How to do Javascript for the HTML/PHP Array (See Below)

Hi Fellas! Here's the clipping of an article about putting HTML variables into a PHP Array upon submission. Right now, I'm having trouble getting Javascript to do the error checking of each of the HTML variable if it's variable name is treated as an array. Anyone know of a workaround to it where Javascript can detect and work with the HTML Array-like variable name??? --snip-- 3. How do I create arrays in a HTML <form>? To get your <form> result sent as an array to your PHP script you name the <input>, <select> or <textarea> elements like this: <input name="MyArray[]"> <input name="MyArray[]"> <input name="MyArray[]"> <input name="MyArray[]"> Notice the square brackets after the variable name, that's what makes it an array. You can group the elements into different arrays by assigning the same name to different elements: <input name="MyArray[]"> <input name="MyArray[]"> <input name="MyOtherArray[]"> <input name="MyOtherArray[]"> This produces two arrays, MyArray and MyOtherArray, that gets sent to the PHP script. It's also possible to assign specific keys to your arrays: <input name="AnotherArray[]"> <input name="AnotherArray[]"> <input name="AnotherArray[email]"> <input name="AnotherArray[phone]"> The AnotherArray array will now contain the keys 0, 1, email and phone. Note: Specifying an arrays key is optional in HTML. If you do not specify the keys, the array gets filled in the order the elements appear in the form. Our first example will contain keys 0, 1, 2 and 3. See also Array Functions and Variables from outside PHP. --snip--
