Mysidia Adoptables Support Forum - Insert Data/Tables Trouble

So somedays I'm a total noob with coding. I need to have someone enter info into a form, have the info put into a database, and then I'll pull it and display it.

I have the form done (I think) and the pulling part I /think/ I'm good with. I'm having trouble getting the info into the table though. Mostly because I don't know how to set up a table.

Code:

<?php

$con = mysql_connect("localhost","gloometh_me","**********"); //Replace with your actual MySQL DB Username and Password

if (!$con)

{

die('Could not connect: ' . mysql_error());

}

mysql_select_db("gloometh_adopts", $con);

$code=mysql_real_escape_string($_POST['code']);

$sql="INSERT INTO clicks (code) VALUES ('$code')";

if (!mysql_query($sql,$con)) {

die('Error: ' . mysql_error());

}

echo "The form data was successfully added to your database.";

mysql_close($con);

?>

This is my submitting page - I think its alright. I just need some help setting up a table to hold the data. Help please?
