I have a question about your suggestion.
Would it not be easier to simply carry the sessionid from the php session
validation to the javascript?
Instead of: if(document.frmlogin.txtusername.value=="")
{
alert("Please Enter Username.");
document.frmlogin.txtusername.focus();
return false;
Why would I want to "re-enter the user name"?
My common sense "which maybe completely wrong" say, YOU ARE VALIDATED IN
PHPBB via issetid, now post to (document.frmlogin.userid.value=="")
This is why I am not catching your angle.
PhP makes so much more sense. This javascript integration is really giving
me a headache!
Suggestions?
Brad

Eh? I never sent you to a website.
See this code:
function validatelogin()
{
if(document.frmlogin.txtusername.value=="")
{
alert("Please Enter Username.");
document.frmlogin.txtusername.focus();
return false;
}
if(document.frmlogin.txtpwd.value=="")
{
alert("Please Enter Password.");
document.frmlogin.txtpwd.focus();
return false;
}
document.frmlogin.login.value="Success";
document.frmlogin.action="operation.php?mode=login";
return true;
}
You need to create a *similar* function (eg 'BBValidateLogin()') to
check different html field names.
For example:
function BBValidateLogin()
{
var f = document.forms[0];
alert('username is ' + f.username.value);
}
The username.value comes from this:
<input type="text" class="post"
name="username" size="25" maxlength="40" value="" />
where you have name="username"
So take the name="..." and put a .value on the end.
Rinse, repeat until you have checked all of the fields you need to.
Return true for the form to submit.
Return false for it to NOT submit.

Hey!
.....A little background:
We have a site that has already been made.. a couple of hundred pages displayed
via SMARTY templates, the site's in Swedish.
The navigation and other parts except for the center is taken care of by the
templates and other scripts... the center main text is taken from the
database(mySql) based on $page_id...its in a MySql TEXT field and has all the
html etc that will be displayed in the center of the page.
....End of background..
Now they want to add a "search function" to the site... a simpe textbox where a user
enters a word or sentance and they get 20 results per page... with a "x.xx % closest to your
query" can anybody give me basic pointers on where to start?
Any links/software or articles too would be appreciated...
http://dev.mysql.com/doc/refman/4.1/en/fulltext-search.html
Start off with that, if they need something more complicated down the
line, revisit.

Hi..
In looking for what's required fo a site, I'm trying to find
docs/overview/mentors to talk to/etc,...
Basically, I'm considering what's required in terms of
hardware/apps/functionality for each server to be able to support a
site/system of ~100,000/day
Depends on your app and what you want to do.
If it's 95% "pull content from the database and display it" (eg a page
from an article), look at creating static html files which get
regenerated when the content is edited
(http://pear.php.net/packages.php?catpid=3&catname=Caching)
A webserver should handle 100k hits a day of static html pretty easily.
If you're doing complicated database queries with every page hit then
you're going to need a lot more database servers than http servers.

Hi Fellows,
I am developing on a large project. Its containing
a couple of ajax scripts. One day, my temporeary
folder was full, because everytime i clicked some-
where in the page, a new session file was created.
So i decided, to change to a database driven session
management. But it did not really help.
Its possible to log into the site. You can do authoring
or use the service as it should be, but after a little
time, the session is just lost.
Sometimes it takes ten minutes, sometimes just a few
mouse clicks. Its very strange.
But it never happens during the first clicks.
Maybe somebody is able to help me.
Best Regards,
Sascha Braun

Hello,
To me this seems to be a very strange problem.
I have a static html page (index.html) that shows correctly on both

I splitted the website up into different sections: (header,

do this I have used:

Some code goes here...
<?php

When I test my page (now index.php), it shows perfect on Firefox,

some stuff are not in their right place. I have checked the source

both index.html and index.php and they seem both identical to me.
Do you know why IE fails to correctly render the page?
Thanks

Could be stray carriage returns in your include files, good idea to
remove any '?>" in the include files as they are not needed.

Farid,
Can you copy each .php file to a .phps extension and link us to it?
That will allow us to view the source of each page and see for ourselves.
If there's any private information (passwords, database info, etc.),
however, please DO NOT do this. Only if it's a simple HTML-style page.

Thanks Daniel, Greg, Richard,
I made a script with:
<?php
print_r($_ENV);
?>
and it results only into: "Array ( )" nothing else ...
So it must be caused by a "different" environment ?
All I want is to check the $_ENV['OS'] within PHP scripts.

