HTML_AJAX WordPress Plugin Tutorial

I found a handy tutorial of building a stock lookup plugin for WordPress using HTML_AJAX. Shows how easy HTML_AJAX makes AJAX.

The only problem I see is the code won’t work in PHP5 since introspection will return the method name as GetQuote instead of getquote.

You can fix this by adding the following to the HTML_AJAX_Server instance.

// Create the HTML_AJAX Server
$objServer = new HTML_AJAX_Server();

// Set php4 case compatability so this code will work in 4 or 5
$objServer->ajax->php4CompatCase = true;

The other option too fix this is too set all the methods you want to register which is my prefered fix since it lets you have nice case in your JavaScript functions in php4

    // Create the HTML_AJAX Server
    $objServer = new HTML_AJAX_Server();

    // Create an instance of our stock quote class
    $objStockLookup = new StockQuote();

    // Register the stock quote object with the HTML_AJAX server

If you did this you’ll also have to update the JavaScript to use the cased version of the functions.

  3. What I want to do on my blog, is every few hours take the oldest post and move it to the
    front of the queue, all automatically. Anyone know if there is a plugin that can do this or
    a simple way to set up another plugin to do this (use my own feed perhaps)?
