PHP Build a Simple PHP Application Integrating with PayPal HTML Forms

Unique identifier for form php?

Finally, we need the form to submit a unique identifier for the order to the process.php file. We need to be able to access that value in an order_id element of the $_POST array, like this: $_POST["order_id"]. For this particular order, the order ID should be 7546. We don’t want this value displayed in the browser. What do we need to add to the form? (Hint: We need to add a new HTML element with three attributes.)

You have to pass an information (order identifier), which is not normally visible - so you should use input element where type attribute has a value of "hidden". This element also need to have other two attributes: name and value. Values of these both attributes are given in task description. Read it carefully.
