As you may have noticed, I have taken a little break from posting. I am having to refocus some of my extra time, what little there is, on some other projects. However, I will be starting posting again in January of 2011. I will continue the Facebook API integration, CakePHP…
Now that I have jumped almost 2 weeks without a post, as I have been super busy, this should have been a real easy item to post, but I wanted to make sure that this is done correctly. This is probably one of the easiest methods to add some great Facebook functionality in your site. This revolves around comments to a page. In my example, I am posting topics to discuss. This is mainly just a small little blurb that I will enter via an admin form on the site, and then list the different topics for everyone to select one. Once they select it, they can view the details of the topic and then comment on it using the Facebook API/Social plugin. So as always, lets go through a basic plan for this idea.
1. The model is Topic, with a table in the DB labeled “topics”
2. Only the admin has access to add or edit the topics
3. All comments on this topic will be done through the Facebook API/Social Plugin Comments
4. Topics will have a title that will also double as the Unique ID (to be explained later)
5. Topic titles, or themes, will not be allowed to be edited, to be explained why later
6. Administration of the comments will be done by the Facebook Application admins, which differs from the site admins
7. Start Dates will determine if the topic is allowed to be visible yet
8. End dates are optional, and will be built upon later with more advanced FBML/FB JS libraries
And there it is, some basic ideas behind the whole idea. So now lets get into some of the items called out in Numbers 4 and 5

This post is just a quick reminder of common sense that should be on every application. Whether it is a Facebook application, a Twitter application, or just a connected application via webservices, you should never expose sensitive data. I mention this because of my previous post which shows how to…
OK, I finally got my data models set up and working. I have the initial CakePHP set up on the site, it is using v1.3, and now I am ready to set it up for the Facebook integration, and start to add the integration. When we first set up the application on the Facebook side, I chose to do an “iframe” version of the application, as I want Facebook on my site, and be able to have integration with some of the great Facebook tools on the site, and be able to “promote me”. And remember this is just a way to show a possible real world example of how to integrate these things with your site. Actual applications may vary, but this is the base to integrate. At least, as of this posting it is the base, it may change in the future.
So lets go ahead and dive into it. If you do not have the application ID for your Facebook application, you can get it at the following:
http://www.facebook.com/developers/apps.php
The next thing is to grab the API and code from Facebook. This can be found at the following page:
http://developers.facebook.com/docs/
This is the main page, and you will need to scroll to the bottom of the page. This will list different APIs that are available. I am going to be using the PHP and JavaScript SDKs. This will provide the back end that I will want, and will also provide a positive user experience on the front end. So be sure to download both SDKs.
After that, now we need to start getting some stuff set up. In this post, I am just going to explain how to get this set up, and working right now. It is important that we get the correct items working, and so we will be working with the “pages” area for the JS SDK, and creating a very simple controller for the PHP SDK so we can get set up and running. I am just using, for right now, the base CakePHP CSS styles and layouts. All we need is a page to display some of the basic items to ensure that we have installed the SDKs in the proper locations. So lets go.

I am still working forward on the Facebook integration and resume stuff. And will get that posted when I have completed the data model and the basic set up. I will also post about how to integrate Facebook into a CakePHP application. But in the mean time, there was something…
The next few posts will examine how I will integrate a Facebook application into one of my sites: stephenhird.com. If you have browsed to this site, you will see there is already a Facebook platform there. And while it does show some of the great things to do with the API, it is very basic and really does nothing. So In this post I will examine what I want to do with it, how to set up an initial application on Facebook, and then go from there. This will likely happen over the next few weeks/months and will be a little more drawn out depending on how much time I have to document this process. This is step one, and step one will always include planning.
First I need to figure out what I want to have on my site. Since it is my name that is on the URL, I will need to create a way that this site will be an online portfolio, biography and information repository. When doing this for any site, it is important to remember your brand. Even for individual sites like this, it is important for branding, because this is who I am, I do not want it to be a classic case of slop on the web. This site before was mainly just a testing ground and now will need to be more.
A side note here, my name is the same spelling as a famous photographer based in London. His site is well put together with good descriptive links and a great example of combining minimalist ideas with styled presentation. He keeps his brand on the pages and the site does not confuse or mislead with extra peripheral items, or overuse of Flash or other heavy web technologies loading down the page. His site is located at: http://www.stephenhird.co.uk/
OK, now on to the planning and setting up the Facebook Application.

