Hi Eddie,
there is a great calendar package in PEAR:
http://pear.php.net/package/Calendar
There is a good example of how to build an HTML calendar from it:
http://pear.php.net/manual/en/package.datetime.calendar.intro-inahurry.php
(scroll down to the middle of the page)
I don't know why you want to use javascript here. I would do it this way:
- select all dates of free vacation properties of the given/current month
- put the dates from the DB result into an array
- create the calendar with the example from above and check for every day if
there is an entry for the day in your array
- if so give the table cell a specific color and/or link to page containing
detailed information
- otherwise blank the cell out or whatever
Hope this helps!
Regards, Torsten

Hi,
I'm almost ashamed to ask this question as surely enough the
problem is something very basic but, nonetheless, I can't put my finger on
it. I'm trying to implement the concept of a library (library.php) on PHP
where I define (once) all auxiliary functions and then use them in a file
(for instance index.php) via the 'require' or 'include' constructs. Here's a
reduced version of what I'm doing:
index.php:
<?php
$lang = (isset($_REQUEST['lang']) ? $_REQUEST['lang'] : "es");
echo "index.php: include_path is " . (ini_get('include_path'))."<br>";
require("http://tristan/library.php?lang=$lang";);
my_function("en");
?>
library.php:
<?php
echo "library.php: Called with $_SERVER[HTTP_HOST]:/$_SERVER[REQUEST_URI]
<br>";
function my_function($lang = "es") {
echo "my_function() says $lang";
}
echo "library.php: loaded<br>";
?>
When I load index.php I get the following:
index.php: include_path is .:/usr/local/php/4.3.6/lib/php
library.php: Called with tristan://library.php?lang=es
library.php: loaded
Fatal error: Call to undefined function: my_function() in
/www/htdocs/index.php on line 5
It seems that the name space on index.php never gets updated
with the function definitions made on library.php. What am I doing wrong?
Thanks! Cheers,
Daniel

Hi Daniel,
take a look at this section of the manual about including remote files:
>>>
If "URL fopen wrappers" are enabled in PHP (which they are in the default
configuration), you can specify the file to be included using a URL (via
HTTP or other supported wrapper - see Appendix J for a list of protocols)
instead of a local pathname. If the target server interprets the target file
as PHP code, variables may be passed to the included file using a URL
request string as used with HTTP GET. This is not strictly speaking the same
thing as including the file and having it inherit the parent file's variable
scope; the script is actually being run on the remote server and the result
is then being included into the local script.
<<<
Try including it as a local file:
require_once library.php'; // if it is in the same directory as the file you
have this line in
Also you don't have to pass $lang via Get to the file as the included code
will have access to $lang as it is then in the scope of the script.

Forgot a quote here, sorry:
require_once 'library.php';

Think you want something like this.
require("/tristan/library.php");

Not to mention misleading, since it doesn't always populate
$HTTP_RAW_POST_DATA when enabled. Always should mean always.

No, no, that's crazy talk. :-)

Hi all,
Some of my webpages are no longer working with the IE browser after MS
implemented some security patches which disable sending authentication info
through the URL:
http://user:[EMAIL PROTECTED]
This no longer works with IE, but is fine with most other browsers. Does
anybody know of a workaround using PHP to send the user & pass "in the
background", i.e. without user interaction?
Thanks for your help!

Merlin,
All I can suggest is that you attempt to restructure the include files
on the next version of the app, so that the functions and includes are
broken in the most logical manner possible (by task or topic for
example), so that you're only including the bare minimum of files for
each request/screen of the app, rather than including a whole bunch of
stuff that may not be needed on every request.
As an example, you might have an include file dedicated to file
uploads, which might be 10 or 20k. It's pointless to include such a
file on every request, since it's only required by a small
module/section of the site. Same goes for your login functions (which
are only required on login and logout), your form validation libraries
(only required when there's a form to validate), etc etc.
You may also decide it's not worth the work... to bench mark, make a
copy of all the code necessary to have a certain part of the site
function, but without grabbing anything unnecessary. Run the site with
the big includes (250k) and run the stripped down version a few times
each (using microtime() for timing it), and compare the results.
If even that sounds like too much work, you may be able to fabricate a
test case using dummy functions and code, which may give some accurate
answers, or may not :)

Hi there,
I am working on a complex webapp written in php. Recently I was
reading about performance issues and after analysing the code I found
that most of the files load 5 external php include files to run. All
together those include files make about 250KB (there are 5 files).
Now I am wondering if loading 250KB on include files, each time a page
= php script is called, is slowing down the webapplication a lot or
not. Is this even
noticable while surfing the site. I am wondering about response times
since I found them a bit slow (the time I click on the link until the
page starts to display).
Thank you for any advice,
Merlin

Hello,
How does one get sessions working on Windows? I have modified my php.ini
file so that session.save_path = C:\Temp, restarted and Apache. Still I get
this error message:
Warning: session_start(): open(/tmp\sess_26310affee160329c9e50f27663f8971,
O_RDWR) failed: No such file or directory (2) in
c:\apache\htdocs\dbmdata\admin\61646d696e.php on line 2
This is the code that is triggering the error. It seems very straightforward
to me:
session_start();
echo $_SESSION['user'];
Why is this so incredibly difficult?
Thanks,
Dave

Sounds right.
Do you have a C:\temp directory?

check you have edited the correct php.ini -- run <? phpinfo() ?> and check
where the ini file is to make sure you changed the correct one...

Hello,
Does anyone know of an open source "user/group" based
permission system built with php/MySQL?
That is, the effective rights for any user on a
specific secured object are computed from various
permit/deny permissions assigned to the user or any of
the groups he/she belongs to.
PEAR::Auth seems only to support basic user
authentication.
Thanks,
David

Drupal [ http://www.drupal.org ] has this functionality built in, but I
don't know of a standalone script that does this.

If you're running windows, most likely all you will have to do is change
your php.ini.
The OS used is Windows XP.
Open your php.ini file, set your extension_dir variable to where the
extensions directory is. If you installed php in c:\php, then the
directory is c:\php\extensions.
The gd library is bundled with the .zip package for Windows. If you
downloaded the .exe (binary installer), you may be missing some
extensions. Download the .zip file for Windows, uncompress it, and then
copy all the files from the extensions directory into your local php
install folder.
Once you've done that, uncomment remove the ; from the line in php.ini
that reads ;extension=gd.dll ( I think that's what its called, may also
be gd2.dll ). Save php.ini, restart your web server, and then view the
output from phpinfo();
Should see the gd extension enabled :)
