Check if a variable exists in Laravel Blade templates

July 20, 2022  ‐ 1 min read

This might now be a common use-case, but let's say for example you need to check if a Laravel Blade layout template whether a variable exists.

In regular PHP code you can use the isset() function for this. In Blade there is a directive which allows for such a check.

{{ $obj }}

In case you need to check whether a variable exists in conjunction with another check you can just use the regular @if directive.

@if(isset($obj) && gettype($ob) === 'object')
{{ $obj }}
