Yup. So for example you have a form in home.htm
<form action="send.php" name="form" method="post">
<input type="text" name="myaddress" value="" />
<input type="submit" name="submit" value="Submit" />
</form>
When you press submit the form will go to send.php
Then on send.php you first need to declare the variables to be passed into database...
$myaddress = $_POST['myaddress'];
You use the name of the var to pass.
Then you insert into database...
// connect to database
include (db_connect.php);
// perform query
$query="INSERT INTO table values('$myaddress')";
$result = mysql_query($query) or die(mysql_error());
Hope that helps.
