Critical Rules (Read from guidelines)

关键规则（请从指南中读取）

Before starting, you MUST read and follow these rules from

.guidelines/fields-development.md

Fields have TWO parts: PHP class (
```
app/MoonShine/Fields/
```
) + Blade view (
```
resources/views/admin/fields/
```
)
Fluent methods MUST return
static
- For method chaining
resolveOnApply()
MUST return the model - Always
```
return $item
```
at the end
Use
resolveOnAfterApply()
for relationships - Parent model needs ID first
viewData()
is for ADDITIONAL data ONLY - Don't pass
```
value
```
,
```
attributes
```
,
```
label
```
,
```
column
```
,
```
errors
```
(they're automatic!)

System data is ALWAYS available -

value

attributes

label

column

errors

come from

systemViewData()

ALWAYS add
{{ $attributes }}
to root element - Enables field customization from PHP
Handle multiple fields on one page - Use
```
uniqid()
```
for unique IDs, pass config to Alpine
assets()
method MUST be
protected
- NOT public
Use
toValue()
for raw values - In methods that need raw data
Use
toFormattedValue()
in
resolvePreview()
- For formatted display values
NEVER call
resolveValue()
manually - It's for internal rendering logic
Move logic to
prepareBeforeRender()
- NEVER write
```
@php
```
blocks in Blade views

开始开发前，你必须阅读并遵守

.guidelines/fields-development.md

中的以下规则：

字段由两部分组成：PHP类（
```
app/MoonShine/Fields/
```
） + Blade视图（
```
resources/views/admin/fields/
```
）
流式方法必须返回
static
以便支持方法链式调用
resolveOnApply()
必须返回模型请始终在方法末尾执行
```
return $item
```
关联关系请使用
resolveOnAfterApply()
处理因为父模型需要先获取ID
viewData()
仅用于传递额外数据不要传递
```
value
```
、
```
attributes
```
、
```
label
```
、
```
column
```
、
```
errors
```
（这些会自动注入！）

系统数据始终可用

value

、

attributes

、

label

、

column

、

errors

来自

systemViewData()

请始终给根元素添加
{{ $attributes }}
支持从PHP端自定义字段属性
处理单页多个字段的场景 使用
```
uniqid()
```
生成唯一ID，将配置传递给Alpine
assets()
方法必须声明为
protected
不能是public
获取原始值请使用
toValue()
在需要原始数据的方法中使用
在
resolvePreview()
中使用
toFormattedValue()
用于展示格式化后的显示值
永远不要手动调用
resolveValue()
它是供内部渲染逻辑使用的
将逻辑移到
prepareBeforeRender()
中永远不要在Blade视图中编写
```
@php
```

Understanding Field Contexts

字段上下文说明

Fields work in two main contexts:

字段主要在两种上下文下工作：

FormBuilder (Default Mode)

FormBuilder（默认模式）

Interactive inputs where users enter data. The field renders as

<input>

<select>

<textarea>

, etc.

供用户输入数据的交互输入框，字段会渲染为

<input>

、

<select>

、

<textarea>

等元素。

TableBuilder (Preview Mode)

TableBuilder（预览模式）

Read-only display in tables. The field shows formatted values, badges, images, etc.

The field automatically switches modes based on context. You control each mode's display via methods:

```
resolveValue()
```
- What appears in form inputs
```
resolvePreview()
```
- What appears in tables

表格中的只读展示形式，字段会显示格式化值、徽章、图片等内容。

字段会根据上下文自动切换模式，你可以通过以下方法控制每种模式的展示内容：

```
resolveValue()
```
- 表单输入框中展示的内容
```
resolvePreview()
```
- 表格中展示的内容

Your Task

你的任务

When creating custom fields:

Read the guidelines: Open and study
```
.guidelines/fields-development.md
```
Understand the request: What kind of field does the user need?
Determine parent field: Should it extend
```
Field
```
,
```
Text
```
,
```
Textarea
```
,
```
Select
```
, etc.?
Plan field structure:
- What properties does it need?
- What fluent methods should it have?
- What data goes to the view?
Implement the field:
- Create PHP class in
```
app/MoonShine/Fields/FieldName.php
```
- Create Blade view in
```
resources/views/admin/fields/field-name.blade.php
```
- Implement required methods
- Add assets if needed (CSS/JS)

创建自定义字段时：

阅读指南：打开并学习
```
.guidelines/fields-development.md
```
理解需求：用户需要什么类型的字段？
确定父类字段：应该继承
```
Field
```
、
```
Text
```
、
```
Textarea
```
、
```
Select
```
等哪个类？
规划字段结构：
- 需要哪些属性？
- 应该提供哪些流式方法？
- 需要传递哪些数据到视图？
实现字段：
- 在
```
app/MoonShine/Fields/FieldName.php
```
  路径下创建PHP类
- 在
```
resources/views/admin/fields/field-name.blade.php
```
  路径下创建Blade视图
- 实现所需方法
- 按需添加资源（CSS/JS）

Essential Methods

核心方法

viewData()
- Pass ADDITIONAL data to Blade view:

php

protected function viewData(): array
{
    return [
        // Don't pass 'value' - it's AUTOMATICALLY available!
        // Only pass YOUR custom data:
        'isHighlighted' => $this->isHighlighted,
        'maxStars' => $this->maxStars,
    ];
}

resolveValue()
- Get value for form input:

php

protected function resolveValue(): mixed
{
    return $this->toValue();
}

resolvePreview()
- Display in tables:

php

protected function resolvePreview(): Renderable|string
{
    return (string) $this->toFormattedValue();
}

resolveOnApply()
- Save to database:

php

protected function resolveOnApply(): ?Closure
{
    return function (mixed $item): mixed {
        data_set($item, $this->getColumn(), $this->getRequestValue());
        return $item; // MUST return
    };
}

prepareBeforeRender()
- Process logic BEFORE rendering:

php

protected function prepareBeforeRender(): void
{
    parent::prepareBeforeRender();
    // Add attributes, prepare data here
}

viewData()
- 向Blade视图传递额外数据：

php

protected function viewData(): array
{
    return [
        // Don't pass 'value' - it's AUTOMATICALLY available!
        // Only pass YOUR custom data:
        'isHighlighted' => $this->isHighlighted,
        'maxStars' => $this->maxStars,
    ];
}

resolveValue()
- 获取表单输入使用的值：

php

protected function resolveValue(): mixed
{
    return $this->toValue();
}

resolvePreview()
- 表格中的展示内容：

php

protected function resolvePreview(): Renderable|string
{
    return (string) $this->toFormattedValue();
}

resolveOnApply()
- 保存数据到数据库：

php

protected function resolveOnApply(): ?Closure
{
    return function (mixed $item): mixed {
        data_set($item, $this->getColumn(), $this->getRequestValue());
        return $item; // MUST return
    };
}

prepareBeforeRender()
- 渲染前的逻辑处理：

php

protected function prepareBeforeRender(): void
{
    parent::prepareBeforeRender();
    // Add attributes, prepare data here
}
