resizing photo before move

moraru

i have tried to resize a photo from 640x480 to 320x240 while uploading it... but I have failed, here is the uploading script:

if ($POST['upload'] == "2"){
$poza = $FILES['poza']['tmp_name'];
if ($poza != ""){
$tip = $FILES['poza']['type'];
$ext = substr($tip,0,5);
if ($ext == "image"){
$new_poza = "images/".$FILES['poza']['name'];
move_uploaded_file($poza,$new_poza);
}
}
}

How can I resize it before moving?

thanks

So you want to use the appropriate imagecreatefrom* function to read the uploaded file (e.g., [man]imagecreatefromjpeg[/man] depending on the type of the file ([man]getimagesize[/man] can tell you this), create a new 320x240 image with [man]imagecreate[/man], use [man]imagecopyresized[/man] or [man]imagecopyresampled[/man] to copy the loaded image into the new image, then use the appropriate function (e.g., [man]imagejpeg[/man]) to save it wherever you want the completed image to go.

no, I dont want read and modify the uploaded file, I want before moving the file to the server to check the size and if necesary resize and the upload the file to the server, so when reading the file wont be necesary to use any special function from php just <img src="myfile">

I think what Weedpacket suggested is about the best option you have. From what I understand, it's impossible to read file information such as size - and resize before the actual upload.

I have a nice little script written that dynamically resizes images upon request... this way, you can call the image of your choice by saying <img src="resize_img.php?yourImg.ext"> and you can write whatever text you want to the top left corner of the image and change the image size at will.

However, it's not resized before or during upload. The source image is never manipulated. It's located here: http://www.deadlysin3.net/FREE/gen_thumbnail/gen_thumb.phps - feel free to use it if you want.
