$scope.updateFunction = function(updateId) {
$http.get("http://localhost/crud/public/registration_update_page/" + updateId).then(function successCallback(response) {

Controller
<?php
namespace App\Http\Controllers;
use App\Http\Requests;
use Illuminate\Http\Request;
use DB;
use Session;
use Redirect;
class NewController extends Controller
{
/**
* Create a new controller instance.

public function __construct()
{
$this->middleware('auth');
}
public function registration_update_function(Request $request)
{
$updateId = $request->id;
$edited_name = $request->edited_name;
$edited_city = $request->edited_city;
$users1 = DB::table('angular_registration')->where('id', '=', $updateId)->update(['city' => $edited_city]);
}
}

Try with post method and following code and pass full x object / scope and x.id in this function updateFunction(x, x.id);
Angular Code
var req = {
method: 'POST',
url: 'http://localhost/crud/public/registration_update_page/',
data: { x: x, id = x.id }
}
$http(req).then(function(){
//Success
}, function(){
});
On server side PHP
print_r($_POST);

I solved this problem myself
This works for ANGULAR.JS with Laravel 4 to run insert,update,delete and select queries of the MySql DataBase.

Click post link to display full results on another page

I want to click on a link with id from database (on posts.html page) then view the full content of that post link in a display.html using AngularJS, MySQLi, and PHP. Please see the image below:
here is what I have managed to do so far:
Posts.html
<table class="table table-bordered" ng-controller="postController"
ng-init="show_data()">
<tr>
<th>Description</th>
</tr>
<tr ng-repeat="x in news">
<td>{{x.description}}</td>
</tr>
</table>
Here is my post controller: postController.js
"USE STRICT";
app.controller('postController', function ($scope, $http) {
$scope.show_data = function () {
$http.get("display.php")
.success(function (data) {
$scope.news = data;
});
}
});
And here is my display.php code:
<?php
require_once "config.php";
$output = array();
$query = "SELECT * FROM news";
$result = mysqli_query($conn, $query);
if (mysqli_num_rows($result) > 0) {
while ($row = mysqli_fetch_array($result)) {
$output[] = $row;
}
echo json_encode($output);
}
?>
My display.html is:
<div >
<div>{{id}}</div>
<div>{{title}}</div>
<div>{{article}}</div>
<div>{{tag}}</div>
<div>{{author}}</div>
</div>
How to display the results fetched from the database of the particular link on display.html?
This should do the job:
In your config:
app
.config(function ($routeProvider ...) {
$routeProvider
...
.when('/posts', {templateUrl: 'posts.html', controller: function($scope, $http) {
$scope.getPosts = function() {
$http.get('posts.php').then(function (response) {
$scope.posts = response.data;
});
};
}})
.when('/display/:id', {templateUrl: 'display.html', controller: function($scope, $routeParams, $http) {
$http.get('display.php', {id: $routeParams.id}).then(function (response) {
$scope.post = response.data;
});
}})
})
In posts.html:
<table class="table table-bordered" ng-controller="postController" ng-init="getPosts()">
<tr>
<th>Description</th>
</tr>
<tr ng-repeat="post in posts">
<td><a ng-href="display/{{post.id}}">{{post.description}}</a></td>
</tr>
</table>
In display.html:
<div ng-if="post">
...
<div>{{post.title}}</div>
...
</div>
In display.php:
$id = $_GET['id'];
// then retrieve post by this id and return as json item

Angular JS Json data

I am self educating myself in angular js. For this i have created a project modelled after an actual project in my job
All get operation work fine but POST is giving me issue
My controller.js
var ngapp = angular.module('ngWebApp', ['angularUtils.directives.dirPagination']);
ngapp.controller('ngIndexController', function ($scope, ngDashboardService) {
$scope.exportData = function (selectedDataList) {
var getData = ngDashboardService.AddReportAudit(selectedDataList)
getData.then(function (result) {
alert(result.data);
}, function () {
alert('Error in getting records');
});
};
});
My service.js
angular.module('ngWebApp').service("ngDashboardService", function ($http) {
this.AddReportAudit = function (dataList) {
var response = $http({
method: "POST",
url: "/Home/AddReportAudit",
data: {
'dataList': JSON.stringify(dataList)
}
});
return response;
};
});
My code of JasonResult in HomeController
public JsonResult AddReportAudit(List<ADTOWebSMARTT_SSOData> dataList)
{
if (dataList != null)
{
using (HRMSystemEntities contextObj = new HRMSystemEntities())
{
var itemList = dataList.Where(x => x.IsChecked == true).ToList();
itemList.ForEach(a => a.DateChecked = DateTime.Now);
contextObj.SaveChanges();
return Json(new { success = true });
}
}
else
{
return Json(new { success = false });
}
}
The problem occurs here
public JsonResult AddReportAudit(List dataList)
For some reason the dataList on reaching AddReportAudit become empty i.e. list has zero element. dataList has 30 records in controller.js and service.js.
I am not sure why that is happening. is there a parsing that I am missing when json data comes from angular to c#
You are actually sending an Object, so the data that reaches your public JsonResult AddReportAudit(....isAnObject), but you are expecting it to be a list. Just change your controller code to the snippet below, it should work.
angular.module('ngWebApp').service("ngDashboardService",
function($http) {
this.AddReportAudit = function (dataList) {
var response = $http({
method: "POST",
url: "/Home/AddReportAudit",
data:JSON.stringify(dataList)
});
return response;
};
});
Solution for angular 1. Place your web service url and change the json data format as per your need. It works.

