In this  tutorial we are going to explain you  how to perform CodeIgniter select query to fetch data from database using date range and ID.

In this demo we are  using input box and date selector. In input box you can enter an ID which you want to search and  using date selector you can search data for a particular date or for a date range.

Now one can easy find a records between the two given date ranges.

Watch our live demo or download the Script file from below link, extract files and run on your Local server.

Tutorial Scripts in detail

Below are the details of the code used in this tutorial with proper explanation.

My SQL Code Segment:

To create database and table, execute following codes in your My SQL.


//First create database
CREATE DATABASE `select_database`;
//Then create table
CREATE TABLE  `employee_info` (
`emp_id` int(11) NOT NULL AUTO_INCREMENT,
`emp_name` varchar(255) NOT NULL,
`emp_date_of_join` date NOT NULL,
`emp_address` varchar(255) NOT NULL,
`emp_mobile` varchar(255) NOT NULL,
PRIMARY KEY (`emp_id`)
)

 

Controllers : select_tutorial.php

copy the below code in your controller.

<?php

if (!defined('BASEPATH'))
