a certain number of links should be displayed, adjust before and
after
* amounts accordingly.
*
* @return void
*/
protected function calculateDisplayRange() {
$maximumNumberOfLinks = $this->maximumNumberOfLinks;
if ($maximumNumberOfLinks > $this->numberOfPages) {
$maximumNumberOfLinks = $this->numberOfPages;
}
$delta = floor($maximumNumberOfLinks / 2);
$this->displayRangeStart = $this->currentPage - $delta;
$this->displayRangeEnd = $this->currentPage + $delta -
($maximumNumberOfLinks % 2 === 0 ? 1 : 0);
if ($this->displayRangeStart < 1) {
$this->displayRangeEnd -= $this->displayRangeStart - 1;
}
if ($this->displayRangeEnd > $this->numberOfPages) {
$this->displayRangeStart -= $this->displayRangeEnd -
$this->numberOfPages;
}
$this->displayRangeStart = (int)max($this->displayRangeStart,
1);
$this->displayRangeEnd = (int)min($this->displayRangeEnd,
$this->numberOfPages);
}
/**
* Returns an array with the keys "pages", "current", "numberOfPages", "nextPage"
& "previousPage"
*
* @return array
*/
protected function buildPagination() {
$this->calculateDisplayRange();
$pages = array();
for ($i = $this->displayRangeStart; $i <=
$this->displayRangeEnd; $i++) {
$pages[] = array('number' => $i, 'isCurrent' => $i ===
$this->currentPage);
}
$pagination = array(
'pages' => $pages,
'current' => $this->currentPage,
'numberOfPages' => $this->numberOfPages,
'displayRangeStart' => $this->displayRangeStart,
'displayRangeEnd' => $this->displayRangeEnd,
'hasLessPages' => $this->displayRangeStart > 2,
'hasMorePages' => $this->displayRangeEnd + 1 <
$this->numberOfPages
);
if ($this->currentPage < $this->numberOfPages) {
$pagination['nextPage'] = $this->currentPage + 1;
}
if ($this->currentPage >1) {
$pagination['previousPage'] = $this->currentPage-1;
}
return $pagination;
}
}
In my action html file I have this fragment to paginate query results
<f:if condition="{items->f:count()} > {limit}">
<f:then>
<f:widget.paginate objects="{items}" as="item" configuration="{itemsPerPage: limit, maximumNumberOfLinks: 7}">
<f:for each="{item}" as="i" iteration="iter">
<div
class="famName">{i.taxon.taxonPadre.nombre}</div>
<f:render section="singleItem"
arguments="{elm:i}"/>
</f:for>
</f:widget.paginate>
</f:then>
<f:else>
<f:for each="{items}" as="i" iteration="iter">
<div class="famName">{i.taxon.taxonPadre.nombre}</div>
<f:render section="singleItem"
arguments="{elm:i}"/>
</f:for>
</f:else>
</f:if>
Paginator works fine at the fist time the results page is loaded since first
page is displayed, I can navigate through the other pages with the pagination
links, but when I clicked the link 1 to back to the first page, the link
doesn´t point out to first page, href attribute is set with the url and its
currentPage argument has the number of current page instead of currentPage=1,
then I can´t return to first page.
Please, let me know if the controller need something else, or if I have to do
something extra in the configuration.
Angie.
