formSubmission = insertFormSubmission(formSubmissionData); 

from this map , loop on this map keyset and populate the form_submission record.

Form_Submission__c formSubmission = new Form_Submission__c( 
    Contact__c = formSubmissionData.get('contactId'),
    Enrollment__c = formSubmissionData.get('enrollmentId'),      
);*/
insert formSubmission;

i tried in this way i'm getting error , can any one help me?

Form_Submission__c formSubmission = new Form_Submission__c();
for( string fs:formSubmissionData.keyset())
{
  formSubmission.fs =formSubmissionData.get(fs);
 }
insert formSubmission;

Answer 1

You can't refer to properties dynamically like that in Apex.

formSubmission.fs =formSubmissionData.get(fs);

If you want to place a value in the field whose name corresponds to the content of the variable fs, you must use the put() method.

formSubmission.put(fs, formSubmissionData.get(fs));

Answer 2

You can not use fs like this dynamically in apex. formSubmission.fs =formSubmissionData.get(fs); Use formSubmission.put(fs,formSubmissionData.get(fs)).

Answer 3

In your first solution, you had an extra comma right before your closing paren ,) for the constructor of you sObject Form_Submission__c. I have fixed it here:

Form_Submission__c formSubmission = new Form_Submission__c(Contact__c = formSubmissionData.get('contactId'),
                                                            Enrollment__c = formSubmissionData.get('enrollmentId'));
insert formSubmission;

Answer 4

formSubmission.fs =formSubmissionData.get(fs);

In above code you are setting formSubmission.fs , if fs is a field in object Form_Submission__c then your code will work fine.

This explanation based on the code you have given plz update the full code to understand your exact problem.
