php/mysql programming problem - design - solution
suprise suprise, more problems with this book!!!
I'm starting to get somewhere but I'm still having loads of problems :-(
On inspecting the error_log of Apache, for every page request I get all these notices, which, I'm hazarding a guess isn't what's suppose to be happening!
Code:

What is an 'Undefined index' can't seem to find the answer easily on php.net (or with google) and why am I getting them ??? Also, I keep getting an error saying call to undefined function: isError() but PEAR is all setup, and my include_path is definately pointing at the PEAR dir, aaarrrrgggghhhhh!!
Anyone have a an idea what's going on here? ?? It would be nice, really nice, if the authors were around here as I'm sure they'd know exactly what was going on. I really don't want to go through the book without having the test site setup and working perfectly, it makes debugging my own work much harder.
Thanks as ever,
Jon

You're getting all of these errors because you have PHP set to display notice level errors. In a nut shell that means that if you use a variable without defining it first it'll throw a notice level error. That includes undefined array indices as well as undefined constants.
Have the error level set to E_ALL will include notice level errors. The benefits of this allows a more explicit execution of code and also has incredible benefits for the debugging process. PHP will tell you when you don't have a variable defined where you may want one defined.
You can get around these errors by writing your code more explicitly. By using basic constructs like isset() or empty().
Checks for a variable's existence without throwing a notice
http://www.php.net/isset
Checks for a variable's value without throwing a notice (there is a difference!) If true, empty checks for a false, null, zero or string zero value "0". If false it looks for the opposite. Whereas isset only looks for a variable's existence.
http://www.php.net/empty
This error:
[Tue Nov 18 11:08:04 2003] [error] PHP Notice: A session had already been started - ignoring session_start() in /Library/WebServer/Documents/wrox_site/_lib/_classes/class.session.php on line 68
You're getting because you are making a second call to session_start() somewhere in your script.
This error:
[Tue Nov 18 11:08:49 2003] [error] PHP Notice: Undefined index: id in /Library/WebServer/Documents/wrox_site/site/tpl_unsecure.php on line 10
Expects an array with associative indice "id" to already be set.
Also undefined offset will be the same thing but it will be talking about numeric indices.
And if you want to supress the notice level errors you can do so by changing the value of error_reporting in php.ini or at runtime with ini_set()
http://www.php.net/ini_set
Its helpful to have error reporting set to include notice level errors so I suggest getting accustomed to dealing with them with code rather than supressing them. Otherwise its not *really* going to hurt anything to supress them... that is unless the existence of the variable is crucial to the script's operation and supressing errors at that point would leave you in the dark.
You're getting these errors in a pear library?? That seems unusual to me. I would verify that you have all the necessary components. Perhaps you could let us know what library and how you are trying to use it with some code examples.

Here is a link that talks about the security benefits of error_reporting = E_ALL

I keep getting an error saying call to undefined function: isError()

Every pear library I've worked with is set-up as a class. Maybe you haven't properly instantiated the class?
Awaiting some code to speculate further!

HI Rich,
Ok, so these are more warnings than errors ?? but I'm guessing that all these missing vars will cause all sorts of problems ??? Is there any reason why I should be getting soo many errors from the source caode from this book ??? Seems a little crappy doesn't it, seeing as I haven't changed anything other than a few things in the config file, surely these vars should be passed by the scripts without any help from me. the entire site's source files can be found here <http://www.apress.com/ApressCorporate/supplement/1/200/159059150X-1182.zip> I know it's a well big ask to expect you to look through all the code without the book but it's worth a try!
Certain areas seem to work ok, others have strange bugs.
Code:
function accounts($iAccountId = '') {
// implement pear mail object
$this->_oMail =& Mail::factory("mail");
if (Mail::isError($this->_oMail)) { // this is line 58!
catchExc($this->_oMail->getMessage());
}
this relates to the error: PHP Fatal error: Call to undefined function: iserror() in /Library/WebServer/Documents/wrox_site/_lib/_classes/class.accounts.php on line 58
Any ideas ???

could it be that the PEAR class Mail.php hasn't been included ??? that would seem odd as there's nothing in the logs refering to an unknown file.

is there a simple way to test this outside of the main sites scripts ??? something like this ?
Code:
<?php
require_once("Mail.php");
require_once("DB.php");
var $_oMail;
$this->_oMail =& Mail::factory("mail");
if (Mail::isError($this->_oMail)) { // this is line 58!
echo($this->_oMail->getMessage());
}
?>
????

I get this error:
[cpde][Tue Nov 18 12:57:46 2003] [error] PHP Notice: Undefined variable: _oMail in /Library/WebServer/Documents/wrox_site/mail_test.php on line 10
[Tue Nov 18 12:57:46 2003] [error] PHP Fatal error: Call to undefined function: iserror() in /Library/WebServer/Documents/wrox_site/mail_test.php on line 15[/code]
with this script:
Code:
<?php
require_once("Mail.php");
require_once("DB.php");
function mailTest(){
echo "mailTest() called!";
$_oMail;
// implement pear mail object
$_oMail =& Mail::factory("mail");
if (Mail::isError($_oMail)) {
echo($_oMail->getMessage());
}
}
mailTest();
?>
but I don't get any errors regarding a missing include file, is this a PEAR problem!!!!! (sorry to kee banging on about it) I only ask because isError() is a method of the PEAR class, so maybe I'm not including the main pear class, and if I was all this would be sorted!!!!!

Well the cold hard truth is the book is probably written that badly. My guess is it probaby won't hurt anything to surpress the notice errors just to see the book's code in action.
Have you used Pear before? I'm not on the up and up on Pear. I did some fooling with the .mp3 parsing library. I know I had to go through all this extra installation business to install it on Windows. And then I downloaded the library I wanted to use and included it and used it like any other class.
This line is proper syntax, but you aren't using it from within the context of a class, so PHP is choking on it.
var $_oMail;
Of course you can test your script outside the context of the book's code.. you just need to understand all the required arguments.
I'm thinking "=&" is a shortcut of some kind for instantiating a class, I could be wrong about that.
This looks like its expected to be written and created within a class. You're creating a static variable and then instantiating an instance of the pear mailer class and storing it in that static variable. But this code isn't structed in a class. '$this->' is used inside of a class to refer to an object or method of that class. Its allows the class to talk to itself.
Code:
<?php
require_once("Mail.php");
require_once("DB.php");
var $_oMail;
$this->_oMail =& Mail::factory("mail");
if (Mail::isError($this->_oMail)) { // this is line 58!
echo($this->_oMail->getMessage());
}
?>
Lemme have a look at the source code for this so I can get an understanding of what's going on and I'll get back to you.
If you're using the book's source code as it was without modification and are getting all of these errors, then maybe something is wrong with how pear is set-up. Again lemme do a little research about it and I'll get back with you.
