A new week is coming and in this post I want to suggest you some interesting tutorials and resources for web developers I bookmarked this week. If you want to suggest a link, please leave a comment.

1. InfoVis Toolkit
The JavaScript InfoVis Toolkit provides tools for creating Interactive Data Visualizations for the Web. It supports multiple data representations: treemaps, radial layouts, hypertrees/graphs, spacetree-like layouts, and more.

2. Vaadin
Vaadin is a Java framework for building modern web applications that look great, perform well and make your user happy.

3. Flip!
Flip is a jQuery plugin for jquery that will flip HTML elements in four directions. It’s really simple to implement and customize.

4. Uploadify
Uploadify is a jQuery plugin that allows the easy integration of a multiple (or single) file uploads on your website. It requires Flash and any backend development language. An array of options allow for full customization for advanced users, but basic implementation is so easy that even coding novices can do it.

5. Create a Twitter-Like “Load More” Widget
Both Twitter and the Apple App Store use a brilliant technique for loading more information; you click the link and fresh items magically appear on the screen. This tutorial teaches you to use AJAX, CSS, Javascript, JSON, PHP, and HTML to create that magic. This tutorial will also feature both jQuery and MooTools versions of the script.

6. FullCalendar
FullCalendar is a jQuery plugin that provides a full-sized, drag & drop calendar like the one below. It uses AJAX to fetch events on-the-fly for each month and is easily configured to use your own feed format (an extension is provided for Google Calendar). It is visually customizable and exposes hooks for user-triggered events (like clicking or dragging an event).

10. Creating a Keyboard with CSS and jQuery
Sometimes it’s just fun to play around with the programming languages we know and see what we can create. It might be nice to create a little online keyboard with CSS, and then make it work with jQuery. The keyboard includes “action” keys (caps lock, shift, and delete) which dynamically changes the keyboard when clicked. This tutorial it’ll show you how to build it.

11. Img Notes
Img Notes is an useful jQuery plug-in to add notes over images in a Flickr-like style. It’s simple to implement and customize.

13. Simple vibration effect for your form box with jQuery
This effect can be used to validate certain criteria in your form. Other than using highlighter to highlight the error area, we can use a more creativity approach by vibrating that particular input box to alert the user. This tutorial demonstrate a very easy way to understanding how vibration works on the web and how it can be used in your web design.

14. epiClock
epiClock is an extremely lightweight jQuery plugin which gives users the ability to easily create and manage any number of javascript powered clocks.

Welcome to Woork’s Follow Friday List, Issue 01 (23 July 2009). Every week I propose a new list with 10 interesting Twitter users you have to follow! Any suggestion for the next #FollowFriday list? Please Follow me on Twitter!

In this post I want to suggest you 10 useful code snippets for web developers based on some frequetly asked questions I received in the past months for my readers. This collection include several CSS, PHP, HTML, Ajax and jQuery snippets. Take a look!

1. CSS Print Framework
Hartija is an universal Cascading Style Sheets Framework for web printing. To use this framework download the CSS file here and use this line of code into your web pages:

2. CSS @font-face
This snippet allows authors to specify online custom fonts to display text on their webpages without using images:

@font-face {
font-family: MyFontFamily;
src: url(‘http://’);
}

3. HTML 5 CSS Reset
Richard Clark made a few adjustments to the original CSS reset released from Eric Meyers.

4. Unit PNG Fix
This snippet fixes the png 24 bit transparency with Internet Explorer 6.

5. Tab Bar with rounded corners
This code illustrates how to implement a simple tab bar with rounded corners:

6. PHP: Use isset() instead of strlen()
This snippet uses isset() instead strlen() to verify a PHP variable (in this example $username) is set and is at least six characters long. (via Smashing Magazine).

7. PHP: Convert strings into clickable url
This snippet is very useful to convert a string in a clickable link. I used this snippet for several tutorials; for example take a look at this link Simple PHP Twitter Search ready to use in your web projects where I used this snippet to convet into a clickable link all textual links contained in a tweet.

