I can't see the error

[system]

I’m new in php and I’m getting this error:

Notice: Undefined index: productid in /var/www/test/modifyform.php on line 32 Notice: Undefined index: name in /var/www/test/modifyform.php on line 33 Notice: Undefined index: price in /var/www/test/modifyform.php on line 34 Notice: Undefined index: description in /var/www/test/modifyform.php on line 35

I couldn’t find any solution online, so maybe someone can help me.

Here is the code:

[php]

Product ID:

Name:

Price:

Description:
<?php echo $description;?>

<?php if (isset($_POST['submit'])) { $rowID = $_POST['rowID']; $productid = $_POST['productid']; //this is line 32 and so on... $name = $_POST['name']; $price = $_POST['price']; $description = $_POST['description'];[/php]

What I do after that (or at least I’m trying) is to update a table in mysql.
I really can’t understand why $rowID is defined while the other variables don’t.

Thank you for taking your time to answer me.
Cheers!

Undefined index is just means that you’re trying to use a variable that hasn’t been created yet. Couple ways to fix it. 1 - before the section that uses them starts, default the varaibles to something, or 2 - use if(isset()) statements on each one. This can have some unintended side effects though.
