How to pass a table's row from Visualforce to a controller extension
I want to make a VF page that shows members of a campaign as well as has a searchfield to find contacts to add to the campaign. So the action for the search field will find all contacts that match and display them on a list. Then the user can select a contact and click on the name and that contact would be added to the campaign.
My problem is that I don't know how to implement that last bit. Since the list of contats is displayed with a pageBlockTable how does the controller know which contact was selected.
Here is my VF page markup
<apex:page standardController="Campaign" extensions="showCampaignMembers">
<apex:form >
<apex:pageBlock title="{!campaign.name}">
<apex:pageBlockSection title="Criteria">
<apex:outputLabel value="Enter Name Snippet"/>
<apex:inputText value="{!nameQuery}"/>
<apex:commandButton action="{!executeSearch}" value="Search"/>
</apex:pageBlockSection>
<apex:pageBlockTable value="{!contacts}" var="con">
<apex:column headerValue="Name">
<apex:outputLink value="/{!con.id}/e?retURL={!URLENCODE('/apex/RetUrlSearchPage?query='+nameQuery)}">{!con.Name}</apex:outputLink>
</apex:column>
<apex:column value="{!con.Participant__c}"/>
</apex:pageBlockTable>
<apex:pageBlockSection title="Participants in Campaign">
<apex:pageBlockTable value="{!participants}" var="part">
<apex:column value="{!part.FirstName}"/>
<apex:column value="{!part.LastName}"/>
<apex:column value="{!part.Email}"/>
<apex:column value="{!part.Status}"/>
</apex:pageBlockTable>
</apex:pageBlockSection>
</apex:pageBlock>
</apex:form>
</apex:page>
-----------
And the controller
-----------
public class showCampaignMembers
{
public String nameQuery {get; set;}
public List<Contact> contacts {get; set;}
Public List<CampaignMember> participants {get; set;}
private ApexPages.StandardController std;
public PageReference executeSearch()
{
String queryStr='%' + nameQuery + '%';
contacts=[select id, Name, Participant__c
from Contact
where name like :queryStr];
return null;
}
public showCampaignMembers(ApexPages.StandardController stdCtrl)
{
Std = stdCtrl;
Participants = [SELECT id, FirstName, LastName, Email, Status FROM CampaignMember
WHERE CampaignId = :std.getId() ORDER BY FirstName];
}
}
I appreciate any help.

Your requirement can be fulfilled by using a wrapper class. Below is the code example of a requirement where a list of accounts will be displayed on vf page along with a checkbox on each row. When user selects the particular records, the controller will have a all records but you can distinguish with the help of checkbox true and false.
<apex:page controller="AccountSelectClassController" sidebar="false"> <script type="text/javascript"> function selectAllCheckboxes(obj,receivedInputID){ var inputCheckBox = document.getElementsByTagName("input"); for(var i=0; i<inputCheckBox.length; i++){ if(inputCheckBox[i].id.indexOf(receivedInputID)!=-1){ inputCheckBox[i].checked = obj.checked; } } } </script> <apex:form > <apex:pageBlock > <apex:pageBlockButtons > <apex:commandButton value="Show Selected Accounts" action="{!processSelected}" rerender="table2"/> </apex:pageBlockButtons> <apex:pageblockSection title="All Accounts" collapsible="false" columns="2"> <apex:pageBlockTable value="{!wrapAccountList}" var="accWrap" id="table" title="All Accounts"> <apex:column > <apex:facet name="header"> <apex:inputCheckbox onclick="selectAllCheckboxes(this,'inputId')"/> </apex:facet> <apex:inputCheckbox value="{!accWrap.selected}" id="inputId"/> </apex:column> <apex:column value="{!accWrap.acc.Name}" /> <apex:column value="{!accWrap.acc.BillingState}" /> <apex:column value="{!accWrap.acc.Phone}" /> </apex:pageBlockTable> <apex:pageBlockTable value="{!selectedAccounts}" var="c" id="table2" title="Selected Accounts"> <apex:column value="{!c.Name}" headerValue="Account Name"/> <apex:column value="{!c.BillingState}" headerValue="Billing State"/> <apex:column value="{!c.Phone}" headerValue="Phone"/> </apex:pageBlockTable> </apex:pageblockSection> </apex:pageBlock> </apex:form> </apex:page>public class AccountSelectClassController{ //Our collection of the class/wrapper objects wrapAccount public List<wrapAccount> wrapAccountList {get; set;} public List<Account> selectedAccounts{get;set;} public AccountSelectClassController(){ if(wrapAccountList == null) { wrapAccountList = new List<wrapAccount>(); for(Account a: [select Id, Name,BillingState, Website, Phone from Account limit 10]) { // As each Account is processed we create a new wrapAccount object and add it to the wrapAccountList wrapAccountList.add(new wrapAccount(a)); } } } public void processSelected() { selectedAccounts = new List<Account>(); for(wrapAccount wrapAccountObj : wrapAccountList) { if(wrapAccountObj.selected == true) { selectedAccounts.add(wrapAccountObj.acc); } } } // This is our wrapper/container class. In this example a wrapper class contains both the standard salesforce object Account and a Boolean value public class wrapAccount { public Account acc {get; set;} public Boolean selected {get; set;} public wrapAccount(Account a) { acc = a; selected = false; } } }Hit thumbsup if it helps
