# FormFieldWrapper Component
A unified form field component that automatically provides hints, validation messages, and terminology tooltips based on field type.
## Features
-**Automatic hints** based on field type (speed, height, URL, email, etc.)
-**Built-in validation** display with error messages
-**Terminology tooltips** on labels (hover to see definitions)
-**Character counting** for textareas
-**50% less boilerplate** compared to manual field creation
-**Type-safe** with TypeScript
-**Consistent styling** across all forms
## Quick Start
### Before (Manual)
```tsx
<div className="space-y-2">
<Label htmlFor="website_url">Website URL</Label>
<Input
id="website_url"
type="url"
{...register('website_url')}
placeholder="https://..."
/>
<p className="text-xs text-muted-foreground">
Official website URL (must start with https:// or http://)
</p>
{errors.website_url && (
<p className="text-sm text-destructive">{errors.website_url.message}</p>
)}
</div>
```
### After (With FormFieldWrapper)
```tsx
<FormFieldWrapper
id="website_url"
label="Website URL"
fieldType="url"
error={errors.website_url?.message as string}
inputProps={{
...register('website_url'),
placeholder: "https://..."
}}
/>
```
## Basic Usage
```tsx
import { FormFieldWrapper } from '@/components/ui/form-field-wrapper';
import { useForm } from 'react-hook-form';
function MyForm() {
const { register, formState: { errors } } = useForm();
return (
<form>
{/* Basic text input with automatic hint */}
<FormFieldWrapper
id="email"
label="Email Address"
fieldType="email"
required
error={errors.email?.message as string}
inputProps={{
...register('email', { required: 'Email is required' }),
placeholder: "contact@example.com"
}}
/>
{/* Textarea with character count */}
<FormFieldWrapper
id="notes"
label="Notes for Reviewers"
fieldType="submission-notes"
optional
value={watch('notes')}
maxLength={1000}
error={errors.notes?.message as string}
textareaProps={{
...register('notes'),
placeholder: "Add context...",
rows: 3
}}
/>
</form>
);
}
```
## With Terminology Tooltips
```tsx
<FormFieldWrapper
id="inversions"
label="Inversions"
fieldType="inversions"
termKey="inversion" // Adds tooltip explaining what inversions are
error={errors.inversions?.message as string}
inputProps={{
...register('inversions'),
type: "number",
placeholder: "e.g. 7"
}}
/>
```
## Using Presets
```tsx
import { FormFieldWrapper, formFieldPresets } from '@/components/ui/form-field-wrapper';
<FormFieldWrapper
{...formFieldPresets.sourceUrl({})}
id="source_url"
error={errors.source_url?.message as string}
inputProps={{
...register('source_url'),
placeholder: "https://..."
}}
/>
```
## Available Field Types
- `url` - Website URLs with protocol hint
- `email` - Email addresses with format hint
- `phone` - Phone numbers with flexible format hint
- `slug` - URL slugs with character restrictions
- `height-requirement` - Height in cm with metric hint
- `age-requirement` - Age requirements
- `capacity` - Capacity per hour
- `duration` - Duration in seconds
- `speed` - Max speed (km/h)
- `height` - Max height (meters)
- `length` - Track length (meters)
- `inversions` - Number of inversions
- `g-force` - G-force values
- `source-url` - Reference URL for verification
- `submission-notes` - Notes for moderators (textarea with char count)
## Available Presets
```tsx
formFieldPresets.websiteUrl({})
formFieldPresets.email({})
formFieldPresets.phone({})
formFieldPresets.sourceUrl({})
formFieldPresets.submissionNotes({})
formFieldPresets.heightRequirement({})
formFieldPresets.capacity({})
formFieldPresets.duration({})
formFieldPresets.speed({})
formFieldPresets.height({})
formFieldPresets.length({})
formFieldPresets.inversions({})
formFieldPresets.gForce({})
```
## Custom Hints
Override automatic hints with custom text:
```tsx
<FormFieldWrapper
id="custom"
label="Custom Field"
fieldType="text"
hint="This is my custom hint that overrides any automatic hint"
inputProps={{...register('custom')}}
/>
```
## Hide Hints
```tsx
<FormFieldWrapper
id="no_hint"
label="Field Without Hint"
fieldType="url"
hideHint
inputProps={{...register('no_hint')}}
/>
```
## Migration Guide
To migrate existing fields:
1. **Identify the field structure** to replace
2. **Choose appropriate `fieldType`** from the list above
3. **Add `termKey`** if field relates to terminology
4. **Replace** the entire div block with `FormFieldWrapper`
Example migration:
```tsx
// BEFORE
<div className="space-y-2">
<Label htmlFor="max_speed_kmh">Max Speed (km/h)</Label>
<Input
id="max_speed_kmh"
type="number"
{...register('max_speed_kmh')}
placeholder="e.g. 193"
/>
<p className="text-xs text-muted-foreground">
Speed must be in km/h, between 0-500. Example: "193" for 193 km/h (120 mph)
</p>
{errors.max_speed_kmh && (
<p className="text-sm text-destructive">{errors.max_speed_kmh.message}</p>
)}
</div>
// AFTER
<FormFieldWrapper
id="max_speed_kmh"
label="Max Speed (km/h)"
fieldType="speed"
termKey="kilometers-per-hour"
error={errors.max_speed_kmh?.message as string}
inputProps={{
...register('max_speed_kmh'),
type: "number",
placeholder: "e.g. 193"
}}
/>
```
