Source Code https://github.com/yiisoft/yii2/blob/master/framework/widgets/MaskedInput.php

MaskedInput generates a masked text input.

MaskedInput is similar to yii\helpers\Html::textInput() except that an input mask will be used to force users to enter properly formatted data, such as phone numbers, social security numbers.

To use MaskedInput, you must set the $mask property. The following example shows how to use MaskedInput to collect phone numbers:

echo MaskedInput::widget([
    'name' => 'phone',
    'mask' => '999-999-9999',
]);

You can also use this widget in an yii\widgets\ActiveForm using the widget() method, for example like this:

<?= $form->field($model, 'from_date')->widget(\yii\widgets\MaskedInput::className(), [
    'mask' => '999-999-9999',
]) ?>

The masked text field is implemented based on the jQuery input masked plugin.

Property Details

$_hashVar protected property

The hashed variable to store the pluginOptions

protected string $_hashVar null
$aliases public property

Custom aliases to use. Should be configured as maskAlias => settings, where

  • maskAlias is a string containing a text to identify your mask alias definition (e.g. 'phone') and
  • settings is an array containing settings for the mask symbol, exactly similar to parameters as passed in $clientOptions.
public array $aliases null

public array $definitions null
$mask public property

The input mask (e.g. '99/99/9999' for date input). The following characters can be used in the mask and are predefined:
