Upload file (image) function

Site Admin Joined: Aug 22, 2007 Posts: 1775

I search a simple upload method for saving images/avatars (jpg, gif and png) with a function in RN. I have variables with the filename and the filepath but i don't get it realized. I play with an code-snippet from an old file and try it to run in a update function.

Code:

$id = '1';   


$postavatar = 'file.jpg';


$myfilepath = 'path/to/my/folder/';





function upload($id, $postavatar, $myfilepath) {


global $prefix, $db;


   if (stripos($_FILES['postavatar']['type'],'image')!==false) {


      $size = getimagesize($_FILES['postavatar']['tmp_name']);


      if($size[0]==120 && $size[1]==120) {                     


         $avatarfile = rand(1000,9999).$_FILES['postavatar']['name'];


         $avatarfile = $db->sql_escape_string($avatarfile);


         $query = $db->sql_query('UPDATE ' .$prefix . '_myusers SET '."avatar='$avatarfile'".' WHERE id = \'' . $id . '\'');


         if(!move_uploaded_file($_FILES['postavatar']['tmp_name'],$myfilepath.$avatarfile)) {


            echo "fail";


         } else {


            echo "done";


         }


      }


   }


}

...any ideas?

What exactly is the problem? Have you narrowed it down to anything? Have you tried var_dump() on $_FILES to see if the file name etc is there?

I have got it sorted! I must check if "isset($_FILES['postavatar'])" and assign to the variable $postavatar.
