php - move_uploaded_file not working after preview page -


i'm submitting form preview page(form) , final submit. i'm having trouble getting move_uploaded_file work. how solve this? when check directory there no file there.

preview page 

      $tmpname = $_files['titleimage']['tmp_name'];             $imagefile = $_files['titleimage']['name'];           $filename = basename($imagefile);            $imagename = dirname(__file__).'/avatar/'.$filename;               echo "<form enctype='multipart/form-data' id='submitpreview' action='/upload' method='post'> <input type='hidden'  name='image' value='$tmpname' readonly />     <input type='hidden'  name='imagedir' value='$imagename' readonly />";                         //other code                 echo "<div id='preview-submit-button'><a>submit</a></div>                 </form>";

upload page

$image = $_post['image']; $directory = $_post['imagedir'];  move_uploaded_file($image,$directory);

are sure temporary file $_files['titleimage']['tmp_name'] still there after submit second form? remember, it's temporary file. i'm afraid lives time first form submitted (just until request processed).

so, should:

  1. as possible (that means, in page receive first form, preview page in fact) save temporary file in folder of yours using move_uploaded_file().

  2. if user confirms preview, move file directory saved in step 1 definitive folder, using rename() function.

  3. if user does not confirm preview, delete using unlink() function.

additionaly, marc b pointed out, should have security of preview-save logic. passing paths , filenames in hidden form field way hackers break system. have @ php sessions (maybe know), , consider moving paths public form session variable.
