Visual Contacts with Visualforce & CSS3

I’ve been working on code and content updates to our Force.com Architecture Workshop over the past few weeks. Today I was working on the Visualforce section. It’s easy to forget that Visualforce is a container for just about any web library you can think of. Too often we get stuck on the 80+ tags provided by Salesforce. But in the world of jQuery, HTML5, CSS3 etc, we can do some really cool things.

I’ll be the first to admit I am not a ‘scripting’ expert, but it doesn’t take much work to combine some style, with Salesforce data to produce something like this:

The effect is pretty cool, and amazingly simple to do. Let’s start with the controller extension. There is nothing fancy here, just grab all the Contacts for a particular Account:

public class AccountsVisualContacts {

    public Account acct {get; set;}
    public Id acctid {get; set;}
    public List<Contact> allContacts { get; set;}

     public AccountsVisualContacts(ApexPages.StandardController stdController) {
        this.acct = (Account)stdController.getRecord();
         allContacts = [select id, Name, FirstName, LastName, Wiki_Link__c, Image_URL__c from Contact where Accountid = :acct.id];
    }
}

Now, we can add the Visualforce page. I ‘borrowed’ the CSS from the net, and added it to the top of my Visualforce page. The rest of the code is leveraging the styles defined within an apex:repeat tag. The only other trick here to include a variable to dynamically increment a counter to allow me to reference the correct CSS style. For this simple example, I am using a predefined number of styles, but there is no reason I could not use the same incrementing variable trick to dynamically set the width and height of my polaroids.

You will also notice that I am using the standard Account controller, and my custom controller as an extension. Using the standard Account controller allows me to link directly to my Visualforce page from a custom button on the Account layout. We’ll see why this is important a bit later. I also added a custom field on the Contact object, Image_URL__c to point to an image source on the internet (specifically, images from wikipedia as we can be pretty comfortable they are not going anywhere)

        <apex:variable var="count" value="{!count + 1}"/>
        </apex:repeat>

    </div>

</apex:page>

Ok, all the hard stuff is done. All that is left is to add a custom button to our Account Details, and point it to the Visualforce page:

That’s it. Load this into your Salesforce org, and you are good to go!
