Adding Flows to Visualforce Pages

Hi,

To add a flow to a Visualforce page, embed it using the <flow:interview> component:Find the flow's unique name:From Setup, enter Flows in the Quick Find box, then select Flows.
Click the name of the flow that you want to embed.
Define a new Visualforce page or open one that you want to edit.
Add the <flow:interview> component, somewhere between the <apex:page> tags.
Set the name attribute to the unique name of the flow. For example:

<apex:page>
<flow:interview name="MyUniqueFlowName"/>
</apex:page>

If the flow is from a managed package, the name attribute must be in this format: namespace.flowuniquename.

Restrict which users can run the flow by setting the page security for the Visualforce page that contains it.To run the flow, external users (such as on a community) need access to the Visualforce page. To run the flow, internal users need access to the Visualforce page and either:The "Run Flows" permission
The Flow User field enabled on their user detail page

Thanks

Adding some points:

It is not possible to add a Visualforce page within a flow, e.g. there is no way to see it as an option in the Flow Builder. The only method to switch to visualforce is using a page as a wrapper for the flow and passing control to it by setting a variable value within the flow, which there is an example of

Add the following to the controller

public Attachment attachment {
get {
if (attachment == null)
attachment = new Attachment();
return attachment;
}
set;
}

// Specific flow name for flow type
public Flow.Interview.my_flow myflow { get; set; }

public String varCaseId;
public String varUpload;
public Boolean upload;
public Boolean uploaded = false;
public String fName{ get; set;}
public String displayName{get; set;}

// The Case Id value from the flow
public String getvarCaseId()
{
If(myFlow == null)
Return null;
Else
return myflow.varCaseId;
}

// The varUpload variable value from the flow
public String getvarUpload()
{
If(myFlow == null)
Return String.valueOf('0');
Else
Return myflow.varUpload;
}

Public Boolean getupload()
{
If(myFlow != null && myflow.varUpload != null && myflow.varUpload == '1' && uploaded!= null && uploaded == false)
Return true;
else
Return false;
}

// Save method, leading to next step in flow
public PageReference Save()
{
return upload(System.Boolean.valueOf(true));
}

// Save More method, leading to the attachment upload functionality again
public PageReference SaveMore()
{
return upload(System.Boolean.valueOf(false));
}

// Cancel method, leading to next step in flow
public PageReference Cancel()
{
This.uploaded = true;
attachment = null;
return null;
}

// Upload method for actual attachment upload, setting the upload variable appropriately to allow/ not allow another attachment upload
public PageReference upload(Boolean varUploaded)
{
attachment.OwnerId = UserInfo.getUserId();
attachment.ParentId = getvarCaseId(); // the record the file is attached to
attachment.IsPrivate = false;

if( (!(attachment.name != null && attachment.name != '')) && (fName != null && fName != ''))
{
String afterExt = fName.substringAfter('.');
System.debug('afterExt :: ' + afterExt );
if(displayName != null && displayName != '')
{
attachment.name = displayName + '.' + afterExt;
}
else
attachment.name = fName;
}
try
{
if(!(attachment.body != null))
{
ApexPages.addMessage(new ApexPages.message(ApexPages.severity.ERROR, 'Please specify a file to be uploaded'));
}
else if (!(attachment.name != null && attachment.name != ''))
{
ApexPages.addMessage(new ApexPages.message(ApexPages.severity.INFO, 'Please specify a file name'));
}

insert attachment;
displayName = '';
fName = '';

}
catch (DMLException e)
{
ApexPages.addMessage(new ApexPages.message(ApexPages.severity.ERROR,'Error uploading attachment'));
return null;
}
finally
{
attachment = new Attachment();
}

This.uploaded = varUploaded;
// true for save and false for Save more
return null;

// End of upload
}
Visualforce page

<apex:outputPanel id="theAttachmentPanel" rendered="{!upload}">
<apex:sectionHeader title="Attachment Upload (Upto 10 MB)"/>

<apex:pageMessages />
<apex:pageBlock title="Upload an Attachment">

<apex:pageBlockButtons >
<apex:commandButton action="{!SaveMore}" value="Upload More"/>
<apex:commandButton action="{!Save}" value="Finish Uploading"/>
<apex:commandButton action="{!Cancel}" value="Submit with no Attachment"/>
</apex:pageBlockButtons>

<apex:pageBlockSection showHeader="false" columns="2" id="block1">

<apex:pageBlockSectionItem >
<apex:outputLabel value="File Name" for=" filesName "/>
<apex:inputText value="{!displayName}" id="filesName"/>
</apex:pageBlockSectionItem>

<apex:pageBlockSectionItem >
<apex:outputLabel value="File" for="file"/>
<apex:inputFile value="{!attachment.body}" filename="{!fName}" id="file"/>
</apex:pageBlockSectionItem>

<apex:pageBlockSectionItem >
<apex:outputLabel value="Description" for="description"/>
<apex:inputTextarea value="{!attachment.description}" id="description"/>
</apex:pageBlockSectionItem>

</apex:pageBlockSection>
</apex:pageBlock>

Hope this will help you.

Thanks
