Intro

In lesson 104 you will learn how to work with multiple related checkboxes in classic ASP by storing their values in arrays, use the request object to gather data from the browser and server, understand and use cookies to store information on the visitor's computer, and manage server-side data with session and application variables.

Transcript

Welcome to ASP 104, brought to you by ASPLearningZone.com. I am your instructor, Richard Rost.

In today's class, we are going to cover multiple related checkboxes. In ASP 103, I showed you how to read the value from just one checkbox. What if you have a bunch of them and they all have related information? You can store all that information in an array and pass that one field.

Next, we are going to study the request object. There are all kinds of extra variables and values that you can get from the browser and from the server, and we will take a look at more about the request object.

We are going to spend some time learning about cookies, what they are, what they do, and how you can use cookies to store information on the visitor's computer in a cookie file.

Then, we will learn about how to read and write session variables and application variables. Both of those things have to do with storing information on the server and the server's memory. Session variables store information about the browser and the user. Application variables store information about the website as a whole and use it to pass information between users.

Prerequisites before taking this class: I strongly recommend you take ASP 101 through 103. I will be using standard ASP 3.0 in this class.

Along with Front Page 2003, you can use any web page editor that you like.

If you have any questions, please post them in the Student Forms for this class. You should find the Student Forms next to the video window if you are watching this class online. If not, go to the website and follow the link for the Student Forms for ASP 104.

Summary

Today's video from ASP Learning Zone focuses on working with multiple related checkboxes in ASP. In the previous class, ASP 103, I discussed how to read the value from a single checkbox. Now, imagine you have several related checkboxes that you want to manage together. The solution is to store all of that information in an array and then pass it using just one field, which makes data handling much more efficient.

In addition, this lesson covers the request object in detail. The request object allows you to access a wide range of variables and values sent from both the browser and the server. We will take a closer look at what additional information you can retrieve using this object and how it can be useful in your projects.

We will also spend time discussing cookies. I will explain what cookies are, how they work, and how you can utilize cookies to store data on a visitor's computer by writing to a file known as a cookie file. This is an important concept for managing user data across multiple visits.

Furthermore, today's class introduces session variables and application variables. Both play key roles in storing data on the server, but they serve different purposes. Session variables are used to store information specific to a user and are maintained for the duration of their visit. Application variables, on the other hand, are used to share information across the entire website and between different users, which is ideal for maintaining global states.

Before starting this class, it is important that you have completed ASP 101 through 103, as I will be building on those lessons. We will be using standard ASP 3.0 throughout this course. While I mention using Front Page 2003, you are free to use any web page editor you are comfortable with.

If you have any questions during the course, please use the Student Forms associated with this class. These are available next to the video window if you are viewing the lesson online, or you can visit the website and find the link for the Student Forms for ASP 104.
