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(),

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.

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());

nm.notify(1, notification);
}
}

raw query plan to get woocommerce order by specific user

First go to postmeta table with user id then you will get order id as post id then with those post id go to order_itemmeta table to get order details in row then with that order_itemmeta table you will get order_item_id with meta value, this meta value is your product id you can now get that product info by that product id in posts table now make a join query to get all those thing in one table :) Good luck!
