Help To Fix Image Resize To Save To Server

AdSpace · November 2, 2012

Hello all forum members:

I am new here and I need help!

I have a file that let the user upload a file to our server/script

it should resize and save the file to our server folder, but the final file saved is 0 bytes

I do have ImageMagik 6.8.0-4 installed on the server hosting

I will post the file code below for review

Thanks in advance to all

do you save the file in ftp or database?

do you save the file in ftp or database?

Web server user uploads the image, but anyways...

It looks like what you are trying to do is relying on system commands, couldn't you utilize any PHP based methods of image manipulation?

I mean it is using getimagesize(); so that indicates to me that the GD library is installed, unless the function is declared in another PHP file.

I never used ImageMagick so I might not be much help on that end.

GD is pretty easy though and can be written out in a few lines,

imagecreate() create new resized image

getimagesize() but you already have that one

imagecreatefromjpeg() open the uploaded jpeg file

imagecopyresampled() there is a lot of arguments to assign to this one:

(new image, source image, src_x, _y, dest_x, _y [so these would be 0 for this use], new_w, new_h, old_w, old_h)

imagejpeg()
