I'm having trouble understanding the logic behind the Laravel @error blade directive. How does it work with $message enclosed within the @error directive? How does it know which $message to display? I would like to understand the PHP equivalent and how it operates behind the scenes.
@error('name')
<span class="invalid-feedback" role="alert">
<strong>{{ $message }}</strong>
</span>
@enderror
See framework code. https://github.com/laravel/framework/blob/11.x/src/Illuminate/View/Compilers/Concerns/CompilesErrors.php
The first commit is easier to understand. https://github.com/laravel/framework/commit/d5b80d727b6e426ce424be79b6016838c368504c
Similar code in older Laravel. @error just shortened this.
@if ($errors->has('name'))
<span class="invalid-feedback" role="alert">
<strong>{{ $errors->first('name') }}</strong>
</span>
@endif
