index undefined

[Stickybomb]

ok i am working on a simple event system, bsically i pass the information from the database to an array for a given month then use the array to wirte the events. for some reason though i am getting index undefined for each day

 

heres the code i am using to create the array

 

$vEvent = array();
$vD = array();
$vM = array();
$vY = array();
$vId = array();
$vTitle = array();

$i=0;
while($row = mysql_fetch_array($vResults)){

$vD[$i]=$row['event_day'];
$vM[$i]=$row['event_month'];
$vY[$i]=$row['event_year'];
$vId[$i]=$row['event_id'];
$vTitle[$i]=$row['event_title'];

$i++;
}

$y=1;
for($i=1;$i<=$days['mday'];$i++){

$vEvent[$i] = '<ul>';

for($x=0;$x<sizeof($vD);$x++){

	if($vY[$x]==$vYear && $vM[$x]==$vMonth && $vD[$x]==$i){

		$vEvent[$i].='<li>';
		$vEvent[$i].='<a href="" onclick="event-'.$y.'.style.visibility=\'visible\';">';
		$vEvent[$i].=$vTitle[$x];
		$vEvent[$i].='</a>';
		$vEvent[$i].='</li>';
		$y++;

	}

}

$vEvent[$i] .= '</ul>';

}

 

i can not seem to figure this one out any help is greatly appriciated thnks sticky

which line gives u the error?

[Stickybomb]

the error is when i am trying to read the value stored in the array basically i just use a for loop to go through each day of the month and pass the array value for that day to a variable to be echoed like this

 

$vCalendar = $vEvent[$i]

 

it is giving me an undefined offset:1,2,3... error for each value of $i 1-30 or however many days in that month

I see the code where you set everything up, but I don't see the code where you use it. Please post that code.

this is the entire code

 

//calendar write function
//$vResults = the results from the events query
//$vMonth = month to print
//$vYear = year to print
//creates th calendar then returns the code
function fWriteCalendar($vResults,$vMonth,$vYear){
$vCalendar=array();
    // Get key day informations. 
    // We need the first and last day of the month and the actual day
    $today  = getdate();
    $temp1 = getdate(mktime(0,0,0,$vMonth,1,$vYear));
    $temp2 = getdate(mktime(0,0,0,$vMonth+1,0,$vYear));
    $temp3 = getdate(mktime(0,0,0,$vMonth,1,$vYear));
    $introoffset = $temp1['wday'];
    $closeoffset = $temp2['wday'];
    $days=$temp2['mday'];
    $month=$temp3['month'];

    $actday = 1;
    
//get event data
$vEvent = array();
$vD = array();

You are accessing a variable that isn't set you have 2 options.

1. Code for notices (meaning code in a way as to prevent notices from happening)

2. Turn them off

error_reporting(E_ALL ~ notices);

That should turn off notices and only show all the other standard errors.

 

Notices are small issues, and small things.  you would be wise to try coding with them, so you can avoid major mistakes, it takes a little extra time but it's worth it later when you learn how to naturally avoid them,and you will have more reliable, more server portable code when everything is done.
