Class Exercise: Data Collection Form
                      
The form tag is used to create an HTML form:  <form> input elements </form>
1. Create an HTML page with form "scaffolding".



Input element--textbox for data input by a user: 
    <input type="text" name="dataItemName"/>
2. For this form, define an input item with text box for an item name.



Label for an input element: <label> labelValue </label>
3. Specify an identifying label for an input text box.



Password field: 
   <form>
   Password: <input type="password" name="pwd" />
   </form>
4. Given that a password is to be tested, add an input item with textbox for a
   user's password. That is optional for this exercise: only input items for a
   price and a quantity are needed.



Submit Button: A submit button is used to initiate processing of form data. 
   <input type="submit" value="click me"/> 
5. Include a submit button in your form definition.





6. Add method and action attributes to the form's open tag. Specify the "post"
   method, and for the action reference a php file name "ProcessForm.php".
   
   
   
7. Code a php script to access the $_POST array for the details of the form 
   variables for an item name, price, and quantity. Assign their values 
   to local variables. Compute an amount as the product of price and 
   quantity. Print these data items with identifying labels.
