Hello Everyone,

I am working on one visualforce page where I have a text field and save button, on entering data to text field and clicking on save button, I am creating the record.

Now I want to show the newly inserted record on vf page in a table, I did created vf page and apex class but unable to show the created record on vf page.

Can anyone helps me out in this issue if possible.

Visualforce Page:

<apex:page Controller="StagingEventInsertAndShowData" lightningStylesheets="true">
    <apex:form >
        <apex:pageMessages id="pageMessages"/>
        <apex:pageBlock title="New Staging Event Attendee">
            <apex:pageBlockSection id="reRenderId">
                <apex:inputText label="Barcode" value="{!Barcode}"/>
                <apex:commandButton value="Insert" action="{!save}" reRender="reRenderId,pageBlockRecords,pageMessages"/>
            </apex:pageBlockSection>
        </apex:pageBlock>
        <apex:pageBlock title="Details of Attendees" id="pageBlockRecords">
            <apex:pageBlockTable value="{!accList}" var="a">
                <apex:column headerValue="Barcode" value="{!a.Barcode__c}"/>
                <apex:column headerValue="Attendant" value="{!a.Attendant__c}"/>
                <apex:column headerValue="Campaign" value="{!a.Campaign_ID__c}"/>
                <apex:column headerValue="Email" value="{!a.Email__c}"/>
                <apex:column headerValue="Date Attended" value="{!a.Date_Attended__c}"/>
                <apex:column headerValue="Invalid Barcode" value="{!a.Invalid_Barcode__c}"/>
            </apex:pageBlockTable>
        </apex:pageBlock>
    </apex:form>
</apex:page>

Controller:

public class StagingEventInsertAndShowData {
    public String Barcode{get;set;}
    public List<Staging_Event_Attendee__c> accList {get;set;}

    public StagingEventInsertAndShowData(){
        getStagingRecords();
    }

    public void getStagingRecords(){
        Date todayDate = Date.today() ;
        accList=[SELECT Id,Name,Barcode__c,Attendant__c,Campaign_ID__c,Email__c,Date_Attended__c,Invalid_Barcode__c FROM Staging_Event_Attendee__c LIMIT 10];
    }

    public PageReference save() {
        if(string.isNotBlank(Barcode)){
            Staging_Event_Attendee__c ac = new Staging_Event_Attendee__c();
            ac.Barcode__c = Barcode;
            insert ac;
            this.Barcode = null;
            ApexPages.addMessage(new ApexPages.Message(ApexPages.Severity.CONFIRM , 'Saved Successfully'));
            getStagingRecords();
        } else {
            ApexPages.addMessage(new ApexPages.Message(ApexPages.Severity.Error, 'Barcode was left blank. Please enter a barcode'));
        }
        return null;
    }
}
