Inserting sObject Dynamically in Salesforce

I spend most of my time over Community, best place to learn and share knowledge. There are many questions related to sObject, and out of all a very interesting one is "How I can insert sObject record dynamically?"


I will provide a user interface with two text fields which will take "Object Name" and "Record Name" as string from user. And when I click on Save the record with Name entered should be inserted in the provided Object. Is this possible, of-course it is.


Here is the Visualforce Page code :

<apex:page controller="InsertDynamicSobjectController">
    <apex:form >
        <apex:pageBlock >
            <apex:pageBlockButtons >
                <apex:commandButton value="Save" action="{!Save}"/>
            </apex:pageBlockButtons>
            <apex:pageMessages />
            <apex:pageBlockSection >
                <apex:pageBlockSectionItem >
                    <apex:outputLabel value="Enter Object Name"/>
                    <apex:inputText value="{!ObjectName}"/>
                </apex:pageBlockSectionItem>
                <apex:pageBlockSectionItem >
                    <apex:outputLabel value="Enter Name for Record"/>
                    <apex:inputText value="{!RecordName}"/>
                </apex:pageBlockSectionItem>
            </apex:pageBlockSection>
        </apex:pageBlock>
    </apex:form>
</apex:page>

Here is the Apex Code :

public class InsertDynamicSobjectController
{
    public String ObjectName {get; set;}
    
    public String RecordName {get; set;}
    
    public InsertDynamicSobjectController()
    {
        ObjectName = '' ;
        RecordName = '' ;
    }
    
    public PageReference Save()
    {
        //use GlobalDecribe to get a list of all available Objects
        Map gd = Schema.getGlobalDescribe();
        Set objectKeys = gd.keySet();
        if(objectKeys.contains(Objectname.toLowerCase()))
        {
            try
            {
                //Creating a new sObject
                sObject sObj = Schema.getGlobalDescribe().get(ObjectName).newSObject() ;
                sObj.put('name' , RecordName) ;
                insert sObj ;
                
                PageReference pg = new PageReference('/'+sObj.Id) ;
                return pg ;
            }
            Catch(Exception e)
            {
                ApexPages.addMessages(e) ;
                return null ;
            }
        }
        else
        {
            ApexPages.addmessage(new ApexPages.message(ApexPages.severity.ERROR,'Object API name is invalid')) ;
            return null ;
        }
    }
}
