I trying to create a survey website, so I found some example that I want to test it and change it as I want, but the problem is when I choose the question type to be "Radio" OR "Checkbox" I get this error message:
Invalid argument supplied for foreach() (View: /Users/ANA/laravel/app/resources/views/survey/detail.blade.php)
I know now there is something wrong passing to foreach, but I don't know what!. It's my first time to use Laravel, that why I'm struggling to know what's going on.
And this is the highlighted code after the error message:
</div>
</div>
<?php elseif($question->question_type === 'radio'): ?>
<?php $__currentLoopData = $question->option_name; $__env->addLoop($__currentLoopData); foreach($__currentLoopData as $key=>$value): $__env->incrementLoopIndices(); $loop = $__env->getLastLoop(); ?>
<p style="margin:0px; padding:0px;">
<input type="radio" id="<?php echo e($key); ?>" />
<label for="<?php echo e($key); ?>"><?php echo e($value); ?></label>
</p>
<?php endforeach; $__env->popLoop(); $loop = $__env->getLastLoop(); ?>
<?php elseif($question->question_type === 'checkbox'): ?>
<?php $__currentLoopData = $question->option_name; $__env->addLoop($__currentLoopData); foreach($__currentLoopData as $key=>$value): $__env->incrementLoopIndices(); $loop = $__env->getLastLoop(); ?>
<p style="margin:0px; padding:0px;">
<input type="checkbox" id="<?php echo e($key); ?>" />
<label for="<?php echo e($key); ?>"><?php echo e($value); ?></label>
</p>
<?php endforeach; $__env->popLoop(); $loop = $__env->getLastLoop(); ?>
<?php endif; ?>
<?php echo Form::close(); ?>
This is the code detail.blade.php:
