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:

<form action="<?php echo $_SERVER['PHP_SELF'];?>" method="POST"> <input type="hidden" name="rowID" value="<?php echo $rowID;?>"> <p> Product ID:<br /> <input type="text" name="productid" size="8" maxlength="8" value="<?php echo $productid;?>" /> </p> <p> Name:<br /> <input type="text" name="name" size="25" maxlength="25" value="<?php echo $name;?>" /> </p> <p> Price:<br /> <input type="text" name="price" size="6" maxlength="6" value="<?php echo $price;?>" /> </p> <p> Description:<br /> <textarea name="description" rows="5" cols="30"> <?php echo $description;?></textarea> </p> <p> <input type="submit" name="submit" value="Submit!" /> </p> </form> <?php if (isset($_POST['submit'])) { $rowID = $_POST['rowID']; $productid = $_POST['productid']; //this is line 32 and so on... $name = $_POST['name']; $price = $_POST['price']; $description = $_POST['description']; } 

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 aren't.

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