Ternary operator sort syntax can't work in laravel blade

Question

laravel blade ternary operator

 {{ isset($name) ? $name : 'Default' }}

we can write short form

{{ $name or 'Default' }}

but it returns the Boolean value when implement like:

 {{$videos->count() or 'no video' }} //if count return 1 always,

but this code

  {{ $videos->count()}} // return 4

how to implement this by short form in blade ternary operator

You want to show the count if it's > 0. Else you want to show the text.

Your count() is always not null (0 or higher). So what you want to do is this:

{{$videos->count() > 0 ? $vides->count() : 'no video'}}

This can be made shorter by using PHP 7 operators. Please see my answer. – Josh Bolton Mar 23 '17 at 12:16
@JoshBolton I don't think so, because `count()` is never null. – schellingerht Mar 23 '17 at 12:18

Seen as you are using PHP 7.1 you can use the new Null Coalescing Operator. All PHP 7's new features can be found in the docs: http://php.net/manual/en/migration70.new-features.php

Your code would then look like this:

{{$videos->count() ?? 'no video' }}

There is a detailed description of the operator in the docs:

The null coalescing operator (??) has been added as syntactic sugar for the common case of needing to use a ternary in conjunction with isset(). It returns its first operand if it exists and is not NULL; otherwise it returns its second operand.

`count()` is 0 or higher, never null. – schellingerht Mar 23 '17 at 12:26 — schellingerht, Mar 23 '17 at 12:26
