当我使用过滤搜索日期范围时,日期格式为
2018年8月1日晚上7:30:00 但是我想要Y / m / d格式,但我不知道该怎么做,我的'filter_condition_callback'是`受保护的函数_filterSearchUpdatedAt($ collection,$ column) {
$value = $column->getFilter()->getValue();
if (isset($value['from'])) {
$from = $value['from'];
} else $from = '';
if (isset($value['to'])) {
$to = $value['to'];
} else $to = '';
if ($to != '' and $from != '') {
$collection->getSelect()->where("`cust`.`time_update` >=$from and `cust`.`time_update` <= $to");
} elseif ($from != '') {
$collection->getSelect()->where("`cust`.`time_update` >=$from");
} elseif ($to != '') {
$collection->getSelect()->where("`cust`.`time_update`<=$to");
}
$this->setCollection($collection);
return $this;
}`
