i need a simple php code storing dropdown list and radiobutton data into my mysql database.
So you haven't written it yet is what you're saying. Ok then.
Well, the basics are pretty simple. Each item in your form should have a name:
[HTML]
<input name="flavor" ...
[/HTML]
When the User submits the form, PHP puts the value of that input into $_REQUEST (also $_GET, $_POST or one of a couple others, depending on the action of your form). So to access that value, you would type something like this:
[PHP]
echo $_REQUEST['flavor'];
[/PHP]
To save it to the database, you'd need to build a query and send it:
[PHP]
$query = "INSERT INTO `tableName` (`col1`, `col2`) VALUES('" . addslashes($_REQUEST['flavor']) . "', '" . addslashes($_REQUEST['caliber']) . "')";
[/PHP]
And so forth. Note that it is good practice to (at the very least) use addslashes to prevent SQL injection attacks.
