insert form data into database php

Insert Data From a Form Into a Database
Now we will create an HTML form that can be used to add new records to the "data" table.
Here is the HTML form:

<html>
<body>
<form action="in.php" method="post">
Firstname:<input type="text" name="firstname" />
Lastname: <input type="text" name="lastname" />
Age: <input type="text" name="age" />
<input type="submit" />
</form>
</body>
</html>

When a user clicks the submit button in the HTML form in the example above, the form data is sent to "in.php". The "in.php" file connects to a database, and retrieves the values from the form with the PHP $_POST variables. Then, the mysql_query() function executes the INSERT INTO statement, and a new record will be added to the database table.

Below is the code in the "in.php" page:

<?php
$con = mysql_connect("localhost","root","");
if (!$con)
{
die('Could not connect: ' . mysql_error());
}
mysql_select_db("my_db", $con);
$sql="INSERT INTO person (FirstName, LastName, Age)
VALUES
('$_POST[firstname]','$_POST[lastname]','$_POST[age]')";
if (!mysql_query($sql,$con))
{
die('Error: ' . mysql_error());
}
echo "one record added";
mysql_close($con)
?>
