I have an upload script where I want to remove part of the code and make the rest of it still work, meaning make it dynamic. Can someone have a look and see if the upload part at the bottom could be removed but still have it do exactly it's function w/out the upload form.

<?php

if(isset($_POST['submit']))

{		

//make sure this directory is writable!

$path_thumbs = "../scripts/machform/data/form_1/files/";		

//the new width of the resized image, in pixels.

$img_thumb_width = 500; // 

$extlimit = "yes"; //Limit allowed extensions? (no for all extensions allowed)

//List of allowed extensions if extlimit = yes

$limitedext = array(".gif",".jpg",".png",".jpeg",".bmp");		

//the image -> variables

$file_type = $_FILES['vImage']['type'];

$file_name = $_FILES['vImage']['name'];

$file_size = $_FILES['vImage']['size'];

$file_tmp = $_FILES['vImage']['tmp_name'];

//check if you have selected a file.

if(!is_uploaded_file($file_tmp)){

echo "Error: Please select a file to upload!. <br>--<a href=\"$_SERVER[PHP_SELF]\">back</a>";

exit(); //exit the script and don't process the rest of it!

}

//check the file's extension

$ext = strrchr($file_name,'.');

$ext = strtolower($ext);

//uh-oh! the file extension is not allowed!

if (($extlimit == "yes") && (!in_array($ext,$limitedext))) {

echo "Wrong file extension.  <br>--<a href=\"$_SERVER[PHP_SELF]\">back</a>";

exit();

}

//so, whats the file's extension?

$getExt = explode ('.', $file_name);

$file_ext = $getExt[count($getExt)-1];

//create a random file name

$rand_name = md5(time());

$rand_name= rand(0,999999999);

//the new width variable

$ThumbWidth = $img_thumb_width;



/////////////////////////////////

// CREATE THE THUMBNAIL //

////////////////////////////////



//keep image type

if($file_size){

if($file_type == "image/pjpeg" || $file_type == "image/jpeg"){

$new_img = imagecreatefromjpeg($file_tmp);

}elseif($file_type == "image/x-png" || $file_type == "image/png"){

$new_img = imagecreatefrompng($file_tmp);

}elseif($file_type == "image/gif"){

$new_img = imagecreatefromgif($file_tmp);

}

//list the width and height and keep the height ratio.

list($width, $height) = getimagesize($file_tmp);

//calculate the image ratio

$imgratio=$width/$height;

if ($imgratio>1){

$newwidth = $ThumbWidth;

$newheight = $ThumbWidth/$imgratio;

}else{

$newheight = $ThumbWidth;

$newwidth = $ThumbWidth*$imgratio;

}

//function for resize image.

if (function_exists(imagecreatetruecolor)){

$resized_img = imagecreatetruecolor($newwidth,$newheight);

}else{

die("Error: Please make sure you have GD library ver 2+");

}

//the resizing is going on here!

imagecopyresized($resized_img, $new_img, 0, 0, 0, 0, $newwidth, $newheight, $width, $height);

//finally, save the image

ImageJpeg ($resized_img,"$path_thumbs/$rand_name.$file_ext");

ImageDestroy ($resized_img);

ImageDestroy ($new_img);





}



//ok copy the finished file to the thumbnail directory

move_uploaded_file ($file_tmp, "$path_big/$rand_name.$file_ext");

/*

Don't want to copy it to a separate directory?

Want to just display the image to the user?

Follow the following steps:



2. Uncomment this code:

/*

/* UNCOMMENT THIS IF YOU WANT */

//echo "IMG:<img src=\"$path_big/$rand_name.$file_ext\" />";

//exit();

//*/



//and you should be set!



//success message, redirect to main page.		

$msg = urlencode("Image was successfully uploaded! <a href=\"resize.php\">Upload More?</a>");

header("Location: resize.php?msg=$msg");

exit();





}else{



//if there is a message, display it

if(isset($_GET['msg']))

{

//but decode it first!

echo "<p>".urldecode($_GET['msg'])."</p>";

}

//the upload form

echo "

<form action=\"$_SERVER[PHP_SELF]\" method=\"post\"enctype=\"multipart/form-data\">\n

<p>File:<input type=\"file\" name=\"vImage\" /></p>\n

<p><input type=\"submit\" name=\"submit\" value=\"Submit\" /></p>";

}

?>

Thanks in advance

How will you upload the file without the form?

Easy way to test it simply comment that line out and see if it works. Do not comment out the closing }

PHP Code:

//echo "<form action=\"$_SERVER[PHP_SELF]\" method=\"post\"enctype=\"multipart/form-data\">\n
<p>File:<input type=\"file\" name=\"vImage\" /></p>\n
<p><input type=\"submit\" name=\"submit\" value=\"Submit\" /></p>"; 


For some reason VB is treating it like seperate lines of code when it is all one big echo statement.

The purpose of this would be to resize the images that already exist in a folder on my server instead of using the upload form to get the images. This script is *PERFECT* for that, but it contains an upload form that I don't need because I am already using a form to upload the images, and figured to do dynamic resizing from this script I posted above.
