How to get the picklist value in Salesforce Apex class?

Hi Saurabh,

To get picklist values in Apex is very simple. I am sharing some code, please go through this:

Here is My Controller

public class testclass {
    public Job__c job {get;set;}
    public List<SelectOption> options{get;set;}
    public testclass() {
        options = new List<SelectOption>();
        Schema.DescribeFieldResult fieldResult = Job__c.Status__c.getDescribe();
        List<Schema.PicklistEntry> ple = fieldResult.getPicklistValues();
        for( Schema.PicklistEntry f : ple) {
            options.add(new SelectOption(f.getLabel(), f.getValue()));
        }
    }
}

My Page

<apex:page controller="testclass">
    <apex:form>
        <apex:pageBlock>
            Order Status:<apex:selectList id="countries" value="{!job.Status__c}" size="1" required="true">
                <apex:selectOptions value="{!options}"/>
            </apex:selectList>
        </apex:pageBlock>
    </apex:form>
</apex:page>

Thanks.

Hi,

Using Dynamic apex, we can achieve this. On object of type pickilist, call getDescribe(). Then call the getPicklistValues() method. Iterate over result and create a list. Bind it to <apex:selectOptions>.

Code Example:

Let’s say we have a custom object called OfficeLocation__c. This object contains a picklist field Country__c.

The first thing we need to do, within our controller is use the getDescribe() method to obtain information on

the Country__c field:

Schema.DescribeFieldResult fieldResult = OfficeLocation__c.Country__c.getDEscribe();

We know that Country__c is a picklist, so we want to retrieve the picklist values:

List<Schema.PicklistEntry> ple = fieldResult.gerPicklistValues();

The only thing left for us to do is map the picklist values into an <apex:selectOptions> tag can use for display. Here is the entire method from our controller to do this:

public List<SelectOption> getCountries()
{
    List<SelectOption> options = new List<SelectOption>();
    Schema.DescribeFieldResult fieldResult = OfficeLocation__c.Country__c.getDescribe();
    List<Schema.PicklistEntry> ple = fieldResult.getPicklistValues();
    for(Schema.PicklistEntry f : ple)
    {
        options.add(new SelectOption(f.getLabel(), f.getValue()));
    }
    return options;
}

With our controller logic all complete, we can call the getCountries() method from our Visualforce page,  and populate the <apex:selectList> tag:

<apex:selectList id=”countries” value=”{!Office_Location__c.Country__c}” size=”1″ required=”true”>
    <apex:selectOptions value=”{!countries}”/>
</apex:selectList>

Thanks
