我正在使用 codeigniter 为客户建立一个租赁网站。仅当没有租赁期与我的查询匹配时,我才尝试返回 true。基本上有一张出租表,上面有开始日期和结束日期。
我的客户从日期选择器中选择开始日期,结束日期是开始日期后的固定天数。
因此,我想了解在这些日期是否有任何出租物品正在出租,以验证客户是否可以预订该物品。这是我到目前为止所拥有的,我需要使用 Codeigniters 活动记录来完成这一点......
function check_product($periodLength) {
//This is the start time they chose from the picker
$startTime = $_POST['date'];
//The period length is a variable of days, so the end date would be their chosen start date plus a certain amount of days...
$endTime = strtotime('+'.$periodLength.'day', $startTime);
$this->db->where('productsId', $_POST['productId']);
//This is where I need help!!! What query would give me records that are NOT between the start and end dates that i'm wanting
$query = $this->db->get('rentals');
$data = array();
foreach ($query->result() as $row) {
$data[] = array(
'id' => $row->id,
'customerId' => $row->customerId,
'productsId' => $row->productsId,
'periodStart' => $row->periodStart,
'periodEnd' => $row->periodEnd,
'status' => $row->status,
'specialInstructions' => $row->specialInstructions,
'adminNotes' => $row->adminNotes
);
}
return $data;
}
我确定我的大部分问题都在我的脑海中,但我需要弄清楚我的开始日期到结束日期期间是否已经保留。
