如何在codeigniter中检查行程开始日期和结束日期以及开始时间和结束时间

I am working on Booking system where a user can book their cars, before adding any trip inside the database/table I want to check the trip already exist between the dates and times. Here is my query inside my model.

$this->db->select('trId')
->from('trips')              
->where('carId',$data['carId'])//car Id
 ->where('tripStart <=',$data['tripStart'])//trip start date
->where('tripEnd >= ',$data['tripEnd'])//trip end date
->where('tripStartTime <= ',$data['tripStartTime'])//trip start time
->where('tripStartEnd >=',$data['tripStartEnd'])//trip end time
->get();

I have stored the values in my trips table is

tripStart = '2018-03-01'
tripEnd = '2018-03-03'
tripStartTime = '09:00:00'
tripStartEnd = '13:00:00'
select trId from trips 
where carId = value AND 
      (Between tripStart = "value" AND tripEnd = "value") AND
      (Between tripsStartTime = "value" AND tripStartEnd = "value");

This that What you want

Yes you can but before that you have to concate sql columns for comparing
Know SQL CONCAT

Also you need to combine your variables using into datetime using strtotime PHP function

<?php    
    $tripStart = '2018-03-01';
    $tripEnd = '2018-03-03';
    $tripStartTime = '09:00:00';
    $tripStartEnd = '13:00:00';

    $from = date('Y-m-d H:i:s',strtotime($tripStart.$tripStartTime));
    $to = date('Y-m-d H:i:s',strtotime($tripEnd.$tripStartEnd));

    $this->db->select('trId')
    ->from('trips')              
    ->where('carId',1)//car Id
    ->where("CONCAT(tripStart,'',tripStartTime) > ",$from)
    ->where("CONCAT(tripEnd,'',tripStartEnd) < ",$to)
    ->get();
?>
