Undefined variable complicated :-(

madspof · May 20, 2009

Hi everyone I have been trying to get a calendar entry system to work with error reporting on but to no avail, the problem lies in the part of highlighted below. And for some reason it tells me that it is undefined and no matter what ive tried i cannot get it to be define. anyway here is a the code below and here is a link to the effect script www.deskfun.co.nr/1123 hooton park squadron/calendar/ you will need to use the username: Testing and password: squadron. Its line 226 which brings the error message up

Sorry about the large amount of code but i dont know which part of it is affecting it :-(

and thanks before hand :-)

What's the error message?

madspof · May 20, 2009

its a notice and this "Notice: Undefined index: $thisDate in C:\Deskfun\1123 Hooton park website\calendar\myEventsCalendar.php on line 226"

Ken2k7 · May 20, 2009

224     $thisDate = $thisMonth . "-" . $thisDay . "-" . $thisYear;
226     if($this->eventsId[$thisDate]) {

Those are 2 lines I copy and pasted. I assume the array eventsId does NOT have an index at $thisDate.

Here's something you can do to debug - after line 224, put this

var_dump($thisDate);
var_dump($this->eventsId);

madspof · May 20, 2009

Ok now im getting this

string( "5-1-2009" array(1) { ["5-20-2009"]=>  int(2) }
Notice: Undefined index: 5-1-2009 in C:\Deskfun\1123 Hooton park website\calendar\myEventsCalendar.php on line 227

absolutly no idea at this lol oh and that dump changes for each day but you can see that if you go on the page

Ken2k7 · May 20, 2009

Well you know the problem now. Your $thisDate is set to the string "5-1-2009" and your array only has "5-20-2009".

madspof · May 20, 2009

Right well im no good at arrays how would i go about fixing this?

thanks

pcw · May 20, 2009

Could this be used in this script?

Here is the link to my topic

madspof · May 20, 2009

Im not sure :s i realy do not know what to do with this i dont understand the way in which the

 
$this->eventsId[$thisDate]

bit works with teh -> so ive got no hope at figuring out how that output from the var dump is going to help me lol

Ken2k7 · May 20, 2009

madspof - read up on PHP OOP.

madspof · May 20, 2009
