Warning! Undefined variable Options

[tudsy]

Hi

I am getting a warning for an undefined variable. The program works but I get a warning that there is an undefined variable in the program.

mywriting.php ->form.php

error_log file is attached.


Thanks.

CODE

if(isset($_POST['Book'],$_POST['Price'])){
    
    
$book = $_POST['Book'];
$Price = $_POST['Price'];

}

The above means the variables are not set if the form page is loaded without a previous form submission:

CODE

<title>Order Form for <?php echo $_POST['Book']; ?></title>
...
<h1> Order form for <?php echo $_POST['Book']; ?> at (AUD)  $  <?php echo $_POST['Price']; ?> </h1>

(As a sidenote, there's no sanitation of the above POST data. Possibly a malicious user could inject unwanted code in your PHP script that way, like manipulating the price.)
