Hello I created a basic calendar where the admin can put in events. I’m new to php so I used a tutorial for the beginning.
The view of the calender is realy simply:
ma di wo do vr za zo
1 2 3 4 5 6 7
…
If there’s an event, the date becomes blue. But I wont to change the calendar; if there’s an event the title must be seen in the calender itself instead of under the calender. I hope you understand 
Can someone help me? Here is the code!
<html>
<head>
<div id="kalender">
<h1> Kalender </h1>
<p> Klik op een blauwe datum om de details weer te geven </p>
<script>
function goLastMonth(month, year){
if(month == 1) {
--year;
month = 13;
}
--month
var monthstring= ""+month+"";
var monthlength = monthstring.length;
if(monthlength <=1){
monthstring = "0" + monthstring;
}
document.location.href ="<?php echo $_SERVER['PHP_SELF'];?>?month="+monthstring+"&year="+year;
}
function goNextMonth(month, year){
if(month == 12) {
++year;
month = 0;
}
++month
var monthstring= ""+month+"";
var monthlength = monthstring.length;
if(monthlength <=1){
monthstring = "0" + monthstring;
}
document.location.href ="<?php $_SERVER['PHP_SELF'];?>?month="+monthstring+"&year="+year;
}
</script>
