Dependent Dynamic dropdown using Angular Js and Laravel 5.6 – onlinecode
In this post we will give you information about Dependent Dynamic dropdown using Angular Js and Laravel 5.6 – onlinecode. Hear we will give you detail about Dependent Dynamic dropdown using Angular Js and Laravel 5.6 – onlinecodeAnd how to use it also give you demo for it if it is necessary.
The Dynamic Dependent Select Box is mostly used for the Nation-State-City dropdown in various web applications. In this article, we are going to build up this dropdown feature using Laravel, Angular JS and MySQL. In this dropdown, State is connected with the Nation and City is connected with the State.
As soon as you will select the nation, state table will be reloaded with respective states of that nation and after selecting the states, city table will be reloaded with respective cities of that state.
The data will be brought from the database without reloading the page using Laravel, Angular JS and MySQL.
Go ahead and try this, you will see that its quite handy and easy to build up.
Step1: Create Table
In this first step, you can create tables using migration file or directly run the below code to create tables in your database.
You will know how to create tables using migration file by clicking :Dependent dropdown in Laravel
CREATE TABLE 'countries' (
'id' int(11) NOT NULL AUTO_INCREMENT,
'name' varchar(100) NOT NULL,
'created_at' timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP,
'updated_at' datetime DEFAULT NULL,
PRIMARY KEY ('id')
) ENGINE=InnoDB AUTO_INCREMENT=3 DEFAULT CHARSET=latin1
CREATE TABLE 'states' (
'id' int(11) NOT NULL AUTO_INCREMENT,
'country_id' int(11) NOT NULL,
'name' varchar(100) NOT NULL,
'created_at' timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP,
'updated_at' datetime DEFAULT NULL,
PRIMARY KEY ('id')
) ENGINE=InnoDB AUTO_INCREMENT=3 DEFAULT CHARSET=latin1
CREATE TABLE 'cities' (
'id' int(11) NOT NULL AUTO_INCREMENT,
'state_id' int(11) NOT NULL,
'name' varchar(100) NOT NULL,
'created_at' timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP,
'updated_at' datetime DEFAULT NULL,
PRIMARY KEY ('id')
) ENGINE=InnoDB AUTO_INCREMENT=3 DEFAULT CHARSET=latin1
Step1: Add Route
Route::get('dependent-dropdown','APIController@index');
Route::get('get-country-list','APIController@getCountryList');
Route::get('get-state-list','APIController@getStateList');
Route::get('get-city-list','APIController@getCityList');
Step 3: Create APIControlle.php File
<?php namespace AppHttpControllers; use AppHttpRequests; use IlluminateHttpRequest; use DB; classAPIControllerextends Controller { publicfunctionindex() { return view('dependent_dropdown'); } publicfunctiongetCountryList(Request $request) { $countries= DB::table("countries") ->select("name","id") ->get(); return response()->json($countries); } publicfunctiongetStateList(Request $request) { $states= DB::table("states") ->where("country_id",$request->country_id) ->select("name","id") ->get(); return response()->json($states); } publicfunctiongetCityList(Request $request) { $cities= DB::table("cities") ->where("state_id",$request->state_id) ->select("name","id") ->get(); return response()->json($cities); } }
Step 4: Create dependent_dropdown.blade.php file
In this last step, I will create “dependent_dropdown.blade.php” file.
<!DOCTYPE html> <html> <head> <title>Dependent Dynamic dropdown using Angular Js and Laravel 5.6 - onlinecode</title> <script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.5.7/angular.min.js"></script> <linkrel="stylesheet"href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css"/> </head> <body> <divclass="container"style="width:500px;"> <h3align="center">Dependent Dynamic dropdown using Angular Js and Laravel 5.6 - onlinecode</h3> <br/> <divng-app="demoapp"ng-controller="democontroller"ng-init="loadCountry()"> <selectname="country"ng-model="country"class="form-control"ng-change="loadState()"> <optionvalue="">Select country</option> <optionng-repeat="country in countries"value="<% country.id %>"><% country.name %></option> </select> <br/> <selectname="state"ng-model="state"class="form-control"ng-change="loadCity()"> <optionvalue="">Select state</option> <optionng-repeat="state in states"value="<% state.id %>"><% state.name %></option> </select> <br/> <selectname="city"ng-model="city"class="form-control"> <optionvalue="">Select city</option> <optionng-repeat="city in cities"value="<% city.id %>"> <% city.name %> </option> </select> </div> </div> </body> </html> <script> var app = angular.module('demoapp', [], function($interpolateProvider) { $interpolateProvider.startSymbol('<%'); $interpolateProvider.endSymbol('%>'); }); app.controller("democontroller", function($scope, $http){ $scope.loadCountry =function(){ var url="{{url('get-country-list')}}"; $http.get(url) .success(function(data){ $scope.countries = data; }) } $scope.loadState =function(){ var url="{{url('get-state-list')}}?country_id="+$scope.country; $http.get(url) .success(function(data){ $scope.states = data; }) } $scope.loadCity =function(){ var url="{{url('get-city-list')}}?state_id="+$scope.state $http.get(url) .success(function(data){ $scope.cities = data; }); } }); </script>
As we know, both Angular and Laravel have same syntax to use double curly brackets :
<code>{{ variable }}</code>
So I changed the Angular Tags by using following code :
var app = angular.module('demoapp', [], function($interpolateProvider) { $interpolateProvider.startSymbol('<%'); $interpolateProvider.endSymbol('%>'); });
Now Angular will use <% variable %> and Laravel will use {{ variable }}.
You can alse change the Laravel Blade Tags if you want to use default Angular syntax.
