Many sites feature web forms to collect information from users. Unfortunately, these forms often provide a poor experience for the user, with predictable results. This article will show you how to make filling out web forms more fun (or at least less painful) for your users with the help of PHP and some AJAX magic.
Completing a User-Defined CSS Website with PHP
In the first part, you learned about CSS and some basic tips/techniques for using the slider to display colors. In this part, we will discuss how we are going to write our AJAX and PHP scripts to make our user-defined CSS website.
Create a User-Defined CSS Website with PHP
PHP as a server side scripting language can be used to customize CSS. This can make your website more readable and useful to your visitors. In this article, you'll learn what you can do to let them adjust your site so it looks good to them. This is the first part of a two-part series.
Build A Better Twitter Chat Client Than Chamillionaire
Tuesday evening, August 4th, the musician Chamillionaire launched a live, first showing video on his website along with a Twitter-based chat client. While the Twitter chat client worked from a data perspective, based on what the code showed it looks like most browsers would crash.
Using Division Equations to Make Web Forms Safer with Ajax
From a web developer’s point of view, building a mechanism that permits you to protect online forms against attacks by spam bots, malicious automated submissions, and so forth, can be challenging. Developing such an application often requires using a server-side graphic library to generate the so-called noisy images. However, it’s possible to quickly create a similar mechanism with Ajax, without having to work directly with images generated in the web server. This is the fourth part of a four-part series that explains how to do just that.
Using Integer Multiplication to Protect Web Forms with Ajax
If you’re a web developer who builds Ajax-driven applications and wants to learn how to use this technology for creating more secure web forms, then look no further. Welcome to the third part of a series focused on making web forms safer with Ajax. Made up of four comprehensive tutorials, this series explains how to generate different types of challenge strings via Ajax, which can be incorporated into any existing HTML form with the purpose of protecting it against attacks.
Using Simple Checksums for Web Form Verification with Ajax
As you know, Ajax is a technology that can be used to perform all sorts of clever tasks; this includes building web forms that are less vulnerable to attacks from malicious web bots. Indeed, it’s pretty simple to develop certain mechanisms that permit the dynamic generation of verification codes via Ajax, which must be entered manually by a user before submitting an HTML form. This is the second part of a four-part series that shows you how to make your web forms safer with Ajax.
Protecting Web Forms with AJAX
Are you looking for a new way to protect your web forms from malicious hackers and spam bots? Then you've come to the right place. In this four-part article series, you'll learn how to use Ajax to protect those forms. Keep reading to learn how to build an Ajax-based verification code mechanism that you can use on your own web site.
Using Prototip with AJAX
In the first part of this tutorial we looked at the ease with which a default implementation of Prototip tooltips could be put on the page, and how, with just a little configuration we could change the appearance and behavior of the tooltips. In this part of the tutorial we’re going to take a look at the built-in AJAX functionality boasted by the plugin, and see how we can extend the tooltips by supplying HTML elements instead of plain text as their content.
Using Prototip
Prototype is a popular open source JavaScript framework that is favored by many for its extensive toolset that makes implementing advanced JavaScript functionality a breeze. Prototip is a plugin for Prototype that lets you quickly and easily add fantastic-looking tooltips to your pages with a minimum of code and effort.
Using the google.load() Method with Google`s Ajax Libraries API
Google's Ajax Libraries API is a programming interface that permits web developers to download popular JavaScript packages, such as Prototype, jQuery and Scriptaculous, directly from Google’s servers instead of using local copies of these libraries. In this fourth part of a four-part series on using the API, you'll learn how to serve the jQuery framework without compression.
How to Handle Ajax Errors
An Ajax request behaves like a JavaScript thread. While the request is going on, execution of the JavaScript code in the flow of the code carries on. How do you solve possible conflicts and the resulting errors?
Uncompressing Source Files with Google`s AJAX Libraries API
Welcome to the third part of the series titled “Using Google's Ajax Libraries API.” Made up of four approachable tutorials, this series teaches you how to download and use your favorite JavaScript library by means of this client-side API. It complements the corresponding theory with a large variety of code samples.
Using the jQuery Framework with Google`s Ajax Libraries API
In this second installment of a four-part series, you will learn how to develop an AJAX-driven application that makes use of Google's Ajax Libraries API to work with the jQuery library. Using Google's API means taking advantage of Google's servers, which can be expected to react much more quickly than a single heavily-loaded server. Let's get started.
Using Google`s Ajax Libraries API
Google's new client-side API lets you download some of the most popular JavaScript libraries directly from its servers. If you're interested in dabbling with AJAX, there is no faster way to get your packages and get started. This four-part article series, of which this is the first part, will help get you on your way.
An Enhanced Ajax Approach to Active Client Pages
In this final part of a four-part series, I give you my enhancements to the AJAX approach to Active Client Pages. Before I conclude the series, I will introduce two other approaches to you. Keep reading to learn how to help your web pages load more quickly.
The Ajax Approach to ACP: A Simple Example
This is the third part of my four-part series, Active Client Pages, An Ajax Approach. In this part I illustrate the Ajax approach with a simple example, complete with code. Be sure to read the first two parts; they will help you understand what I'm trying to accomplish here, though the first part of this article does include a quick summary.
Ajax Features Needed to Build Active Client Pages
This is the second part of my four-part series, Active Client Pages – Ajax Approach. In this part of the series, we continue our discussion of the Ajax features we will need to use with ACP, and then we look at the principles of the Ajax approach.
An Ajax Approach to Active Client Pages
If a user were using a slow Internet connection, he would have found that it takes time for him to have his web page displayed (downloaded) at his client computer. Nowadays, only the first page of his web site will take a long time to be downloaded; the rest of the pages will come very fast. Keep reading to learn how we can accomplish this trick. It's all thanks to Active Client Pages and the magic of AJAX.
Beginning Ajax
Ajax is often mistaken for a programming language, when in reality it is more of a standard or technique used to create better, more interactive web applications. It is used to create more responsive web pages by loading certain areas of a page, instead of an entire page. In this tutorial, and the ones that follow, we will learn to work with it to build dynamic web sites.
