Its a simple student entry form and listing of the entered students.You can follow the below steps to do this
Step1: create a database named (studentdatabase) in the mysql using phpmyadmin. Below query u can execute through phpmyadmin
|
1 2 3 4 5 6 7 8 9 10 11 12 |
CREATE TABLE IF NOT EXISTS `tbl_student` ( `id` int(11) NOT NULL, `studentname` varchar(250) NOT NULL, `email` varchar(250) NOT NULL, `phone` int(11) NOT NULL ) ENGINE=MyISAM DEFAULT CHARSET=latin1; ALTER TABLE `tbl_student` ADD PRIMARY KEY (`id`); ALTER TABLE `tbl_student` MODIFY `id` int(11) NOT NULL AUTO_INCREMENT; |
Step2: Configuration changes in different pages.
In Application/config/routes.php
$route[‘default_controller’] = “register”;
default_controller will be a “welcome” controller in a fresh codeigniter. here i m changed the default_controller to register.
In Application/config/database.php
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 |
<?php $db['default']['hostname'] = 'localhost'; $db['default']['username'] = 'root'; $db['default']['password'] = ''; $db['default']['database'] = 'studentdatabase'; $db['default']['dbdriver'] = 'mysql'; $db['default']['dbprefix'] = ''; $db['default']['pconnect'] = TRUE; $db['default']['db_debug'] = TRUE; $db['default']['cache_on'] = FALSE; $db['default']['cachedir'] = ''; $db['default']['char_set'] = 'utf8'; $db['default']['dbcollat'] = 'utf8_general_ci'; $db['default']['swap_pre'] = ''; $db['default']['autoinit'] = TRUE; $db['default']['stricton'] = FALSE; ?> |
In Application/config/config.php
changed the base_url as like below. if you are running the application inside htdocs folder of XAMPP or WAMP server,can give any name for the folder. here the name of the folder is ‘school’.
|
1 |
<?php $config['base_url'] = 'http://localhost/school/'; ?> |
In Application/config/autoload.php
|
1 2 3 4 |
<?php $autoload['libraries'] = array('form_validation','database','session'); $autoload['helper'] = array('url','form'); $autoload['model'] = array('student_model'); ?> |
above mentioned helpers,model and libraries are used in the application.

Step3: Creation of controller. here i created a controller called register.php. path of this file will be inside application/controller/register.php

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 |
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed'); class Register extends CI_Controller { public function index() { $this->load->view('register/register_main'); } public function regstudent() { $this->load->view('register/register_student'); } public function liststudent() { $disp_data['student_details']=$this->student_model->student_list(); $this->load->view('register/list_student',$disp_data); } public function student_submit() { $this->form_validation->set_rules('student_name', 'Student name', 'trim|required'); $this->form_validation->set_rules('student_email', 'Student Email', 'trim|required'); $this->form_validation->set_rules('student_phone', 'Student Phone', 'trim|required'); if ($this->form_validation->run() == FALSE) { $this->load->view('register/register_student'); } else { $student_name = $this->input->post('student_name',TRUE); $student_email = $this->input->post('student_email',TRUE); $student_phone = $this->input->post('student_phone',TRUE); $insert_student_array = array( 'studentname' => $student_name, 'email' => $student_email, 'phone' => $student_phone, ); $this->student_model->insert_student($insert_student_array); $this->session->set_flashdata('success_msg', 'success fully entered details'); $this->load->view('register/register_student'); } } } |
Step4:View file creation-created three view files inside views/register folder
Three view files usage and code as below
register_main.php- This is used to display the main page of the application. This is a simple html page layout to display the student add,student list links
