Magento-試圖創建一個編輯管理表單，但是它在表單中給出了空白的輸入字段

Question

我正在使用Magento 1.9.0.1。

我正在開發自定義的Magento擴展程序，到目前為止，我已經在管理面板中創建了一些自定義頁面。 在其中之一中，我添加了一個網格表，該表從自定義MySQL表中獲取結果。

讓我向您顯示此頁面的屏幕截圖：

問題出在這里，當打開“編輯”表單時，其中的輸入字段為空。 它們一定不能為空...如您所知，這是“編輯”表單，並且必須有要編輯的數據！

這是屏幕截圖：

如您所見，這些字段為空...這就是問題所在...

讓我向您展示我認為對解決問題很重要的所有代碼。

        }

        return $this->getData('smsnotification');
    }
}

因此，請告訴我我在哪個文件中出錯，因此它向我顯示了空字段。

我該如何解決這個問題？

提前致謝！

Answer 1

我認為您還可以在控制器的editAction（）中做更多的事情，如您在grid.php文件中看到的以下代碼所示

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

在這里，它返回行的ID。 您需要使用此“ id”。

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

從模型中獲取數據

您需要做的實際事情是

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

在文件末尾放置此代碼

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

試試這個。希望這會有所幫助。

Answer 2

您應該在Grid.php的每個字段中添加一個屬性“索引”

在form.php上，您創建一個具有以下索引的字段：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,

    ));
