After much wringing of hands and gnashing of teeth, I found the problem.
Typo. Of course. I'd only read over the code about a hundred times before
I asked for help, if that's any consolation.

Ah, don't "oops" anything! That tip was worth its weight in gold to me!
In fact, it told me where one of the typos was that was causing a syntax
error during the initial parsing. The other typo was more insidious (trying
to use count() as $count()), but just as deadly to the output.
Thanks for the great tips!

drop the disappointment. your new to the game and most of the people on this
list that regularly answer the kind of questions you (will) pose are very
experienced and knowledgable. you may not always like what they say or how, but
trust that your going to get a lot of good quality advice from some smart
people.
... and your getting it for free, some of these guys charge hundreds of dollars
commercially for the kind of help they hand out here for free, mostly their here
wanting to teach newcomers how become decent coders which sometimes means
telling
them stuff they dont really want to hear.
so dont be put off so easily .. one day you might one of those old gaurds that
occasionally loses it after reading the umpteenth stupid question or ungrateful
reply :-)
have fun :-)

good advice.

less good advice. I agree you should be doing everything to make your code
validate 100% BUT having 100% valid code doesn't garantee jack about it
working on all browsers.
that said not having 100% validated HTML means you have nothing to
base anything on ... so the only sane option is to validate and then
work out any problems you have from that point.
And Al does implie an important point, namely that most errors will indeed
never surface when your HTML validates.

how large? for very big files it's dangerous to read them in all at once,
as was exampled in other replies. I would say that large in this case would
be anything bigger than 5 Mb (this is a very rough estimate, we could have
a whole thread devoted to this [issue])

I came across this page today:

It covers a lot of flammable material (echo vs. print) but I wonder
how valid some of the advice is. Can anyone elaborate? Thanks.

Some of it is definitely useful individually. Others are questionably
useful individually (echo vs print). But if like me, you adhere to most
of the optimizations as second nature, the cumulative effect is probably
perceptible. Going back and changing code to reflect some of the
optimizations though is probably not worth it.
Cheers,
Rob.

funny you should post this, I've recently been compiling a list and
trying to assign "weights" to them, based on different sites around
the web. ideally I'd like to get into showing the number of opcodes
for each operation and comparing it based on that (like Sara Golemon
did in her post)
http://michaelshadle.com/php-optimization/
I haven't formatted it all nicely yet, since I have to manually do it
inside of the WP editor. I thought about pulling it into a separate
page, or even making an interactive page where people can submit their
findings and code and vote based on their own knowledge or experience.

OK, I'm looking at the PHPEclipse site, and I've been here before: the current
Using PHPEclipse document lists the system requirements as PHP 5.1.2 or *below*,
and Apache 2.0 or *below*
Is that just badly out-of-date (last update is April 2007), or is PHPEclipse
really not able to support PHP 5.2.4 and Apache 2.2.4 (my current system
levels)?
Ask the phpeclipse guys, they write the requirements and will be able to
tell you what's going on with that.

Hi all:
This may or may not be a PHP-related question, but, since I'm coding with
PHP, I thought I'd ask:
When a form loads, such as a login form, I'd like to have the cursor placed
automatically in the Username field. Right now, it requires me to click it
with the mouse or to tab into it. I know I've seen this type of cursor control
accomplished on countless web pages, but I can't find any hints on how to
accomplish this on my own. Can one of you wonderful code wizards point me in
the right direction?
Also, while I'm asking questions, let me ask another one: I've seen several
pages (frequently, pages that come up after a login page has been filled out)
that provide some user mollification (you know, the typical "Please be patient,
don't get your nylons in a knot, we're typing as fast as we can" message),
often with some type of moving text or graphics (probably an animated GIF) that
then goes away after a certain time and a third page is displayed. I know that
the headers("Location") code can do this, but I was under the (probably
mistaken) impression that this will NOT work if information has already been
displayed on the page. If that's the case, how are these other pages doing
this? Knowing how to move from page to page this way would really be helpful.
Thanks so much.
Jon

you want javascript.
i'd recommend using jquery (jquery.com)
put an id="username" on the username box.
then do
<script type="text/javascript">
$(document).ready(function() {
$("#username").focus();
});
</script>
voila

Hmmm. It didn't work for me. Do I need to change any of the code you

Thanks, though, for the code snippet. I'll look up its pieces to see if

i don't believe so. it should trigger the focus event for that element ID.
of course you did download and include jquery.js in your page... can
you send me (off list) the URL to the page? i can help you out, but it
is off topic to PHP now :)

It's a javascript thing -- check out onFocus:

Here's a collection of animated wait gifs:

It only works if you have included the jquery javascript files.
If you don't want to use that you could do something like:
<script defer>
document.getElementById('username').focus();
</script>

yeah, but adding in jquery will open up his entire world :)
the example below will work without jquery. personally though i try to

Hi Mike, Chris, et al.:
Thanks for the info. I'm not certain if I'll be needing jquery, or what
benefits it might afford me with my meager little project, but I will check
it out.
In the meantime, Chris's snippet worked like a charm! Thanks!

