In my visualforce page I have a field 'Fruits', which has 4 checkboxes 'Apple', 'Orange', 'Grapes', and 'Kiwi' as options under it. I can select multiple options. Now in my controller I want to save the selected values to a multiselect picklist 'Fruit__c' in the 'Tree__c' object. How can I do it?

These 4 checkboxes, are they HTML checkboxes or apex:inputCheckbox? – Boris Bachovski Feb 3 '15 at 4:55

@Bachovski apex:inputCheckbox – Knowme Feb 3 '15 at 4:59

@VamsiKrishna I saw that, but it doesn't solve my issues of saving the values to a multi select picklist. – Knowme Feb 3 '15 at 6:13

Let's assume you have 4 boolean varialbes for each of the checkboxes in order to determine which one is selected:
public boolean apple {get; set;}
public boolean orange {get; set;}
public boolean grapes {get; set;}
public boolean kiwi {get; set;}
In your save method you can check which of the 4 is selected and build a semi-colon separated string with the values (it's how multi-select picklists store the values):
public void save()
{
String selectedFruits = '';
selectedFruits += apple == true ? 'Apple;' : '';
selectedFruits += orange == true ? 'Orange;' : '';
selectedFruits += grapes == true ? 'Grapes;' : '';
selectedFruits += kiwi == true ? 'Kiwi;' : '';
Tree__c treeRecord = new Tree__c();
treeRecord.Fruit__c = selectedFruits;
// set other fields
insert treeRecord;
}

Thanks Bachovski! Good point to know, that multilist picklists are stored as semi-colon separated values. Now what if I have 15 options instead of 4? – Knowme Feb 3 '15 at 6:11

Same thing just keep appending to the string, having every selected value followed by a semi colon. Alternatively you can just expose that multipicklist field on the page and don't worry about all this. If you have limitations around that then have a look at this multi select component - github.com/metadaddy-sfdc/Visualforce-Multiselect-Picklist – Boris Bachovski Feb 3 '15 at 6:15

Got it, thanks! :) But in my real case, I have 4 such fields with 15 options each! I feel there should be an effective way to do this?? – Knowme Feb 3 '15 at 16:54

Also I think the whole scenario will give you a better understanding. So there is one more object called Earth__c, where these 4 fields with their options are defined. I created those 4 fields in Fruit__c. Now In my controller, I am getting the options for the fields in Fruit__c from the fields in Earth__c, and displaying them on the visualforce page. I want the selected values on the visualforce page to be saved in the fields on Fruit__c. Please let me know if you have more questions on this. – Knowme Feb 3 '15 at 17:06

@Knowme so does that mean that Earth__c and Fruit__c both fields have the same values? – Boris Bachovski Feb 3 '15 at 22:19
