Laravel Nova - How to display partial textarea text on index

Question

Is there a way to display the first 25 chars of a Laravel\Nova\Fields\Textarea on the index of a Resource?

Answer 1

Just to expand on the answers above, here's the function I'm using that only uses the ellipsis when it cuts something off:

Text::make('Description')->rules('max:255')->displayUsing(function ($text) {
    if (strlen($text) > 30) {
        return substr($text, 0, 30) . '...';
    }
    return $text;
})

I would suggest using return Str::limit($text, 30); instead of the if. – Burgener

The comment from @Burgener about using the Laravel Str helper is correct, it saves using that entire if block. – Kulturkampf

It could be even shorter with arrow functions: Text::make('Description', 'name')->displayUsing(fn($id) => Str::limit($id, 20))->onlyOnIndex() – Hypogeum

Answer 2

We had the same problem and we solved it like this

Text::make('Text *', 'text')
            ->rules('required')
            ->hideFromIndex(),

Text::make('Text','text')
    ->displayUsing(function($id) {
        $part = strip_tags(substr($id, 0, 25));
        return $part . " ...";
    })->onlyOnIndex(),

hope this helps.

Yes, it is possible.

Starting from Nova v2, you can add ->showOnIndex(true) to the Textarea field, and then use the ->displayUsing() to extract a part of your text.

    Textarea::make('Description')
        ->showOnIndex(true)
        ->displayUsing(function($description) {
            return strip_tags(substr($description, 0, 50));
        })

Answer 4

I have created a nova package called ellipsis-textarea for fun, which you can use.

Install - composer require saumini/ellipsis-textarea

Usage -

use Saumini\EllipsisTextarea\EllipsisTextarea;

public function fields(Request $request)
{
    return [
        EllipsisTextarea::make('Copy')
          ->displayLength(25),
    ];
}

Here are two different ways I ended up accomplishing this without adding additional composer requirements using Macolson and ndee's answers:

use Illuminate\Support\Str;
use Laravel\Nova\Fields\Text;
use Laravel\Nova\Fields\BelongsTo;

 public function fields(Request $request)
    {
        return [
            ID::make(__('ID'), 'id')->sortable(),

            Text::make('Label')
                ->sortable()
                ->rules('required', 'max:255')
                ->displayUsing(function($text) {
                    return Str::limit($text, 30);}),

            BelongsTo::make('Survey Field', 'field', \App\Nova\SurveyField::class)
                // ->hideFromIndex()
                ->rules('required')
                ->displayUsing(function($object) {
                    $text = $object->title;
                    return Str::limit($text, 30);}),
        ];
    }
