Emailing Visualforce Page Rendering As PDF:

Emailing Visualforce Page Rendering As PDF:

Dynamically choose whether a Visualforce page is rendered as a PDF or not-useful when creating invoices and so on also can email that page using a little Apex code.

public class EmailingVisual { public PageReference getDeliverAsPDF() {

     // Reference the page, pass in a parameter to force PDF

     PageReference pdf =  Page.EmailPage;

     pdf.getParameters().put('p','p');

     pdf.setRedirect(true);

     // Grab it!

    Blob b = pdf.getContent();

     // Create an email

     Messaging.SingleEmailMessage email = new Messaging.SingleEmailMessage();

      email.setSubject('From getDeliverAsPDF!');

     String [] toAddresses = new String[] {'youremailaddress'};

     email.setToAddresses(toAddresses);

     email.setPlainTextBody('Here is the body of the email');

     // Create an email attachment

     Messaging.EmailFileAttachment efa = new Messaging.EmailFileAttachment();

     efa.setFileName('MyPDF.pdf'); // neat - set name of PDF

     efa.setBody(b); //attach the PDF

     email.setFileAttachments(new Messaging.EmailFileAttachment[] {efa});

     // send it, ignoring any errors (bad!)

     Messaging.SendEmailResult [] r =

             Messaging.sendEmail(new Messaging.SingleEmailMessage[] {email});

        return null;

 }}

Then the EmailPage Looks like this and Make sure give your email address in the controller to test this 

<apex:page renderAs="{!if($CurrentPage.parameters.p == null, null, 'pdf')}"

           controller="EmailingVisual">

     <apex:pageBlock title="My Dual-Rendering Invoice">

        <apex:pageBlockSection title="Section 1"> Text </apex:pageBlockSection>

        <apex:pageBlockSection title="Section 2"> Text </apex:pageBlockSection>

    </apex:pageBlock>

             <apex:form >

                <apex:commandLink rendered="{!$CurrentPage.parameters.p == null}"  value="PDF" action="{!getDeliverAsPDF}" ></apex:commandLink>

             </apex:form>

</apex:page>
