In-Depth Information
The implementation is contained in a single PHP file, called
Product.php . Portions of this file are discussed next.
Filling the Input Values Using Javascript
The first section of the source code of Product.php produces a form
that presents the three attributes to be filled by the user. The first two
attributes, education and marital-status , are discrete and a drop-down
list supplies the possible values; the third attribute is a continuous
attribute called capital-gains . The code below produces this form such
that when the user clicks on the Score button, these values are for-
warded and the PHP code is run.
