use ternary operator as if elseif and else

问题

I want to check if the role is agency then the output is $agencyUsers else if the role is officer then the output is $officeUsers else I need to output 'No Group'

I try this but the output is 'No Group' for all users

<td>{{ strtolower($user->getRoleNames()) === 'agency' ? $agencyUsers : strtolower($user->getRoleNames()) === 'officer' ? $officeUsers : 'No Group'}}</td>

回答1:

You must wrap the second ternary in parentheses, this should work:

strtolower($user->getRoleNames()) === 'agency' ? $agencyUsers : (strtolower($user->getRoleNames()) === 'officer' ? $officeUsers : 'No Group')

However, I recommend using a different approach. Blade allows for if conditions, which may be more readable than multiple ternaries, or even extracting this logic to a view function.
