Multiple image upload with PHP - php

Question

I'm trying upload multiple images. Below you can see my code.
Image uploaded massage repenting (exactly the amount of image chosen to upload.)
How can i show "Image uploaded" massage only ones on successful submit?
If i put the message after the loop it will start to show no matter if there is any errors.
This is my PHP code:
<?php
error_reporting(0);
session_start();
include('db.php');
$id = $mysqli->escape_string($_GET['id']);
define ("MAX_SIZE","9000");
function getExtension($str)
{
$i = strrpos($str,".");
if (!$i) { return ""; }
$l = strlen($str) - $i;
$ext = substr($str,$i+1,$l);
return $ext;
}
$valid_formats = array("jpg", "png", "gif", "jpeg");
if(isset($_POST) and $_SERVER['REQUEST_METHOD'] == "POST")
{
$uploaddir = "gallery/"; //a directory inside
foreach ($_FILES['photos']['name'] as $name => $value)
{
$filename = stripslashes($_FILES['photos']['name'][$name]);
$size=filesize($_FILES['photos']['tmp_name'][$name]);
//get the extension of the file in a lower case format
$ext = getExtension($filename);
$ext = strtolower($ext);
if(in_array($ext,$valid_formats))
{
if ($size < (MAX_SIZE*1024))
{
$image_name=time().$filename;
$newname=$uploaddir.$image_name;
if (move_uploaded_file($_FILES['photos']['tmp_name'][$name], $newname))
{
$mysqli->query("INSERT INTO galleries(image) VALUES('$image_name')");
echo "Image uploaded";
}
else
{
echo '<span class="imgList">You have exceeded the size limit! so moving unsuccessful! </span>';
}
}
else
{
echo '<span class="imgList">You have exceeded the size limit!</span>';
}
}
else
{
echo '<span class="imgList">Unknown extension!</span>';
}
}
}
?>
Any help will be appropriated.

You can implement a counter and when an upload completes successfully you can increment that counter variable then compare it against total number of array items after foreach loop completes. I modified your code for this (haven't checked it but should work).
<?php
error_reporting(0);
session_start();
include('db.php');
$id = $mysqli->escape_string($_GET['id']);
define ("MAX_SIZE","9000");
function getExtension($str)
{
$i = strrpos($str,".");
if (!$i) { return ""; }
$l = strlen($str) - $i;
$ext = substr($str,$i+1,$l);
return $ext;
}
$valid_formats = array("jpg", "png", "gif", "jpeg");
if(isset($_POST) and $_SERVER['REQUEST_METHOD'] == "POST")
{
$uploaddir = "gallery/"; //a directory inside
$successfulUploads = 0;
foreach ($_FILES['photos']['name'] as $name => $value)
{
$filename = stripslashes($_FILES['photos']['name'][$name]);
$size=filesize($_FILES['photos']['tmp_name'][$name]);
//get the extension of the file in a lower case format
$ext = getExtension($filename);
$ext = strtolower($ext);
if(in_array($ext,$valid_formats)) {
if ($size < (MAX_SIZE*1024)) {
$image_name=time().$filename;
$newname=$uploaddir.$image_name;
if (move_uploaded_file($_FILES['photos']['tmp_name'][$name], $newname)) {
$mysqli->query("INSERT INTO galleries(image) VALUES('$image_name')");
//echo "Image uploaded";
$successfulUploads = $successfulUploads + 1;
} else {
echo '<span class="imgList">Moving unsuccessful! </span>';
}
} else {
echo '<span class="imgList">You have exceeded the size limit!</span>';
}
} else {
echo '<span class="imgList">Unknown extension!</span>';
}
}
if($successfulUploads === count($_FILES['photos'])){
echo 'UPLOAD SUCCESS!';
} else {
echo 'NOT ALL IMAGES WERE UPLOADED SUCCESSFULLY';
}
}
*If you wanted to get more complex with it you could create another array variable instead of a counter and if the upload fails you could add the file name to the array and then check the length of the array where I'm doing the comparison. If count > 0 then you would know there was an error and you could echo the filenames that failed to upload
