Getting Started
Please take note that CSS and jQuery 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
crud_oop.
3. After creating a database, click the SQL and paste the below codes. See image below for detailed instruction.
CREATE TABLE `member` (
`memberid` INT(11) NOT NULL AUTO_INCREMENT,
`firstname` VARCHAR(50) NOT NULL,
`lastname` VARCHAR(50) NOT NULL,
PRIMARY KEY(`memberid`)
) 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.
<?php
$conn = new mysqli("localhost", "root", "", "crud_oop");
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
?>
index.php
Our index that contains our sample table.
<?php
include('conn.php');
?>
