Input Counter

Adds configurable characters counter for text fields and RichEditors.

The counter supports a "min/max" range, as well as an "optimal" range. The counter background will turn yellow outside the optimal range, and red outside the min/max range.

For text fields, configuration is done using the attributes array. For RichEditors, use the editorOptions array (only available since October 3.6).

Available properties

• data-counter / counterEnabled (required)
• data-min-length / counterMinLength
• data-max-length / counterMaxLenght
• data-optimal-min-length / counterOptimalMinLength
• data-optimal-max-length / counterOptimalMaxLength

Example usage

From yaml

fields:
    # ...

    my_text_field:
        label: My Field
        type: text
        attributes:
            data-counter: true
            data-max-length: 50

    my_rich_editor:
        label: My RichEditor
        type: richeditor
        editorOptions:
            counterEnabled: true
            counterMaxLength: 200

    # ...

From a plugin

public function boot()
{
    Event::listen('backend.form.extendFieldsBefore', function (Backend\Widgets\Form $form) {
        $form->tabs['fields']['viewBag[meta_title]'] += [
            'attributes' => [
                'data-counter',
                'data-optimal-min-length' => 50,
                'data-optimal-max-length' => 60,
            ]
        ];
    }
}
