This tutorial will teach you the Basic Create, Read, Update and Delete Operations using PHP/MySQLi with Boostrap/Modal. Note: Bootstrap and Javascripts used in this tutorial are hosted so you need internet connection for them to work.

Creating our Database

First step is to create our database.
1. Open phpMyAdmin.
2. Click databases, create a database and name it as "sample".
3. After creating a database, click the SQL and paste the below code. See image below for detailed instruction.

  1. CREATE TABLE `user` (
  2.   `userid` INT(11) NOT NULL AUTO_INCREMENT,
  3.   `firstname` VARCHAR(30) NOT NULL,
  4.   `lastname` VARCHAR(30) NOT NULL,
  5.   `address` VARCHAR(100) NOT NULL,
  6. PRIMARY KEY(`userid`)
  7. ) ENGINE=InnoDB DEFAULT CHARSET=latin1;

Creating our Connection

Next, we create our connection to our database. This will serve as the bridge between our forms and database. We name this as conn.php.

  1. <?php
  2.  
  3. //MySQLi Procedural
  4. $conn = mysqli_connect("localhost","root","","sample");
  5. if (!$conn) {
  6. 	die("Connection failed: " . mysqli_connect_error());
  7. }
  8.  
  9. ?>

index.php

Next step is to create our sample table. This will be our Read.

addnew.php

This is our code in adding the data in our add form to our database.

  1. <?php
  2. 	include('conn.php');
  3.  
  4. 	$firstname=$_POST['firstname'];
  5. 	$lastname=$_POST['lastname'];
  6. 	$address=$_POST['address'];
  7.  
  8. 	mysqli_query($conn,"insert into user (firstname, lastname, address) values ('$firstname', '$lastname', '$address')");
  9. 	header('location:index.php');
  10.  
  11. ?>

edit.php

The code for our Update Form.

  1. <?php
  2. 	include('conn.php');
  3.  
  4. 	$id=$_GET['id'];
  5.  
  6. 	$firstname=$_POST['firstname'];
  7. 	$lastname=$_POST['lastname'];
  8. 	$address=$_POST['address'];
  9.  
  10. 	mysqli_query($conn,"update user set firstname='$firstname', lastname='$lastname', address='$address' where userid='$id'");
  11. 	header('location:index.php');
  12.  
  13. ?>

delete.php

Lastly, this our delete code to delete row in our table.

  1. <?php
  2. 	include('conn.php');
  3. 	$id=$_GET['id'];
  4. 	mysqli_query($conn,"delete from user where userid='$id'");
  5. 	header('location:index.php');
  6.  
  7. ?>