Subject: Re: [PHP] getting $_ENV variables
When I print_r($_ENV); from the CLI on 5.0.4 I get a bunch of results, no
problem.... but no $_ENV['OS'] variable. Further, when I check my phpinfo();
output, there are even fewer $_ENV variables printed than the CLI offers.
I'm not certain about this, Cor, but my guess is that PHP 5.x.x may have
altered the default $_ENV output to hide some of this information --- which is
a good thing, in my opinion, because then you won't just have some
run-of-the-mill script kiddie checking out the details of a box for known
security holes.
Of course, that doesn't necessarily stop <? passthru('uname -a')."\n"; ?>
or checking the $_SERVER['SERVER_SIGNATURE'] variable for the OS
information.... so perhaps this response is just one of those white-bread
responses. Something to chew on, but you really don't get anything from it.

Hi All,
I get nothing when using: echo $_ENV['OS'];
Also nothing when using: print_r($_ENV);
However, phpinfo(); show a full list of ENV settings.
How to get $_ENV variables ?
I am using PHP version 5.2.0.
TIA, Cor

By sending it out and checking to see whether it comes back on the next page.
Assuming your setup is:
session.use_cookies = On
session.use_only_cookies = Off
session.use_trans_sid = On
Then the sequence is this:
1. The first page involving a session will *both* send the cookie *and* append
the SID to URLs in the page.
2. So the next page request will return the SID, and if cookies are enabled
also the cookie.
3. On starting the session for this page, PHP will first look for the cookie:
if it's present, its value will be used and SID defined as empty; if not, the
browser must not be accepting cookies, so the value from the URL query string
is used and SID is defined with the matching string.
4. PHP now knows whether cookies are in use *for this request*, and *either*
sends the cookie *or* appends the SID to URLs in the page.
5. Requests from this page will thus *either* return the cookie *or* include
the SID as a URL get parameter.
6. Go back to 3.
Note that with this setup, you will *always* get at least one request with the
SID in the URL. Any site that doesn't do this has use_only_cookies turned on
or/and use_trans_sid turned off.

No, see above: they simply wait for the next regular page request to come in
and see if the cookie came with it. Nothing surreptitious or super-clever.
Cheers!

JavaScript (and AJAX) took the fun out of programming.
Before AJAX, programming for web was easy and fast. Now its the oposite.

Hi!
What do you guys use to develop ajax applications and do you have any
good articles on the subject?
I've just about finished an ajaxish site but it wasn't fun. A lot of
nesting javascript inside php calls, having to write the logic both in
javascript and php and so on. The source looks ugly and was time
consuming to debug.
Thanks!
Anything involving javascript development has several built in debugging
facilities
1: Alert dialogs: You may find it a chore to learn how to use them
effectively. But
the current content of any variable can be displayed with an alert
dialog. You
have to pay attention to how strings are concatenated; with +, The
actual
variable name cannot be quoted.
2: Browser error reporting, in Netscape species, javascript console. Take
a hint,
all source code text should be formated for Unix/Linux ( line feed
line endings)
If you do scripting on a Classic Mac OS <= OS9, the line endings are
carriage;
and Windows uses both carriage return and line feed.
return. You will drive your self crazy cussing the console because it
will not refer
to lines containing syntax errors, but some disrelated lines.
3. View source window in browser to see exactly what the browser is
getting on
page load.
4. Forms: I have coded special forms just for the sake of development and
debug
of javascript apps. All globals are visible through out the script,
WITH THE EXCEPTION
OF SOME THAT ARE DEFINED IN SOURCED JS FILES; Opening a javascript
window is
in a function does not seem to register if the function is in a sourced
file.
5. Patience, patience, patience, some masochism, Several large available
paper back
text books. No one will describe all you might need to know about
issues like rollovers,
DHTML, etc, Imagination and ingenuity, or the will to search and sift
through others
source code until you find what you are looking for, and then making it
work for you.
That's it, I have some suggestion that there are systems available for
javascript but I
have done without long enough to have my methods and approaches.
One more thing, php and javascript work very well together. I have even
written a
function to display php variable values as javascript alert dialogs. It
will not function
as break points for php like it does with javascript, but at least you do
not have to
decipher php error smeared all over the screen.
And Ajax, even though I have not cracked that particular aspect of
javascript as yet,
looks very worthwhile.
