Profilepic in session, how to update?

[B_CooperA]

I know this might been asked before, but my problem is a bit different compared to the other related topic I found in here. So, I have a profile page where user can change his/her profile pic. Here's my function for that: 

public function createProfileThumb() {



if(!empty($_FILES['upload_profile_pic']['name'])) {

	$target_folder = 'images/thumbnails/'; // Tallennettava kansio
	$ext = pathinfo($_FILES['upload_profile_pic']['name'], PATHINFO_EXTENSION);
	$newimg_name = "userprofilepic".$_GET['id'].".".$ext;
	$upload_image = $target_folder.basename($_FILES['upload_profile_pic']['name']);

        // Uusi tiedostopaikka

	if(move_uploaded_file($_FILES['upload_profile_pic']['tmp_name'], $upload_image)) {

	$thumbnail = $target_folder.$newimg_name; // Thumbnailin nimi

	// Get new sizes
	list($width, $height) = getimagesize($upload_image);
	$newwidth = 300; // Thumbnailin leveys pikseleissä
	$newheight = 300; // Thumbnailin korkeus pikseleissä

		
        // Kuvan lataus
	$thumb = imagecreatetruecolor($newwidth, $newheight);

	if( $_FILES['upload_profile_pic']['type'] == "image/jpeg" && 
		$_FILES['upload_profile_pic']['size'] < 3000000) {

	$source = imagecreatefromjpeg($upload_image);
	imagecopyresized($thumb, $source, 0, 0, 0, 0, $newwidth, $newheight, $width, $height);
	imagejpeg($thumb, $thumbnail, 100);

	$query = "UPDATE users SET profilepic = :profilepic WHERE user_id = :user_id";
		$stmt = $this->connect->prepare($query);
		$stmt->execute(array(

		':profilepic' =>  $newimg_name,

		':user_id' => $_SESSION['user_id']

	));

		if($query) {

		// REGENERATE THE $_SESSION['profilepic'] SOMEHOW

} else {

	$this->error[] = "Kuvan tallennus epäonnistui";

}



} else {

	$this->error[] = "Kuva on väärässä muodossa (vain .jpg) tai liian suuri";

}
	// Poistetaan alkuperäinen kuva 
	unlink($upload_image);

	} else {

		return false;

	}

	} else {

		$this->error[] = "Kuvaa ei ole valittu";

	}

	return (count($this->error)) ? 0 : 1;

}

And here's a part of my login script which will save somer user information, including profilepic, in to sessions.

public function fetchInfo() {

	$query = "SELECT * FROM users 
        WHERE email = :email AND  activation_token IS NULL";
	
        $stmt = $this->connect->prepare($query);
	$stmt->execute(array(

		':email' => $this->email,

		)); 

	if($stmt->rowCount() == 0) {
		$this->error[] = "Väärä käyttäjätunnus tai salasana";
		return 0;

	} else {

		$row = $stmt->fetch(PDO::FETCH_ASSOC);

		$_SESSION['user_id'] = $row['user_id'];
		$_SESSION['email'] = $row['email'];
		$_SESSION['name'] = $row['name'];
		$_SESSION['profilepic'] = $row['profilepic'];

	}

	if (Register::cryptPass($this->password) != $row['password']) {
	$this->error[] = "Virheelliset kirjautumistiedot";

	} else {

	return true;

	}
	return count($this->error) ? 0 : 1;

	}

My main problem is that every time user does change his/her profilepic, it will show up as a blank image until I log my self out destroying the session and log in back. So how will I some sort of "Regenerate" the picture inside the session superglobal?

 

My thumbnail function will obviously create a thumbnail from that uploaded picture, but also deletes the original picture and renames the new thumbnail to match up the users id. So if my users auto incremented user_id value in users table is 1, it will rename it to userprofilepic1.jpg. That will save me a lot of memory, since there's only one picture per user saved each and every time user changes the profile picture.

Just set the $_SESSION['profilepic'] to the new profilepic when the image has been uploaded.

$_SESSION['profilepic'] = $newimg_name;

Wow, didn't know it was that easy:D

 

Thanks a lot:)
