Editor

This form field is a rich text editor, with formatting and an optional toolbar.

Class: Code16\Sharp\Form\Fields\SharpFormEditorField

Configuration

setHeight

Set the textarea height, in pixels.
If $maxHeight is set, the field will auto-grow until:

• the indicated height in pixels
• on infinitely if set to 0

showToolbar

hideToolbar

Show or hide the toolbar (shown by default).

setToolbar

Override the default toolbar, providing an array built with SharpFormEditorField's constants:

const B = 'bold';
const I = 'italic';
const HIGHLIGHT = 'highlight';
const UL = 'unordered-list';
const OL = 'ordered-list';
const SEPARATOR = ''|'';
const A = 'link';
const H1 = 'heading-1';
const H2 = 'heading-2';
const H3 = 'heading-3';
const TABLE = 'table';
const IFRAME = 'iframe';
const RAW_HTML = 'html';
const UNDO = 'undo';
const REDO = 'redo';
const CODE = 'code';
const QUOTE = 'blockquote';
const HR = 'horizontal-rule';

Example:

SharpFormEditorField::make("description")
    ->setToolbar([
        SharpFormEditorField::B, 
        SharpFormEditorField::I,
        SharpFormEditorField::SEPARATOR,
        SharpFormEditorField::A,
     ]);

setRenderContentAsMarkdown

If true the front will send the content as markdown to the back, for storage. Default is false.

setWithoutParagraphs

If true the editor won’t create <p>, but <br>. This is useful on some specific cases (everytime inline HTML is needed, maybe for a title or a legend). Default is false.

setMaxLength

Set an informative max character count. Will enforce showCharacterCount(true).

setMaxLengthUnlimited

Unset the max character count.

showCharacterCount

Display a character count in the status bar. Default is false.

Embed images and files in content

The Editor field can embed images or regular files. To use this feature, you must first allow the field to handle uploads:

allowUploads

This method allows the user to upload files and images in the editor:

$formFields->addField(
    SharpFormEditorField::make('bio')
        ->allowUploads(
            SharpFormEditorEmbedUpload::make()
                ->setStorageBasePath('posts/embeds')
                ->setStorageDisk('local')
        )
);

The SharpFormEditorEmbedUpload can be configured with the same API as the SharpFormUploadField: setMaxFileSize(), setImageOnly(), setAllowedExtensions(), ... (see full documentation)

A note on setImageTransformable

As for a regular upload field, you can allow the user to crop or rotate the visual, after the upload.
With $transformKeepOriginal set to true, the original file will remain unchanged, meaning the transformations will be stored directly in the <x-sharp-image/> tag. For instance:

{{-- (attribute JSON formatted for readability) --}}
<x-sharp-image 
    file='{
      "name":"image.jpg",
      "path": "data/Posts/1/image.jpg",
      "disk": "local",
      "filters": { "crop": { "x":0, "y":0, "width":.5, "height":.5 } } }
    '>
</x-sharp-image>

Then at render Sharp will take care of that for the thumbnail (see Display embedded files in the public site below).

Store images and files

Sharp takes care of copying the file at the right place (after image transformation, if wanted), based on the configuration.

When inserting a file, the following tag is added in field text value:

{{-- (attribute JSON formatted for readability) --}}
<x-sharp-file 
    file='{
      "name": "doc.pdf",
      "path": "data/Posts/1/doc.pdf",
      "disk": "local"
    '>
</x-sharp-file>

In case of an image the inserted tag is:

{{-- (attribute JSON formatted for readability) --}}
<x-sharp-image
    file='{
      "name":"image.jpg",
      "path": "data/Posts/1/image.jpg",
      "disk": "local",
    '>
</x-sharp-image>

Display embedded files / images in the public site

You may need to display those embedded files in the public website. The idea here is to display embedded images as thumbnails, and other files as you need. Sharp provides a component for that:

<x-sharp-content>
    {!! $html !!}
</x-sharp-content>

To handle image thumbnails, you can pass the following props:

<x-sharp-content
    :image-thumbnail-width="600"
    :image-thumbnail-height="400"
>
    {!! $html !!}
</x-sharp-content>

WARNING

<x-sharp-content> must have the editor content as direct child.

  <x-sharp-content>
-    <div>{!! $html !!}</div> {{-- this will not work --}}
+    {!! $html !!}
  </x-sharp-content>

Advanced usages

To add custom attributes to <x-sharp-image> component you can use the following syntax:

<x-sharp-content>
    <x-sharp-content::attributes
        component="sharp-image"
        class="my-image h-auto"
        :width="600"
    />
    {!! $html !!}
</x-sharp-content>

Customize views

You can extend <x-sharp-file> and <x-sharp-image> components by publishing them:

php artisan vendor:publish --tag=sharp-views

Here are the parameters passed to the components:

• $fileModel which is a SharpUploadModel instance (see the documentation); if you want to inject here your own SharpUploadModel implementation, you can do it by typing the full class path in the sharp.uploads.model_class config key.
• $width, $height, $filters: whatever you passed as attribute

Handle markdown

The <x-sharp-content> component does not render markdown, you will have to use your own <x-markdown> component or helper function. To make <x-sharp-*> elements working you must enable HTML in your parser (e.g. pass ['html_input' => 'allow'] to league/commonmark)

Example:

• Blade view file with <x-markdown> usage
• Markdown component using league/commonmark

WARNING

cebe/markdown is not compatible with sharp components

Custom embeds

This feature allows to embed any structured data in the content. A common use case is to embed a reference to another instance, like for example: in a blog post, you want to insert a reference to another post, that would be rendered as a “read also” block / link in the public section.

In practice, the Editor field can allow custom embeds, which defines how the data is stored in the field (as HTML attributes), and how it is edited in the UI, via a full-featured form.

allowEmbeds

This method expects an array of embeds that could be inserted in the content, declared as full class names. An embed class must extend Code16\Sharp\Form\Fields\Embeds\SharpFormEditorEmbed.

The documentation on how to write an Embed class is available here.

Formatter

• toFront: expects a string; will extract embedded files for the front.
• fromFront: returns a string, handle files (format, transformation, copy).
