File

Pair framework: File

Pair\Html\FormControls\File renders file upload inputs and provides MIME-category helpers.

Methods

• accept(string|array $mimeType): self
• acceptCategory(string $mimeCategory): self
• acceptCategories(array $mimeCategories): self
• capture(?string $cameraFacingMode = null): self
• mimeCategory(string $mimeType): ?string (static)
• render(): string

MIME categories

Built-in categories in File::MIME_TYPES:

• audio
• binary
• csv
• document
• image
• pdf
• presentation
• spreadsheet
• video
• zip

Behavior

• accept(...) is cumulative: multiple calls append entries separated by commas.
• acceptCategory(...) silently ignores unknown categories.
• capture(...) sets the capture attribute for mobile camera/source hints.
• mimeCategory(...) returns the first matching category for a MIME string or extension, otherwise null.

Examples

Allow images and PDFs:

$attachment = (new \Pair\Html\FormControls\File('attachment'))
    ->acceptCategory('image')
    ->acceptCategory('pdf')
    ->required();

Explicit MIME list + camera hint:

$avatar = (new \Pair\Html\FormControls\File('avatar'))
    ->accept(['image/png', 'image/jpeg'])
    ->capture('user');

Resolve category from MIME string:

$category = \Pair\Html\FormControls\File::mimeCategory('application/pdf');
// 'pdf'

Notes

The accept attribute helps UX but does not replace server-side upload validation.
