Using HTML5 file uploads with AJAX and jQuery
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 = event.target.result; 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, $data);
fclose($fp);
$retData = array( "myServerFile" => $myServerFile );
echo json_encode($retData);
