Help please with list of events script

[Justin_Diamond]

Hi there,

I am trying to write a 'list of events' script.

Basically I want to list up and coming events and when those events have passed I want them hidden.

I am currently using this:

<?php
$date = date("Ymd");

$handle=opendir('events');
while (($file = readdir($handle))!==false) {

if ($file >= $date) {
   include("events/$file");
}
}
closedir($handle); 
?>

Very basic I know - but could you tell me how to add a line that tells the user if there are no events at present. So if all current events pass it just says 'Sorry, no events are planned at present'

The script works though calling dated txt files in YYYYMMDD format.

I hope you can help 🙂 or maybe you have a better solution.

Thanks a lot
Justin

One way could be:

<?php
$date = date("Ymd");
$NumEvents=0;
$handle=opendir('events');
while (($file = readdir($handle))!==false) {

if ($file >= $date) {
   include("events/$file");
   $NumEvents=$NumEvents + 1;
}
}
closedir($handle); 

if($NumEvents GT 0)
  {
   echo "$NumEvents were found";
  }
else
  {
  echo "Sorry, no events are planned at present";
  }

?>

Hi Leatherback,

Many thanks for that 🙂

It did create a parser error on this line:

if($NumEvents GT 0) 

Not sure why though.

Thanks again
Justin

Ok,

Sorry about htat. Seems like PhP doesn't accept the GT. (I mostly program in IDL, which uses different opreators).

Try using > instead of GT

You'll need to think a little too.

The correction to be made should be obvious, since you know exactly which line is it on.

Think a little bit more on what is wrong with:

$NumEvents GT 0

Leatherback,

That did it - thank you!

I agree with what you said Laserlight - I have been delving into PHP recently and have found it hard going sometimes.

I really appreciate the help that these forums provide.

Thank you again.

Sorry about this - this is a follow-on to the first question.

Could somebody offer any advice on how to adjust this script to allow for derver time difference?

I am in the U.K. and my Server is in U.S.A. - adifference of +7 hours.

Any advice would be greatly appreciated.

Thank you

Hi,

Have a loko at the manual. There is load of functions to manipulate time-strings.
Just do a search for time and date

Hi there,

I think I have got it.

If I stick this at the top of my page I think this will move the time forward:

<?php
$hourdiff = "7"; // hours difference between server time and local time
$timeadjust = ($hourdiff * 60 * 60);
$servdate = date("l, d F Y h:i a",time() + $timeadjust);
?>

Thank you
