Laravel blade “old input or default variable”?

Question

I want to show the old input in input value. If there isn\'t old input, than show other variable:

value=\"{{ old(\'salary_\' . $employee->id) or \'Default\' }         


        

Answer 1

You can use the code (for PHP 7):

{{ old('field_name') ?? $model->field_name ?? 'default' }}

For checkbox checked attribute use the code (if default value is false):

{{ (old() ? old('field_name', false) : $model->field_name ?? false) ? 'checked' : '' }}

Construction {{ $something or 'default'}} works only for variables
