The supported components for forms and fields in Yii2 are ActiveForm and ActiveField.
To generate a login box with a common format such as label, input, and error prompt, you can write the following code:
<?php $form = ActiveForm::begin([
'id' => 'login-form',
'options' => ['class' => 'form-horizontal'],
'fieldConfig' => [
'template' => "{label}\n<div class=\"col-lg-3\">{input}</div>\n<div class=\"col-lg-8\">{error}</div>",
'labelOptions' => ['class' => 'col-lg-1 control-label'],
],
]); ?>
<?= $form->field($model, 'username') ?>
<?= $form->field($model, 'password')->passwordInput()
?>
The above code generates two form input boxes (inputs) with default label names (such as Username, Password).
If you want to change the label and style of the input box, there are two ways, one is through the labelOptions parameter:
Copy the codeThe code is as follows:
<?= $form->field($model, 'username',['labelOptions' => ['label' => 'Nick name','class' => 'your own class']]) ?>
Another more object-oriented method is:
Copy the codeThe code is as follows:
<?= $form->field($model, 'username')->textInput()->hint('Please enter your nick name instead of email')->label('Nick name') ?>
