推荐答案

要更改图像，您可以将其添加到模型中:

To change the image you can add this to your model:

public $attachOne = ['avatarImage'];

而且您不必在数据库中创建名为 avatarImage 的列，因为十月会自动将您的图像存储在另一个名为system_files"或类似的表中.因此，在您的 fields.yaml 中，您必须添加以下内容:

and you don't have to create a column in the database called avatarImage because October will automatically store your image in another table called 'system_files' or something like that. So in your fields.yaml you'll have to add this:

avatarImage:
     type: mediafinder
     mode: image
     label: My Avatar

然后，October 将在控制面板的设置控制器中创建一个 mediafinder 表单小部件，您可以对其进行更改.要在前端页面中显示图像，您必须在页面的 php 代码部分添加一些代码

Then October will create a mediafinder form widget in your settings controller in the control panel and you can change it. And to show the image in your frontend page you will have to add some code in the php code section of the page

$this['settings'] = //The Code to Get the Model;

您可以轻松地使用 getPath() 方法显示图像.

And easily you can display the image using getPath() method.

<img src="{{ settings.getPath() }}" />

如果上面的代码不起作用，您可以将其替换为:

If the above code didn't work you can replace it with:

<img src="{{ settings.getPath()|media" />

我认为第二个会正常工作，我有一段时间没有使用 october :D

I think the second one will work correctly, I didn't use october for a while :D
