[Chapter 4: Register.php]

Thanks for the insight. Yes...there was an error in the code in $q, I accidently placed a single quote before username in the query which I didn't in the question I sent to you. Thanks very much.

[Chapter 4: Register.php]

I'm getting an error that says parameter 1 of mysqli_num_rows($r) should be a mysqli_result, Boolean given. Here is the applicable code:

 

$q = "SELECT email, username FROM users WHERE email='$e' OR username='$u'";

$r = mysqli_query($dbc,$q);

$rows = mysqli_num_rows($r); //This is where the error occurs.

 

Help would greatly be appreciated! Thank you.

[Chapter 19: Checkout.php]

The orders are processing, but the order_contents are not.

[Chapter 19: Checkout.php]

Hi. I'm having a problem with the code in checkout.php in Chapter 19.

For some reason, I get the following errors:

 

Notice: Undefined index: cart in C:\xampp\htdocs\php\PHPandMySQL\ch19\checkout.php on line 26.

 

Warning: Invalid argument supplied for foreach() in C;\xampp\htdocs\php\PHPandMySQL\ch19\checkout.php on line 26.

 

Notice: Undefined index: cart in C;\xampp\htdocs\php\PHPandMySQL\ch19\checkout.php on line 37.

 

I have included the header.html file. This starts the session. So the session variable is set. Here is my code for the foreach function on line 26:

 

foreach($_SESSION['cart'] as $pid => $item) {

...

}

 

Here is the if conditional for line 37:

 

if($affected == count($_SESSION['cart'])) {

...

}

 

Why am I getting these notices and warnings? The code appears correct.

[Script_17_4.php]

Can't get the dates to show up when I call up forum.php. The code I downloaded from your site doesn't work either. Could it be that the variables $first and $last are local to the if?

That was the problem, Larry. Thanks. Why does that happen when you use the 'run' function in notepad++?
