[RESOLVED] View tmp image?

[4rxsid]

Hello all,

Is it possible to view (like a preview) an image that a user uploads before it gets stored on a server (in db or filesystem)?

In other words, i'd like to be able to give the user a preview of their image (along with other data uploaded) before they actually "submit" this image to be stored. I'd like to stay away from having to write it to a temp directory, then deal with moving it or deleting it depending on the situation.

here's a bit of what i've tried (but it doesn't work of course), where $photo is the uploaded file:

          if ($photo != "") {

                $photoSize=GetImageSize($photo);
	  		      if ($photoSize[2]=="1") {
	  		         $tempPhoto=$photo.".gif";
	  		         rename ($photo,$tempPhoto);
	  		      } elseif ($photoSize[2]=="2") {
	  		         $tempPhoto=$photo.".jpg";
	  		         rename ($photo,$tempPhoto);
	  		      } elseif ($photoSize[2]=="3") {
	  		         $tempPhoto=$photo.".png";
	  		         rename ($photo,$tempPhoto);
	  		      }
          chmod($tempPhoto,0755);


          echo "<img src=\"$tempPhoto\" border=\"0\">";

any ideas?

Thanks.

Actually, you're using temp file-storage once the user uploads it. You can always open the $_FILES[] array and view output the image back into the browser, but you'd still need a temp image. I'm thinking that you can't do it without a temp image.

When you initially upload the image, it gets put in a temp area anyway so that PHP can work with it. So really, you're not doing any harm by accessing that image.

If someone else can prove me wrong, please do so. I'm up for a learning experience...

Thanks for the reply bpat.

yup, i knew that it was already placed in \tmp\phpxxxxxxx until it's modified and/or saved somewhere else. i just don't know how to get the \tmp\phpxxxxx temporary image to be displayed back on their browser.

if anyone knows how to get that tmp image (viewable image, not it's 'properties') back to the browser i would appreciate some pointers. i'm up for learning as well.

thanks!

You'll need to move or copy the uploaded file somewhere else (a sort of staging area) if you want to do that; files uploaded in the /tmp directory are deleted once the script that received them finishes.

After that, of course, the responsibility for deleting the file if it is unwanted becomes yours (or, rather, your program's).
