IE8 is the most CSS2 standards compliant browser, if I recall they
submitted 5 or 6 dozen tests to the w3c that they were the only
browser that passed. As far as selectors go:
http://msdn.microsoft.com/en-us/library/cc351024%28VS.85%29.aspx#selectors
looks to me like they're fully compliant with CSS2.1.

this is a very good startup for the issue. now the question is where does it
get the value if there is no max(ai) or when I do an insert in an empty
table with the ai field set to 1 where does the innoDB get the next ai value
10720 ?
I assume that the SELECT MAX(ai_col) FROM t FOR UPDATE; return is
incremented by 1 so how does this end up with 10720?
anyway, ur statement shows that there has changed somethimg definately. but
what?
maid be there is some flag telling the kernel that ai fields should be
unique throughout the database? some left behind of the cluster version of
mySQL?

I should mention that I use MyISAM as storage engine what makes it even more
wiered.

Sounds like a problem waiting to happen.

You mean the non-greedy flag? I think that's necessary the way the
regex was originally formulated -- without it, ".+display" would
gobble up all of the list-items until the last one.

Hi sunday coders,
I've been using this kind of logic on one PHP site I work on to
display one thing or another depending on whether the form was
submitted or not:
if($_POST['UserWishesDateRange']) { //--line 79
echo'submitted';
} else {
echo'NOT submitted';
}
and it works great on that site.
But on another site it still works, but gives this error:
Notice: Undefined index: UserWishesDateRange in /home/vs/site/phvs/bl/
7solarsecrets/admin/trackingcode.html on line 79
I assume that is because the error display settings are set to a more
rigorous level in this latter site.
Is this correct?
(Both sites reside on servers where I am not the admin.)

You could do something like:
if(isset($_POST['UserWishesDateRange'])) { //--line 79 or you could
use something like !empty($_POST['UserWishesDateRange'])
echo 'submitted';
} else {
echo 'NOT submitted';
}
This will check if $_POST['UserWishesDateRange'] is set to
something. You are getting the error message because $_POST
['UserWishesDateRange'] is not set if the form is not submitted. The
server where you don't get the error message probably just has error
reporting turned off.

Try this instead:
if (isset('UserWishesDateRange'])) {
// [...stuff goes here...]
}

It's either the 'error_reporting' configuration directive that's
different between the two servers, or 'display_errors', or both.
On one server the E_NOTICE bit-field is set in 'error_reporting', and
it sounds like 'display_errors' is also set (unless you're seeing that
notice in a log file).
On the other server, one or the other of those things is not set (or
both of them aren't).
You can use call ini_get('error_reporting') and
ini_get('display_errors'), to see what they're set to on each server.
Or just create a small page that only calls phpinfo(), to see all
configuration directives.
Here's the write-up of the directives (one is right below the other):
http://us3.php.net/manual/en/errorfunc.configuration.php#ini.error-reporting
As others have pointed out, it's a good idea to call isset() on a
POST-variable before trying to get at its value. This will avoid a
notice being thrown.
Lately I've stopped touching $_POST directly and started using
filter_input() instead; this also avoids the problem and provides
several other benefits:
http://us2.php.net/manual/en/function.filter-input.php
The filter_* functions are only available in core since 5.2.0, though.

Thank you guys for the isset() heads up. And Ben, for this good
explanation of error reporting!
As others have pointed out, it's a good idea to call isset() on a
POST-variable before trying to get at its value. This will avoid a
notice being thrown.
OK, and I can work around all this anyway, but I would love to get it
all in one line of code, that essentially says: (pseudocode)
if ($IamNotEmpty && $IamEqualto='T') {
(where those are both the same var)
http://us2.php.net/manual/en/function.filter-input.php
The filter_* functions are only available in core since 5.2.0, though.
OK, ..good to plant seeds, but since that server is PHP 4.3, I'll save
my brain now for until I can actually integrate that study.

Thought I tried that. Apparently not exactly; it works now! Thanks.
I know it is clunky but I wanted to see how compact it could be done.

They are the different way of the programming php.
PHP is the Temple Of the Shaolin, those fw programmers are master of the
techniques.
They are generate their way of the PHP-FU. Like kung-fu there are many ways to
do things in php.
From my point of view. All of them sh*t load of bloated code masterpieces.
After RoR craze, Nearly every PHP developer sees the light in a one night.
Then PHP Frameworks was skyrocketed. And Zend jump the bandwagon.
Main point of Framework craze was not technical. PHP was loose type language,
you can easily mess up your self in seconds and in the Internet you can see
giantic size of spagetti code. Because of this, Java and .net programmers
constantly mauls PHP as non enterprise language.
So ? What is the point ? The point is, As a company owner or the project
manager when you get a Certified this or that framework master, you can easily
adopt a standard to your projects, plus, you can get support and more
important than that you can show your badges and whistles to your customer to
prove yourself as a Experienced php crafter.
In simple, They says to your customer, you are in safe, these guys knows php,
you can buy things from them even if they blows things up, you can find another
certified master somewhere else.
From my point of view.
If you want to learn a Framework, I suggest you to learn a CMS/Framework,
something like TYPO3.
Because, after installing learning maybe certifying a framework, you have to
do tons of coding to generate a usable platform. For example you have to write
a session controller, have to generate a administrator interface, this that
yada yada.
So why you have to do all of this. Use a CMS/Framework and do just you need.
Plus, TYPO3 also has same badges and whistles (if you wish) for your
customers. Even in Germany it has bigger balls too.

There is, the entries are grouped by its index. So, I group name[0],
email[0], and sex[0] as one. The problem if I don't maintain the index for
radio buttons, the index could go wrong.
In the previous example I gave, if entry2 is deleted (and I don't maintain
the index) then entry3 will contain name[1], email[1], and sex[2] which
isn't desirable.