ORM, that magical acronym that can send developers into a flurry of excitement, or the rolling eyes of grief. ORM stands for Object Relational Mapping. Used correctly, this can really help applications convert data into objects ready to use. While it does cause some overhead, the key thing to remember is that used properly, it can be really helpful. But that is also the way it is with anything related to code. Since I focus mainly on the open source areas, examining an ORM tool will be limited to the PHP view and aspect.
When designing the data objects, it is important to understand the data and how it relates to the application and other objects. Usually it is the planning sessions that get overlooked, or hurried, and create a problem for later on. This is why using a tool to help with this is always good. I specifically look for more of an ERD (Entity Relationship Diagram) type of tool that can help me visualize and document the data objects. Never underestimate the power of a visual diagram for data. This is worth everything when coming on a new project, or bringing in new resources to a major project. It can drastically decrease the learning curve. There are different tools out there that can help with ERD and ORM design, with the basic Visio diagrams (a Microsoft product), to more robust ERD tools that include different UML (Unified Modeling Language) tools integrated with it like MagicDraw. Each tool will have its pros and cons, no matter what the toolset is, no matter what the project is. I have found that there is not a single tool that is perfect for every project. But finding a good tool that can help in designing the database is a must. If it can even generate code, that is a lot better. One tool that is available that can help with ERD, and generate code, and help with ORM is ORM Designer. And I will examine this tool as it relates to Symfony, CakePHP and non framework applications.

As you have probably noticed, I have integrated a pseudo-Facebook hook into my little Wordpress blog. I am wanting more comments to come thru via Facebook, and am building a full Facebook application that will integrate my posts in a non Wordpress format, link to different resources on command and…
For the past few posts, the main focus has been a NuSOAP Webservice that does really basic things with very limited data. The different functions of the service have done a variety of things:
Although these are very basic and the real world applications are very limited, it can provide a spring board to building real world webservices that can be used for a variety of reasons. But, the power of webservices are that they can be code independent if written correctly. The server portion we have done is all in PHP. The client we have tested this on has been a PHP base. Based on the client functioning properly, we know that PHP based applications will be able to access the data. But the web is not 100% PHP based. Other code exists, which could be .NET flavors, Java, even ColdFusion. We need to ensure that the webservice built will be accepted by applications written in other languages.

OK, the last couple of posts have strayed from the NuSOAP topic. but I wanted to do a quick post before going into to testing the server on a .NET application. The whole point of this post is to modify the result set we are sending back for some of the items. And let’s also change around one of the inputs so it accepts an array of data as the input, instead of strings. Hopefully this example will help others build a NuSOAP server. Which is why I am doing some of these examples. I was tired of seeing example after example of NuSOAP servers with a “Hello World” type of structure. That does not help in the real world. So hopefully these examples will help others.
First, we need to recall our last example we had out there, it was the following files:
Data Used: http://www.hirdweb.com/webservice/items.txt
Server File: http://www.hirdweb.com/webservice/20100720_server.txt
Client File: http://www.hirdweb.com/webservice/20100720.txt
We will be modifying those files, so if you do not already have those, you can grab those there. The data file “items” is ok, and we do not need to change anything there. The server file we will need to change, so go ahead and save that file with a new name. After you do that, you will need to change the line in the server that sets the wsdl address. I named the new file 20100805_server.php.
$wsdl_addr = 'http://www.hirdweb.com/webservice/20100805_server.php';
The first thing to do is change the result set for the showNumbers functions. This is the function that accepts an identifier of 0 thru 5 and returns a list of numbers. It is a pretty simple example. In the real world, the identifier may be a book ISDN, or a product code, or a user id. Based on how you use this, it could return anything, like a list of authors (ISDN), or related products (product code), or friends (user ID). Or this can be used in conjunction with another function. But we need to format this a little better.
