Send the request off to a PHP file (gethint.php) on the server Notice that q parameter is added to the url (gethint.php?q="+str) And the str variable holds the content of the input field The PHP File - "gethint.php" Then, I just have to include ajax.inc.php in my Ajax handlers. In cakephp we can use something like $this->autorender = false in order to pass some json string or xml string.
How to perform a reduced knapsack problem. Can you specify which framework you are using? When is a closeable question also a “very low quality” question? what does 256 bytes of internal memory (RAM) on a microprocessor mean?
So your literal response to the request would be "9" (if that was the primary key generated). When the server sends a response in JSON format, server has to tell the browser that the response is in JSON format. It really depends on what framework you are working with how you do this, but normally what I do is instead of rendering a full blow view I just echo out the small bit of content I need. You can use throw statement whenever you need to stop the process and send an error message to the browser. Will brand matter between a rear derailleur and front derailleur? Let’s quickly go through the usual AJAX flow: First, the user opens a web page as usual with a synchronous request. So, I am going to finish my handler.php. But, try-catch model is the best and the most efficient approach according to my personal experience. What you do is check for the AJAX header and serve different content based on that. You can throw a Exception in runtime with a message and an error code. Why do you exit the script just after finding an error on processing? I am working on my own MVC framework in PHP right now. I understand this, but where should I be building my pages template-header-footer, etc...?
