我正在尝试为symfony中的单个字段定义多个条件,但每次我定义第二个条件时,它都会覆盖前一个条件。以下是我的代码示例:
# build query to fetch search results
$c = new Criteria();
# set minimum price
if($request->getPostParameter('price_from') > 0)
{
$c->add(HomeModelPeer::PRICE,
$request->getPostParameter('price_from'),
Criteria::GREATER_EQUAL);
}
# set maximum price
if($request->getPostParameter('price_to') > 0)
{
$c->add(HomeModelPeer::PRICE,
$request->getPostParameter('price_to'),
Criteria::LESS_EQUAL);
}
有没有办法为每个字段定义多个?

对于同时具有这两种限制的情况,您需要执行以下操作:
$c = new Criteria();
$c2 = $c->getNewCriterion(HomeModelPeer::PRICE,
$request->getPostParameter('price_from'),
Criteria::GREATER_EQUAL);
$c2->addAnd($c->getNewCriterion(HomeModelPeer::PRICE,
$request->getPostParameter('price_to'),
Criteria::LESS_EQUAL)
);
$c->add($c2);
