How to echo a default value if value not set blade

Use php's null coalesce operator:

{{ $variable ?? "Default Message" }}

Removed as of Laravel 5.7

With Laravel 4.1-5.6 you could simply do it like this:

{{ $variable or "Default Message" }}

It's the same as:

echo isset($variable) ? $variable : 'Default Message';

PHP 5.3's ternary shortcut syntax works in Blade templates:

{{ $foo->bar ?: 'baz' }}

It won't work with undefined top-level variables, but it's great for handling missing values in arrays and objects.

Also, for instance, if we want to show up the date an organization was created, which might not exist (for example, if we create it manually from the DB and don't link to it any records for that field), then do something like

{{ $organization->created_at ? $organization->created_at->format('d/m/Y H:i') : "NULL" }}

Since Laravel 5.7 {{$Variable or "Default Message"}} throws $Variable is not defined. This {{$Variable ?? "Default Message"}} works though.

I recommend setting the default value in your controller instead of making a work-around in your view.

This is the best way because it keeps logic out of your view, and keeps the view's markup clean.

For example in your controller, before passing data to the view:

if(!isset($foo['bar'])){
     $foo['bar'] = 'baz';
}

Usually I use the null coalescing operator (introduced in PHP 7.0):

{{ $foo['bar'] ?? 'baz' }}

However, if 'baz' is actually a long expression (such as several lines of HTML, possibly with some PHP variables), then I use Blade‘s @isset (@else is optional but works):

@isset($foo['bar'])
    {{ $foo['bar'] }}
@else
    {{ $b }}
    <br>
    {{ $a }}
    <br>
    {{ $z }}
@endisset

(Taking a little liberty with the example, obviously.)

There’s also @empty($expr) which has similar syntax but works the same as the PHP function of the same name. This may be helpful: In where shall I use isset() and !empty()
