I am trying to upload multiple images to a folder at a time by using AJAX, JQuery, and PHP. The code is running for single file upload but not running for multiple image upload. If I am uploading a single image without loop then its working fine but in case of loop it's not working.
I am using the following code.
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Upload Iamge</title>
<link href="style.css" rel="stylesheet" type="text/css">
<script src="jquery-1.12.0.min.js"></script>
<script type="text/javascript">
$(document).ready(function(){
$("#but_upload").click(function(){
var fd = new FormData();
//following code is working fine in for single image upload
// var files = $('#file')[0].files[0];
// fd.append('file',files);
//this code not working for multiple image upload
var names = [];
for (var i = 0; i < $('#file').get(0).files.length; ++i) {
names.push($('#file').get(0).files[i].name);
}
fd.append('file[]',names);
/*var ins = document.getElementById('file').files.length;
for (var x = 0; x <ins; x++) {
fd.append("file", document.getElementById('file').files[x]);
}*/
$.ajax({
url:'upload.php',
type:'post',
data:fd,
contentType: false,
processData: false,
success:function(response){
if(response != 0){
$("#img").attr("src",response);
}
},
error:function(response){
alert('error : ' + JSON.stringify(response));
}
});
});
});
</script>
</head>

have made changes in below code
var file_data = $('input[type="file"]')[0].files; // for multiple files
for(var i = 0;i<file_data.length;i++){
fd.append("file_"+i, file_data[i]);
}
fd.append('file[]',names);
And there are also changes in PHP code
<?php
/* Getting file name */
//without loop working fine
$count = count($_FILES);
for ($i = 0; $i < $count; $i++) {
$filename = $_FILES['file_'.$i];
/* Location */
echo $location = "upload/".$filename['name'];
/* Upload file */
if(move_uploaded_file($filename['tmp_name'],$location)){
echo $location;
} else {
echo 0;
}
}
?>
count of files and file name are comming in a different way so I have made the changes as required instead of if gives file array like $_FILE['file_0'],$_FILE['file_1'] and so on, I have also change the permission of upload directory please check if your directory have read and write permission (777) or not, this code works for me you can try I hope it will work for you also :-)
