PHP image upload and resize error_问答_开发者_运维开发者技术经验分享

I looked the site to find a solution for my problem, but couldn't find the answer. Hopefully someone can help me with this:

I have a script that uploads and resizes an image without pagerefresh. I found it on the internet and adjusted it for my use. The script can be found underneath.

My problem:

First the upload.p开发者_运维知识库hp script worked, but know I get error number 9.

What did I do to try to solve it myself:

Tried it on a localmachine and on a server, both give the same error number 9
Removed all the $_POST and set 'static' vars, didn't work and still got number 9

Can someone please help me, tnx in advance

Grtzzz

Try to remove the @ in this line:

 if(!@imagejpeg($im,$dir.$file,100)){

It suppresses the error imagejpeg throws. Without it, you might see what your problem is.

Remove @ from the following line:

  if(!@imagejpeg($im,$dir.$file,100)){

@ suppresses errors. If it's removed and display_errors is on, you should see a more descriptive error message.

My guess is that imagejpeg() can't write to the file because of insufficient permissions.

Damn,

I'm stupid :(

As suggested I removed the @ and saw with my own eyes what I've done wrong.

The error was in my directory structure it is like this

The $dir = $_POST['uploadPath']; was a folder that moved the files to "mainfolder/subfolder/imageFolder" but it needed to be "imageFolder/" because I use the upload.php file in the "subfolder".

Thx for all your help

Grtz