<? php
function convertToURL($text) {
$text = preg_replace("/([a-zA-Z]+:\/\/[a-z0-9\_\.\-]+"."[a-z]{2,6}[a-zA-Z0-9\/\*\-\_\?\&\%\=\,\+\.]+)/"," $1“, $text);
$text = preg_replace(“/[^a-z]+[^:\/\/](www\.”.”[^\.]+[\w][\.|\/][a-zA-Z0-9\/\*\-\_\?\&\%\=\,\+\.]+)/”,” $1“, $text);
$text = preg_replace(“/([\s|\,\>])([a-zA-Z][a-zA-Z0-9\_\.\-]*[a-z” . “A-Z]*\@[a-zA-Z][a-zA-Z0-9\_\.\-]*[a-zA-Z]{2,6})” . “([A-Za-z0-9\!\?\@\#\$\%\^\&\*\(\)\_\-\=\+]*)” . “([\s|\.|\,\<])/i", "$1$2$4″,
$text);
return $text;
}
?>

8. jQuery: Ajax call
This is the most simple way to implement an Ajax call using jQuery. Change formId and inputFieldId with the ID of the form and input field you have to submit:

$(document).ready(function(){
$(“form#formId”).submit(function() {
inputField = $(‘#inputFieldId’).attr(‘value’);
$.ajax({
type: “POST”,
url: “yourpage.php”,
cache: false,
data: “inputField =”+ inputField,
success: function(html){
$(“#ajax-results”).html(html);
}
});
return false;
});
});

9. CSS Layouts Collections
This page contains a collection of over 300 grids and CSS layout ready to use in your projects. Take a look, it’s very useful.

10. Simple versatile multilevel navigation Menu
Several months ago I found this simple code (HTML + CSS + JavaScript for jQuery) to implement a versatile multilevel navigation menu (please send me the original source if you find it!). I think it’s the simpler and faster way to do that. The result is something like this:

The only thing you have to do is to create nested &ltul> lists into a main list with id=”nav”, in this way:

  • Link 1
  • Link 2
  • Link 3
    • Link 3.1
    • Link 3.2

      …and use this basic CSS code (you have to modify it to customize the layout of this menu with the style of your site!):

      #nav, #nav ul{
      margin:0;
      padding:0;
      list-style-type:none;
      list-style-position:outside;
      position:relative;
      line-height:26px;
      }
      #nav a:link,
      #nav a:active,
      #nav a:visited{
      display:block;
      color:#FFF;
      text-decoration:none;
      background:#444;
      height:26px;
      line-height:26px;
      padding:0 6px;
      margin-right:1px;
      }
      #nav a:hover{
      background:#0066FF;
      color:#FFF;
      }
      #nav li{
      float:left;
      position:relative;
      }
      #nav ul {
      position:absolute;
      width:12em;
      top:26px;
      display:none;
      }
      #nav li ul a{
      width:12em;
      float:left;
      }
      #nav ul ul{
      width:12em;
      top:auto;
      }
      #nav li ul ul {margin:0 0 0 13em;}
      #nav li:hover ul ul,
      #nav li:hover ul ul ul,
      #nav li:hover ul ul ul ul{display:none;}
      #nav li:hover ul,
      #nav li li:hover ul,
      #nav li li li:hover ul,
      #nav li li li li:hover ul{display:block;}

      …and this is the JavaScript code for jQuery you have to copy in the tag of the pages that use this menu:

      function showmenu(){
      $(“#nav li”).hover(function(){
      $(this).find(‘ul:first’).css({visibility:”visible”, display:”none”}).show();
      }, function(){
      $(this).find(‘ul:first’).css({visibility:”hidden”});
      });
      }

      $(document).ready(function(){
      showmenu();
      });

Code highlighters are very useful tools to present code snippets on your blog or website with a professional look and improve the readability of code you provide for your readers. In this post I want to reply to some requests I received in the past weeks about this topic and suggest you my five favourites code highlithers.

1. SyntaxHighlighter
SyntaxHighlighter is a popular code highlighter to help a developer/coder to post code snippets online with ease and have it look pretty. It’s 100% Java Script based and it doesn’t care what you have on your server. This is the final result:

2. Quick Highlighter
Quick Highlighter is an useful online tool to convert a plain text that contains some code (HTML, PHP, JavaScript) to formatted-highlighted code ready to copy and past on your blog or website. This is the result:

3. FV Code Highlighter
Frank Verhoeven released this great code higlither that transforms plain text in higlighted code in the same style of the Dreamweaver higligther. The result is very nice and professional:

4. Source Code Highlighter
This online tool allows you to highlight your C#, VB, ASPX, HTML, XML, JavaScript code for publishing on a web site or in a blog.It doesn’t use CSS styles in output, but pure HTML FONT (size, color and font attributes) tag.

5. Highlight.js
Highlight.js highlights syntax in code examples on blogs, forums and in fact on any web pages. It’s very easy to use because it works automatically: finds blocks of code, detects a language, highlights it.
