[PHP] SimpleXML
Hi,
I am trying to write a PHP interface to ISBNdb.com. When I make a certain
request, the following is returned
Language, Proof and Logic
Jon Barwise, John Etchemendy,
Center for
the Study of Language and Inf
Amazon.com --
Nonfiction -- Philosophy -- Logic & Language
Amazon.com -- Science
-- General
And when loaded using simplexml_load_string, it gives the following object
object(SimpleXMLElement)#10 (2) {
["@attributes"]=>
array(1) {
["server_time"]=>
string(20) "2009-02-24T18:57:31Z"
}
["BookList"]=>
object(SimpleXMLElement)#14 (2) {
["@attributes"]=>
array(4) {
["total_results"]=>
string(1) "1"
["page_size"]=>
string(2) "10"
["page_number"]=>
string(1) "1"
["shown_results"]=>
string(1) "1"
}
["BookData"]=>
object(SimpleXMLElement)#11 (6) {
["@attributes"]=>
array(3) {
["book_id"]=>
string(24) "language_proof_and_logic"
["isbn"]=>
string(10) "157586374X"
["isbn13"]=>
string(13) "9781575863740"
}
["Title"]=>
string(25) "Language, Proof and Logic"
["TitleLong"]=>
object(SimpleXMLElement)#15 (0) {
}
["AuthorsText"]=>
string(30) "Jon Barwise, John Etchemendy, "
["PublisherText"]=>
string(40) "Center for the Study of Language and Inf"
["Subjects"]=>
object(SimpleXMLElement)#16 (1) {
["Subject"]=>
array(2) {
[0]=>
string(58) "Amazon.com -- Nonfiction -- Philosophy -- Logic &
Language"
[1]=>
string(32) "Amazon.com -- Science -- General"
}
}
}
}
Notice that I lose the attribute subject_id from the Subject tag. Why is
this?? Is there any way from preventing it from happening??
Thanks in advance,
Alex Chamberlain

Designed to be easy going, it is suppose to be ready to use out of the box, with very little config and a usable user management system - unlike Zend's Auth and ACL.

Problem solved:
function __autoload($c) {
$m = array();
preg_match('/(?:^[A-Z][a-z]+)Controller/', $c, $m);
if (count($m)) {
require_once(realpath(FS_CONTROLLER . '/' . strtolower($m[0]) .
'.inc.php'));
}
}
However (perhaps a more appropriate question), do you think there is an
easier/better way to do this??

Hi, I don’t understand regular expressions at all – I will make an effort to learn about them one day, but I need a solution today. I want to use the __autoload function, but not for all my class only those that finish in ‘Controller’. So for instance, ‘ErrorController’ should load ‘errorcontroller.inc.php’ ‘IndexController’ should load ‘indexcontroller.inc.php’ ‘FooBar’ should NOT load anything whatsoever. Can you help me write an __autoload function please?? Alex No virus found in this outgoing message.

RE: [PHP] Re: BarcodeDB.com - a Barcode Database
Thanks for your suggestion!! Sounds like a good route to go down with the API access. Really struggling with the pending 'list' at the moment. Suppose I have got 2 tables `product` and `description`. `product` contains `EAN`, `name`, `last_modified` and `description` contains `EAN` and `description`. The nearest thing to me right now is a tub of pencils. EAN: 5011772007888 Name: 50 Staedtler HB Pencils Description: A tub of 50 HB Pencils by Staedtler. Suppose someone at BarcodeDB.com, having signed in, wanted to change the description to: A tub of 50 HB Pencils by Staedtler. With strong break resistant leads, they make an ideal pencil for kids or adults alike. Rather than update this description straight into the database. It would be nice for it to wait to be approved, and once approved a 'history' is kept so it is known who submitted the data and who approved it. Any ideas on how to achieve this effectively??

