Wow, I really hadn't thought of using RSS, what a good idea! What does 
MagpieRSS do with the feed exactly? Does it output an array?

I'll have a proper look when I get chance but I will probably be back to 
ask for some hints at least!

Also, can you think of any way of permenantly associating images with 
events in this way? Or at least a unique ID for each event so I can use 
that to refer to images with.

Many Thanks for this

Re: [PHPiCalendar-DEV] phpicalendar lite

[Blaine C. <la...@us...>]

There was a recently applied patch to the RSS feeds that allows you to 
get an arbitrary x days; if you're using PHP (as I assume you are), use 
MagpieRSS ( http://magpierss.sf.net ) to fetch the RSS feeds, and you 
have exactly what you're looking for, available at almost zero 
dependency cost within whatever code you're working on.

If that still doesn't make sense, let me know and I'll post some 
running code.

===Aim===

I'm also working on a kind of "phpicalendar lite" as mentioned 
previously on the list but I called it content management.

I want to be able to generate a web page showing the next few events 
coming up with a title, description, start date and time, end date and 
time if applicable and which calendar they've come from.

===Problems===

I'm struggling a little with manipulating the master_array returned by 
ical_parser.php. It would  make more sense in my head if I could get 
from the multidimensional format of the master_array which is something 
like...

[20050222] => Array
        (
            [1600] => Array
                (
                    [8D69CBD9-8664-11D9-8CFA-000D936C280E-RID] => Array
                        (
                            [event_start] => 1600
                            [event_end] => 1700
                            [display_end] =>
                            [start_unixtime] => 1109088000
                            [end_unixtime] => 1109091600
                            [event_text] => Recurring+Event
                            [event_length] => 3600
                            [event_overlap] => 0
                            [description] =>
                            [status] =>
                            [class] =>
                            [spans_day] =>
                            [location] =>
                            [organizer] => a:0:{}
                            [attendee] => a:0:{}
                            [calnumber] => 1
                            [calname] => exhibitions
                            [url] =>
                            [recur] => Array
                                (
                                    [FREQ] => daily
                                    [INTERVAL] => 1
                                    [UNTIL] => February 25
                                )

                        )

                )


to something more like a flat table....


[8D69CBD9-8664-11D9-8CFA-000D936C280E-RID] => Array
        (
            [event_text] => Recurring+Event
            [start_date] => 20050222
            [end_date] => 20050225
            [start_time] => 1600
            [end_time] => 1700
            [calname] => exhibitions
        )


This might be similar to what the draw_print function in 
functions/template.php does, but... well I don't understand it!

My main problems are:
1) A recurring event only needs to appear once
2) I need to get an end date for recurring events
3) My skills with PHP arrays are very limited.


===Other Questions===

1) What are the dependencies of the ical_parser.php file? Does it rely 
on any files other than init.incs.php, date_functions.php, 
draw_functions.php, overlapping_events.php and timezones.php? If not, 
can I use the functions directory on its own without the rest of 
phpicalendar in an entirely separate directory?

2) I'd really like to be able to associate images with events and I'm 
not sure how to achieve this. Perhaps I could create a directory of 
images with the directory name matching the UID of the events. Or 
perhaps I should generate a MySQL database from the .ics file with UIDs 
and fields for image paths. I could even create a table from the array 
I'm trying to create and store all the calendar data in the database to 
increase the speed of execution.


There's a good chance I'm approaching this in entirely the wrong way. If 
so, please put me out of my misery!

Thanks

[PHPiCalendar-DEV] Modifications added to CVS

[Jim Hu <ji...@ta...>]

OK, sorry if I did this clunkily, but after all these months I think I 
have cvs working on my Mac (it was working on my mac all along, but not 
in my brain).  I've uploaded the modifications to allow calendars to be 
placed in different subdirectories and to have these specified by the 
$_REQUEST variable cpath.  I also uploaded major changes to rss.php 
that base all of the feeds on asking for a range of dates.  Requesting 
week and month now calculates these ranges and treats them like any 
other range.  This also allows there to be only one block of code to 
actually generate the XML/RSS instead of three.  I've done some 
weirdness with that to fit my own needs - some of my changes there 
probably need to be undone in the long term goal of following RSS 
standards.

Chad, please let me know if this worked.  When I tried just now to look 
at the CVS repository via browser, it didn't work...I hope I didn't 
break something.

