PHP code not inserting data using "INSERT INTO"

PHP
1

I am following the Jump Start PHP book from sitepoint and I am trying to input user details into a table called “user” in my database called “kickstartapp”

This is the PHP code that I have copied exactly from the book. I run the code in my browser but upon checking the phpMyAdmin there are no details in the “users” table.

 <?php
$db = new PDO("mysql:host=localhost; dbname=kickstartapp", "USERNAME", "PASSWORD");
$db->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
try {
	$queryStr = "INSERT INTO users (username, password, email) VALUES ('admin', MD5('admin'), 'youremail@domain.com')";
		$db->query($queryStr);
} catch (PDOException $e) {
	echo $e->getMessage();
	}
	
?>

Could anyone tell me the reason why please?

Thanks in advance

I had obviously replaced the “USERNAME” and “PASSWORD” with the username and password I had set earlier on in the book.

I have found the problem, the author had set the first entity to be “name” instead of “username” for the first place to put values in.

2 Chapters in and I have found two significant typo’s a bit worrying considering its a beginners book…but otherwise a good learning tool
