Blade - check if variable is being passed from controller

I am passing a variable from the controller

$data = array(
    'title'  => 'my title',
    'name' => 'John'
);

return View::make('mypage'')->with('data', $data);

Can I test if the variable exists? As name is not in every page and throws an error.

@if $data['name'] {{  $data['name'] }} @endif

You can try something like:

@if( ! empty($data['name'))
    //
@endif

PS: please wrap your code in ~~~ to format code segments.

Or if you need to do it inside a div or HTML element, do a shorthand if else

<a href="" class="{{ ( ! empty($data['name'] ? 'nameset' : 'namenotset') }}">

Or you can simple use:

{{ $data['var'] or 'empty string' }}

If you want to check if the variable exists, use isset otherwise use empty if the variable will always be set and you want to determine if its value is falsey.

I used this in my case and it works perfect.

<i class="{{ ( ! empty($message->attachment) ? 'fa fa-paperclip' : '') }}"

@DIVISIONB - This will not work in all cases, for example, if i have an Carbon instance, and try to print this way, it will fail, because i can't call "format" on a null element

@USMAN -

@if(!empty($data['name']))
    //
@endif

You missed a closing square bracket
