How to use apex variable for total records in Visualforce

Scenario:
  I came across a issue where visualforce does not allow one to Count or Sum records in a page.
One solution would be to add more code to the controller to do a count of the records. Which is ok.
A simple solution is to use the apex variable function in Visualforce.

Solution:

1. Lets do it off Contacts
2. In your Apex Controller : Create a SOQL query as is:

public class countcontroller{

            public List<Contact> queryResult {get;private set;}

            public String qryString {get;set;}

            public PageReference query(){

            qryString =  'SELECT Name, Email, Phone from Contact';

            queryResult = Database.query(qryString);
             return null;

       }

} 

Pretty Simple and Straight Forward.

Now for the VF Page and Magic:

You will see I use the apex variable function to do a couple of things:

• 
  

  create a variable

  run the query inside that variable counting all the records by 1 within a repeat tag

  calling the variable with the total 

  Kind of like a for Loop but in Visualforce instead of controller. 

<apex:page standardcontroller="Contact" extensions="countcontroller">

<table width="95%" border="0" align="center" cellpadding="0" cellspacing="0">
<tr height="5">
    <td width="35%" class="outsideround_head" align="right">
        Total Contacts Returned:&nbsp;
    </td>
    <td width="8%" class="outside_round_head_value">
        <apex:variable var="call" value="{!0}" />
        <apex:repeat var="countitall" value="{!queryResult}" >
        <apex:variable var="call" value="{!call+1}"/>
        </apex:repeat>
        <apex:outputText value="{!call}"/>
    </td>

</tr>

</table>

</apex:page>

Wallah you have count.

How do I add VF Page to Account Page Layout??

Hi:
Welcome back...
Let say you created a Visual Force Page and Apex Controller... Now you want to add the VF page to the Page Layout on for example Account. So when an user goes into an Account; he/she will see the Visual Force Page created.
But, there is no option there on the account Page Layout to add VF pages...
Now what?
Well very easy, The solution is:
VF pages will show up in the Page Layout editor if there is at least one VF Page using the standard controller for Account (in your scenario).
The VF page you want to add to the Account page layout must use the Account standard controller.
For example in your Visual Force Page First line should have the standard Controller connected to the object:

Make sure you create the apex method in your Apex class....
