我有这样ActiveForm的看法。如何在此视图中允许用户选择数量的子项（表单项），并向所有数量的子项提交相同的模型项。
<?php $form = ActiveForm::begin([]) ?>
<div class="child_card">
<?=$form->field($child, 'first_name', ['inputOptions' => ['placeholder' => 'Enter Your First Name']])?>
<?=$form->field($child, 'middle_name',
['inputOptions' => ['placeholder' => 'Enter Your Middle Name']])?>
<?=$form->field($child, 'last_name', ['inputOptions' => ['placeholder' => 'Enter Your Last Name']])?>
<br>
<?=$form->field($child, 'gender', [
'template' => '{label} <div class="field">{input}{error}{hint}</div>',
'inputOptions' => [
'placeholder' => 'Gender',
],
])->dropDownList([
'male' => 'Male',
'female' => 'Female',
], ['class' => 'ui dropdown selection', 'prompt' => 'Gender'])->label('Select your gender')?>
<?=$form->field($child, 'birthdate_month', [
'template' => '{label} <div class="field">{input}{error}{hint}</div>',
'inputOptions' => [
'placeholder' => 'Month',
],
])->dropDownList([
'January' => 'January',
'February' => 'February',
'March' => 'March',
'April' => 'April',
'May' => 'May',
'June' => 'June',
'July' => 'July',
'August' => 'August',
'September' => 'September',
'November' => 'November',
'December' => 'December',
], ['class' => 'ui dropdown selection', 'prompt' => 'Month'])->label('Birthdate')?>
<?=$form->field($child, 'birthdate_day', [
'template' => '{label} <div class="field">{input}{error}{hint}</div>',
'inputOptions' => [
'placeholder' => 'Day',
],
])->dropDownList([
'1' => '1',
'2' => '2',
'3' => '3',
'4' => '4',
'5' => '5',
'6' => '6',
'7' => '7',
'8' => '8',
'9' => '9',
'10' => '10',
'11' => '11',
'12' => '12',
'13' => '13',
'14' => '14',
'15' => '15',
'16' => '16',
'17' => '17',
'18' => '18',
'19' => '19',
'20' => '20',
'21' => '21',
'22' => '22',
'23' => '23',
'24' => '24',
'25' => '25',
'26' => '26',
'27' => '27',
'28' => '28',
'29' => '29',
'30' => '30',
'31' => '31',
], ['class' => 'ui dropdown selection', 'prompt' => 'Day'])->label(false)?>
<?=$form->field($child, 'birthdate_year', [
'template' => '{label} <div class="field">{input}{error}{hint}</div>',
'inputOptions' => [
'placeholder' => 'Year',
],
])->dropDownList([
'2016' => '2016',
'2015' => '2015',
'2014' => '2014',
'2013' => '2013',
'2012' => '2012',
'2011' => '2011',
'2010' => '2010',
'2009' => '2009',
'2008' => '2008',
'2007' => '2007',
'2006' => '2006',
'2005' => '2005',
'2004' => '2004',
'2003' => '2003',
'2002' => '2002',
'2001' => '2001',
'2000' => '2000',
'1999' => '1999',
'1998' => '1998',
'1997' => '1997',
'1996' => '1996',
'1995' => '1995',
], ['class' => 'ui dropdown selection', 'prompt' => 'Year'])->label(false)?>
<?=$form->field($child, 'country_of_birth',
['inputOptions' => ['placeholder' => "Enter Your Child's Country of Birth"]])
->label('Your Child’s Country of Birth:')?>
<?=$form->field($child, 'city_of_birth',
['inputOptions' => ['placeholder' => "Enter Your Child's City of Birth"]])
->label('Your Child’s City/Town of Birth:')?>
</div>
<?php ActiveForm::end(); ?>
答案是使用简单的for循环。
视图示例
<?php $form = ActiveForm::begin() ?>
<?php foreach ($children as $i => $child): ?> //there are multiple persons (children)
...
<?=$form->field($child, "[$i]birthdate_month", [...])->dropDownList([
'1' => 'January',
...
])?>
...
<?php endforeach; ?>
...
<?=Html::submitButton('Save', ['class' => 'ui primary button big'])?>
...
<?php ActiveForm::end(); ?>
并在控制器中使用
Person::loadMultiple($children, Yii::$app->request->post());
