magento2 后台添加产品自定义字段,保存不到数据库中

[yugr]

后台产品添加时自定义了两个字段,是可以显示的,但是在保存产品后,发现新增的字段没有保存
如下图:

我的product_form.xml 代码如下:

<?xml version="1.0" encoding="UTF-8"?>

  <fieldset name="manage_note">
     <argument name="data" xsi:type="array">        
         <item name="config" xsi:type="array">
             <item name="label" xsi:type="string" translate="true">Group purchase</item>
             <item name="dataScope" xsi:type="string"/>
             <item name="sortOrder" xsi:type="number">0</item>
             <item name="collapsible" xsi:type="boolean">true</item>

     <field name="Collage_number">

         </argument>
        
     </field>       
 </fieldset>

请问我该如何解决呢?

现新增的字段没有保存
如下图:

这只是界面上增加了，你还需要了解一下Magento的EVA

Add EAV Attribute

如果感兴趣，请麻烦翻译后发到本站上，谢谢.

创建自定义字段应该是
xxx/xxx/Setup/InstallData 中

namespace xxx\xxx\Setup;

use Magento\Eav\Setup\EavSetup;
use Magento\Eav\Setup\EavSetupFactory;
use Magento\Framework\Setup\InstallDataInterface;
use Magento\Framework\Setup\ModuleContextInterface;
use Magento\Framework\Setup\ModuleDataSetupInterface;

class InstallData implements InstallDataInterface
{
private $eavSetupFactory;
public function __construct(
EavSetupFactory $eavSetupFactory
)
{
$this->eavSetupFactory = $eavSetupFactory;
}

public function install(ModuleDataSetupInterface $setup, ModuleContextInterface $context)
{
    $eavSetup = $this->eavSetupFactory->create(['setup' => $setup]);
    $eavSetup->addAttribute(
      \Magento\Catalog\Model\Product::ENTITY,
      "collage_number",
      [
      'group' => "Group purchase",
      'label' => "Number of group buying",
      'global' => \Magento\Catalog\Model\ResourceModel\Eav\Attribute::SCOPE_STORE,
      'visible' => true,
      'visible_on_front' => true,
      "used_in_product_listing" => true,
      "input" => "input",
      "type" => "int",
      ]
  );
    $eavSetup->addAttribute(
      \Magento\Catalog\Model\Product::ENTITY,
      "collage_price",
      [
      'group' => "Group purchase",
      'label' => "Group purchase price",
      'is_html_allowed_on_front' => true,
      'global' => \Magento\Catalog\Model\ResourceModel\Eav\Attribute::SCOPE_STORE,
      'visible' => true,
      'required' => true,
      'visible_on_front' => true,
      "used_in_product_listing" => true,
      "input" => "input",
      "type" => "decimal",
      ]
  );
}

}

然后在运行 php bin/magento setup:upgrade 命令,就可以在后台看到新加的两个字段了,这时候就可以保存到数据库了,但是样式是没有的,采用的是默认样式,至于怎么更改样式我还没搞清楚
