Question

switch($kk)
{ 
    case 1:
        $flag=true;
        if ($month) 
        {
            echo"<pre>";   
            echo $select->where('start_date between "' . $year . '-' . $month . '-01" and "' . $year . '-' . $month . '-' . $this->daysInMonth($month, $year).'" and end_date between "' . $year . '-' . $month . '-01" and "' . $year . '-' . $month . '-' . $this->daysInMonth($month, $year).'"' );

        } 
        $select->order('start_date ASC');       
        break;

    case 2:
        $flag=true;
        if ($month) 
        {
            echo $select->where('start_date < "' . $year . '-' . $month . '-01"  and end_date between "' . $year . '-' . $month . '-01" and "' . $year . '-' . $month . '-' . $this->daysInMonth($month, $year).'"' );

        }
        $select->order('start_date ASC');
        break;

    case 3:
        $flag=true;
        if ($month) {
            echo $select->where('start_date between "' . $year . '-' . $month . '-01" and "' . $year . '-' . $month . '-' . $this->daysInMonth($month, $year).'" and end_date > "' . $year . '-' . $month . '-'.$this->daysInMonth($month, $year).'"' );
        }
        $select->order('start_date ASC');
        break;

    case 4:
        $flag=true;
        if ($month) {
            echo $select->where('start_date < "' . $year . '-' . $month . '-01" and end_date > "' . $year . '-' . $month . '-'.$this->daysInMonth($month, $year).'"' );
        }
        $select->order('start_date ASC');
        break;
}

$select->order('start_date ASC');此语句对元素进行排序。但它根据查询案例的结果进行排序。我需要一个排序查询来排序所有案例结果。我该怎么办？

Answer 1

你必须退出switch {}语句，它只在这种情况下执行什么。即使您将其置于默认值中：它也不会起作用，因为它可以单独处理案例或默认情况。我会在switch语句后创建一个条目。

验证您的switch case是否已执行，然后有另一个语句执行排序以应用于所有情况。
