Multiple file upload is not working if all files are not the same extension !! If I chose two png files , it works . But choosing two different file extensions (png,pdf) got empty array in $_FILES

I think you can use following code :-
<button id="upload">Upload</button>
<script type="text/javascript">
$(document).ready(function (e) {
$('#upload').on('click', function () {
var form_data = new FormData();
var ins = document.getElementById('multiFiles').files.length;
for (var x = 0; x < ins; x++) {
form_data.append("files[]", document.getElementById('multiFiles').files[x]);
}
$.ajax({
url: 'uploads.php', // point to server-side PHP script
dataType: 'text', // what to expect back from the PHP script
cache: false,
contentType: false,
processData: false,
data: form_data,
type: 'post',
success: function (response) {
$('#msg').html(response); // display success response from the PHP script
},
error: function (response) {
$('#msg').html(response); // display error response from the PHP script
}
});
});
});
</script>
