Help with updated selected record field values from lightning component

Question

Could someone please help me with updating the selected Opportunity records with the desired field values from hasRecordId. I have created a lightning component on an opportunity record to display all the related records using a checkbox table. I need these selected records to update with the field values for Check_In_Date__c and Check_Out_Date__c from the hasrecordId on the click of the "Update" button. I have been stuck on this for a while, any help would be appreciated.

This is my apex and controller code I have so far but it is not successfully updating my selected checkbox records.

APEX:

     @AuraEnabled
public static void updateRecord(List <String> lstRecordId, String oppRecordId) {
    
    List<Opportunity> lstUpdate = new List<Opportunity>();
    
    for(Opportunity Opp : [SELECT Id, Name, Check_In_Date__c, Check_Out_Date__c, Total_Amount__c, Deposit_Amount__c, SyncedQuoteId 
                           FROM Opportunity 
                           WHERE Id IN : lstRecordId]){
    lstUpdate.add(Opp);
    }
    
    if(lstUpdate.size() > 0){
        UPDATE lstUpdate;
        
    } 

CONTROLLER:

       updateFields: function(component, event, helper) {
    var updateId = [];
    var getAllId = component.find("boxPack");
    var recordId = component.get('v.recordId');
    
    if(! Array.isArray(getAllId)){
        if (getAllId.get("v.value") == true) {
            updateId.push(getAllId.get("v.text"));
        }
    }else{
        
        for (var i = 0; i < getAllId.length; i++) {
            if (getAllId[i].get("v.value") == true) {
                updateId.push(getAllId[i].get("v.text"));
            }
        } 
    } 

    var action = component.get('c.updateRecord');
    action.setParams({
        "lstRecordId":updateId, 
        "oppRecordId":recordId});

    action.setCallback(this, function(response) {
        
        var state = response.getState();
        if (state === "SUCCESS") {
            console.log(state);

            $A.get('e.force:refreshView').fire();
            $A.get("e.force:closeQuickAction").fire();
        }
    });

    $A.enqueueAction(action);

},  
 });

UPDATE/FURTHER EXPLANATION:

I have created an aura lightning component on my 'Lead PAX' opportunity record type which shows the related 'Child PAX' opportunity records (lstRecordId) in a checkbox list. I need the fields Check_In_Date__c, Check_Out_Date__c, Total_Amount__c, Deposit_Amount__c to populate with the field values from hasRecordId (oppRecordId) which is the record with my lightning component on it. How do I change the code below so that instead of populating the values I have written into my code, it populates the values from oppRecordId?

    @AuraEnabled
public static void updateRecord(List <String> lstRecordId, String oppRecordId) {
    
    List<Opportunity> lstUpdate = new List<Opportunity>();
    
    for(Opportunity Opp : [SELECT Id, Name, Check_In_Date__c, Check_Out_Date__c, Total_Amount__c, Deposit_Amount__c, SyncedQuoteId 
                           FROM Opportunity 
                           WHERE Id IN : lstRecordId]){
                               Opp.Check_In_Date__c = date.parse('03/02/2021');
                               Opp.Check_Out_Date__c = date.parse('03/02/2021');
                               Opp.Total_Amount__c = decimal.valueof('2281.90');
                               Opp.Deposit_Amount__c = decimal.valueof('200.00');
                               
    lstUpdate.add(Opp);
    }
    
    if(lstUpdate.size() > 0){
        update lstUpdate;
        
    }

Answer 1

force:hasRecordId only provides the record id, i.e Id field of the record that you're viewing. If you need additional fields you need to fetch it explicitly. I've modified your Apex controller to fetch Check in and Check out dates for the hasRecordId record. Let me know if this works out for you.

@AuraEnabled
public static void updateRecord(List <String> lstRecordId, String oppRecordId) {

   Set<String> oppoIds = new Set<String>(lstRecordId);
   oppoIds.add(oppRecordId);
   Map<Id,Opportunity> oppoMap = new Map<Id,Opportunity>([SELECT Id, Name, Check_In_Date__c, Check_Out_Date__c, Total_Amount__c, Deposit_Amount__c, SyncedQuoteId 
                       FROM Opportunity 
                       WHERE Id IN : oppoIds]);

   Opportunity referenceOppo = oppoMap.get(oppRecordId);

   List<Opportunity> lstUpdate = new List<Opportunity>();

   for(Opportunity Opp : oppoMap.values()){
       if(Opp.Id==oppRecordId) continue;
       Opp.Check_In_Date__c = referenceOppo.Check_In_Date__c;
       Opp.Check_Out_Date__c = referenceOppo.Check_Out_Date__c;
       lstUpdate.add(Opp);
   }

   if(lstUpdate.size() > 0){
       UPDATE lstUpdate;
   } 
}

Can you please provide the HTML?

In the Callback, I don't see the value of an Attribute being Set, so I don't see any update to the data on the page.

The Apex Controller's return type is Void so you don't return data to your LWC but you update the Database with a DML Update call. This Update will not show up unless you re-query the Database for it or you pass back the new value in the Callback.
