Script per Ridimensionate, convertire e salvare in DB

[zampi91]

Ho provato a scrivere il programma ma mi viene dato un errore:

ovvero, file_get_contents($NewImg) vuole una stringa.

questo è il codice:

function upImg($File, $Size, $Op){
        if($Size > 2000000){
            throw new Exception("Massimo 2MB");
        }
        
        list($Width, $Height, $Ext) = getimagesize($File);        
        if($Ext != 1 && $Ext != 2 && $Ext != 3){
            throw new Exception("Formato supportato JPG, GIF e PNG");
        }        
        if($Ext == 2)        $ImgUp = @imagecreatefromjpeg($File); 
        elseif($Ext == 1)    $ImgUp = @imagecreatefromgif($File); 
        elseif($Ext == 3)    $ImgUp = @imagecreatefrompng($File); 
        
        $NewImg = imagecreatetruecolor(32, 32);
        
        imagecopyresized($NewImg, $ImgUp, 0, 0, 0, 0, 32, 32, $Width, $Height);    
        
        $NewImg = file_get_contents($NewImg);
        $Image = addslashes($NewImg);
        
        $Query = "UPDATE Users_Info INNER JOIN Users_Auth ON Users_Info.ID = Users_Auth.ID SET Users_Info.Avatar = '$Image' WHERE Users_Auth.NickName = '".$_SESSION["Confirm"]['NickName']."'";
        mysql_query($Query, $this->ConnUser)or die("Error!!!!");
    }
