How to get data from MySQL with AngularJS – PHP
How to get data from MySQL with AngularJS – PHP
With only using AngularJS it is not possible to get data from MySQL database because it only handles Client side requests.
You have to use any Server side language at backend which handles the request and returns response.
In AngularJS $http service is use to send AJAX request
Contents
1. Table structure
I am using
users table in the tutorial example.CREATE TABLE `users` ( `id` int(11) NOT NULL PRIMARY KEY AUTO_INCREMENT, `fname` varchar(80) NOT NULL, `lname` varchar(80) NOT NULL, `username` varchar(80) NOT NULL ) ENGINE=InnoDB DEFAULT CHARSET=latin1;
2. Configuration
Create a new
config.php file.
Completed Code
<?php
$host = "localhost"; /* Host name */
$user = "root"; /* User */
$password = ""; /* Password */
$dbname = "tutorial"; /* Database name */
$con = mysqli_connect($host, $user, $password,$dbname);
// Check connection
if (!$con) {
die("Connection failed: " . mysqli_connect_error());
}
3. HTML
You can either download and include
angular.min.js in the page or use CDN.<script src='https://ajax.googleapis.com/ajax/libs/angularjs/1.6.1/angular.min.js'></script>
Define
<body ng-app='myapp'> and <div ng-controller='userCtrl'> on the page.
For displaying data create a
<table> layout and specify ng-repeat directive on a row. Which loop through all available data in users property.
Completed Code
<!doctype html>
<html>
<head>
<title>How to get data from MySQL with AngularJS - PHP</title>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.6.1/angular.min.js"></script>
</head>
<body ng-app='myapp'>
<div ng-controller="userCtrl">
<table >
<tr>
<th>First name</th>
<th>Last name</th>
<th>Username</th>
</tr>
<!-- Display records -->
<tr ng-repeat="user in users">
<td>{{user.fname}}</td>
<td>{{user.lname}}</td>
<td>{{user.username}}</td>
</tr>
</table>
</div>
</body>
</html>
4. PHP
Create new
getData.php file.
From here return JSON Array which has user details (fname, lname, and username).
Completed Code
include 'config.php';
$sel = mysqli_query($con,"select * from users");
$data = array();
while ($row = mysqli_fetch_array($sel)) {
$data[] = array("fname"=>$row['fname'],"lname"=>$row['lname'],"username"=>$row['username']);
}
echo json_encode($data);
5. Script
Create new module and setup AJAX request in controller ( userCtrl ).
- Path – Passing file name
getData.phpinurland setmethodtoget. - Success – AJAX successfully callback handle by
thenwhere storereponse.datato$scope.users.
At HTML end display data using
ng-repeat directive.
Completed Code
<script>
var fetch = angular.module('myapp', []);
fetch.controller('userCtrl', ['$scope', '$http', function ($scope, $http) {
$http({
method: 'get',
url: 'getData.php'
}).then(function successCallback(response) {
// Store response data
$scope.users = response.data;
});
}]);
</script>
6. Conclusion
Angular provide
$http service which helps to make an AJAX call to the server.
Similar to jQuery AJAX request you can either send GET or POST type request. Within tutorial example, I send GET request from
$http to fetch data from MySQL database in JSON format.
