When case is closed, how to create case comment ??

Hi all,

When I am closing the case, I want to create case comment for that particular case, when I am editing the same closed case I don’t want to create another case comment.

So, can you help me out to write trigger for this.

Hi,

Please try below code
  
trigger CreateCommentOnClose on Case (after update) {
    
    List<CaseComment> lstCommentsToInsert = new List<CaseComment>();
    //Iterate over the cases that are being updated
    for(Case cas : trigger.new){
        if(cas.Status == 'Closed' && trigger.oldMap.get(cas.Id).Status != 'Closed'){
            
            CaseComment comment = new CaseComment();
            comment.ParentId = cas.Id;
            comment.CommentBody = 'Case is Clsoed';
            lstCommentsToInsert.add(comment);
        }
    }
    //Insert Case Comments
    if(!lstCommentsToInsert.isEmpty()){
        insert lstCommentsToInsert;
    }
}

Mark this as "SOLVED" if your query is answered

Thanks,

Give this a try.  This should also take care of the situation where someone marked the case as Closed when creating a case:
  
// Need after insert to get the Case ID to assign to the CaseComment's ParentId field.
// Before insert won't have the Case ID yet.
trigger CaseTrigger on Case (after insert, before update) {

    List<CaseComment> caseCommentList = new List<CaseComment>();
    
    for (Integer i = 0; i < Trigger.New.Size(); i++) {
        Case oldCase = null;
        
        // Before insert won't have Trigger.Old
        if (Trigger.Old != null) {
        	oldCase = Trigger.Old[i];
        }
        
        Case newCase = Trigger.New[i];
        
        if (oldCase == null && newCase.Status == 'Closed' ||
            oldCase != null && oldCase.Status != 'Closed' && newCase.Status == 'Closed') {
            
            CaseComment comment = new CaseComment();
            comment.ParentId = newCase.Id;
            comment.CommentBody = 'Some comment body';
            caseCommentList.Add(comment);
        }
    }
    
    insert caseCommentList;
}
