how to shorten long text in yii2 admin in gridview?

Answer 1

All $dataproperties are stored in, the function mb_substrcuts the string to the required number of characters, if the length of the source text is less than the specified one, then we output it without changes, otherwise we print the shortened string.
Substitute myattributeyour attribute.

[
    'attribute' => 'myattribute',
    'value' => function($data) {
        $charsCount = 100;
        $croppedText = mb_substr($data->text, 0, $charsCount);
        return mb_strlen($data->text) > 100 ?  $croppedText : $data->text;
    }
],
