Accessing Values

In Twig Templates

{# Display file name #}
{{ entry.attachment.name }}

{# Display file link #}
<a href="{{ entry.attachment.path }}">Download {{ entry.attachment.name }}</a>

{# Display image #}
{% if entry.image %}
    <img src="{{ entry.image.path }}" alt="{{ entry.image.name }}">
{% endif %}

{# Display image with manipulation #}
<img src="{{ entry.avatar.make().fit(200, 200).path() }}" alt="Avatar">

{# Check if file exists #}
{% if entry.document %}
    <p>Document attached: {{ entry.document.name }}</p>
{% endif %}

{# Get file properties #}
{{ entry.attachment.size }} bytes
{{ entry.attachment.extension }}
{{ entry.attachment.mime_type }}

In PHP

$entry = $model->find(1);

// Get file object
$file = $entry->attachment;

if ($file) {
    // Get file properties
    $name = $file->name;
    $path = $file->path();
    $size = $file->size;
    $extension = $file->extension;
    $mimeType = $file->mime_type;
    
    // Get file ID
    $fileId = $entry->attachment_id;
    
    // Image manipulation
    if ($file->isImage()) {
        $thumbnail = $file->make()->fit(150, 150)->path();
    }
}

Setting Values

In Forms

$form = $builder->make('example.module.test');
$form->on('saving', function(FormBuilder $builder) {
    $entry = $builder->getFormEntry();
    
    // Set file ID
    $entry->attachment = 5;
});

Direct Assignment

// Set by file ID
$entry->attachment_id = 10;
$entry->save();

// Or set by file object
$file = File::find(10);
$entry->attachment()->associate($file);
$entry->save();

Database Structure

The file field type stores the file relationship as:

• INTEGER - Foreign key to files_files.id

Validation

Required File

'attachment' => [
    'type'  => 'anomaly.field_type.file',
    'rules' => [
        'required'
    ]
]

File Must Exist

'document' => [
    'type'  => 'anomaly.field_type.file',
    'rules' => [
        'required',
        'exists:files_files,id'
    ]
]

Common Use Cases

User Avatar

'avatar' => [
    'type'   => 'anomaly.field_type.file',
    'config' => [
        'folders'    => ['avatars'],
        'extensions' => ['jpg', 'jpeg', 'png', 'gif'],
        'mode'       => 'compact'
    ]
]

PDF Document Upload

'contract' => [
    'type'   => 'anomaly.field_type.file',
    'config' => [
        'folders'    => ['contracts'],
        'extensions' => ['pdf']
    ],
    'rules' => [

Best Practices

1. Restrict Folders: Always limit uploads to specific folders for organization
2. Validate Extensions: Use extension restrictions for security
3. Image Optimization: Use image manipulation for thumbnails and responsive images
4. Clean Up: Implement cleanup for unused file records
5. Check Existence: Always check if file exists before accessing properties
6. Use Relationships: Leverage Eloquent relationships for easy access
7. Consider Storage: Monitor disk space for large file uploads
