Code Samples

Cheat sheet with basic code snippets so that I can easily copy/paste them quickly. Feel free to use them too if you find it helpful.

I code on the LAMP stack, so you'll mostly find PHP, JavaScript, HTML, and CSS code samples on my site. I'll add to this page as I encounter more bits of code I use a lot that I want to put on here for easy access.

Or, maybe you're here because you just need pro help with some code...

(Yes, I actually pick up the phone.)

var a = $var;

function fieldClassValidate(){
if( $('.fieldClass').is(':checked') ){
//do something

function functionName($var){

var id = $var;
var dataString = "id=" + id;

type: "POST",
url: "pageName.php",
data: dataString,

beforeSend: function(){
var answer = confirm("Are you sure?");
if (answer){
return true;
} else {
return false;
success: function(){
alert("Processed " + id);


document.getElementById("submit").disabled = true;
var a = document.getElementById("fieldID").value;

$('.className').on('change', function(){
$(this).val($(this).val().replace(/\s+/g, ''));

$('elementID').addClass( "className" );
