MooTools – Free Syntax Highlighting Class

May 5, 2009 3 Comments

Lighter.js is a free syntax highlighting class developed with MooTools. It was created with the MooTools developer in mind and takes advantage of many of the Framework’s features. Using it can be as simple as adding a single script to your web page, selecting the elements you wish to highlight, and Lighter.js takes care of the rest.

All browsers supported by MooTools are compatible with Lighter.js. It’s possible that it may work with earlier/other browsers but these are unofficially supported. The official list is:

Safari 2+
Internet Explorer 6+
Firefox 2+
Opera 9+

WordPress – List the most recent comments

May 3, 2009 5 Comments

Easily list the most recent comments in a sidebar or a tab. The code below will list the 10 most recent comments. You can change the number displayed by changing the value of the variable, $intCommentLimit to list more or less comments

<?php
function getRecentPosts() {
    global $wpdb;
    $intCommentLimit = 10;
 
    $strSql = "SELECT DISTINCT ID,
                      post_title,
                      post_password,
                      comment_ID,
                      comment_post_ID,
                      comment_author,

PHP – Generate a random password based on length

September 15, 2008 No Comments

Here’s a quick function to generate a password. All you have to do is call it passing the length of your required password as an argument.

<?php
function generatePassword($intNumOfChars) {  
    if (is_numeric($intNumOfChars) && ($intNumOfChars > 0)) {
    $strChars = "0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ_";
 
    for ($i = 0; $i < $intNumOfChars; $i ++)  {
        $strPassword .= $strChars[rand(0, strlen($strChars)-1)];
     }
    }
    return $strPassword;
}
?>

<?php

function generatePassword($intNumOfChars) {

if (is_numeric($intNumOfChars) && ($intNumOfChars > 0)) {

$strChars = "0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ_";

for ($i = 0; $i < $intNumOfChars; $i ++) {

$strPassword .= $strChars[rand(0, strlen($strChars)-1)];

}

return $strPassword;

PHP – Truncate a string to a given length

September 9, 2008 No Comments

This is a function I use to display the ellipses when I want to truncate and display a summary of a larger body of text.

<?php
function truncateString($intLength = 0, $strText = "") {
    if ($intLength == 0) {
        return $strText;
    }
     
    if (strlen($strText) > $intLength) {
        preg_match("/[a-zA-Z0-9]{0, " . $intLength . "}/", $strText, $strNewText);
        return ($strNewText . "...");
    }
    else {
        return $strText;
    }
}
?>

<?php

function truncateString($intLength = 0, $strText = "") {

if ($intLength == 0) {

return $strText;

}

if (strlen($strText) > $intLength) {

preg_match("/[a-zA-Z0-9]{0, " . $intLength . "}/", $strText, $strNewText);

return ($strNewText . "...");

}

else {

return $strText;

Get the filename from upload form using Javascript

August 8, 2008 11 Comments

I needed a way to access the filename of a file being uploaded or attached using the input file from a form. So, I created a nice little function to achieve this. Hopefully it comes in handy for someone.

<script>
function getNameFromPath(strFilepath) {
    var objRE = new RegExp(/([^\/\\]+)$/);
    var strName = objRE.exec(strFilepath);
 
    if (strName == null) {
        return null;
    }
    else {
        return strName[0];
    }
}
</script>

function getNameFromPath(strFilepath) {

var objRE = new RegExp(/([^\/\\]+)$/);

var strName = objRE.exec(strFilepath);

if (strName == null) {

return null;

}

else {

return strName[0];

}

</script>

Javascript – Capitalize Each Word in a String

July 26, 2008 3 Comments

This is a great little function that I whipped up and use to capitalize every word in a string. I can’t tell you how many times I’ve had to use this. Hope you find it useful as I have!

<script>
function wordToUpper(strSentence) {
    return strSentence.toLowerCase().replace(/\b[a-z]/g, convertToUpper);
 
    function convertToUpper() {
        return arguments[0].toUpperCase();
    }
}
</script>

function wordToUpper(strSentence) {

return strSentence.toLowerCase().replace(/\b[a-z]/g, convertToUpper);

function convertToUpper() {

return arguments[0].toUpperCase();

}

</script>

Datejs – An Open-Source JavaScript Date Library

July 21, 2008 2 Comments

Datejs is an open-source JavaScript Date Library. Comprehensive, yet simple, stealthy and fast. Datejs has passed all trials and is ready to strike. Datejs doesn’t just parse strings, it slices them cleanly in two.

<script>
// What date is next thrusday?
Date.today().next().thursday();
  
// Add 3 days to Today
Date.today().add(3).days();
  
// Is today Friday?
Date.today().is().friday();
  
// Number fun
(3).days().ago();
 
// 6 months from now
var n = 6;
n.months().fromNow();
  
// Set to 8:30 AM on the 15th day of the month
Date.today().set({ day: 15, hour: 8, minute: 30 });
  
// Convert text into Date
Date.parse('today');
Date.parse('t + 5 d'); // today + 5 days
Date.parse('next thursday');
Date.parse('February 20th 1973');
Date.parse('Thu, 1 July 2004 22:30:00');
</script>

// What date is next thrusday?

Date.today().next().thursday();

// Add 3 days to Today

Date.today().add(3).days();

// Is today Friday?

Date.today().is().friday();

// Number fun

(3).days().ago();

// 6 months from now

var n = 6;

n.months().fromNow();

// Set to 8:30 AM on the 15th day of the month

Date.today().set({ day: 15, hour: 8, minute: 30 });

// Convert text into Date

Date.parse('today');

Date.parse('t + 5 d'); // today + 5 days

Date.parse('next thursday');

Date.parse('February 20th 1973');

Date.parse('Thu, 1 July 2004 22:30:00');
