Getting Started
I’ve used Bootstrap and Angular JS in this tutorial, so you need an internet connection for them to work. Angular JS version = 1.5.7.
Creating a Database
First, we’re 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 `upload` ( `uploadid` int(11) NOT NULL AUTO_INCREMENT, `original` varchar(150) NOT NULL, `new` varchar(150) NOT NULL, `type` varchar(10) NOT NULL, PRIMARY KEY(`uploadid`) ) ENGINE=InnoDB DEFAULT CHARSET=latin1;
index.php
Next, this is a index which contains our upload form and a uploaded files table.
<!DOCTYPE html>

</table>

angular.js
This contains a angular.js codes.
var app = angular.module('app', []);
app.directive('fileInput', ['$parse', function ($parse) {
return {
restrict: 'A',
link: function($scope, elm, attrs){
elm.bind('change', function(){
$parse(attrs.fileInput).assign($scope, elm[0].files);
$scope.$apply();
});
}
}
}]);
app.controller('uploader', function($scope, $http){
$scope.showProgress = false;
$scope.error = false;
$scope.errorMessage = "";
$scope.success = false;
$scope.successMessage = "";
$scope.upload = function(){
var uploadForm = new FormData();
angular.forEach($scope.files, function(file){
uploadForm.append('file[]', file);
});
$http.post('upload.php', uploadForm, {
transformRequest:angular.identity,
headers: {'Content-Type':undefined, 'Process-Data': false},
uploadEventHandlers: {
progress: function (e) {
if (e.lengthComputable) {
$scope.showProgress = true;
$scope.progressBar = (e.loaded / e.total) * 100;
$scope.progressCounter = $scope.progressBar.toFixed(2) + ' %';
}
}
}
})
.success(function(response){
console.log(response);
if(response.error){
$scope.error = true;
$scope.errorMessage = response.message;
}
else{
$scope.success = true;
$scope.successMessage = response.message;
$scope.fetch();
}
})
}
$scope.fetch = function(){
$http.get('fetch.php')
.success(function(data){
$scope.uploads = data;
});
}
$scope.clearMessage = function(){
$scope.error = false;
$scope.errorMessage = "";
$scope.success = false;
$scope.successMessage = "";
}
});
fetch.php
This is a PHP api/code that fetches a uploaded files.
<?php
$conn = new mysqli('localhost', 'root', '', 'angular');
$output = array();
$sql = "SELECT * FROM upload";
$query=$conn->query($sql);
while($row=$query->fetch_array()){
$output[] = $row;
}
echo json_encode($output);
?>
upload.php
Lastly, this is a PHP code/api in uploading a files.
<?php
$conn = new mysqli('localhost', 'root', '', 'angular');
$out = array('error' => false);
if(!empty($_FILES['file']['name'])){
$count = count($_FILES['file']['name']);
foreach ($_FILES['file']['name'] as $key => $filename){
$newFilename = time() . "_" . $filename;
$ext = strtoupper(pathinfo($filename, PATHINFO_EXTENSION));
$path = 'upload/' . $newFilename;
if(move_uploaded_file($_FILES['file']['tmp_name'][$key], $path)){
$sql = "INSERT INTO upload (original, new, type) VALUES ('$filename', '$newFilename', '$ext')";
$query=$conn->query($sql);
}
if($query){
if($count > 1){
$out['message'] = 'Files Uploaded Successfully';
}
else{
$out['message'] = 'File Uploaded Successfully';
}
}
else{
$out['error'] = true;
$out['message'] = 'File Uploaded but not Saved';
}
}
}
else{
$out['error'] = true;
$out['message'] = 'Upload Failed. File empty!';
}
echo json_encode($out);
?>
Note: You can increase the upload size of your localhost by setting the value of upload_max_filesize and post_max_size in your php.ini. Then, restart your localhost server to save your changes.
That ends this tutorial. Happy Coding!
