Editing a Gallery app....

i have a form i am currently using to allow for an upload and watermark of an image,

I want to include a batch feature which has been going well so far

Id like to use exactly the same process in my form but i cant use it because it uses the $file_[upload] i dont know how to change this part so it opens all my files, instead of the .zip,

the watermark from a single file script is...

<?php

ob_start();

$disp_width_max=150; // used when displaying watermark choices

$disp_height_max=80; // used when displaying watermark choices

$edgePadding=0; // used when placing the watermark near an edge

$quality=100; // used when generating the final image

$default_watermark='Sample-trans.png'; // the default image to use if no watermark was chosen

if(isset($_POST['process'])){

// an image has been posted, let's get to the nitty-gritty

if(isset($_FILES['watermarkee']) && $_FILES['watermarkee']['error']==0){

// be sure that the other options we need have some kind of value

if(!isset($_POST['save_as'])) $_POST['save_as']='jpeg';

if(!isset($_POST['v_position'])) $_POST['v_position']='bottom';

if(!isset($_POST['h_position'])) $_POST['h_position']='right';

if(!isset($_POST['wm_size'])) $_POST['wm_size']='1';

if(!isset($_POST['watermark'])) $_POST['']=$default_watermark;

// file upload success

$size=getimagesize($_FILES['watermarkee']['tmp_name']);

if($size[2]==2 || $size[2]==3){

// it was a JPEG or PNG image, so we're OK so far

$original=$_FILES['watermarkee']['tmp_name'];

$target_name=date('YmdHis').'_'.

// if you change this regex, be sure to change it in generated-images.php:26

preg_replace('`[^a-z0-9-_.]`i','',$_FILES['watermarkee']['name']);

$target=dirname(__FILE__).'/results/'.$target_name;

$watermark=dirname(__FILE__).'/watermarks/'.$_POST['watermark'];

$wmTarget=$watermark.'.tmp';

$origInfo = getimagesize($original);

$origWidth = $origInfo[0];

$origHeight = $origInfo[1];

$waterMarkInfo = getimagesize($watermark);

$waterMarkWidth = $waterMarkInfo[0];

$waterMarkHeight = $waterMarkInfo[1];

// watermark sizing info

if($_POST['wm_size']=='larger'){

$placementX=0;

$placementY=0;

$_POST['h_position']='center';

$_POST['v_position']='center';

$waterMarkDestWidth=$waterMarkWidth;

$waterMarkDestHeight=$waterMarkHeight;

// both of the watermark dimensions need to be 5% more than the original image...

// adjust width first.

if($waterMarkWidth > $origWidth*1.05 && $waterMarkHeight > $origHeight*1.05){

// both are already larger than the original by at least 5%...

// we need to make the watermark *smaller* for this one.

// where is the largest difference?

$wdiff=$waterMarkDestWidth - $origWidth;

}else{

// the watermark will need to be enlarged for this one

// where is the largest difference?

$wdiff=$origWidth - $waterMarkDestWidth;

$hdiff=$origHeight - $waterMarkDestHeight;

if($wdiff > $hdiff){

// the width has the largest difference - get percentage

$sizer=($wdiff/$waterMarkDestWidth)+0.05;

}else{

$sizer=($hdiff/$waterMarkDestHeight)+0.05;

}

$waterMarkDestWidth+=$waterMarkDestWidth * $sizer;

But i want to change it so it batch process all of the zip file contents i have an unzip script which looks like this..

this unzip also shows the contents of the unzip when decompressed anyone know how i can rid myself of the zip file too?

im guessiing unlink() but i dont quite know where to stick it.

<?php

$new_name = "batch.zip";

//Check MIME Type

if (in_array($_FILES['upload']['type'], $types)){

move_uploaded_file($tmp_name,$dir . $new_name);
