I am using Laravel 5.2 and have done as per above. When I type something in text box it shows all result set not the particular result. Could you please help in this regard ?

great !!

I am trying to make this work on Laravel 5.4 basic differences with the original is using Request instead of Input and response()->json($results) intead of Response::json

My text field send the request to the route and I got a 200 response (and if a see it on the browser is correct), but I am getting this error on the console:
TypeError: elem.getClientRects is not a function

And is not displaying the options.

Please advice

EDIT: That error was coming from using jquery-ui-bundle (because somehow jquery-ui is not Mix friendly) and bundle is stuck on 1.11.x and that won't work with jquery 3.x. Solved by placing jquery-ui manually on resources.

Now all seems to work, except there is not displaying of options whatsoever

@gassius This code can actually be simplified quite a bit, here is my implementation with Laravel 5.4. No need for foreach looping through the data.

SearchController.php:

public function autocomplete()
{
	$term = request('term');
        $result = Model::whereName($term)->orWhere('name', 'LIKE', '%' . $term . '%')->get(['id', 'name as value']);
        return response()->json($term);
}

Model and query should be adjusted to search the data source you require, plus a limit with take() if required.

You should also avoid hardcoding the source URL. It can be done like this:

routes/web.php:

Route::get('search/autocomplete', ['as' => 'search-autocomplete', 'uses' => 'SearchController@autocomplete']);

view:

<input type="text" name="term" id="q" data-action="{{ route('search-autocomplete') }}">

We're referencing the action with the route() helper in a data-action attribute, this can now be passed through to the JS file like so:

$('#q').each(function() {
        var $this = $(this);
        var src = $this.data('action');

        $this.autocomplete({
            source: src,
            minLength: 2,
            select: function(event, ui) {
                $this.val(ui.item.value);
                $('#id').val(ui.item.id);
            }
        });
    });

source is assigned the route from data-action, which is defined in our routes file. No need for hard coding urls.

Bonus. I've added a hidden field to the form to capture the ID of the selection

{!! Form::hidden('source_id', ['class' => 'source_id', 'id' => 'source_id']) !!}

source_id should obviously reflect the column name.

Hope this helps

@goodbytes-gb thxx a lot !
Just one thing: where (and how) do you add

{!! Form::hidden('source_id', ['class' => 'source_id', 'id' => 'source_id']) !!}

I am a beginner at laravel

Great script its working fine.

Style it with Bootstrap:
https://stackoverflow.com/questions/17838380/styling-jquery-ui-autocomplete

is very good and very easy.Thank!!! Please someone have one idea about implement a cache too in this code.

@gdbyte's code works perfectly, however, you need to change the SearchController.php code from:
return response()->json($term);
to:
return response()->json($result);

You'll also need to make sure you include jQuery UI in your project, otherwise, you'll get an error saying that the autocomplete function doesn't exist.

Hi, I know i'm late, But i'm doing the same thing and yes it works but man its slow. How do I return the results more faster

@non-entity9 , I am also trying to get @gdbytes code to work:
-created SearchController.php and added his code. Updated model and query
-added route
-added input to view
-not sure where to put the JS file. Where do you put that?

What else do I need to do to get this to work? Thx in advance

Other than plugin, it is also necessary to intetgrate some full text search functionality, like Elasticsearch? I think autocomplete search works well when Elasticsearch is configure in the Laravel model.

Uncaught TypeError: $(...).autocomplete is not a function .........any solutions ?

I noticed that your web page does not include the JS library from jQuery Ui's CSS and JS library.

Firstly, include the following libaries into your web pages:

<link rel="stylesheet" href="//code.jquery.com/ui/1.12.1/themes/base/jquery-ui.css">
<!-- jQuery -->
<script src="https://code.jquery.com/jquery-3.6.0.min.js"></script>
<!-- jQuery UI -->
<script src="https://code.jquery.com/ui/1.12.1/jquery-ui.min.js"></script>
<script type="text/javascript">
