Tedd's Examples
The following are links to examples created for this class and will be discussed in class.
The examples shown here are to show you how PHP code works. Your assignments for each of these topics will be to create example(s) that demonstrate your understanding the concepts.
In all your examples, please remove my name (or 'you' or 'yours') and replace it with your name. In addition, make certain your code works like mine and has links back to your examples page. The purpose of this 'cut/paste' is to allow you to see the code run. You should examine the code to see how it works and is used.
When the assignment asks you for a creative example using the topic of the week, it is up to you to read and review those examples to see how they work and to create an example that also demonstrates how the topic works. For example, if the topic of the week is strings, then a creative example might be to review the PHP manual describing string functions and then use one or more, to alter a string. You may also want to review the Various String Functions link on the right-side of this page.

Week 3. HTML Forms
Chapter 9
- $_GET Form • Do this
- $_POST Form • Do this
- Simple "Sticky" Form • Do this
- All In One Form • Do this
- Simple Dropdown Form
- $_REQUEST Example
- Form - NOT Secure
- Form - Secure
- Redirect
The above shows how to set up a form to gather information from a user via GET and POST super globals. The REQUEST example shows you why you should NOT to use this super global to gather any data I'll explain im class).
The "Simple Sticky Form" demonstrates how to pass the values a user provides to re-populate the form. Note: This example passes the values via the POST super global. It works for the GET super global in same fashion.
The "All in One Form" shows many of the HTML controls that you may use to get a user's input to a set of values. For example, instead of asking for a "true" or "false" from a user, you can have them click a checkbox. Also, instead of asking a use to pick "one of something", you can ask via a set of radio buttons. These controls show you how to gather users input.
The Simple Dropdown Form shows how to use one of the controls shown in the "All in One Form", namely the Dropdown menu.
The Forms - "Form - NOT Secure" and "Form - Secure" are examples that show how JavaScript code can be blocked. You do not want a bad actor to use your form to launch a JavaScript routine (like a mass emailing of spam).
The "Redirect Form" shows how a simple radio button can redirect a Browser to another Website or code.
Your assignment is to demonstrate your command of PHP to provide these controls to the user and how to gather information from the user.

Week 9. Preserve State
Chapter 10
- Query String via GET • Do this
- Query String via POST • Do this

The above examples show how to pass variables between pages.
As you know, from previous assignments, you can pass variables between pages using GET and POST.
You can also store values on a web page using COOKIES.
Please demonstrate an example of you using COOKIES.
Often the number of variables make using GET, POST, and COOKIES make the process too complicated to pass a significant number and organization of those values impractical. As such, you have the option of using SESSIONS. The SESSION examples show how to set up a SESSION and how to use it to pass variables between pages.
• Do thisYour assignment is to demonstrate your command of using SESSIONS. Show your example in a clear and consistent manner to demonstrate how you populate varables using SESSIONS.
