PHP CURL

Hi I want to post "events" to my DAViCal using .ICS file and PHP/CURL. Below is my code and seems like something wrong with it.

Or is there any other way to push events using .ICS to DAViCal?

Thanks.

$url = "http://my.davical.location/caldav.php/myusername/home/";
$ch = curl_init();
$localfile = "/my/ics/file/location/test.ics";
$fp = fopen ($localfile, "r");
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_USERPWD, 'myname:mypwd');
curl_setopt($ch, CURLOPT_HTTPHEADER, $header_array);
curl_setopt($ch, CURLOPT_PUT, 1);
curl_setopt($ch, CURLOPT_UPLOAD, 1);
curl_setopt($ch, CURLOPT_REFERER, 1);
curl_setopt($ch, CURLOPT_INFILE, $fp);
curl_setopt($ch, CURLOPT_INFILESIZE, filesize($localfile));
curl_exec($ch);

Hi,

This seems to be on the right track.

What's the content of $header_array ?

Having a CURLOPT_PUT seems a strange way to set the method though. Is
the library really that broken, or can you just specify the method by
name, somehow? How would one specify more obscure methods such as
MKCALENDAR, BIND or DELTICKET, for example?

DAViCal doesn't check the referrer header, and I'm not sure if
CURLOPT_UPLOAD is needed in this case - you might want to check that
one.

Cheers,
Andrew.

Re: PHP CURL

Hi Andrew,

Thanks for your reply, however I tried different combination and removing $header_array, CURLOPT_PUT, CURLOPT_UPLOAD and CURLOPT_REFERER but it didn't work.

But I was able to use this:
curl_setopt ($ch, CURLOPT_CUSTOMREQUEST, 'MKCALENDAR');
and successfully I was able to create new calendar.

So I tried playing around "curl_setopt ($ch, CURLOPT_CUSTOMREQUEST, 'PUT');", hoping that I can write .ICS thru 'PUT' but it was not successfull.

$url = "http://my.davical.location/caldav.php/myusername/home/";
$ch = curl_init();
$localfile = "/my/ics/file/location/test.ics";
$fp = fopen ($localfile, "r");
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_USERPWD, 'myname:mypwd');
curl_setopt($ch, CURLOPT_INFILE, $fp);
curl_setopt($ch, CURLOPT_INFILESIZE, filesize($localfile));
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'PUT');
$response = curl_exec($ch);
print_r($ch);
print_r($response);

SCREEN IS OUTPUT = "Resource id #371"

Any help on using 'PUT' and import .ICS is highly appreciated.

Thanks...

Your problems are here. The URL must contain a unique local URI.
A solution could be:
$filename = $url . sha1(date('U')) . sha1_file($localfile) . '.ics';
> curl_setopt($ch, CURLOPT_URL, $url);
And then replace:
curl_setopt($ch, CURLOPT_URL, $url);
with
curl_setopt($ch, CURLOPT_URL, $filename);
> curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'PUT');

Also using CURLOPT_CUSTOMREQUEST is not required. Using the above with:
curl_setopt($ch, CURLOPT_PUT, 1);
is sufficient.

I should have realised before... what you are very likely missing is
the "Content-type" header on your request. It should be set to
'text/icalendar'.

Good to know that you *can* do custom requests though :-)

Cheers,
Andrew.

Re: PHP CURL

Finally! This works...

Thanks Andrew & Michael.
@Andrew, I will try all custom request "caldav.php=>$request->method". I decided to use CURL because I can't get "$request->method['PUT']" worked.

$url = "http://my.davical.location/caldav.php/myusername/home/";
$localfile = "/my/ics/file/location/test.ics";
$filename = $url.sha1(date('U')).sha1_file($localfile).'.ics';
$header_array = array("Cache-Control: no-cache", "Content-type: text/icalendar");
$fp = fopen ($localfile, "r");
$ch = curl_init();
curl_setopt($ch, CURLOPT_VERBOSE, 1);
curl_setopt($ch, CURLOPT_URL, $filename );
curl_setopt($ch, CURLOPT_USERPWD, "myname:mypwd");
curl_setopt($ch, CURLOPT_HTTPHEADER, $header_array);
curl_setopt($ch, CURLOPT_UPLOAD, 1);
curl_setopt($ch, CURLOPT_PUT, 1);
curl_setopt($ch, CURLOPT_INFILE, $fp);
curl_setopt($ch, CURLOPT_INFILESIZE, filesize($localfile));
curl_exec($ch);
curl_close($ch);
fclose($fp);

Hi Andrew,

Just downloaded davical-0.9.9, and at /davical-0.9.9/htdocs/caldav.php
line #67 "case 'text/calendar':", does it matter between 'text/icalendar' as you had mentioned?

Thanks...

Sorry - I was running from memory, as fallibly as ever, I'm afraid.

If you read 'text/calendar' in the code that is the correct mime type.

Cheers,
Andrew.

Re: PHP CURL

Thanks Andrew. I got my PHP->CURL + DAViCal works!

However, I had some concerned. I had a Drag-Drop Calendar (JQuery+PHP+MySQL) base. And since I already had DAViCal works on my server I want to store all events to DAViCal DB (which is PostgreSQL). So instead of writing PostgreSQL Query (that includes converting my existing MySQL Queries to PG), I did use PHP CURL which works fine (so meaning "NO" PG & MySQL Query).

Now the issue is, on Drop event I only need to update the "dtstart" and "dtend" date. To do this I need the following:

1. GET event from DAViCal. (.ICS output)
2. Change the "dtstart" and "dtend" by manipulating that (.ICS output)
3. POST it back to DAViCal. (looks like creating another .ICS)

Does anybody had suggestion or shortcuts to this? I would like to avoid writing/creating an .ICS file.

Thanks in advance.
