Create a New Record in Force.com Sites
April 27th, 2010, 10 Comments
So someone asked me yesterday for some code to allow external users to create contact records in Salesforce.com. They needed a simple form where people could enter the details and once submitted receive a confirmation of what information was entered. Here’s what the final page that was developed looks like.

The Salesforce docs for the inputFile Visualforce component has an example of uploading a document using the Standard Controller.

Easily Search and Edit Records with Visualforce
April 7th, 2010, 15 Comments
I tend to over think Visualforce development sometimes and make it harder than it should be. Development with Force.com is surprisingly easy, elegant and quick. For example I recently needed to develop a way for the users to search for records and update specific values. Users should be able to search for records by keyword [...]

I have been working on a Visualforce page that displays a list of items from a collection and I want to display the current row number next to each item. I found this post that describes a solution but I think there may be a bug in one of the components so here is proposed [...]
Passing Parameters with a CommandButton
March 4th, 2010, 9 Comments
This post is a slight tweak of yesterday’s post, Passing Parameters with a CommandLink. In theory you should just be able to switch out the CommandLink component with a CommandButton component and be golden. However, not so fast.

Salesforce.com recently introduced Custom Settings in Winter ’10 which allows you to store custom data sets and associate them on an org-wide, profile or user basis. Custom Settings are essentially custom objects that are exposed in the applications cache and are accessible via their own API. You can certainly build your own custom objects to [...]
Calling a REST Web Service (JSON) with Apex
January 6th, 2010, 8 Comments
Cross-posted at the Appirio Tech Blog. Using JSON RESTful Web Services with Salesforce.com opens up your org to a number third-party integration opportunities (Google, Yahoo!, Flickr, bespoke, etc.). JSON support isn’t baked into the Force.com platform but Ron Hess at Salesforce.com has created a JSON parser which will do the heavy lifting for you. Last [...]

The topic of relationships in Visualforce pages came up on the Salesforce developer discussion boards the other day so I thought I’d throw something together to expand on the topic. Let’s say you want to print off a Sales Order or Purchase Order as a PDF. You can use the parent and child relationships inherent [...]
