class image upload help

[corillo181]

i got a class that is supposed to make a resize image and a thumb.

 

the class

<?php
class img{
var $fileTmp;
var $fileSize;
var $fileName;
var $db;
var $save;
var $name;

function img($tmp,$name,$save){
	$this->fileTmp = $tmp;
$this->fileSize = $size;
$this->fileName = $name;
$this->save = $save;
$this->db = new DB();
}

function reName(){
	$ext = strtolower(substr(basename($this->fileName),-4));
$rand = mt_rand(0, 32);
$newName = md5($rand . time());
$this->name = $newName.$ext;

return $this->name;

}

function reSize($w,$h){
	$srcImg=imagecreatefromjpeg($this->fileTmp);
$thumbImg=imagecreatetruecolor($w,$h);
imagecopyresized($thumbImg,$srcImg,0,0,0,0,$w,$h,imagesx($srcImg),imagesy($srcImg));
imagejpeg($thumbImg,$this->save.$this->name,100);
return $this->save.$this->name;
}

function thumb($w,$h){
	$srcImg=imagecreatefromjpeg($this->fileTmp);
$thumbImg=imagecreatetruecolor($w,$h);
imagecopyresized($thumbImg,$srcImg,0,0,0,0,$w,$h,imagesx($srcImg),imagesy($srcImg));
imagejpeg($thumbImg,$this->save.'tn_'.$this->name,100);
return $this->save.'tn_'.$this->name;
  }
  
function insert($id,$thumb,$path){
	$query = "INSERT INTO artist_photo(artist_id,thumb_path,image_path,date)VALUES('$id','$thumb','$path',NOW())";
$this->db->query($query);

}
}
?>

 

the call

if(isset($_POST['addimg'])){

$save = $_SERVER['DOCUMENT_ROOT'].'/music/image/';
$tmpPath = $_FILES['fileMusic']['tmp_name'];
$fileName= $_FILES['fileMusic']['name'];
$artist_id = $_POST['artist'];

$img = new img($tmpPath,$fileName,$save);

$img->reName();
$path = $img->reSize(230,310);
$thumb = $img->thumb(100,75);
$img->insert($artist_id,$thumb,$path);
}

 

i get these errors

i narrow down the problem i seens that i am not getting anything from the tmp_name

<form action="" method="post" enctype="multipart/form-data" name="form1">
  <table width="100%" border="1">
    <tr>
      <td>artist</td>
      <td><label>
        <select name="artist" id="artist">
<?=$search->artistNames()?>
        </select>
      </label></td>
    </tr>
    <tr>
      <td>image file</td>
      <td><label>
        <input type="file" name="fileimg" id="fileMusic">
      </label></td>
    </tr>
    <tr>
      <td><input name="addimg" type="hidden" id="addimg" value="true" /></td>
      <td><button type="submit" name="submit" id="submit">Upload</button></td>
    </tr>
  </table>
</form>

 

i don't understand why is not getting the tmp file.
