I’ve got a object which has the method hasATest that returns a boolean and depending on the value I want a button to be enabled or disabled so I thought of doing something like this:
<button class="btn btn-xs btn-detail btn-activate" name="question_id" value="{{$question->id}}" id="activate{{$question->id}}"
"{{ $question->hasATest() ? disabled : }}"> Activate
</button>
But I don’t know what to do about the else. If I remove the :, an error occurs:
"unexpected =" ...
Plus it’s not like there’s the opposite for disabled.
The ternary operator needs an else as you already discovered, you could try some statements like null or in this case "" to return empty values on the else.
{{ ($question->hasATest()) ? "disabled" : "" }}
Answer：
Just use an empty string for the else part.
<button class="btn btn-xs btn-detail btn-activate" name="question_id" value="{{$question->id}}" id="activate{{$question->id}}"
{{ $question->hasATest() ? 'disabled' : '' }}> Activate
</button>
I think you could also use an @if for it instead of a ternary.
<button class="btn btn-xs btn-detail btn-activate" name="question_id" value="{{$question->id}}" id="activate{{$question->id}}"
@if($question->hasATest()) disabled @endif> Activate
</button>
Answer：
You have problem in this line:
"{{ $question->hasATest() ? disabled : }}"
Here is the solution:
{{ ($question->hasATest()) ? disabled : 'enable' }}
Answer：
For those who has to check over the Non-boolean variable is there or not
e.g. $question->test returns test name (string) then you can use isset
<td>
{{ isset($question->test) ? $question->test : __('question.no_test') }}
</td>
