Tutorial: Delete Multiple Rows using AngularJS with PHP/MySQLi with Source Code
Getting Started on How to Delete Multiple Rows using AngularJS
Delete Multiple Rows using AngularJS with PHP/MySQLi is our tutorial for today. I’ve used CDN for Bootstrap and AngularJS, so you need an internet connection for them to work.
Creating a Database
First, we’re going to create our database and insert sample data that you can use in deleting.
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;
INSERT INTO `members` (`memid`, `firstname`, `lastname`, `address`) VALUES (1, 'Lyndon', 'Bermoy', 'India'), (2, 'Julyn', 'Divinagracia', 'E.B. Magalona'), (3, 'Gemalyn', 'Cepe', 'Bohol'), (4, 'Matet', 'Devierte', 'Silay City'), (5, 'Tintin', 'Devierte', 'Silay City'), (6, 'Bien', 'Devierte', 'Cebu City'), (7, 'Cherry', 'Ambayec', 'Cebu City'), (8, 'Jubilee', 'Limsiaco', 'Silay City'), (9, 'Janna ', 'Atienza', 'Talisay City'), (10, 'Desire', 'Osorio', 'Bacolod City'), (11, 'Debbie', 'Osorio', 'Talisay City'), (12, 'Nipoy ', 'Polondaya', 'Victorias City'), (13, 'Johnedel', 'Balino', 'Cauyan, Negros'), (14, 'Nereca', 'Tajonera', 'Cauayan, Negros'), (15, 'Jerome', 'Robles', 'Cebu City');

Next, this is a index that contains a table.

This contains a angular.js script.
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.toggleAll = function(){
for (var i = 0; i < $scope.members.length; i++) {
$scope.members[i].Selected = $scope.checkAll;
}
};
$scope.toggleOne = function(){
$scope.checkAll = true;
for (var i = 0; i < $scope.members.length; i++) {
if (!$scope.members[i].Selected) {
$scope.checkAll = false;
break;
}
};
};
$scope.deleteAll = function(){
checkedId = [];
for (var i = 0; i < $scope.members.length; i++) {
if ($scope.members[i].Selected) {
checkedId.push($scope.members[i].memid);
}
}
$http.post("delete.php", checkedId)
.success(function(data){
console.log(data);
if(data.error){
$scope.error = true;
$scope.success = false;
$scope.errorMessage = data.message;
$scope.checkAll = false;
}
else{
$scope.success = true;
$scope.error = false;
$scope.successMessage = data.message;
$scope.fetch();
$scope.checkAll = false;
}
});
}
$scope.clearMessage = function(){
$scope.success = false;
$scope.error = false;
}
});fetch.php
This is a PHP api/code that fetches table 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);
?>delete.php
Lastly, this is a PHP code/api in deleting the checked rows of a table.
<?php
$conn = new mysqli('localhost', 'root', '', 'angular');
$data = json_decode(file_get_contents("php://input"));
$out = array('error' => false);
foreach ($data as $key => $value) {
$sql = "DELETE FROM members WHERE memid = '".$value."'";
$query = $conn->query($sql);
}
if($query){
$out['message'] = "Member(s) deleted Successfully";
}
else{
$out['error'] = true;
$out['message'] = "Something went wrong. Cannot delete Member(s)";
}
echo json_encode($out);
?>
