|4070||Passing variable between PHP pages - hidden fields, cookies and sessions|
Variables within a program are lost when the program exits ... unless the program takes some sort of action to save them. And if it does, you've then got to have another program pick them up to use them somehow.
Web applications in PHP are a series of short-running programs. A program is run each time ...
|3918||Multiple page web applications - maintaining state - PHP|
As you want to do more in an online application, you need to link a series of forms together. There's a limit to how much you can expect your users to enter on one page, and almost inevitably they'll want feedback as they go through a series of steps. So multiple forms is natural, with each encouraging ...
|3820||PHP sessions - a best practice teaching example|
Whether you're selling airline tickets, updating financial records, or running a forum, you'll need software on your web server that maintains state. In other words, software which remembers who you are from page to page, remembers what you've been doing, and doesn't insist on you logging in each time.
|3540||Easy session example in PHP - keeping each customers data apart|
When you go to a shop, you're not kept waiting outside until the previous customer leaves. The shop will have multiple shopping baskets / trollies, or muliple assistants. And that's the way you want it when you visit a web site too. This means that the web site programmer has to be very careful to ...
|2738||What is all this SESSION stuff about? (PHP)|
If you're booking an airline flight online, you'll be taken through a series of screens to select route, dates, times, passengers, seats, then to enter payment details, and perhaps visa / government information too. It would be impractical to do the whole job on a single page, as you need the intermediate ...
|2416||Automating access to a page obscured behind a holding page|
Question: "I have a web page that I visit which sends me an initial response to say that it's working on the results, and then the results appear a few seconds later. I want to use an automed process / program on my computer to visit this page and store the final results, rather than having to access ...
|1911||Remember Me - PHP|
Here's a paradox for you as a web site designer, when putting together a web site which requires a login.
Most of your users are regulars, who really don't want the hassle of logging in every time they visit ... but at the same time, you can't allow blanket, long term logins as your site is often accessed ...
|1766||Diagrams to show you how - Tomcat, Java, PHP|
I like to work with a flipchart occasionally, and I have been doing so quite a bit this week, which is a week that I'm giving a wide ranging web server deployment course under Linux, covering both LAMP / PHP technologies, and Tomcat / Java too. Why do I like using a flipchart? Because it encourages ...
|1739||Bath, Snake or Nag?|
If you're running a web application through a number of phases , you've a choice of three ways of keeping information from one page to the next (keywords - sessions, shopping carts!).
You can use a bathtub - each time history (data) is entered, it gets added to a collection which gets passed back and ...
