User Interaction and Email Automation in Symfony 1.3: Part1

by Tim Bowler | September 2009 | MySQL Open Source PHP Web Development

After developing an application in Symfony 1.3, the next aspect we will cover is creation of forms. Symfony incorporates a subframework that handles forms, which once mastered, makes creating forms an enjoyable task. In this two-part article by Tim Bowler, we are going to see how easy it is to create and validate forms by creating a newsletter signup module for our web site. We will then convert our new module into a plugin so that we can use it with other projects.

By the end of this article you will know how to:

  • Add a third-party library to send automated emails
  • Create and modify Propel-based forms
  • Use flash variables
  • Create a plugin and package it up for redistribution

User Input Validation in Tapestry 5

by Alexander Kolesnikov | January 2009 | Content Management Java Open Source

One of the benefits of having a web application is that it can be very easily accessed by everyone around the world. One of the downsides of this is that when so many people use your application, they are going to have errors in their input. Some people are not attentive, others are tired and, finally, everyone in this world has his or her individual style of thinking, so something that seems obvious to the developers of the application might puzzle someone else.

A well-designed web application should immediately be able to define that the input is wrong and stop—otherwise all kinds of errors can happen inside of the application. If this application is user-friendly, it should:

  • Clearly and unambiguously inform the user that some part of the input is erroneous, and should be corrected.
  • Identify the field that is erroneous and mark it in some way.
  • If possible, display the erroneous value, and maybe even explain why exactly it is wrong.

In this article by Alexander Kolesnikov, we will see how Tapestry 5, being a highly efficient and user-friendly framework, handles these issues. For the purpose of this article we will use a Tapestry web application named Celebrity Collector.

User Extensions and Add-ons in Selenium 1.0 Testing Tools

by David Burns | November 2010 | Beginner's Guides RAW Open Source

In this article, by David Burns, author of Selenium 1.0 Testing Tools, we are going to look at how we can expand Selenium. This is for those times when Selenium's API is not verbose enough.

Selenium has the ability to allow developers to create functions, in the same three-column format, to all tests to reuse snippets of code instead of evaluating them with getEval calls.

User extensions and add-ons are all written in JavaScript. This is due to Selenium's core being written in JavaScript. Let's now have a look at user extensions.

In this article, we shall discuss:

  • User extensions
  • Add-ons

So let's get on with it...

User Authentication with Codeigniter 1.7 using Twitter oAuth

by Adam Griffiths | May 2010 | Open Source PHP Web Development

User authentication is an important part of many applications. Let's look at how we would utilize third-party authentication methods. oAuth is an open protocol for secure user authentication across APIs. It allows users to gain limited access to websites by using their Twitter credentials. It's a very sound method of user authentication, and doesn't take too much work to get going. Twitter oAuth is used by hundreds of third-party Twitter clients and mashups—just to give you an idea of how useful it can be.

In this article by Adam Griffiths, author of CodeIgniter 1.7 Professional Development, we will:

  • Learn how Twitter oAuth works
  • Create a library for authentication
  • Utilize the library in order to create an application to demonstrate how it works

User Authentication with Codeigniter 1.7 using Facebook Connect

by Adam Griffiths | May 2010 | Open Source PHP Web Development

In a previous article we covered User Authentication with Codeigniter 1.7 using Twitter oAuth. In this article by Adam Griffiths, author of CodeIgniter 1.7 Professional Development, we will continue our discussion on how we can utilize third-party authentication methods by using Facebook Connect.

Facebook Connect is just like Twitter oAuth, but for Facebook accounts. It doesn't use the oAuth protocol, so its workings might seem slightly different to developers. To users, however, the difference is marginal. Just like in Twitter oAuth, users do not need to enter any of their account credentials on your website or application—it is all handled by Facebook.

User Access Control in Drupal 6

by David Mercer | April 2008 | Content Management Drupal Open Source

In this article by David Mercer, we will look at an entirely different aspect of running a Drupal website. Once we have added the functionality to the site, we now have to give some thoughts about how this functionality is to be accessed, or by whom. As the site grows, you will most likely feel the need to delegate certain responsibilities to various people. Alternatively, you might organize a team of people to work on specific aspects of the site. Whatever is required, at some stage you will have to make decisions about who can do what, and Drupal makes sure that it is possible to do precisely this.

Having Drupal simplify the implementation of your access control policies does not mean that the task is a trivial one. There is still much thought that needs to go on behind the scenes in order to create a sophisticated, and above all, effective policy for controlling access to the site. Because of this, we will spend a bit of time exploring the ramifications of the various choices available, instead of simply listing them. Taking a holistic approach to implementing an access control policy will ensure you don't end up with any nasty surprises down the line.

Specifically, this article will look at Planning an access policy, Roles, Users, and Access rules.

Useful Maven Plugins: Part 1

by Brett Porter Maria Odea Ching | September 2009 | Java Open Source

In this article by Brett Porter and Maria Odea Ching, we will take a closer look at some of the plugins from two locations: those hosted as part of the Apache Maven project (http://maven.apache.org/plugins/), and a number of plugins from the Codehaus Mojo project (http://mojo.codehaus.org/plugins.html), which is oriented directly towards Maven plugin development.

Where possible, we will apply the plugins to our example application to see how they can be used in practice, and then cover some of the other use cases and best practices for their use.

Use of Templates in Report using BIRT

by John Ward | July 2010 | Open Source

BIRT is an open source business intelligence and reporting tool, built on top of the Eclipse Framework. BIRT is used by developers for building reports that can best represent data and tell a story of that data that is easy to follow. In addition, BIRT can be integrated into a product, to allow that product to provide reporting capabilities.

In this article by John Ward,author of BIRT 2.6 Data Analysis and Reporting we will look at templates. Templates are existing report layouts that can be used as a starting point for new reports. This is useful if we use a similar layout in all our reports; we can then create a template and build from that for each new report.

Use of Stylesheets for Report Designing using BIRT

by John Ward | July 2010 | Java Open Source

BIRT is an open source business intelligence and reporting tool built on top of the Eclipse Framework. BIRT is used by developers for building reports that can best represent data and tell a story of that data that is easy to follow. In addition, BIRT can be integrated into a product to allow that product to provide reporting capabilities. 

In this article by John Ward,author of BIRT 2.6 Data Analysis and Reporting we will look at how BIRT uses stylesheets in report designs and how styles can be grouped in a library to create themes. This will allow us to have certain sets of styles ready for use any time we develop a report so that we, as a report developer, can focus strictly on the technical aspects of the report while maintaining a consistent visual presentation.
