Re: [PHP] Shoutbox suggestion needed
The main issue with these systems is updating the client on a regular enough basis. If the content is time critical, like with Facebook chat, then you need to do long polling. However for a Shoutbox, because it's more like an IRC channel with people 'shouting' to a channel, you can probably just set the client to automatically update on a regular basis. Or even more advanced, would be to get it to check in increasing intervals. Firstly it checks 0.5s later, then 1s later, then 2s, 4s, 8s, 16s, with a limit of 60s (i.e it checks at least once a minute for an update), upon new content being received the time is reset back to the 0.5s If you need to do long polling http://ajaxpatterns.org/HTTP_Streaming then look into the Tornado Webserver http://www.tornadoweb.org/ which Friendfeed http://friendfeed.com/, and more recently, Facebook use (for their LiveFeed system).

It's often been argued back and forth whether people have Javascript turned off. I suspect the vast majority of people have Javascript turned on. However, Java is another story.

Java is available on all the main browsers, and generally only needs one to accept the applet. For a chat application to be written using only Ajax technology, well, like I said before, if Facebook tried it and still can't get it right with all the financial backing they have, what hope for someone to release this sort of thing open source and Facebook not be aware of it?

[PHP] Re: [php] [mysql] select and subselect
Allen McCabe wrote:
I have a page on my site where I can optionaly filter by certain fields
(order by filesize or file category), but I am implementing a shopping
cart type of idea where users can submit an order.
As administrators, my coworkers and I need to be able to filter orders by
their contents. For example:
View all orders for Jack and the Beanstalk, where an order may have Jack
and the Beanstalk and other items.
I have an order table that keeps track of the order_id, the date, the
status, etc. I also have an order_lineitem table that is the contents of
the order. This has a one-to-many structure (without foreign keys because
it is mysql).
I was baffled as to how to filter the orders by the item_id that appears
in the order_lineitem table.
I just came up with this, but I'm not sure how the mysql_queries will
handle an array. Do I have to do some extensive regular expression
management here to get this to work, or will it accept an array?
?php
if (isset($_POST['showid']))
$showid = $_POST['showid'];
$subSQL = SELECT order_id FROM afy_show_lineitem WHERE show_id =
{$_POST['showid']};;
$subResult = mysql_query($subSQL);
$where = WHERE;
$extQuery = 'order_id = {$subResult}';
}
$resultOrders = mysql_query(SELECT * FROM afy_order {$where}
{$extQuery};) or die(mysql_error(Could not query the database!));
?
If $_POST['showid'] is likely to be an array, use implode to create a comma
separated string of values, then use IN to build the query.
$ids = implode(',', $_POST['showid'];
$subSQL = SELECT order_id FROM afy_show_lineitem WHERE show_id IN ($ids)
But you need also to check your logic - your query above will have two WHERE
in it and will fail miserably :-) And your call to mysql_error will
probably not help you either, as the (optional) argument should be a link
identifier, not a string of your choosing.

$subResult is a resource. You need to fetch the results
before you can use them like this. Maybe something like:
/* UNTESTED */
/* Don't forget to escape! Some will argue that
you are better off using prepared statements. */
$showid = mysql_real_escape_string ($_POST['showid']);
$q = _
SELECT `order_id` FROM `afy_show_lineitem`
WHERE `show_id` = '$showid';
_;
$res = mysql_query ($q);
if ($res) {
while ($row = mysql_fetch_row ($res)) {
$ids[] = $row[0]; /* Assuming numerical ids. */
}
$ids_spec = implode (',', $ids);
mysql_free_result ($res);
} else {
/* Handle error */
}
if (isset ($ids_spec)) {
$q = _
SELECT * FROM `afy_order`
WHERE `order_id` IN ($ids_spec)
_;
$res = mysql_query ($q);
if ($res) {
/* Do stuff */
} else {
/* Handle error */
}
}
But you could also do it in one query (*untested*):
/* UNTESTED */
SELECT `ao`.* FROM `afy_order` AS `ao`,
`afy_show_lineitem` AS `asl`
WHERE `ao`.`show_id` = $show_id
AND `asl`.`order_id` = `ao`.`show_id`
Or maybe there are better ways, such as using INNER JOIN,
but those sometimes end up using a temporary table...

Re: [PHP] How to call DLL in Javascript
I don't think you can di this with client side js. It would have to
run outside the security sandbox and that is a bug no-no.
If the dll is in the server, you could potentially call the server via
Ajax to instantiate the dll and have it's output sent to the browser

usually .dll should be running client side not server side
jscript and javascript are two different beasts based on ecmascript;
you'll be wanting to get some JScript (microsofts own version) help for
this.. http://msdn.microsoft.com/en-us/library/7sw4ddf8%28VS.85%29.aspx
but as somebody else mentioned, you won't get it working on all browsers
AFAIK.. so running DLL on server side and calling wrapper functions via
ajax is more appropriate.
an asp.net forum or suchlike will probably yield a more useful response

Re: [PHP] PHP httpd debug question
Hi, I am not getting what are you asking but if you want to run two httpd then you have to run those on different ports. For this you can change Listen 80 to Listen 2020 from httpd.conf file. So that one server will run on 80 and other will run on 2020. you can change 2020 to whatever port you want .. but check if that port is not already assigned to some other application.

Thanks for the feedback. That's big help. I'm sending this revised code to my

Actually, I do check if EMAIL_MODE is defined; just didn't show it here.
And, I have debug mode that provides a more detailed error report. But, it
doesn't help if it can't even find Mail
if (PEAR::isError($result))
{
$mode = EMAIL_MODE;
throw new Exception(The email mode \$mode\ does not work. Check the
Applic email address and password in config file. br /
