Undefined index: file

Hi I’m learning right now how to upload images to database, but I’m getting this error/notice

Notice: Undefined index: image in C:\xampp\htdocs\Pildibaas\index.php on line 19

Here is my index.php whole code:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>Image upload</title>
</head>

<body>
    <form action="index.php" method="POST" enctype="multipart/form-data">
        File:
        <input type="file" name="image"> <input type="submit" value="Upload"> 
    </form>


<?php
mysql_connect ("localhost", "root", "") or die (mysql_error());
mysql_select_db ("databaseimage") or die (mysql_error());


?>
</body>

</html>

Line 19 (this line gives error) cut out from index.php:

echo $file = $_FILES['image']['tmp_name'];

From google found that i need to change premission of tmp folder, but it allready shoud have all premissions it needs.

    echo $file = $_FILES['image']['tmp_name'];

    should be

    if(isset($_FILES['image'])){
    echo $_FILES['image']['tmp_name'];
}

    This checks first if $_FILES['image'] is set. If not, this wil not be run. Therefore, you will not have an error that it is out of index.

    Because you first have to submit the form before $_FILES['image'] will be set…

    Also, the input tag is self closing, so your form will not be:

    <form action="index.php" method="POST" enctype="multipart/form-data">
    File:
    <input type="file" name="image"> <input type="submit" value="Upload"> 
</form>

    but:

    <form action="index.php" method="POST" enctype="multipart/form-data">
    File:
    <input type="file" name="image" /> <input type="submit" value="Upload" /> 
</form>
