Git fork sync

Git command to fork sync:

1. git fetch upstream
2. git merge upstream / branch_name
3. git push origin branch_name [optional, if you want to update your account remote]

Note : if you did not add upstream as remote then add by below command:
git remote add upstream(remote_name)  remote_url

Basic :  if you don't know, which one is origin and which one is upstream then read below:

After forking repo, that repo will come to your account and that is ORIGIN and UPSTREAM is which you have forked from. Like:

Another account / repo (upstream) => forked => your account / forked repo (origin)

pass more than one value to next kendodropdownlist by filter

see the below code to do this:

var branch_dropdown_id = $("#branch_id").kendoDropDownList({
                optionLabel:"--Select Branch--",
                dataTextField:"name",
                dataValueField:"branch_id",
                dataSource:{
                    serverFiltering:true,
                    transport:{
                        read:{
                            dataType: "json",
                            type: "POST",
                            url: url
                        }
                    }
                },
                change:function(e){
                    $("#class_id").data("kendoDropDownList").enable();
                    $scope.branid = this.value();
                    var classid = $("#class_id").data("kendoDropDownList");
   
                    classid.dataSource.filter({
                        field: "branch_id",
                        value: this.value(),
                        operator: "eq"
                    });
                    classid.value(0);                                       
                }
            }).data("kendoDropDownList");

var class_id = $("#class_id").kendoDropDownList({
                autoBind:false,
                optionLabel:"--Select Class--",
                dataTextField:"class_name",
                dataValueField:"class_id",
                dataSource:{
                    serverFiltering:true,
                    transport:{
                        read:{
                            dataType: "json",
                            type: "POST",
                            url: url
                        }
                    }
                },
                change:function(e){
                    $("#section_id").data("kendoDropDownList").enable();                       
                    var sectionid = $("#section_id").data("kendoDropDownList");   
                    sectionid.dataSource.filter({
                        field: "classid",
                        value: this.value(),
                        operator: "eq",
                        field1: "bnid",
                        value1: branch_dropdown_id.value(),
                        operator1: "eq"
                    });                   
                    sectionid.value(0);
                }
            });

easy differences between innodb and myisam storage engine

1.InnoDB: InnoDB works on relational database way.
example: if you create two tables and create a relation first table to second table like first table has a primary key and second table has a foreign key, now if anyone wants to delete first table row then mysql will throw an error, as mysql won't accept this type of deletion.
1. MyISAM: MyISAM does not care about relational way.
example: in MyISAM you can delete the primary row/ parent data. in this way mysql will accept it.

----------------------------------------------------------------------------------------------------------
2. InnoDB: InnoDB works in row block way.
2. MyISAM: MyISAM works in table block way.

----------------------------------------------------------------------------------------------------------
3. InnoDB is good for write operation[insert, update, delete].
3. MyISAM is faster in read operation[fetching data].

set flash data in codeigniter

first go to your controller: e.g mycontroller.php and think this is a method your form will post into it:
------------------------------------------------
public function submitData(){
        $my_input = $this->input->post('form_input_name');

        /******insert these data to database************/
 $insertJournalDrData = array(
                "field_name" => $my_input
                 );
    $ledger_id=$this->Model->isnertData('tableName',$insertData);
      /********end of insertion in database***********/
        $this->session->set_flashdata('success_message','Data Saved Successfully!');
        redirect('mycontroller');
    }

secondly, your view will be like this:
--------------------------------------------------
<?php if ($this->session->flashdata('success_message') != ''):?>
      <div class="alert alert-success" role="alert">
             <?php echo $this->session->flashdata('success_message');?>
       </div>
<?php endif;?>

Note: here database is not important, you can do it without database.

calendar.set(Calendar.MINUTE, 0);
calendar.set(Calendar.SECOND, 0);
Intent intent1 = new Intent(this, NotifyByBraodCast.class);
PendingIntent pendingIntent = PendingIntent.getBroadcast(
this, 0, intent1,
PendingIntent.FLAG_UPDATE_CURRENT);
AlarmManager am = (AlarmManager) this
.getSystemService(this.ALARM_SERVICE);
am.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(),
AlarmManager.INTERVAL_DAY, pendingIntent);
---------------------------------------------------------------------------------------------------

---------------------------------------------------------------------------------------------------
public class NotifyByBraodCast extends BroadcastReceiver {

NotificationManager nm;

@Override
public void onReceive(Context context, Intent intent) {
nm = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
CharSequence from = "Title";
CharSequence message = "Description!";
Intent notificationIntent = new Intent(context, splash.class);
PendingIntent contentIntent = PendingIntent.getActivity(context, 0, notificationIntent, 0);
Notification notification = new Notification(android.R.drawable.ic_media_play, "Let's Play!", System.currentTimeMillis());
notification.setLatestEventInfo(context, from, message, contentIntent);
notification.flags = Notification.DEFAULT_LIGHTS | Notification.FLAG_AUTO_CANCEL;
nm.notify(1, notification);
}
}
