Laravel autocomplete from database
Autocomplete is such an important and most frequently used web component either you develop a website or software. There are so many options to make autocomplete from the database but jQuery UI autocomplete is most used one. In this post, I'll show you a complete step by step process on how to make laravel autocomplete from database using jQuery UI.
Plan
Suppose we have a product table with fields id, name, buy_rate, sale_price etc. In invoice creation, we need a autocomplete for selecting a product. After searching product by id, when we'll select a product it'll fill up Name, Buy Rate, Sale Price input automatically.
Step 1: Add jQuery
First, we need to add jQuery in our template header section.
<script src="https://unpkg.com/jquery@2.2.4/dist/jquery.js"></script>
Step 2: Add jQuery UI dependency
Now add jQuery UI js file and jQuery UI CSS file at the bottom of your template.
<script src="https://code.jquery.com/ui/1.11.4/jquery-ui.min.js"></script>
<link href="https://code.jquery.com/ui/1.11.3/themes/smoothness/jquery-ui.css"/>
Step 3: Define Route
We need 2 routes. One for just showing our view where we'll build our autocomplete and another for JSON API service for feeding JSON to our jQuery UI autocomplete.
Route::get('admin/invoice/create','InvoiceController@create');
Route::get('admin/api/product','InvoiceController@getAutocompleteData');
Step 3: Make JSON service
Now we need to a JSON API service for our autocomplete. Let's do code in InvoiceController for making JSON API service and returning a view for autocomplete.
<?php
namespace App\Http\Controllers;
use App\Product;
use Illuminate\Http\Request;
class InvoiceController extends Controller
{
public function getAutocompleteData(Request $request){
if($request->has('term')){
return Product::where('name','like','%'.$request->input('term').'%')->get();
}
}
public function create(){
return view('admin.invoices.create');
}
}
Step 4: Make view
Add a create.blade.php view in resources/admin/invoices directory and do markup for autocomplete.
@extends('app')
@section('content')
<div class="container">
<div class="row">
<div class="col-md-4">
<h4>Autocomplete from database</h4>
<hr>
<div class="form-group">
<label>Product</label>
<input id="product_id" name="product_id" type="text" class="form-control">
</div>
<div class="form-group">
<label>Name</label>
<input id="name" type="text" class="form-control">
</div>
<div class="form-group">
<label>Buy Rate</label>
<input id="buy_rate" type="text" class="form-control">
</div>
<div class="form-group">
<label>Sale Price</label>
<input id="sale_price" type="text" class="form-control">
</div>
</div>
</div>
</div>

Step 5: Do Js code for autocomplete
Now we need to work in js part for doing autocomplete. You can do this code at the end of create.blade.php file with a script tag or you can use a separate file by using the reference of that.
$(function () {
$('#product_id').autocomplete({
source:function(request,response){
$.getJSON('?term='+request.term,function(data){
var array = $.map(data,function(row){
return {
value:row.id,
label:row.name,
name:row.name,
buy_rate:row.buy_rate,
sale_price:row.sale_price
}
})
response($.ui.autocomplete.filter(array,request.term));
})
},
minLength:1,
delay:500,
select:function(event,ui){
$('#name').val(ui.item.name)
$('#buy_rate').val(ui.item.buy_rate)
$('#sale_price').val(ui.item.sale_price)
}
})
})Ok done. The final view code with Js part will be like below.
@extends('app')
@section('content')
<div class="container">
<div class="row">
<div class="col-md-4">
<h4>Autocomplete from database</h4>
<hr>
<div class="form-group">
<label>Product</label>
<input id="product_id" name="product_id" type="text" class="form-control">
</div>
<div class="form-group">
<label>Name</label>
<input id="name" type="text" class="form-control">
</div>
<div class="form-group">
<label>Buy Rate</label>
<input id="buy_rate" type="text" class="form-control">
</div>
<div class="form-group">
<label>Sale Price</label>
<input id="sale_price" type="text" class="form-control">
</div>
</div>
</div>
</div>
<script>
$(function () {
$('#product_id').autocomplete({
source:function(request,response){
$.getJSON('?term='+request.term,function(data){
var array = $.map(data,function(row){
return {
value:row.id,
label:row.name,
name:row.name,
buy_rate:row.buy_rate,
sale_price:row.sale_price
}
})
response($.ui.autocomplete.filter(array,request.term));
})
},
minLength:1,
delay:500,
select:function(event,ui){
$('#name').val(ui.item.name)
$('#buy_rate').val(ui.item.buy_rate)
$('#sale_price').val(ui.item.sale_price)
}
})
})
</script>
