Using yii2 date range in active record

search between two dates in yii2

Correct way of date range check

$model = ModelName::find()->where(['between', 'date', "2015-06-21", "2015-06-27" ])
->all();

Using between

$query= Stockdistributelog::find();

$query->where(['center_ccid'=>$model->center_ccid]);

$query->andwhere(['between', 'date', date('Y-m-d',strtotime($model->date)),date('Y-m-d',strtotime($model->date_to)) ]);

$query->all();

$programs = Programs::find()->where(['>=', 'close_date', $today])->all();

Solutions for date picker does not work properly in dynamic forms

Date picker widget add in dynamic form of yii2.

Problem using your yii2 extension, especialy the bootstrap datepicker is not show up.
You should add datepicker manually for dynamically genereted instances:

Add code in register javascript

$(".dynamicform_wrapper2").on("afterInsert afterDelete", function(e, item) {

var VarItemsQuantity = $('.item2').length, VarCounter = 1;
for(VarCounter; VarCounter < VarItemsQuantity; VarCounter++) {
$('#dailyaccountbank-'+VarCounter+'-date').
parent().datepicker({"autoclose":true, "format":"d-m-yyyy", 'language':'ru',});
};

View form like this

<?php

use yii\helpers\Html;
use yii\widgets\ActiveForm;
use wbraganca\dynamicform\DynamicFormWidget;
use yii\helpers\ArrayHelper;
use dosamigos\datepicker\DatePicker;

/* @var $this yii\web\View */
/* @var $model backend\modules\master\models\Students */

$this->title = 'Daily Account From';
//$this->params['breadcrumbs'][] = ['label' => 'Daily', 'url' => ['index']];
$this->params['breadcrumbs'][] = $this->title;

?>

<?php

$script = <<< JS

$(".dynamicform_wrapper").on("afterInsert afterDelete", function(e, item) {

var VarItemsQuantity = $('.item').length, VarCounter = 1;
for(VarCounter; VarCounter < VarItemsQuantity; VarCounter++) {
$('#dailyaccountbank-'+VarCounter+'-date').
parent().datepicker({"autoclose":true, "format":"d-m-yyyy", 'language':'ru',});
};

});


JS;
$this->registerJs($script);
?>
