yii2 form表单

1、命名空间引用 use yii\helpers\Html; use yii\widgets\ActiveForm; 2、form表单的开始和结束

• <?php $form = ActiveForm::begin([ 'action' =>'./admin.php?c=goods&a=add', 'method' => 'post', ])?>
• <?php ActiveForm::end();?>

3、设置显示式样 $form = ActiveForm::begin([ 'action' =>'./admin.php?c=goods&a=add', 'method' => 'get', 'fieldConfig' => [ 'template' => "<td{label}</td><td>{input}{error}</td>", ], ]) 4、汇总

• 文本框:textInput();
• 密码框:passwordInput();
• 单选框:radio(),radioList();
• 复选框:checkbox(),checkboxList();
• 下拉框:dropDownList();
• 隐藏域:hiddenInput();
• 文本域:textarea(['rows'=>3]);
• 文件上传:fileInput();
• 提交按钮:submitButton();
• 重置按钮:resetButtun();

下拉框例子： <?= $form->field($model,'goods_name')->dropDownList(['1'=>'请选择'],['style'=>'width:131px'])->label('商品分类'); 懒人程序引用：

<?php
$form = ActiveForm::begin([
    'action' => ['test/getpost'],
    'method'=>'post',
    ]); ?>
 
<? echo $form->field($model, 'username')->textInput(['maxlength' => 20]) ?>
<? echo $form->field($model, 'password')->passwordInput(['maxlength' => 20]) ?>
<? echo $form->field($model, 'sex')->radioList(['1'=>'男','0'=>'女']) ?>
<? echo $form->field($model, 'edu')->dropDownList(['1'=>'大学','2'=>'高中','3'=>'初中'],
                                              ['prompt'=>'请选择','style'=>'width:120px']) ?>
<? echo $form->field($model, 'file')->fileInput() ?>
<? echo $form->field($model, 'hobby')->checkboxList(['0'=>'篮球','1'=>'足球','2'=>'羽毛球','3'=>'乒乓球']) ?>
<? echo $form->field($model, 'info')->textarea(['rows'=>3]) ?>
 
<? echo $form->field($model, 'userid')->hiddenInput(['value'=>3]) ?>
 
<? echo Html::submitButton('提交', ['class'=>'btn btn-primary','name' =>'submit-button']) ?>   
<? echo Html::resetButton('重置', ['class'=>'btn btn-primary','name' =>'submit-button']) ?>
<?php ActiveForm::end(); ?>
