Field sets are well documented in the Salesforce help, so I won't reproduce any of that here. Instead, here's an example using field sets to create an edit page with additional Visualforce functionality.
Firstly, I've created two Field Sets on the Account standard object. The first is for general fields that I'll show at the top of the record:
While the second is for Address-specific fields:
Next I create my Visualforce page. The key markup is as follows:
<apex:pageBlock mode="maindetail" title="Account Edit">
<apex:pageBlockButtons >
<apex:commandButton value="Cancel" action="{!cancel}"/>
<apex:commandButton value="Save" action="{!save}"/>
</apex:pageBlockButtons>
<apex:pageBlockSection title="General">
<apex:repeat value="{!$ObjectType.Account.FieldSets.General}"
var="field">
<apex:inputField value="{!Account[field]}" />
</apex:repeat>
</apex:pageBlockSection>
<apex:pageBlockSection title="Address">
<apex:repeat value="{!$ObjectType.Account.FieldSets.Address}"
var="field">
<apex:inputField value="{!Account[field]}" />
</apex:repeat>
</apex:pageBlockSection>
<apex:pageBlockSection title="Bar Chart">
<div id="barchart" style="width: 450px; height: 25px;"></div>
</apex:pageBlockSection>
</apex:pageBlock>
Using the field set is as simple as accessing it from the $ObjectType global variable and iterating the fields:
<apex:repeat value="{!$ObjectType.Account.FieldSets.Address}"
var="field">
<apex:inputField value="{!Account[field]}" />
</apex:repeat>
The additional Visualforce functionality is a simple Dojo barchart, which is drawn in by Javascript into the barchart div.
Here's the generated page:
As an Administrator, if I then decide that I'd like to add the Industry field to the page. I simply edit my General Field Set to add the field to the end of the set, refresh the page, and the new field is present with zero coding effort:
I've already used this in one solution that combines record creation with embedded searching capabilities.
Is there a way you can pass a fieldset name from a controller extension to the apex:repeat in the above example?
ReplyDeleteNot as far as I know. There's a Force.com blog post on field sets at http://blog.sforce.com/sforce/2011/02/using-field-sets-in-spring-11.html and the author states that fieldset metadata is not available in Apex at present.
ReplyDeleteSorry for my English. In the sets of fields could put Will masks or certain values, for example, a single field number in the Visualforce code without having to put it when you create a field in salesforce?. It would be like when we put the Required = (var.requiered) to a InputField to only leave the fields that are mandatory salesforce. Or put them in serious SOLUTIONS salesforce to create the fields and create code so that only leaves predeteminados values according to the profile or page layout. Thanks

ReplyDeleteDo you know how to get this to work with web to lead? Is it possible with the use of an extension to the standard Lead controller?
ReplyDeleteYou won't be able to use this for web to lead, as that is an HTML form that hits a particular servlet rather than Visualforce.
ReplyDeleteYou could certainly create a lead capture visualforce page, but you'd have to make this available via an unauthenticated Force.com site for it to work like web to lead.
I have a field set, but one is input field other is plain output text field. How can I have these 2 fields in a field set?
ReplyDeleteField sets just contain fields. You add the input/output behaviour on the page. Maybe you should have two field sets - one for inputs and one for outputs,

Delete@Bob: That's generally correct, but I think you could make this work if you added some logic to the VF Page (and/or its controller extension) that would tell you if a field should be input or output. For example, you could probably wrap them into an , and always render just one field, with rendered="{!f.Label=='JustShowMe'}", rendered="{!f.readOnly}", or something like that (for the latter, you would have to get the fields from the controller via an extended List method). http://www.salesforce.com/us/developer/docs/pages/Content/pages_dynamic_vf_field_sets.htm should get @Mitesh on the right path. I've never tried this, but I think I will. Stay tuned...
Deletedarn, the tags were removed: I meant to say: wrap them into an outputPanel and extend "List < Schema.FieldSetMember > " method.
DeleteAre there any known limitations as to what the end user can and cannot do with field sets? The questions that come to mind are:
ReplyDelete- can the customer's admin add new fields that were created at the customer's site, outside of the managed package, so that these are also rendered on the packaged VF Page?
- is there a way to prevent customers from removing specific fields, because they may be tied to some internal logic?
I just found out myself: end users can indeed add their custom fields to one of our field sets and have them properly rendered on our VF Page (which actually is the whole point of using fields sets for me). There's an important thing to know about the "Required" flag on fields in a field set, though: end users can remove required fields from the field set, but they can't change the field's required flag from true to false. But of course you could offer two field sets, if you need to be flexible: one having a field in it as required, and another where the flag for the same field is set to false. This would allow the end user to add the field to one set, and remove it from the other, as needed. This may force you into some awkward VF design, though.
DeleteIs it possible to show a custom field label instead of object field label, Say I have created a filed with a label as 'Name', but I want to display the label as 'First Name' in VF by using fieldsets
ReplyDeleteI tried your example and got the following error:
ReplyDeleteError: apex:commandButton must occur between tags
That isn't a full example - the snippet is the key markup, so you'll need to wrap it in apex:form tags (and possibly others).
DeleteI created fields using metadata api in an visualforce page how to display these fields dynamically in an visualforce page.
ReplyDeleteplease help me...
I can't find a way to insert the field values of the parent object that are being used in the fieldset on the child object. Below is my code and I get the null values. I can only successfully insert the values in the Job object. Not sure if my approach is correct to use the parent object fields in the child fieldset.
ReplyDeletepublic with sharing class fieldsetJobApplication
{
// Job object has a lookup to the Candidate object
// The fieldset is on the Job object and is referring few fields on the Candidate object
// From the VF page on insert the values into the Job object are inserted fine but the fieldset values on the Candidate object remain null
public Job__c jA {get;set;}
public Candidate__c jC {get;set;}
public fieldsetJobApplication()
{
jA = new Job__c();
jC = new Candidate__c();
}
public PageReference save()
{
assignValues();
// Insert Candidate record
insert jC;
// Provide the parent Id to child record for reference
jA.Candidate__c = jC.Id;
// All below show as null values on System.debug
System.debug('jA.Interviewer__c : ' + jA.Candidate__r.Interviewer__c);
System.debug('jA.Start_Date__c : ' + jA.Candidate__r.Start_Date__c);
System.debug('jA.Education__c : ' + jA.Candidate__r.Education__c);
System.debug('jC.Interviewer__c : ' + jC.Interviewer__c);
System.debug('jC.Start_Date__c : ' + jC.Start_Date__c);
System.debug('jC.Education__c : ' + jC.Education__c);
insert jA;
return new pagereference('/'+jA.id);
}
public List getFldsJA()
{
return SObjectType.Job__c.FieldSets.JA_Fieldset.getFields();
}
}
// VF Markup
Have you ever got solution for this.

ReplyDeleteHow to render fieldsets in visualforce page when checkbox is clicked ? If checkbox is checked it should render fieldset "propername" else it should render fieldset "Unusualname".
ReplyDeleteBoth fieldset are created on Standard Object "Contact".
Hi Bob, quick question. If a field set contains a reference and it is loaded into columns using repeats, that reference field displays as a hyperlink. Is there any way to remove the hyperlink portion and just keep the text?
ReplyDeleteI figured it out, it looks like you can access all the fields in the references in the field set.
