Ternary in Laravel Blade

In Laravel Blade, you can use ternary operators to write conditional expressions. The ternary operator allows you to write a shorthand if/else statement.

The syntax for using ternary operators in Blade is as follows:

{{ $variable ? 'true value' : 'false value' }}

Here, $variable is the variable that you want to evaluate. If the value of $variable is true, the expression will return ‘true value’, otherwise, it will return ‘false value’.

You can also nest ternary operators to create more complex conditional expressions. Here’s an example:

{{ $variable1 ? ($variable2 ? 'both true' : 'variable1 true, variable2 false') : 'variable1 false' }}

In this example, if $variable1 is true and $variable2 is true, the expression will return ‘both true’. If $variable1 is true and $variable2 is false, the expression will return ‘variable1 true, variable2 false’. If $variable1 is false, the expression will return ‘variable1 false’.

Note that you can also use the ternary operator in control structures such as if, elseif, and else statements. Here’s an example:

@if($variable)
    {{ $variable ? 'true value' : 'false value' }}
@elseif($variable2)
    {{ $variable2 ? 'true value' : 'false value' }}
@else
    {{ 'default value' }}
@endif

In this example, if $variable is true, the expression will return ‘true value’. If $variable is false and $variable2 is true, the expression will return ‘true value’. If both $variable and $variable2 are false, the expression will return ‘default value’.
