PHP $_FILES same image name - php

Question

I am trying to upload multiple images to php server, But for some reason it is using first image name for all the uploaded images, saving to same image name. I want it to save to their filename in the source folder. Like Banner1.jpg,Banner2.jpg and Banner3.jpg should be saved. But it is saving first image thrice.
$filesCount = count($_FILES['photos']['name']);
$success = 0;
for($i = 0; $i < $filesCount; $i++)
{
$uploadedfile = $_FILES['photos']['tmp_name'][$i];
if($uploadedfile)
{
$filename = stripcslashes($_FILES['photos']['name'][$i]);
$extension = $this->getExtension($filename);
$extension = strtolower($extension);
if (($extension != "jpg") && ($extension != "jpeg") && ($extension != "png") && ($extension != "gif"))
{
$change='<div class="msgdiv">Unknown Image extension </div>';
}
else
{
$size = filesize($_FILES['photos']['tmp_name'][$i]);
}
if($size > MAX_SIZE*1024)
{
$change='<div class="msgdiv">You have exceeded the size limit!</div> ';
}
if($extension=="jpg" || $extension=="jpeg" )
{
$uploadedfile = $_FILES['photos']['tmp_name'][$i];
$src = imagecreatefromjpeg($uploadedfile);
}
else if($extension=="png")
{
$uploadedfile = $_FILES['photos']['tmp_name'][$i];
$src = imagecreatefrompng($uploadedfile);
}
else
{
$src = imagecreatefromgif($uploadedfile);
}
list($width,$height)=getimagesize($uploadedfile);
$newwidth=1024;
$newheight=($height/$width)*$newwidth;
$tmp=imagecreatetruecolor($newwidth,$newheight);
$newwidth1=300;
$newheight1=($height/$width)*$newwidth1;
$tmp1=imagecreatetruecolor($newwidth1,$newheight1);
imagecopyresampled($tmp,$src,0,0,0,0,$newwidth,$newheight,$width,$height);
imagecopyresampled($tmp1,$src,0,0,0,0,$newwidth1,$newheight1,$width,$height);
$filenameee = "server/php/rental/". $_FILES['photos']['name'][$i];
$filenameee1 = "server/php/rental/small/". $_FILES['photos']['name'][$i];
imagejpeg($tmp,$filenameee,100);
imagejpeg($tmp1,$filenameee1,100);
imagedestroy($src);
imagedestroy($tmp);
imagedestroy($tmp1);
if(mysql_query("INSERT INTO fc_rental_photos(product_image,product_id) VALUES('$filename','$prd_id')"))
{
$success++;
}
}
Here is the input field i am using to upload images.
<form id="imageform" method="post" enctype="multipart/form-data" action="/path-to-controller-method/">
<input type="file" name="photos[]" id="photoimg" multiple onchange="imageval();">
</form>
IMageVal
function imageval(){ /*Image size validation*/
var fi = document.getElementById('photoimg');
if (fi.files.length > 0) { // FIRST CHECK IF ANY FILE IS SELECTED.
for (var i = 0; i <= fi.files.length - 1; i++) {
var fileName, fileExtension, fileSize, fileType, dateModified;
fileName = fi.files.item(i).name;
fileExtension = fileName.replace(/^.*\./, '');
if (fileExtension == 'png' || fileExtension == 'jpg' || fileExtension == 'jpeg') {
var reader = new FileReader();
//Read the contents of Image File.
reader.readAsDataURL(fi.files.item(i));
reader.onload = function (e) {
//Initiate the JavaScript Image object.
var image = new Image();
//Set the Base64 string return from FileReader as source.
image.src = e.target.result;
//Validate the File Height and Width.
image.onload = function () {
var height = this.height;
var width = this.width;
if (width < 1450 || height < 500) {
alert("Image Height and Width should be Above 1450 * 500 px.");
return false;
}
<?php if($aws == 'Yes') echo "uploadImage_aws();";else echo "uploadImage();";?>
};
}
}
else
{
alert("Photo only allows file types of PNG, JPG, JPEG. ");
}
}
}
}
UploadImage
function uploadImage()
{
$("#imageform").ajaxForm({target: '#preview',
beforeSubmit:function(){
$("#imageloadstatus").show();
$("#imageloadbutton").hide();
},
success:function(){
$("#imageloadstatus").hide();
$("#imageloadbutton").show();
},
error:function(){
$("#imageloadstatus").hide();
$("#imageloadbutton").show();
}
}).submit();
}

You have to check if the data already exists, and if not to rename it.
if(file_exists($new_path)) {
$id = 1;
do {
$new_path = $upload_folder.$filename.'_'.$id.'.'.$extension;
$id++;
} while(file_exists($new_path));
}
For example
$new_path = $upload_folder.$filename.'.'.$extension;