[PHP] BarcodeDB.com - a Barcode Database
Hi, I am looking to set up a new 'public' database for barcodes. There are a couple of barcode databases out there, namely http://www.upcdatabase.com/ and http//en.barcodepedia.com/. UPC Database is old fashioned and over run by Google ads, but does provide an (unsecure) XML-RPC interface. Barcodepedia is more modern, but there is no XML-RPC. UPC Database has ~2 users and 977,498 barcode entries, but there is simply a barcode and a name (sometimes a size/ weight) - no description. Both sites claim to use the Creative Commons Attribution-Noncommercial-Share Alike 3.0 Unported License. I wish to set up a similar website. Indexed on the modern EAN-13 (used across the world, and includes ISBNs), the database will store a barcode and name for *every* product. Additionally, the description of the product can be stored. In the future, I would like to implement a 'tag-type' system, whereby a tag, consisting of name (eg Author) and value (eg JK Rowling), can be assigned to one or more objects. These tags could include links to publicly available images etc. The country of registration of each product can be derived from the barcode itself. I want to set up XML-RPC access for both downloading and uploading products, but I want them to be secure. When people upload or edit a product, I want it to go onto a pending list for me (and others in the future with the appropriate rights) to approve, unless it’s the manufacturer themselves. I know a very basic database is easy to setup - I did it in a day or two, but I am struggling with the user management side, including the authentication of API access, as well as how to implement a 'pending' list. Has anybody got any ideas?? Is there any (free) software out there capable of this?? If anybody else wishes to contribute to this very young project, I am open to ideas ([EMAIL PROTECTED]). Hosting is sorted and I own BarcodeDB.com and .co.uk Platform: PHP 5, ADOdb, Smarty - MySQL to start with, though I have thought about an XML database as well. As the platform develops, I want to let companies upload their products for free, but charge others to download them - think how much time companies spend on data entry for this kind of thing!! For the consumer, a money diary etc will follow. Thanks, Alex No virus found in this outgoing message.

[PHP] Image Generation
Hi, I need to generate an online proof for vinyl lettering. Customers specify the text, font, colour, maximum frame size (mm) (ie the width and height it must fit into), and whether or not they want to keep aspect ratio (ie not distort the lettering). I want to represent all this on a single image. So it would display a border with their width and height on, and inside this would be the text in the appropriate colour and font – if they decide to keep aspect ratio the text would not be distorted. If they do not, it would be. The image would always be 300px wide by 150px high (these would need to be constants that I could change from time to time). I’ve got a very basic proof working using a GD wrapper, but I don’t think GD is powerful enough to do it all, nor do I recon my programming skills are up for it. Has anybody got any advice on how to tackle this, even if it is just bits of the problem?? Thanks, Alex Chamberlain No virus found in this outgoing message.

Alex Hello Alex, I was reading through this thread, and I was curious about what methods you use to handle fractions of a dollar and/or fractions of a penny if you are always using integers. Do you only use a decimal for printing? do you adjust all interest rates, etc...then as well? How about when interest calculations result in fractions of pennies, how do you handle it then? Basically, I can't see how it could be done with just integers alone? thanks dank [/quote] To be honest, I haven't used it for any complicated use - shopping carts are additive contraptions. However, I don't see the problem. 1) I use Smarty a lot - I use a plugin to format the integer to a price (ie divide by 100 and display in 2 decimal places). So yes, I only put the decimal place there to print. 2) Why do interest rates need to be changed?? Take £123.45 @ 5%. 123.45 * 1.05 = (12345 [pennies] / 100) [pounds] * 1.05 = (12345 * 1.05) / 100 Same calculation in my mind!! (Tell me if I have missed the point!!) 3) If you have a fraction of a penny - round it!! Surely, that's what the banks do!! It's a penny!! I think it can be done with integers alone - let me know if you disagree!! Alex No virus found in this outgoing message.

I don't quite understand your problem, but I use integers for any monetary
workings as you can guarantee it is accurate (obviously, you work in pence
or cents rather than GBP or USD).

In fact, I started a few weeks ago looking at the OpenID specification, and a PHP server implementation: I found it to be confusing and quite buggy. I hope to implement a OpenID 'frontend' in the future, but not straight away. I also consulted several friends, as well as some of my 18-year-old brothers friends - although a few were very comfortable with the internet and did understand, a lot were confused by the concept of a URL itself - they sort of understood when I explained it was a web address, but could not understand how to use this as a username: this is a fundamental problem of their discovery procedure, in my opinion. Also, a single server system will be more consistent and more secure, and I hope the sharing of personal information *legally* will be a key attraction for most websites. I am at a very early stage, and welcome any comments. Alex No virus found in this outgoing message.

Ahh, but they are on different webservers
At the moment, I am just using a query string. How long is the limit of the
query string??
