Hey guys.

I have a page which posts images to itself.

The name on the <input type file> changes each time. Its in the format of 'Thumbnail#' eg. Thumbnail1 Thumbnail2 etc. This can only be up to Thumbnail28.

How can i work out which number was posted, and then use the number? There will always be 2. Eg if there is a thumbnail1 there will be a thumbnail 2 as thumbnails have to come in packs of 2.

Heres my current code.

<?php
session_start();
if ($_SESSION['adminlogin'] == 1){
	//Run
}
else {
header('Location: Log-In.php');
exit;
}
?>
  
<?php
$warnings = '<b>Errors:</b><br>';
//Data from Edit-Page.php first time
$Name = $_GET['name'];
$TypeOfEdit = $_GET['typeofedit'];
$LightType = $_GET['lighttype'];
$LightName = $_GET['lightname'];
$NumberOfThumbnailsRequired = $_GET['numberofthumbnails'];
$PageLocation = $_GET['pagelocation'];

//Data from this page second time
$Name = $_POST['Name'];
$TypeOfEdit = $_POST['TypeOfEdit'];
$LightType = $_POST['LightType'];
$LightName = $_POST['LightName'];
$PageLocation = $_POST['PageLocation'];

//Work out name of each thumb/large
$Thumbnailname = 'NameofThumbnail'; ###########################################################################################################################
$Largename = 'NameofLarge'; ###################################################################################################################################

//Work out location to move each thumb to & create it if need be

$target_path_thumbnails = '../Images/'.$LightType.'/'.$LightName.'/Mini';
$target_path_without_mini = '../Images/'.$LightType.'/'.$LightName;
$target_path_thumbnails_and_extension = $target_path_thumbnails.'/'.$Thumbnailname.'.png';

$target_path_large = '../Images/'.$LightType.'/'.$LightName.'/'.$Largename.'.jpg';

if (file_exists($target_path_thumbnails)) {
	//Do nothing.
} else {
	if (file_exists ($target_path_thumbnails_without_mini)) {
		mkdir($target_path_thumbnails,0777);
	} 
	else {
	mkdir($target_path_thumbnails_without_mini,0777);
	mkdir($target_path_thumbnails,0777);
	}
}	

//Move uploaded thumbnial to this location
if(move_uploaded_file($_FILES[$Thumbnailname]['tmp_name'], $target_path_thumbnails)) {
	$Thumbnailname = 'http://www.worldwidelighthouses.com/Images/'.$LightType.'/'.$LightName.'/'.$Thumbnailname.'.png';;
} 
else{
	$warnings = $warnings."There was an error uploading the thumbnail file, please try again!<br>";
	$Thumbnailname = "";
}
if(move_uploaded_file($_FILES[$Largename]['tmp_name'], $target_path_large)) {
	$Thumbnailname = 'http://www.worldwidelighthouses.com/Images/'.$LightType.'/'.$LightName.'/'.$Thumbnailname.'.png';;
} 
else{
	$warnings = $warnings."There was an error uploading the large image file, please try again!<br>";
	$Thumbnailname = "";
}	
if (!isset($NumberOfThumbnailsLeft)){$NumberOfThumbnailsLeft = $NumberOfThumbnailsRequired;}

$FirstThumbnailPostName = $NumberOfThumbnailsRequired - $NumberOfThumbnailsLeft + 1;
$SecondThumbnailName = $FirstThumbnailPostName + 1;
?>

Any or all help is appreciated.

An easy method would be to use arrays.

Print out $_FILES["thumbnail"] to see the array PHP generates. Then there's no arbitrary limit of the number of thumbnails and your code will be a fair bit simpler.
