Question

我有一个类别，我需要创建一个子类别。
当我尝试创建子类别时，我有一个名为category Name的字段，该字段应预先加载我想要创建子类别的类别名称。

我怎样才能实现这一目标..

我的控制器

public function actionCreate($id)
{
    $model=new SubCategory;
    $mode = Category::model()->findAll();
    $mode_1=$this->loadModel1($id);






    // Uncomment the following line if AJAX validation is needed
    // $this->performAjaxValidation($model);

    if(isset($_POST['SubCategory']))

    {
        $model->attributes=$_POST['SubCategory'];

        if($model->save())
            $this->redirect(array('create','id'=>$model->id));
    }

    $this->render('create',array(
        'model'=>$model,
    ));
}

表格

    <?php
/* @var $this SubCategoryController */
/* @var $model SubCategory */
/* @var $form CActiveForm */
?>

<div class="form">

<?php $form=$this->beginWidget('CActiveForm', array(
    'id'=>'sub-category-form',
    // Please note: When you enable ajax validation, make sure the corresponding
    // controller action is handling ajax validation correctly.
    // There is a call to performAjaxValidation() commented in generated controller code.
    // See class documentation of CActiveForm for details on this.
    'enableAjaxValidation'=>false,
)); ?>
<?php 
    $category_id = $_GET['id'];
    $category = Category::model()->findByAttributes(array('id' => $category_id));

    // echo '<pre>';print_r($category);'</pre>';
 ?>
    <p class="note">Fields with <span class="required">*</span> are required.</p>

    <?php echo $form->errorSummary($model); ?>
    <div class="row">
        <?php echo $form->labelEx($model,'category_id'); ?>
        <?php echo $form->textField($model,'category_id',
        array('class'=>'form-control','style'=>'width:300px;')); ?>

我可以看到类型模型$category被加载到表单中。

$category = Category::model()->findByAttributes(array('id' => $category_id));

如果id表中的category是主键，那么我建议，为了简单起见：

$category = Category::model()->findByPk($category_id);

现在我猜你可能想要在textField中禁用它。

因此，请在表单中使用textField() CActiveForm，例如：

$form->textField($category, 'name', array('disabled' => 'disabled'));

textField docs

注意：第二个参数必须是属性名称，我假设为name。

此外，我在actionCreate()中未看到使用以下两行。我的意思是，变量$mode和$mode_1不会在该操作中的任何位置使用。

$mode = Category::model()->findAll();
$mode_1=$this->loadModel1($id);
