Php Magento-试图创建一个编辑管理表单，但它在表单中提供空白输入字段

我正在使用Magento 1.9.0.1

我正在开发一个自定义Magento扩展，到目前为止，我已经在管理面板中创建了一些自定义页面。在其中一个表中，我添加了一个网格表，它从自定义MySQL表中获取结果

让我向您展示此页面的屏幕截图：

问题就出在这里，当编辑表单打开时，表单中的输入字段是空的。它们不能是空的。。。正如您所知，这是一个编辑表单，必须有一个数据进行编辑

以下是一个屏幕截图：

正如您所看到的，字段是空的。。。这就是问题所在

让我向您展示我认为对解决问题很重要的所有代码

我认为您在控制器的editAction（）中做了更多的工作

 public function getRowUrl($row)
{
    return $this->getUrl('*/*/edit', array('id'=>$row->getId()));
}

在这里，它返回行的id。您需要使用此“id”

$id = $this->getRequest()->getParam('id');

从模型中获取数据

你真正需要做的事情是在你的生活中

/app/code/community/VivasIndustries/SmsNotification/Block/Adminhtml/Sms/Status/Edit/Form.php

在文件末尾放置此代码

$id = Mage::app()->getRequest()->getParam('id');
$model= Mage::getModel('smsnotification/smsnotification')->load($id);
  $form->setValues($model->getData());

试试这个。希望这会有所帮助。
您应该在Grid.php上的每个字段中添加一个属性“index”

在form.php上，您可以使用以下索引创建a字段：
例如：

Grid.php：

$this->addColumn('id_provider', array(
        'header' => 'Provider',
        'align' => 'left',
        **'index' => 'id_provider',**


    ));

在form.php上：

$fieldset->addField(**'id_provider'**, 'text', array(
        'label' => 'Provider',
        'name' => 'provider',
        'required' => true,

    ));

我不明白。我必须在哪个文件中从什么编辑到什么？提前谢谢！通过这个链接。在这个类“Excellence\u Form\u Block\u Adminhtml\u Form\u Edit\u Tab\u Form”中，检查受保护的函数_prepareForm（）{$Form=new Varien\u Data\u Form（）；$this->setForm（$Form）；我认为这个setForm（）做的诀窍。分享你将得到的。请给我一个详细的编辑我的代码的方式，你认为它必须工作。我不明白你要我做什么。提前谢谢！不要误会我bt尝试更多的frm你方我想让你得到$id在_perpareForm（）函数并在您的模型中使用它，即在“smsnotification/smsnotification”的情况下，并在表单中设置值。请尝试以下代码$id=Mage:：app（）->getRequest（）->getParam（'id'））；//将此id加载到模型$model=Mage:：getModel（'smsnotification/smsnotification'）->load（$id）；$form->setValues（$model->getData（））；将其置于$this->setForm（$form）之前；希望这能起作用。你能用你最后的评论意见编辑答案吗？因为评论中的描述太混乱了。当你在评论中发布代码时，我无法获得正确的代码。我将非常感谢！
