Creating a Database

First, we are going to create our database.

1. Open phpMyAdmin.

2. Click databases, create a database and name it as angular.

3. After creating a database, click the SQL and paste the below codes. See image below for detailed instruction.

CREATE TABLE `members` (
  `memid` int(11) NOT NULL AUTO_INCREMENT,
  `firstname` varchar(30) NOT NULL,
  `lastname` varchar(30) NOT NULL,
  `address` text NOT NULL,
PRIMARY KEY(`memid`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1;

index.html

Next, this is a index that contains an add form.

angular.js

var app = angular.module('app', []);
app.controller('memberdata', function($scope, $http){
    $scope.success = false;
    $scope.error = false;
 
    $scope.fetch = function(){
    	$http.get("fetch.php").success(function(data){ 
            $scope.members = data; 
        });
    }
 
    $scope.memberfields = [{id: 'field1'}];
 
    $scope.newfield = function(){
        var newItem = $scope.memberfields.length+1;

    }
 
    $scope.submitForm = function(){
        $http.post('add.php', $scope.memberfields)
        .success(function(data){
            if(data.error){

    $scope.clearMessage = function(){
    	$scope.success = false;
    	$scope.error = false;

});

fetch.php

This is a PHP api/code that fetches data from a MySQL database.

<?php
    $conn = new mysqli('localhost', 'root', '', 'angular');
 
    $output = array();
    $sql = "SELECT * FROM members";
    $query=$conn->query($sql);
    while($row=$query->fetch_array()){
        $output[] = $row;
    }
 
    echo json_encode($output);
?>

add.php

Lastly, this is a PHP api/code in adding one or multiple rows into a database on how to Add Form Fields Dynamically using AngularJS with PHP/MySQLi.

    $conn = new mysqli('localhost', 'root', '', 'angular');
 
    $data = json_decode(file_get_contents("php://input"));
 
    $count = count($data);
 
    $out = array('error' => false);
 
    foreach($data as $key => $value){
        $firstname = $value->firstname;
        $lastname = $value->lastname;
        $address = $value->address;
 
        $sql = "INSERT INTO members (firstname, lastname, address) VALUES ('$firstname', '$lastname', '$address')";
        $query = $conn->query($sql);
    }
 
    if($query){
        $out['message'] = "($count) Member/s added successfully";
    }
    else{
        $out['error'] = true;
        $out['message'] = "Cannot add Member(s)";

    echo json_encode($out);
?>
