Configure ModelSearch

how to configure the ModelSearch so that the index only shows the records that are made during the day?

The provider for a grid accepts a criteria. You need to modify it adding extra “where”.

I am trying this way but I get error Invalid argument supplied for foreach()

$startdate = date('Y-m-d', mktime(0, 0, 0, date('d'), 1, date('Y')));
$dateend = date('Y-m-d', mktime(0, 0, 0, date('d') + 1, 1, date('Y')));

$query = Pagos::find()->where('>=', 'fecha', '$startdate')->andwhere('<', 'fecha', '$dateend ');

I save the dates on the form like a this

<?= $form->field($model, 'fecha')->textInput(['value'=>date("Y-m-d H-i-s"), 'readonly'=> true] )?>

where() requires an array as Paramter. You provided 3 Strings instead.
Here a better approach:

$dateTime = new \DateTime();
$dateFormat = 'Y-m-d';
$from = $dateTime->format($dateFormat);
$till = $dateTime->modify('+1 day')->format($dateFormat);

$results = Pagos::find()->where([
	'between','fecha',$from ,$till
])->all();

Thank you
Remove ->all() at the end of $query
and it worked

$dateTime = new \DateTime();
$dateFormat = 'Y-m-d';
$from = $dateTime->format($dateFormat);
$till = $dateTime->modify('+1 day')->format($dateFormat);

$results = Pagos::find()->where([
	'between','fecha',$from ,$till
]);
