PHP Challenge 1: Idiot Box Survey [ edit ] A very old TV Scenario : You are working as IT Support for a small high school in your area. The Parents and Community committee has commissioned a small project to help kids in the school work out exactly how much time they're spending in front of the TV, Computer or Video Game Consoles, as well as collect data on how free time is spent. Creating the form [ edit ] You've been asked to whip up a prototype form to collect the following info (remember your target audience when labeling your fields!)
I am currently doing webpage work for a small management learning institute. I already have the PHP written to interact with my SQL database. Meaning that I can insert the given data into a database. However, when you come to register it will not be automatic. We will receive the contact information (name, address, phone, email, etc... as well as educational background, work experience, how you heard about us, etc...).
by Gina Trapani Last updated: September 2006 A web server is software that continuously runs on a computer and allows other computers to download documents from it. This text that you're reading right travelled over a network connection from Lifehacker's hosting web server to your browser. Web servers are usually loud, scary, headless machines in cold windowless rooms, but you can run one under your desk at home. Why would you want to run a home web server?
The Common Gateway Interface, or CGI, is a set of standards that define how information is exchanged between the web server and a custom script. The CGI specs are currently maintained by the NCSA and NCSA defines CGI is as follows: The Common Gateway Interface, or CGI, is a standard for external gateway programs to interface with information servers such as HTTP servers. The current version is CGI/1.1 and CGI/1.2 is under progress. Web Browsing To understand the concept of CGI, lets see what happens when we click a hyper link to browse a particular web page or URL.
My Poll aims to provide an easy to use add in solution for adding voting interaction on webpages. The package includes both a CGI script and an SSI for embedding into .shtml pages. Both interfaces use the same config file and can be used exclusively or in combination. A question and list of answers is entered in the config file. The included CGI script can be a accessed directly to present the user with the question and list of options.
In case you are interested in how CGI scripts can be written, or if you want to compare your attempt at the exercises with mine, here are the Perl files used to generate them. Environment example : Generates an HTML document listing the values of (most of) the current environment variables. The endless document : Displays one of the many(!) pages of a document with infinitely many pages.
Usually the information supplied by the QUERY_STRING variable should come from the user pressing buttons and entering text in the HTML document. It is this information we would like to package up and send to the CGI script. Each group of buttons and text boxes is called a form , and forms are enclosed between the HTML tags <form> ... </form>. You also have to tell it the URL to send the information to, and how the information is sent. The result is something like this:
What is Perl/CGI? Perl is a simple programming language. It doesn't have to be used on the web, it can run locally on your computer, but it's popular for use on the web. When it's used on the web the programs are called Perl CGI, because CGI is the way that Perl talks to your web browser.
