Scroll to validation errors in Laravel using Alpine.js
You know Laravel has this neat Blade directive called @error which you can use to display the validation error message for a given field. For instance, if you have a name field in your form and you want to display the validation error message for it, you can do it like so.
<label for="name">Name</label>
<input id="name"
type="text"
class="@error('name') is-invalid @enderror">
@error('name')
<div class="alert alert-danger">{{ $message }}</div>
@enderror
As you can tell, the @error directive will display the validation error message for the name field if there’s any. But the problem with this is, that if the form is long and the validation error occurs in a place that is not in the viewport, the user will not be able to see the error message. And this is not a good user experience.
This can be fixed with the help of Alpine.js as described precisely in this tweet by Caleb Porzio.
So, what you can do is, you can add a x-init directive on the error message container and then call a method that will scroll the page to the error message container if the error message container is visible on the page.
@error('name')
<div
class="alert alert-danger"
x-init="$el.closest('form').scrollIntoView()"
>
{{ $message }}
</div>
@enderror
The code in the x-init directive will scroll the page to the nearest form element if the error message container is visible on the page. This way, the user will be able to see all the validation errors even if they are not in the viewport.
