INSERT & CREATE TABLE doesn't seem to be working - php

Question

I'm currently experiencing some problems.
Basically, I use PDO and I want to create a table and insert some stuff into the table.
I've tried searching for solutions, but it doesn't seem like anything is working.
Please take a look at this:
public function install()
{
global $con;
$sql = "CREATE TABLE if not exists users
(id INT(11) PRIMARY_KEY,
uname VARCHAR(30) ,
pass VARCHAR (40))";
$sq = $con->query($sql);
if ($sq)
{
echo "Table successfully created!";
}
else
{
$this->errors[] = 'Error creating table: users';
}
$sql_code = "INSERT INTO users (
`uname`,
`pass` ) VALUES(
`$this->username`,
`$this->password`
)";
$sq1 = $con->query($sql_code);
if ($sql_code)
{
echo "Successfull!";
}
else
{
echo "Error creating admin user!";
}
}
NOTE: The database connection is set in another file called config.php and I've also included the config.php file to the code.

Well, there could be plenty of things going on, perhaps at the same time.
Maybe your database connection is failing (I'd recommend passing the connection $con by reference to the function install rather than using the global keyword).
Maybe you don't have enough rights to create a table in the database.
Also you are not binding your parameters, this would be the correct way to do it:
$sql_code = "
INSERT INTO users (
uname,
pass
)
VALUES (
:userName,
:password
);
";
$sq1 = $con->prepare($sql_code);
$sq1->bindParam(':userName', $userName);
$sq1->bindParam(':password', $password);
$sq1->query($sql_code);
