it seems to silently fail.

Dang! You are exactly right - that isn't what I wanted to hear! : (
But better to know now, then when my timeline is already used up.
Did you write your own flash based solution, or use an canned one?

Nope, I choose not to complicate my life. :-)
Instead, I give the user one of these:

Besides, what does the user have to know anyway that makes it so
important that they see a progress bar?

I actually wound up using swfupload because of a friend's
recommendation and also because there's a nifty jQuery plugin for it.
The project's main site: http://swfupload.org
The jQuery plugin I'm using:
http://blogs.bigfish.tv/adam/2009/06/14/swfupload-jquery-plugin/
The *only* issue I could find with a flash based uploader (I don't
regard flash installation as an issue because we're a video based site
and well, if you're using our site to watch videos...) was there's an
as-of-yet unresolved bug in linux flash clients that locks a browser
until upload is completed. Adobe's bug tracker seems to be down for
me at the moment, but if you really want the bug, let me know offlist
and I'll supply it later. :)

Thanks Eddie. I will look into it.
I agree, if you don't have Flash use your telegraph or something.
Sheesh! (iPhone users excepted - they morn their lack of Flash)

Hey Eddie:
One more question...
I have an existing form that provides other data that need to be
linked to the file upload. It looks like swfupload, just uploads all
by its lonesome. I also need the javascript form validator to be
triggered before any uploading occurs. Is this possible? You don't
have to tell me how (though I wouldn't mind a few clues). I just want
to know if it will meet my needs once i dig in.
Thanks

That should all be possible. I'd take a look at
http://demo.swfupload.org/v220/featuresdemo/index.php as that has most
of that happening on the page and you can bootleg some of their
example code :)

Bummer... It looked so promising, but on Macs, Flash has to load the
entire file into memory to upload! Rrrrrrrrr. So, it isn't viable for
big files (Gig +) if you need it to be cross platform.
So now I am looking at perl of all things! If you have any ideas let
me know. thanks for all your help so far.

SERVER_NAME returns whatever apache has as the vhost's configured server
name.
the php manual says of HTTP_HOST: "Contents of the Host: header from the
current request, if there is one." in which the last 4 words are a little
off-putting. but:
http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.23
i much more encouraging. the field is mandatory and should have what i'm
looking for. it's absence is cause for a 400. casual testing (with a modern
non-ie browser) seems to bear this out.
so i'll try using that with fallback to my current techniques if i don't
find a good value in HTTP_HOST.

Hi,
Has anyone used Apache Httpd's mod_dbd connection pool in any of your PHP
app/project? Do you notice a performance increase from the overhead of
establishing/closing a connection?

the dbms abstraction library i use delivers rows, by default, as objects. so
i commonly handle dynamically generated data in the form of objects, though
it's not my code generating those objects. i think that's one reasons why i
often find i would use objects as data structures. and because i find the
dynamic objects in js convenient.
but i think you're preference reflects more closely was probably the concept
of php's version of oop: an object is an instances of a static class.
in any case, now that i've confirmed that i'm not merely unaware of the
features i was hunting for, and that they don't exist by design, i can
perhaps move on.
on a related note, way back when xml was ascendant as "the most exciting new
technology to hit the net since java", i was not impressed. what a horrid
syntax for specifying and communicating data, i would argue. why not use the
syntax from some sensible programming language instead? js, for example?
easy to parse, less overhead, human readable (i find xml hard to read), etc.
then eventually json happened, without all the hype and fanfare, just doing
the job very conveniently. i love it.
and to make that comment vaguely php related, i now use json to encode
structured data that i want to write to the php error log.

You're right, that isn't PHP syntax. One workaround that came to mind

a similar thing (although using a different mechanism) is this:
${$a ? 'a' : 'b'}->q
i would not have thought of that. interesting...
and while i'm at it, and using my original error, how come...
function o() { return (object) array('q'=>7); }
echo o()->q; // is ok syntax, but
function a() { return array('q'=>5); }
echo a()['q']; // isn't?
I'm afraid I can't answer that right now--it does perhaps seem
inconsistent at first glance,
although I can't say I've ever missed it or felt that using syntax like
that would make my
life any better. Maybe it would. Then again, I can also see an argument
being made for
allowing the object syntax but not the array syntax: in the case of
objects, you can have
a clean class declaration which is pretty much self-documenting, and
later users of the
class can have a clear idea of which properties are available and which
are not, and they
can thus be sure that o()->q will not result in uninitialized property
problems. Using the
array syntax you could never be sure that the index requested actually
exists.
Of course, this holds true only for people like me who don't really like
the idea of creating
objects on the fly in PHP unless there's a very good reason to. Usually
in PHP such tasks
are better handled by arrays anyway.
the dbms abstraction library i use delivers rows, by default, as objects. so
i commonly handle dynamically generated data in the form of objects, though
it's not my code generating those objects. i think that's one reasons why i
often find i would use objects as data structures. and because i find the
dynamic objects in js convenient.
Yeah. . .never been a fan of the libs which return objects, although
such a model does
perhaps have its uses.
but i think you're preference reflects more closely was probably the concept
of php's version of oop: an object is an instances of a static class.
Yes, I'd say the same thing, except I'd replace the term 'static' with
'declared'. If an
object is created on the fly, in someone else's code, and I have to
maintain that code,
then either that code must be well-documented or I have to go on a hunt
through
the source code to find out what might be available within that object.
Not my idea
of fun. Convenient for the original coder, perhaps, especially if they
come from an
automatic model background such as Javascript. And maybe one day I'll
come to
love it. So far I haven't seen enough of a benefit to convince me that
it's worth the
long-term maintenance headache it can (note that I say "can", not
"does") cause.
in any case, now that i've confirmed that i'm not merely unaware of the
features i was hunting for, and that they don't exist by design, i can
perhaps move on.
on a related note, way back when xml was ascendant as "the most exciting new
technology to hit the net since java", i was not impressed. what a horrid
syntax for specifying and communicating data, i would argue. why not use the
syntax from some sensible programming language instead? js, for example?
easy to parse, less overhead, human readable (i find xml hard to read), etc.
then eventually json happened, without all the hype and fanfare, just doing
the job very conveniently. i love it.
I also never found myself sold on the "XML everywhere" philosophy which
seemed to
spring up during its first few years. I have found it useful for certain
things--usually
involving documents. :) It's awesome for technical documentation such as
working on
the PHP manual; I've used it when writing books; and XML and the DOM can
be a
great help when constructing automatically validated XHTML. But there
are also many
other things which people insisted it would be perfect for which just
end up being a
waste of cycles and memory. It's a good tool for some tasks but
completely ill-suited
for others IMHO.
I like the idea of json when working with Javascript. Years ago (before
var_export())
I wrote something very similar to var_export() which would write out a
human-readable
and directly PHP-parseable string for structured data. Sort of like. .
.er. . .pson (*cough*). ;)
and to make that comment vaguely php related, i now use json to encode
structured data that i want to write to the php error log.
Interesting. For something like that I would just use var_export() and
skip the overhead
of parsing json back into PHP if I needed to do that. I'd use json when
using Javascript, though.
But whatever makes you happy--I'm certainly not here to try to change
anybody's mind
about that sort of thing.
Cheers, and good luck with the explorations!

Torben

Hello there,
I've been asked to create something like the tables you usually see, where the
headers are actually links and when you click the links, the table gets sorted
based on the header. Are there any classes that you know of that would do the
job? My current idea is to return an array of the colomn which contains the
data you want to sort on (like 'name') then sort the array and do something
like:
[code]
for (i = 0; i < length(array); i++)
mysql_query("select * from table where 'name' = ${aray[i]}");
[/code]
Any better algorithms anyone?
Thanks!

Your code looks like you're filtering and not sorting. You should revisit the
basics of SQL syntax.

My suggestion would be to have the client do it.

I use it on a number of different pages.

This could be done clientside if you intend to show all data. If you
want to implement paging too, you have to do it on the server though.

What you are trying to do is ridiculously easy, and something which I
accomplished years ago. Basically every column heading needs to be output as
a hyperlink which repeats the current page with the addition of
"orderby=<column_name>" in the URL. This information appears in the $_GET
array, so you just repeat the previous sql query with the addition of an
ORDER BY clause.
This assumes that you have already taken care of caching the query and
paginating the results.
You cannot do this in a separate class as it requires action in both the
presentation (UI) and data access layers, and a single class is not allowed
to operate in more than one layer.

I think the point of Andrea's project is to make debugging easier. Just like
firebug and Charles do in their own respect. Is it something you can do
without? Yes, especially if you have a great development environment set
up. Is is something that could make inspecting what is getting thrown around
in your AJAX calls and the PHP errors that occur easier? Yes, especially
when sending JSON or remote object calls.
Charles is a great tool when doing Flash and Flex remoting, and AJAX. I have
the impression that Andrea's tool is perhaps doing something similar, but
taking it a step further. Maybe not everyone's cup of tea, but I think it is
difficult to write off as useless.

From: Rico Secada [mailto:[email protected]]
Some time ago I developed a small web application that a bunch of users has
installed.
I have always used the DOCUMENT_ROOT for my includes, but the other day I
installed the application in a subdirectory, and as you've guessed a lot of
the includes didn't work.
I have been reading up on the subject of absolute vs. relative paths etc.
And on the subject of defining your own document root.
I need the application to be as user friendly as possible, and I would like
to avoid having users enter path details in the configuration.
What is the best way to solve this problem?
Rico.
--
Who are your users? Can users download the script and run it on their own
servers? If so there shouldn't be a problem asking them to set a path in a
config file because presumably the users would know something about servers
and paths, and presumably they'll know enough to create the directory and
copy the files there in the first place.
If you have an install process you can pick up the current directory from
system globals and write it to the path setting in the config file. You
might need two different absolute paths, one for includes and one for urls.
Cheers
Arno
