[英]Remove empty arrays from array
我有 ajaxlistAction:
public function ajaxlistAction()
{
$em = $this->getDoctrine()->getEntityManager();
$qb = $em->createQueryBuilder();
$qb->select('wfsd','b')
->from('TFTDataBundle:WpFormSubmittedData','wfsd')
->leftjoin('wfsd.customFieldData','b')
->leftjoin('b.custom_field','CustomField')
->getQuery()->getResult();
if (!empty($_GET['sSearch'])) {
$qb->andWhere('b.data like :search')->setParameter('search', "%{$_GET['sSearch']}%");
}
$qc = clone ($qb);
$qc->select('COUNT( DISTINCT b.id)');
$count = $qc->getQuery()->getSingleScalarResult();
$columns = array('CustomField.fieldLabel');
if( isset($_GET['iSortCol_0'] )){
$dir = empty($_GET['sSortDir_0'])?'asc':$_GET['sSortDir_0'];
$qb->orderBy($columns[$_GET['iSortCol_0']], $dir );
}
if (empty($_GET['iDisplayLength'])) {
$_GET['iDisplayLength'] = 10;
}
if (empty($_GET['sEcho'])) {
$_GET['sEcho'] = 1;
}
if (!empty($_GET['iDisplayStart'])) {
$qb->setFirstResult($_GET['iDisplayStart']);
}
$qb->setMaxResults($_GET['iDisplayLength']);
$data = array();
foreach($qb->getQuery()->getResult() as $row ) {
$rows = array();
foreach ($row->getCustomFieldData() as $customFieldData) {
$rows[] = $customFieldData->getData();
}
$data[] = $rows;
}
//$data = $qb->getQuery()->getArrayResult();
return new JsonResponse(array("sEcho"=>$_GET['sEcho'],"iTotalRecords"=>$count,"iTotalDisplayRecords"=>$count,'aaData'=>$data));
}
這個動作的反應是這樣的
{"sEcho":"1","iTotalRecords":"44","iTotalDisplayRecords":"44","aaData":[[],[],[],[],[],[],[],["Name","email@domain.co","this is subject","this is message"],["sdsd","sas@ggkm.com","asa","sdsd"],["sdsd","sas@ggkm.com","asa","sdsd"]]}
我想刪除空數組並想要這樣的輸出
{"sEcho":"1","iTotalRecords":"44","iTotalDisplayRecords":"44","aaData":[["Name","email@domain.co","this is subject","this is message"],["sdsd","sas@ggkm.com","asa","sdsd"],["sdsd","sas@ggkm.com","asa","sdsd"]]}
我怎樣才能刪除上面的空數組?
請幫我從結果數組中刪除這些子數組
謝謝
您可以更改此行:
$data[] = $rows;
對此:
if( count($rows) > 0)
$data[] = $rows;
這將檢查$rows
是否不是空數組,然后將其推入$data
數組