This is my first post. Please forgive me if not in order. Having a

Anyone care to simply share the code that can do this or post it  
somewhere where one could simply hack it to our needs? I have multiple  
sites I'm developing that could use this functionality (simply listing  
the next XX events or XX days from an .ics file) dropped onto a PHP  
page.

I'm not as much a PHP guru as I'd like to be, but having an example  
would allow me and others to make changes as necessary, and  
phpicalendar has just a few too many functions/files/variables to cover  
and eliminate for a simple list.

Thanks,
Brett

Re: [PHPiCalendar-DEV] phpicalendar lite

[Chad L. <ch...@ch...>]

It is fairly modular. If you know PHP arrays it is very simple. At the=20=

end of ical_parser are some comment tags, uncomment the $master_array=20
and you will see our structure. Each page (day, week, month, ect) is=20
simply a different manipulation of this array.

Re: [PHPiCalendar-DEV] phpicalendar lite

[Alex J. <al...@ph...>]

I think there's GREAT interest in this...Either it would show the
next...say, 5 events, or perhaps something that would show, in text form,
events for the next 2 or 3 days.

there was traffic on this list a long time ago looking for such things,
so, if even you don't officially fork the file, make your work available
for download, please!!

Yeah. I suggest you hack something up in 
functions/calendar_functions.php to return the correct list of 
calendars based on your particular setup. If you get something 
integrated well but in a generic fashion, perhaps you can submit it as 
a feature request.

If you want to make this work for your site in the meantime, play 
around with functions/calendar_functions.php.

Yeah. I think you should use a combination of the HTTP authentication 
and the referring URL to modify functions/calendar_functions.php so as 
to show only the calendars appropriate to the user's web space. I think 
that should give you exactly what you want without having to copy 
config.inc.php for every user.

You could also create a new users.php file in the single PHPiCalendar 
directory (remove the .php if desired by adding an entry to specify the 
default file type and handler in .htaccess), then use 
functions/calendar_functions.php with the query path to get into a 
specific user's directory.

e.g. http://www.domain.com/users.php/wesley/

This also removes the need to link files in user directories. Adding or 
removing a user would only require creating/deleting/locking out 
directories and updating your htpasswd file.

Hope this helps,

Hi,

You probably just want the parts of PHPiCalendar that parse the .ics 
file and create the Calendar object. Once you've got that, you can pull 
out individual items and display them however you want. Just use the 
files that are called by the display files (e.g. you want stuff like 
ical_parser.php in the functions directory) for your own version of 
day.php.

I think that's the gist of things. Chad might be able to give you some 
more direction.

Later,
Wes

I thought about using those options at the end of the config.inc.php 
file, but realized it would be an administrative nightmare if there are 
many users and many calendars. I suppose one could run a cron job to 
search for calendar files in a certain user's directory, but then the 
user would have to wait until it ran...and I'd like to make simple 
viewing of calendars in a user's public calendar directory not require 
any authentication.

Basically I want it to work as if I had phpicalendar installed in every 
users' public calendar directory so that visiting 
http://domain.com/calendars/public/user displays all calendars found in 
that directory at once.

Here's what I have done (seems to work OK), but it seems like it should 
be easier ;)

1. installed phpicalendar in a web directory

2. linked to all files/directories contained in phpicalendar from users' 
public calendar directory *except* config.inc.php

3. copied a generic config.inc.php and replaced the line about calendar 
path as appropriate (this is different for each user)

I did the same thing for private calendar directories, and as expected, 
the user gets prompted for credentials to even view the calendars.

I'm not sure if I'm making any sense here, and there's probably a better 
way of explaining what I was after. I've hacked some php but I'm not 
particularly qualified to see how easy it would be to make this set up 
possible out of the box...

Best,
Todd

[PHPiCalendar-DEV] phpicalendar lite

[<ze...@bo...>]

i was looking for a solution where a client could publish an iCal file
from their powerbook and have upcoming events parsed and listed on a
webpage.  i found this project which seems to sorta do this and alot more=
.
 it's really well done, but over-kill for my needs.

i hacked up the month view and associated template to get a
close-to-desired effect, but it still is very calendar quantized (month,
day, year centric).  i really just want to lists the next so many events
in a simple format.

i'm starting to get a small handle on the project code but it's still
imtimidating.  any suggestions on how to approach this and maybe fork a
really lite version... a simple iCal parser thingy?

Erm, Apple iCal, Mozilla Calendar? I presume I'm referring to the right 
part of the RFC. A URL attached to an event.

