Resizing images.

[Chelsea7]

Hi I have a question about resizing images and uploading them to a server. The code below works. However, it also copies the original file to the root directory. I only want the thumb nails files uploaded in a directory call 'upload', which it already does. But the original file is going to the root directory, after the user clicks the submit button on the form.

<?php

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

{


$path_thumbs = "/upload/";

$img_thumb_width = 400; //

$extlimit = "yes";

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

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

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

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

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

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!

}

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

$ext = strtolower($ext);

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

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

exit();

}

$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 //

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



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


$imgratio=$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+");

}



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



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

ImageDestroy ($resized_img);

ImageDestroy ($new_img);


}



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



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

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

exit();





}else{


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

{

//but decode it first!

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

}


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>";

}



?>

Any assistance would be appreciated.

uploaded files should normally be stored in your tmp system directory where file perms should permit the php process to delete files itself on unload. i do not think it a good idea for php (or any external process) to have write access to your system root. check your php.ini and change the setting accordingly. remember to restart the web server afterwards.

I got it work. Yes, php process to delete the files itself. I have it pointing to the wrong directory.
