CONTROLLER FILE: update_ctrl.php

Copy the below file  in your controller directory.


<?php
class update_ctrl extends CI_Controller{
function __construct(){
parent::__construct();
$this->load->model('update_model');
}
function show_student_id() {
$id = $this->uri->segment(3);
$data['students'] = $this->update_model->show_students();
$data['single_student'] = $this->update_model->show_student_id($id);
$this->load->view('update_view', $data);
}
function update_student_id1() {
$id= $this->input->post('did');
$data = array(
'Student_Name' => $this->input->post('dname'),
'Student_Email' => $this->input->post('demail'),
'Student_Mobile' => $this->input->post('dmobile'),
'Student_Address' => $this->input->post('daddress')
);
$this->update_model->update_student_id1($id,$data);
$this->show_student_id();
}
}
?>

MODEL FILE: update_model.php

Create new class in your model as shown below.


<?php
class update_model extends CI_Model{
// Function To Fetch All Students Record
function show_students(){
$query = $this->db->get('students');
$query_result = $query->result();
return $query_result;
}
// Function To Fetch Selected Student Record
function show_student_id($data){
$this->db->select('*');
$this->db->from('students');
$this->db->where('student_id', $data);
$query = $this->db->get();
$result = $query->result();
return $result;
}
// Update Query For Selected Student
function update_student_id1($id,$data){
$this->db->where('student_id', $id);
$this->db->update('students', $data);
}
}
?>

My SQL Code Segment:

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


CREATE DATABASE college;
CREATE TABLE students(
student_id int(10) NOT NULL AUTO_INCREMENT,
student_name varchar(255) NOT NULL,
student_email varchar(255) NOT NULL,
student_contact varchar(255) NOT NULL,
student_address varchar(255) NOT NULL,
PRIMARY KEY (student_id)
)
