Ch10, P303, P304 Two Possible Typos

[Christopher]

Larry,

 

in CH10, P303:

 

$url = 'page.php?name=' . urlencode
➝ ('Elliott Smith');
You only need to do this when programmatically
adding values to a URL. When a form
uses the GET method, it automatically encodes
the data.

 

// Actually I think it should be the POST method, coz  unlike GET request, POST data does not need to be encoded or decoded.

 

 

P304:

 

In the preceding example, a new version
of the view_users.php script was written.
This one now includes links to the edit_
user.php and delete_user.php pages,
passing each a user’s ID through the URL.

 

// I think this 'a' is a typo here(not needed).

Yes, the second one is definitely a typo.

As for the first one, please see the following:

As for the first one, it should be GET. The point I'm trying to make is that when values end up in a URL through a form that uses GET, they're automatically URL-encoded. When you manually add values to a URL, you must URL-encode them yourself.
