Hello,

I'm creating a page that is bound to a Case Standard Controller and I've created an extension to modify the "New Case" creation process. I want the users to be able to upload an attachment while filling out the New Case details but I've come across an issue. Here is the extension:

public class CaseExt{
    
    public ApexPages.StandardController controller {get;set;}
    public Case c {get;set;}
    public String userEmail;
    Public Attachment a {get;set;}

    public CaseExt(ApexPages.StandardController con){
        controller = con;
        c = (Case) controller.getRecord();
        a = new Attachment();
        userEmail = userInfo.getUserName();
    }
    
    public PageReference save(){
     List<Contact> cnt = [SELECT Id, Email, Name FROM Contact WHERE Email =: userEmail];
        if (cnt.size() < 1) {
            ApexPages.Message msg = new ApexPages.Message(ApexPages.Severity.WARNING, 'Your email address does not match our records. Please update your contact information.');
            ApexPages.addMessage(msg);
            return null;
        } else {
            try {
                c.ContactId = cnt.get(0).Id;
                INSERT c;  
                a.ParentId = c.Id;
                INSERT a;
                return page.CaseThankYou;           
            }catch (Exception e){
            ApexPages.addMessages(e);
            return null;
            }
        }
     }
}

 And the VF page:

<apex:page StandardController="case" extensions="CaseExt">
    <apex:form >
      <apex:pageBlock title="Submit A Case">
        <apex:pageBlockButtons location="bottom">
        <apex:commandButton action="{!save}" value="Submit"/>
        </apex:pageBlockButtons>
        <apex:pageBlockSection columns="1">                     
        <apex:inputfield value="{!c.type}" required="true"/>
        <apex:inputField value="{!c.priority}"/>
        <apex:inputField value="{!c.Subject}" required="true"/>   
        <apex:inputTextarea value="{!c.description}" rows="8" cols="50" />
        <apex:inputfile value="{!a.body}" filename="{!a.name}" />
        </apex:pageBlockSection>
     </apex:pageBlock>
   </apex:form>
</apex:page>

The issue I'm seeing is that when I save the record the attachment doesn't appear to be added to the case.. I can't seem to figure out why. Any help or recommendations are greatly appreciated.

Thank you 

J
