How to post form data using angularjs and process in php

Most of developers using jquery, ajax to post form data. But now a new library comes out with named angularjs. In angularjs $http service provided to communicate remote http servers. There are many ways to post form data using angularjs, but i am sharing a simple way. We’ll use a simple form that used to be submitted using PHP and how to convert that to Angular.

What we are building :-

Post form data using angularjs

  • 1. Setting up angularjs application/model/controller.
  • 2. Use angular object to get form data.
  • 3. Post form data using angularjs.
  • 4. Process/handle form data and errors in php.
  • 5. Show form success/errors using angularjs.

So let’s start step by step how to post form data using angularjs or submit form with angularjs.

1. The Form – Setting up angularjs application/model/controller :-

Let’s create html to show up form and initialize angularjs app.

<!DOCTYPE html>
    <link rel="stylesheet" href=""> 
    <script src= ""></script> 
<body ng-app="postApp" ng-controller="postController">
<div class="container">
<div class="col-sm-8 col-sm-offset-2">
    <div class="page-header"><h1>Post data using angularJS</h1></div>
    <!-- FORM -->
    <form name="userForm" ng-submit="submitForm()">
    <div class="form-group">
        <input type="text" name="name" class="form-control" ng-model="">
        <span ng-show="errorName">{{errorName}}</span>
    <div class="form-group">
        <input type="text" name="username" class="form-control" ng-model="user.username">
        <span ng-show="errorUserName">{{errorUserName}}</span>
    <div class="form-group">
        <input type="email" name="email" class="form-control" ng-model="">
        <span ng-show="errorEmail">{{errorEmail}}</span>
    <button type="submit" class="btn btn-primary">Submit</button>

Understanding the form :- We including angualrjs script library to work with angularjs like jquery.

<body ng-app="postApp" ng-controller="postController">

ng-app="postApp" – Directive that define angularjs application
ng-controller="postController" – Directives that define angularjs controller

<form name="userForm" ng-submit="submitForm()">

ng-submit="submitForm()" – We are calling a function on form submit

<span ng-show="errorName">{{errorName}}</span>
<span ng-show="errorUserName">{{errorUserName}}</span>
<span ng-show="errorEmail">{{errorEmail}}</span>

ng-show="errorName" – This will control to show errors. we will showing up errors in this span tag using ng-show directives.

For more information about directives follow Docs

2. Use angular object to get form data :-

We are using ng-model directive to define angular object we are using user object to process with form like, user.username

3. Post form data using angularjs :-

Let’s make angularjs script to post form data using angularjs. Add this script to your form to process. Here we are using POST method Submit Form with angularjs to php.

    // Defining angularjs application.
    var postApp = angular.module('postApp', []);
    // Controller function and passing $http service and $scope var.
    postApp.controller('postController', function($scope, $http) {
      // create a blank object to handle form data.
        $scope.user = {};
      // calling our submit function.
        $scope.submitForm = function() {
        // Posting data to php file
          method  : 'POST',
          url     : 'clone.php',
          data    : $scope.user, //forms user object
          headers : {'Content-Type': 'application/x-www-form-urlencoded'} 
          .success(function(data) {
            if (data.errors) {
              // Showing errors.
              $scope.errorName =;
              $scope.errorUserName = data.errors.username;
              $scope.errorEmail =;
            } else {
              $scope.message = data.message;

Understanding the script :-

$scope: is a object of application model For more follow Docs.
$http: The Angular service that will help to communicate remote http servers . For more information, check out the Docs.

4. Process/handle form data and errors in php :-

Now create a clone.php and add below code to show response or errors back to angularjs application.

$errors = array();
$data = array();
// Getting posted data and decodeing json
$_POST = json_decode(file_get_contents('php://input'), true);

// checking for blank values.
if (empty($_POST['name']))
  $errors['name'] = 'Name is required.';

if (empty($_POST['username']))
  $errors['username'] = 'Username is required.';

if (empty($_POST['email']))
  $errors['email'] = 'Email is required.';

if (!empty($errors)) {
  $data['errors']  = $errors;
} else {
  $data['message'] = 'Form data is going well';
// response back.
echo json_encode($data);

5. Show form success/errors using angularjs :-

We are using ng-show directive to show errors in our form. which we are sending back if form has any errors.

<span ng-show="errorName">{{errorName}}</span>
<span ng-show="errorUserName">{{errorUserName}}</span>
<span ng-show="errorEmail">{{errorEmail}}</span>

So now you can easily post form data using angularjs, you can also use $.param() method to convert user object in string and can get directly your post values. But we are working with angularjs so i am not including jquery here. So Now you can easily submit your form with angularjs.

  • Rishi Kumar

    Thanks, It was helpfull

  • Omar

    Here is a better way to understand it ( original way )

  • Vaios Anastasiadis

    One thing I can’t understand is the ng-show=”errorxxxx”. I presume that the ng-show is waiting for a true or false statement, correct? So how is a returned string like errorName being translated as true or false? Am I missing something?

    • Qrivi

      In JavaScript, each variable that holds a value will return true when used in a statement. So unless the string is empty, it will convert to a true.

      false, 0, empty strings ” and “”, NaN, undefined, and null are always evaluated as false; everything else is true.
