Assuming a basic knowledge of PHP, XML, JavaScript and MySQL, this book will help you understand how the heart of AJAX beats and how the constituent technologies work together. After teaching the foundations, the book will walk you through numerous real-world case studies covering tasks you'll be likely to need for your own applications:Server-enabled form-validation pageOnline chat collaboration toolCustomized type-ahead text entry solutionReal-time charting using SVGDatabase-enabled, editable and customizable data gridRSS aggregator applicationA server-managed sortable list with drag&drop support using the script.aculo.us JavaScript toolkitThe appendices guide you through installing your working environment, using powerful tools that enable debugging, improving, and profiling your code, working with XSLT and XPath.From the Author, Cristian Darie AJAX and PHP: Building Responsive Web Applications is mainly a book for beginners, but when designing its contents we tried to find the ideal blend of topics that would help both novice and experienced web developers make a big step forward. One customer was very kind to let us know, through a review, that we succeeded:The theory behind all the technologies used is very clearly explained, without boring you with details about obvious things. Right from the first chapter you start learning by examples. The examples can be easily adapted to many web projects and they cover stuff that is both useful and fun.Here are a few examples of such useful and fun things that you can find in this book:details on using proxy scripts to work (...) więcej around the security measures in modern browsersclient-side and server-side code that doesn't break when fed with special characters (such as code that works efficiently with Internet Explorer 5, 6 and 7, Firefox, Opera, Safari, and othersa very quick introduction to SVG, the new rebel kid of the web (and of the house)client-server communication based on message queues that guarantee that your messages aren't lost on the way, and arrive in the intended order at the destinationserver-side state management techniques that use query string parameters and database records to keep track of your client's activitysimple yet effective error-handling structures that combine JavaScript code and PHP code to report when something bad happens on the client or on the servera live errata page that is updated as soon as anyone reports a suggestion or a correctiona friendly AJAX tutorial and many case studies that teach you how to use JavaScript, PHP, MySQL and XML together in order to achieve wonderful resultsThe book's authors and the publisher are listening to your feedback, and appreciate when you invest some time to let them know what you think. The first result of this collaboration is an updated version of the AJAX Chat case study that uses (and teaches) JSON instead of XML. Find this new chapter in the code download or on my website.Thanks for reading such a long message. Have fun! Cristian Darie. Spis treści:
