avatar upload sizes

[sopranolv]

in script i have this

$target_path2 = $_SERVER['DOCUMENT_ROOT']."/uploads/";
   $aname1 = basename( $_FILES['avatar']['name']);
   $anameExt = substr($aname1, 100);
   switch($anameExt)
   {
    case '.png':
      $papl = ".png";
    break;
    case '.gif':
      $papl = ".gif";
    break;
    default:
      $papl = ".jpg";
    break;
   }
   $failaName = time().$papl;
   $target_path = $target_path2 . $failaName; 
   move_uploaded_file($_FILES['avatar']['tmp_name'], $target_path);     
   $ext = createThumb($target_path, "uploads/avatars/avatar_$user[id]", 550, 950);
   $pictureURL = "/uploads/pictures/".$faila_nosaukums;
    $sizes = array(25, 46, 75, 100);
    foreach($sizes as $size)
    {
    createThumb($target_path, "uploads/avatars/avatar_$user[id]_".$size."x".$size, $size, $size);
	
    //chmod($_SERVER['DOCUMENT_ROOT']."/uploads/avatars/avatar_$user[id]_".$size."x".$size.$ext, 0777);
    //echo $_SERVER['DOCUMENT_ROOT']."/uploads/avatars/avatar_$user[id]_".$size."x".$size.$ext;
    }
  
   unlink($target_path);
   $avatar=quote_smart("/uploads/avatars/avatar_".$user[id].$ext);
  
}

in functions.php i have this

$row['avatar'] = $row['avatar'] == "default" ? site_url. "/style/images/avatar.png":site_url.$row['avatar'];
  $sizes = array(25, 46, 75, 100);
  foreach($sizes as $size)
  {
  if($row['avatar'] != site_url."/style/images/avatar.png")
  {
  $row['avatar_'.$size.'x'.$size] = str_replace("_$row[id]", "_$row[id]_".$size."x".$size, $row['avatar']);
  $row['avatar_'.$size.'x'.$size] = $row['avatar_'.$size.'x'.$size] . "?".filemtime($_SERVER['DOCUMENT_ROOT'].str_replace(site_url, '', $row['avatar_'.$size.'x'.$size]));
  }
  }
  if($row['avatar'] == site_url."/style/images/avatar.png")
  {
  foreach($sizes as $size)
  {
  $row['avatar_'.$size.'x'.$size] = $row['avatar'];
  }
  }
  else
  {
    $row['avatar'] .= "?".filemtime($_SERVER['DOCUMENT_ROOT'].str_replace(site_url, '', $row['avatar']));
  }
  
  return $row;
}

how make this script to upload orginal size image not only the thumbs ?

[Ch0cu3r]

The code already does upload the original size image. The script removes the original image when it has created all the thumbnails. To prevent it deleting the original image, remove  unlink($target_path);

ok thx work's fine and i have one more problem when I upload image turned 90 degrees why?

 

[Ch0cu3r]

Is that the thumbnail images? Can you show us the code for the createThumb function?

yes its thumbnail images

function userInfo($user = '0')
{
  if(is_numeric($user))
  {
  $user = $user == 0 ? (int)$_COOKIE['user_id']:$user;
  $query = mysql_query("SELECT * FROM users WHERE id = $user");
  }
  else
  {
  $user = quote_smart($user);
  $query = mysql_query("SELECT * FROM users WHERE username = $user");
  }
  $row = mysql_fetch_array($query);
  if((int)$row['id'] > 0)
  {
  $posts = get_post_count_author($row['id']);
  mysql_query("UPDATE users SET posts = $posts WHERE id = $row[id]");
  $row['posts'] = $posts;
  }
  $row['mgroup'] = (int)$row['mgroup'];
  $row['avatar'] = $row['avatar'] == "default" ? site_url. "/style/images/avatar.png":site_url.$row['avatar'];
  $sizes = array(25, 46, 75, 100);
  foreach($sizes as $size)
  {
  if($row['avatar'] != site_url."/style/images/avatar.png")
  {
  $row['avatar_'.$size.'x'.$size] = str_replace("_$row[id]", "_$row[id]_".$size."x".$size, $row['avatar']);
  $row['avatar_'.$size.'x'.$size] = $row['avatar_'.$size.'x'.$size] . "?".filemtime($_SERVER['DOCUMENT_ROOT'].str_replace(site_url, '', $row['avatar_'.$size.'x'.$size]));
  }
  }
  if($row['avatar'] == site_url."/style/images/avatar.png")
  {
  foreach($sizes as $size)
  {
  $row['avatar_'.$size.'x'.$size] = $row['avatar'];
  }
  }
  else
  {
    $row['avatar'] .= "?".filemtime($_SERVER['DOCUMENT_ROOT'].str_replace(site_url, '', $row['avatar']));
  }
  
  return $row;
}

Umm.. No you posted the code user_info() function. I asked for the code for createThumb() function

[sopranolv]

sorry

function createThumb($sourcefile, $target_file, $new_w, $new_h)
{
  $root = $_SERVER['DOCUMENT_ROOT']."/";
  $source_path = $sourcefile;

  //
  // Add file validation code here
  //

  list( $source_width, $source_height, $source_type ) = getimagesize( $source_path );

  switch ( $source_type )
  {
    case IMAGETYPE_GIF:
      $source_gdim = imagecreatefromgif( $source_path );
      $ext = ".gif";
      $fija = "imagegif";
      break;

    case IMAGETYPE_JPEG:
      $source_gdim = imagecreatefromjpeg( $source_path );
      $ext = ".jpg";
      $fija = "imagejpeg";
      break;

    case IMAGETYPE_PNG:
      $source_gdim = imagecreatefrompng( $source_path );
      $ext = ".png";
      $fija = "imagepng";
      break;
  }

  $source_aspect_ratio = $source_width / $source_height;
  $desired_aspect_ratio = $new_w / $new_h;

  if ( $source_aspect_ratio > $desired_aspect_ratio )
  {
    //
    // Triggered when source image is wider
    //
    $temp_height = $new_h;
    $temp_width = ( int ) ( $new_h * $source_aspect_ratio );
  }
  else
  {
    //
    // Triggered otherwise (i.e. source image is similar or taller)
    //
    $temp_width = $new_w;
    $temp_height = ( int ) ( $new_w / $source_aspect_ratio );
  }

  //
  // Resize the image into a temporary GD image
  //

  $temp_gdim = imagecreatetruecolor( $temp_width, $temp_height );
 imagealphablending($temp_gdim, false);
 imagesavealpha($temp_gdim,true);
 $transparent = imagecolorallocatealpha($temp_gdim, 255, 255, 255, 127);
 imagefilledrectangle($temp_gdim, 0, 0, $temp_width,$temp_height, $transparent);

  imagecopyresampled(
    $temp_gdim,
    $source_gdim,
    0, 0,
    0, 0,
    $temp_width, $temp_height,
    $source_width, $source_height
  );

  //
  // Copy cropped region from temporary image into the desired GD image
  //

  $x0 = ( $temp_width - $new_w ) / 2;
  $y0 = ( $temp_height - $new_h ) / 2;

  $desired_gdim = imagecreatetruecolor( $new_w, $new_h );
   imagealphablending($desired_gdim, false);
 imagesavealpha($desired_gdim,true);
 $transparent = imagecolorallocatealpha($desired_gdim, 255, 255, 255, 127);
 imagefilledrectangle($desired_gdim, 0, 0, $new_w,$new_h, $transparent);

    $desired_gdim,
    $temp_gdim,
    0, 0,
    $x0, $y0,
    $new_w, $new_h

  //
  // Render the image
  // Alternatively, you can save the image in file-system or database
  //
  
  
  if($fija($desired_gdim, $root.$target_file.$ext)) {

I have tested your function and I none of the images I used for re-sizing was rotated. How are you viewing the images?

[PaulRyan]

The image rotation issue, is usually to do with photos taken on a mobile device (iPhones are the main culprit).

 

I'm sure there is a way to detect if the image is rotated, let me get back to you on it.

yes i think it is problem becouse i try image from google upload That's ok and when i try upload image taken by my samsung,it rotated how fix it someone know?

[scootstah]

The EXIF data should contain an "Orientation" if the image is rotated. You can read this data and apply the necessary corrections.
