Php 我想按日期获取数据

我想获取

数据

$form

到

$to

变量，该变量中存储了日期。因此，基本上我想从日期方面获取

数据

这是我的密码：

if ($_POST['data'] == 'paymentanalyticdata') {
    $criteria = new CDbCriteria;
    $criteria->join = 'LEFT OUTER JOIN payment_integration AS PI ON PI.name = t.payment_method AND PI.store_id=' . Yii::app()->session['store_id'];
    $criteria->select = 'PI.title as payment_method,sum(t.total) as total';
    $criteria->group = 'PI.title';
    $criteria->condition = 't.store_id=\'' . Yii::app()->session['store_id'] . '\'';

    $from = isset($_POST['from']) ? $_POST['from'] : '';
    $to = isset($_POST['to']) ? $_POST['to'] : '';
    if ($from != '' && $to != '') {
        $criteria->condition .= 't.entrydate';
    }
    $list = Order::model()->findAll($criteria);

    $categorylist = [];
    foreach ($list as $row) {
        $categorylist[] = array('PI' => $row->payment_method, 'total' => $row->total);
    }

    $seocount['paymentanalyticdata'] = $categorylist;
    echo json_encode($seocount);

我想在$criteria->condition中写入条件；
$criteria->condition .='????';
在这种情况下应该编写什么代码
 在

之间使用MySQL

，如下所示：-

$f=$_POST['from'];
$t=$_POST['to']
$criteria->condition .= 't.entrydate BETWEEN $f and $t';

您可以使用
addCondition
，类似于：

if ($from != '' && $to != '') {
    $criteria->addCondition('t.entrydate >= :startDate AND t.entrydate <= :endDate');
    $criteria->params = array(':startDate' => $from, ':endDate' => $to);
}

使用addBetweenCondition：

      if ($from != '' && $to != '') {
      $criteria->addBetweenCondition("entrydate", $from, $to);
 }

你能用commentHow打印MySQL查询和过去吗？我听不懂你的MySQL查询谢谢，但我只想使用条件，我应该在$criteria->condition中写些什么；我可以在KevinPatel上替换什么？不客气，如果有帮助，请接受答案。我是STACKOVERFLOW的新手，所以我不知道如何接受答案，所以请告诉我如何接受答案@克里斯托
      if ($from != '' && $to != '') {
      $criteria->addBetweenCondition("entrydate", $from, $to);
 }