You should call a function that gets your data again, after an insert. Apoloies for any errors in the code, I'm not used to injecting scope in angular controllers.
For example:
var app = angular.module('myApp', []);
app.controller('myCtrl', function($scope,$http) {
//$scope.insertFunc = function(lngth, brdth) {
//$http.get("http://localhost/crud/public/insert_rectangle_dimension_page/"+lngth+"/"+brdth)
$scope.insertFunc = $timeout(function(lngth,brdth) {
$scope.lngtha = lngth;
$scope.brdtha = brdth;
$http({

url : 'http://localhost/crud/public/insert_rectangle_dimension_page',
data : {lngth:$scope.lngth, brdth:$scope.brdth}

how to display model object in angular js?

Here is my RestController Class
#RestController
#RequestMapping(value="/user")
public class Test {
#RequestMapping(value="/{userEmailId}",method=RequestMethod.GET)
public ModelAndView getUser(#PathVariable("userEmailId") String userEmailId){
//something goes here and get User class object
ModelAndView mav=new ModelAndView("showuser");
mav.addObject("user", user);//user is User class object
return mav;
}
}
I want to display this user object in showuser.jsp using Angular JS How can I do that?
Below is sample example assuming your user object have firstname and lastname:
<head>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.3.3/angular.min.js"></script>
</head>
<div ng-app="myApp" ng-controller="userController">
<form action="demo_form.html">
First name: <input type="text" name="fname" ng-model="fname"><br>
Last name: <input type="text" name="lname" ng-model="lname"><br>
</form>
</div>
<script>
var app = angular.module('myApp', []);
app.controller('userController', function($scope, $http) {
$http({
method : "GET",
url : "/user/xyz#a.com"
}).then(function mySucces(response) {
$scope.fname = response.fname;
$scope.lname = response.lname;
}, function myError(response) {
//handling error
});
});
</script>

Not able to insert value in DB via Angular JS with MVC4

I built a sample MVC application in which I tried to implement functionality to insert a record using angular js.
Here is the index cshtml page.
#{
ViewBag.Title = "Add User";
Layout = "~/Views/Shared/_Layout.cshtml";
}
#section adduser
{
#*Index.html*#
<div class="container-fluid" ng-app='MyData' ng-controller='DataController'>
<table class="table table-striped table-bordered table-responsive">
<tr>
<td>
<label class="text-primary">User Name:</label>
</td>
<td>
<input type="text" id="txtUserName" class="text-primary" required="required" ng-model="newUser" />
</td>
</tr>
<tr>
<td colspan="2">
<input type="submit" id="btnSubmit" class="btn btn-success" ng-click="AddUser()" />
</td>
</tr>
</table>
</div>
}
Here is the Model js code
var myData = angular.module('MyData', []);
Here is the controller JS code
myData.controller("DataController", function($scope) {
$scope.newUser = "";
$scope.addUser = function() {
$http.post("/Home/AddUser/", { newUser: $scope.newUser }).success(function (result) {
alert(result.success);
}).error(function(data) {
console.log(data);
});
};
});
Here is the post method inside controller which i am calling through angular js
[HttpPost]
public JsonResult AddUser(string name)
{
var db = new SchedulerEntities();
db.Users.Add(new User {Name = name});
db.SaveChanges();
return null;
}
I am adding an entry into DB from controller method but nothing is happening...
I think you need to declare $http in the function:
myData.controller("DataController", function($scope, $http) {
$scope.newUser = "";
$scope.addUser = function() {
$http.post("/Home/AddUser/", { newUser: $scope.newUser })
.success(function (result) {
alert(result.success);
}).error(function(data) {
console.log(data);
});
};
});
