Dear Yves Hoppe,

In Old Matukio I Could ad this code to: administrator\components\com_matukio\helper\util_event.php

To make a event unbookable to users that allready has a booked event at the same time, +/- 15 hours from the last bookes event and max 5 events Days in a row.

Where should i put my code now in the newer versioner to make the event unbookable in "Upcoming events and the new Bootstrap/Modern Template?

  $database->setQuery("SELECT MAX(end) FROM #__matukio, #__matukio_bookings Where userid='$usrid' And #__matukio.id = semid");



	$tempo = $database->loadResult();



$date1 = strtotime($tempo);

$date2 = strtotime($row->begin);



$hdiff = floor(($date2-$date1)/3600);

 $database->setQuery("SELECT MAX(begin) FROM #__matukio, #__matukio_bookings Where userid='$usrid' And #__matukio.id = semid");



	$tempo1 = $database->loadResult();



$date3 = strtotime($tempo1);

$date4 = strtotime($row->end);



$hdiff1 = floor(($date3-$date4)/3600);





if ($hdiff < '15' And $hdiff > '-15' OR $hdiff1 < '15' And$hdiff1 > '-15') {

        $buchbar = 1;

        $buchgraf = 0;

        $altbild = "Unbookable - EU's Working Time Directive, 2003/88/EC"; 

	 }



 $database->setQuery("SELECT begin FROM #__matukio, #__matukio_bookings Where userid='$usrid' And #__matukio.id = semid ORDER BY semid DESC LIMIT 6");

$eresult = $database->loadAssocList();



$edate1=strtotime($row->begin);

$edate2=strtotime($eresult['0']['begin']);

$edate3=strtotime($eresult['1']['begin']);

$edate4=strtotime($eresult['2']['begin']);

$edate5=strtotime($eresult['3']['begin']);

$edate6=strtotime($eresult['4']['begin']);

$edate7=strtotime($eresult['5']['begin']);





if (floor(($edate1-$edate2)/86400) < '2' AND floor(($edate1-$edate2)/86400) > '-2' AND floor(($edate2-$edate3)/86400) < '2' AND floor(($edate2-$edate3)/86400) > '-2' AND floor(($edate3-$edate4)/86400) < '2' AND floor(($edate3-$edate4)/86400) > '-2' AND floor(($edate4-$edate5)/86400) < '2' AND floor(($edate4-$edate5)/86400) > '-2' AND floor(($edate5-$edate6)/86400) < '2' AND floor(($edate5-$edate6)/86400) > '-2' AND floor(($edate6-$edate7)/86400) < '2' AND floor(($edate6-$edate7)/86400) > '-2') {

        $buchbar = 1;

        $buchgraf = 0;

        $altbild = "Unbookable - EU's Working Time Directive, 2003/88/EC"; 

	 }