Thanks. I'll check that out. I'm still wondering, though, how the
redirection works if it is supposed to occur only before any text appears in
the <BODY>.

It could, but it's an overkill for a simple input field focus thing, IMO.
It's like selling a guy a Hummer because he wants to drive on the
gravel on the side of the road.

in my experience it never stops at a single focus event on a login box...
but yes, i should have replied with the simpler solution first.

Steal as you need -- I did.
Thanks. I'll check that out. I'm still wondering, though, how the
redirection works if it is supposed to occur only before any text appears in
the <BODY>.
Don't confuse yourself -- it's simpler than your trying to make it.
You show the wait gif in the preceding (or current) page and it's not
a redirect.
It's simply:
1) The user enters a bunch of data and hits submit;
2) The form then sends that data to the server;
3) The form sticks around showing you a wait gif until the server
responds with a new page.
4) You don't need a wait gif for the new page.
OR
I use javascript to pre-process the data and do basically the same thing.
Here's a *required* entry form using javascript.
http://webbytedd.com/c/form-submit/
If the calculations in the background are significant with respect to
time, then I would throw up a wait gif instead of an alert.
However, I seldom write anything that takes that much time -- so it's
usually a moot point.
Here's another example:
http://webbytedd.com/c/form-calc/
I haven't seen too many forms that get more complex than that and the
computations there are instant -- so what's the point of a wait gif
in form processing?
Cheers,
tedd

1) window.onload = function () {formfield.focus();}
2) Meta refresh or some combination of Javascript, flush(), and
ob_flush().

Hi all:
This may or may not be a PHP-related question, but, since I'm
coding with PHP, I thought I'd ask:
When a form loads, such as a login form, I'd like to have the
cursor placed automatically in the Username field. Right now, it
requires me to click it with the mouse or to tab into it. I know
I've seen this type of cursor control accomplished on countless web
pages, but I can't find any hints on how to accomplish this on my
own. Can one of you wonderful code wizards point me in the right
direction?
Also, while I'm asking questions, let me ask another one: I've
seen several pages (frequently, pages that come up after a login
page has been filled out) that provide some user mollification (you
know, the typical "Please be patient, don't get your nylons in a
knot, we're typing as fast as we can" message), often with some type
of moving text or graphics (probably an animated GIF) that then goes
away after a certain time and a third page is displayed. I know
that the headers("Location") code can do this, but I was under the
(probably mistaken) impression that this will NOT work if
information has already been displayed on the page. If that's the
case, how are these other pages doing this? Knowing how to move
from page to page this way would really be helpful.
Thanks so much.
Jon

I added just into a input field"
19" enclosure
which was displayed from the database as:
19\" enclosure
That gives me some questions:
1. where the protecting slash comes from?
2. how can I get it away when I want to display that field?
3. The slash is not to see in phpmyadmin, why not?
and:
1. what else do I need to take care with input fields and if they are
going to a mysql database?
2. can I use a function for that kind of protection for each field - or
even better just flag it in php to protect?
3. is HTTP_REFERER & session-id enough to make sure that no variables
can be injected?
bye

1.Probably that's because the function mysql_real_escape_string() is turned on.
You can check that in your php.ini configuration.
2. If you want to display them as you wanted, you can use stripcslashes() on
your output contents.
3. Maybe phpmyadmin automatically stripped that out.
And
1. Any user input should be escaped before they went to database.
You can use htmlentities(), addslashes(), strip_tags(), etc...
2. You can encapsule those functions in a function, and use it for each user
input.
3. No sure. Probably they do.
Anybody any ideas?
Regards,
Shelley

Probably magic_quotes_gpc
2. how can I get it away when I want to display that field?
1) Turn off magic_quotes_gpc in a htaccess file:
php_flag magic_quotes_gpc 0
2) When you insert the data, use mysql_real_escape_string
3) When you display the data, use htmlspecialchars or htmlentities
3. The slash is not to see in phpmyadmin, why not?
It probably has code to pick up magic_quotes_gpc and work around it.
1. what else do I need to take care with input fields and if they are
going to a mysql database?
Use mysql_real_escape_string
2. can I use a function for that kind of protection for each field - or

There is no flag, you need to use escape_string for each field.
3. is HTTP_REFERER & session-id enough to make sure that no variables
can be injected?
No way. Never ever ever ever trust user data (did I mention never
ever?). Authenticated users can do just as much damage as an
unauthenticated user.
Read http://phpsec.org/projects/guide/ before you touch any more code.
