Using HTML5 file uploads with AJAX and jQuery

HTMLWeb DevelopmentFront End Technology

When the form is submitted, catch the submission process and try to run the following code snippet for file upload −

// File 1
var myFile = document.getElementById('fileBox').files[0];
var reader = new FileReader();
reader.readAsText(file, 'UTF-8');
reader.onload = myFunc;

function myFunc(event) {
   var res =; var fileName = document.getElementById('fileBox').files[0].name;
   $.post('/myscript.php', { data: res, name: fileName }, continueSubmission);

Then, on the server side (i.e. myscript.php) −

$data = $_POST['data'];
$fileName = $_POST['name'];
$myServerFile = time().$fileName;

// Prevent overwriting
$fp = fopen('/uploads/'.$myServerFile,'w');
fwrite($fp, $data);
$retData = array( "myServerFile" => $myServerFile );
echo json_encode($retData);
