This detects screen resolution using javascript and makes it available to php by way of cookies.

Use this to print alternating values from an array.

It cycles through a series of values based on an iteration number.

For example, you could use this for alternating background colors.

A wrapper on top of createElement for getting around IE problems with manipulating the name attribute. Unlike most solutions for this, it tests for which method to use once when the page loads rather than every time an element is created. By Chaos of Lost Souls MUD (a text-based fantasy RPG).

A simple, flexible formula for generating diminishing returns out of input numbers. Full explanation and home, with sample calculators and versions of the code in other languages, on the Lost Souls MUD Grimoire.

Well after searching the internet for something similar to this, I didn't come up with anything...so I made my own! This simple script will track your members' time spent on your website. Please feel free to give comments/suggestions/feedback.

Here's a quick lil' addon for Prototype that I use often.

Prototype.Promise(condition, action, interval)
condition is a string that you want met before an action is run.
action is a function that does the action.
interval is the polling rate for condition in seconds, and defaults to 1

So, for example, you may want function foo to run, but only once bar has been set:

function foo(a,b) {
this.retVal=a+b;
}
var thingy = {
retVal:0
};
Prototype.Promise(
'thingy.retVal=5',
foo.bind(thingy,5,10),
5
);


Then, in some point in the mysterious future, thingy.retVal gets set to 5, at which point, the Promise goes into effect, and thingy.retVal becomes 10.

Where I find this particularly useful is in making sure that a document is loaded before doing something (condition="$$('body').length>=1), as you can see it used for the include functions.

Speaking of which, the following include functions are great for getting scripts and stylesheets into your page. I won't bother with examples, as they're pretty straightforward.

Meanwhile, Prototype.scriptPath will point to wherever in your server's heirarchy Prototype was loaded from. The regex, you'll note allows for names like prototype.compressed.js, prototype.modified.js, 2007-09-28.prototype.js, etc - just in case you want to keep track of your various hacks of Prototype, as I do.

This script performs reliable, cross-browser input autofocus that often can be used simply by dropping it in, with no modifications to the form or HTML body. It refuses to switch focus if it detects that the user has interacted with the form (avoiding a major source of annoyance with autofocus scripts) and correctly handles Firefox tabs opened "in the background", which most autofocus scripts fail on. Official home is on the Lost Souls MUD Grimoire.

This is a cool function that lets you save MySQL query data to an Excel spreadsheet. This is good for taking a backup or if you want to change a lot of information fast, then re-upload it.

I will use the config.php and class.mysql.php files from MySQL DB Class with Extras, so please look at those also.

This is a little function that you can use to print out results of a query. It will dynamicly generate the table for you (like phpMyAdmin). This is a nice little checker that is fast. It beats logging into phpMyAdmin and typing in your query there.

I will use the config.php and class.mysql.php files from MySQL DB Class with Extras, so please look at those also.