Oh OK. Just a note on this, whilst experimenting I've noticed that URLs 
in the description field don't work consistently between normal view and 
printer friendly view if written in HTML.
For example, if I type...

<a href="http://example.com/page.htm">more...</a>

into a description field, if you click on the event in a normal view you 
get a popup in which the HTML breaks. If you go to printer friendly 
view, the HTML is parsed correctly and works as intended.

If you don't use HTML and just type a URL in plain text, it becomes a 
link as you describe in normal view and is not clickable in printer 
friendly view which is fair enough.

A demo of this can be seen at:
http://www.catmosearts.co.uk/calendar/week.php?cal=all_calendars_combined971&getdate=20050209

I suppose this is just because you're not supposed to put HTML in event 
descriptions! But the inconsistency is a little frustrating.

Re: [PHPiCalendar-DEV] URLs in iCalendar events

[Chad L. <ch...@ch...>]

HI, we don't have support for the URL property tag of RFC2445. To my 
knowledge I haven't seen an application that uses is and it's never 
been requested by our audience.

You can put URLs directly into the Description field and we'll convert 
them into an href upon displace. I also believe we do this for the 
Location field as well.

If you want to submit a feature request, please do so on the 
Sourceforge site and attach a sample calendar.

Thanks,

[PHPiCalendar-DEV] URLs in iCalendar events

[Ben F. <li...@hi...>]

Hi all.

I can't seem to get phpicalendar to display the URLs associated with 
calendar objects. Each event in my calendar has a web page associated 
with it which gives further details (retrieved from a mysql database) 
about the event. I had toyed with the idea of actually putting this data 
within the iCal file itself, but I don't think it's flexible enough. I 
need to be able to separate it into lots of fields such as "price" "film 
rating" and things. So I'm trying to put a link in each calendar object 
to point to more information.

Is the URL feature of calendar events turned off in phpicalendar on 
purpose, perhaps because of security issues? Is it possible to turn it 
on? Are there issues associated with this?

Many Thanks

Ben

I believe it is the case that if you list all a user's public calendars 
in apache_map, they will be seen combined instead of individually. But 
only when that user is logged in via HTTP authentication. If you want 
everyone to see that user's public calendars combined...I don't think 
that is supported right now.

To block private calendars, they need to be added to the locked_cals 
list in config.inc.php. Unfortunately there currently is no way to 
specify a list of directories or a regular expression to identify 
locked calendars. Maybe a good thing to add to the feature requests on 
SourceForge.

Then map locked_cals calendars to users in apache_map to allow users to 
see their private calendars.

Not sure what you want to do here? Can you give an example of what you 
want your config.inc.php to look like?

[PHPiCalendar-DEV] Multiple users and security problem

[Todd S. <to...@we...>]

I couldn't find an answer in the README or the list archives, so here 
goes. I'm using webDAV to allow folks to publish calendars, but I've 
created a structure like this:

/var/www/calendars/public/user1 user2 etc.
/var/www/calendars/private/user1 user2 etc.

In an httpd conf file I have the directory options set so that anybody 
can read public calendars but only the user can publish; for private 
calendars, only the user can read and publish.

What I'd like to do is use phpicalendar so that each user could see 
his/her public calendars combined, but I haven't been able to find a way 
to do that. It seems I would have to have a separate config file for 
each to point to the users public calendar directory.

Just playing around I pointed to /var/www/calendars as the path to 
calendars. I then noticed that I could add 
"month.php?cal=public/user1/calendarname" to display a particular 
calendar, but not combined calendars.

Then I noticed that I could even do 
"month.php?cal=private/user1/privatecalendar" and the calendar would 
display, even though I was not authenticated (http basic). I assumed it 
would not display since trying to access it directly in a browser 
prompts for credentials.

Is there any way to have each user's public directory be the "root" as 
defined in the config.inc.php? I'm a little concerned about the private 
directory being readable through phpicalendar, but for now it's no big 
deal since I can just exclude it from the path.

Advice or suggestions are most welcome.

Thanks,
Todd

[PHPiCalendar-DEV] Debian Package

[<ms...@fr...>]

Has anyone expressed interest in maintaining a Debian PHPiCalendar 
package?

I've been happily using this package for a little while -

	http://cgi.sfu.ca/~jdbates/debian/pool/phpicalendar/

I need to sort out the PHP dependancy - & publishing support - but I 
was then considering submitting it to the Debian distribution.

What are your thoughts?

Thanks!
