ical to mysql - hair pulling stuff!

[SetToLoki]

Hey all

I am trying to take calendar info from an ical sheet and store it into a database.

 

I have done this to a certain extent but it is causing me many issues.

I started by getting each event in the ical sheet and stored them in an array

 

Example Array

Array
(
    [begin] => VEVENT
    [prodid] => -//Kerio Technologies//Kerio MailServer//EN
    [method] => PUBLISH
    [version] => 2.0
    [x-version-kms] => 6.2.0
    [x-calendarserver-access] => PUBLIC
    [tzid] => Dublin, Edinburgh, Lisbon, London
    [dtstart] => 19810329T010000
    [tzoffsetto] => +0100
    [tzoffsetfrom] => +0000
    [rrule] => FREQ=YEARLY-BYMONTH=3-BYDAY=-1SU
    [end] => VCALENDAR
    [dtstamp] => 20090703T091907Z
    [uid] => 7d593fe6-0a7d-4a82-bd1a-11a6f9276e4c
    [sequence] => 0
    [summary] => Problems Log
    [location] => Intranet
    [dtstart;tzid="dublin, edinburgh, lisbon, london"] => 20090703T103000
    [dtend;tzid="dublin, edinburgh, lisbon, london"] => 20090703T110000
    [class] => PUBLIC
    [priority] => 5
    [transp] => OPAQUE
    [x-microsoft-cdo-busystatus] => BUSY
    [x-label] => 0
    [description] => If event is deleted in Kerio it doesnt get deleted from 
    [ database.\n\nideas for fix] =>  \\nCron
    [ ntries against the event array.\nif row exists in table but not in array dele] => 
    [ te the row. \nwill need to loop through each row and check it against array. ] => 
    [ this could be a long process, test speeds.] => 
)

 

then I tried to enter each section of the array into a field in my database.

 

Code

foreach ( $events as $k => $event ) { //Loop through event
		$sEvent = $event['data'];
		$BlowUp = explode("\n", $sEvent);
		$e = array();

		foreach($BlowUp as $Data)  //Loop Through Event
		{
			$str = array(";");
			$rpl = array("-");
			$sRoffle = explode(":", $Data);
			$key = strtolower($sRoffle[0]);
			$data = mysql_escape_string(str_replace($str, $rpl, $sRoffle[1]));
			//$TempArray = array($key => $data);
			$e[$key] = $data;
		}
		// check data for empty fields
		if (!isset($e['uid'])){$e['uid'] = "null";}
		if (!isset($e['rrule'])){$e['rrule'] = "null";}
		if (!isset($e['summary'])){$e['summary'] = "null";}
		if (!isset($e['class'])){$e['class'] = "null";}
		if (!isset($e['description'])){$e['description'] = "null";}
		if (!isset($e['priority'])){$e['priority'] = "null";}
		if (!isset($e['x-microsoft-cdo-busystatus'])){$e['x-microsoft-cdo-busystatus'] = "null";}
		if (!isset($e['x-label'])){$e['x-label'] = "null";}
		if (!isset($e['dtstart;tzid="dublin, edinburgh, lisbon, london"'])){$e['dtstart;tzid="dublin, edinburgh, lisbon, london"'] = "null";}
		if (!isset($e['dtend;tzid="dublin, edinburgh, lisbon, london"'])){$e['dtend;tzid="dublin, edinburgh, lisbon, london"'] = "null";}
		if (!isset($e['dtstamp'])){$e['dtstamp'] = "null";}
		if (!isset($e['tzid'])){$e['tzid'] = "null";}
		if (!isset($e['location'])){$e['location'] = "null";}

		if(isset($e['dtstart;value=date'])){
			$e['dtstart;tzid="dublin, edinburgh, lisbon, london"'] = $e['dtstart;value=date'];
			$e['dtend;tzid="dublin, edinburgh, lisbon, london"'] = $e['dtend;value=date'];
		}
		//print_r($e);
		//$fields = "UID, rrule, summary, class, description, priority, xmicrosoftcdobusystatus, xlabel, dtstart, dtend, dtstamp, tzid, location";

		$values[] = "('".$e['uid']."','"
		.$e['rrule']."','"
		.$e['summary']."','"
		.$e['class']."','"
		.$e['description']."','"
		.$e['priority']."','"
		.$e['x-microsoft-cdo-busystatus']."','"
		.$e['x-label']."','"
		.$e['dtstart;tzid="dublin, edinburgh, lisbon, london"']."','"
		.$e['dtend;tzid="dublin, edinburgh, lisbon, london"']."','"
		.$e['dtstamp']."','"
		.$e['tzid']."','"
		.$e['location']."','1')";

				//Insert data into database
		$db1 = new MySQL($db_host, $db_user, $db_pass, $db_name);

		$sql1  = "INSERT INTO cal_events ";  
		$sql1 .= "(class, description, dtend, dtstamp, dtstart, id, location, priority, rrule, summary, tzid, UID, xlabel, xmicrosoftcdobusystatus) ";
		$sql1 .= "VALUES ";
		$sql1 .= "('".$e['class']."','".$e['description']."','".$e['dtend;tzid="dublin, edinburgh, lisbon, london"']."','".$e['dtstamp']."','".$e['dtstart;tzid="dublin, edinburgh, lisbon, london"']."','".$account['id']."','".$e['location']."','".$e['priority']."','".$e['rrule']."','".$e['summary']."','".$e['tzid']."','".$e['uid']."','".$e['x-label']."','".$e['x-microsoft-cdo-busystatus']."')";
		$sql1 .= "ON DUPLICATE KEY UPDATE ";
		$sql1 .= "class=VALUES(class), description=VALUES(description), dtend=VALUES(dtend), dtstamp=VALUES(dtstamp), dtstart=VALUES(dtstart), id=VALUES(id), location=VALUES(location), priority=VALUES(priority), rrule=VALUES(rrule), summary=VALUES(summary), tzid=VALUES(tzid), xlabel=VALUES(xlabel), xmicrosoftcdobusystatus=VALUES(xmicrosoftcdobusystatus)";

		if($results = $db1->query($sql1))
		{
			$string = date("d/m/Y H:i s")." :: calsync.php :: Affected Rows ".$db1->affected_rows($results)." \r\n";
			$File = "cron.txt"; 
			$Handle = fopen($File, 'a+');
			fwrite($Handle, $string); 
			fclose($Handle);
		}
		else
		{
			$string = date("d/m/Y H:i s")." :: calsync.php :: ERROR ".$db1->error." \r\n";
			$File = "cron.txt"; 
			$Handle = fopen($File, 'a+');
			fwrite($Handle, $string); 
			fclose($Handle);					
		}

 

now this work fine, though long winded

the problem I am having is when you come to events like description

 

[description] => If event is deleted in Kerio it doesnt get deleted from 
    [ database.\n\nideas for fix] =>  \\nCron
    [ ntries against the event array.\nif row exists in table but not in array dele] => 
    [ te the row. \nwill need to loop through each row and check it against array. ] => 
    [ this could be a long process, test speeds.] => 

 

As you can see each new line of the description is put into a new block how can I find and restore this info and put it into database, also if anyone can  be bothered reading and giving me examples of how to optimize the code that reads the array and stores it to database, I will reward you with a cookie!

How are you populating the array?
