Coding Help for Simplepie

Hi All,

 

Please excuse me in advance - I'm a bit of a noob.

 

I'm Using this code from http://james.cridland.net/code/google-calendar.html:

 

<?php

 

//v0.93: Added "make email addresses clickable". Thank you, Bjorn!

//v0.92: Fixed an issue with 'a section of dates' in amendable code. Thank you Kevin!

//v0.91: Nice error message if there are no events to display, requested by Tomas. Thanks!

//v0.90: Feature: clickable links in descriptions (start them http://). Thank you, Adam!

//      Feature: display end times, requested by Lucy. Thanks!

//      Feature: group by date, requested by Lucy. Thanks!

//      Note: I now use PHP5 - while this code should continue working in PHP4, beware!

For this page - http://electricspam.net/foyer/dah.php

 

It's basically reading from a Google calendar. I'm trying to get it to only read one day only (today), but I'm not having a lot of luck.

 

There's code there for it:

 

// Form the XML address.

$calendar_xml_address = "http://www.google.com/calendar/feeds/".$gmail."/public/full?singleevents=true&max-results=2500&futureevents=true&orderby=starttime";

 

// If you only want a section of dates - today only, for example, then try the following, which sets a maximum date to return. I've set this for a day from now.

// $calendar_xml_address = "http://www.google.com/calendar/feeds/".$gmail."/public/full?singleevents=true&start-min=".date("c")."&start-max=".date("c",strtotime("+1 day"));

 

but I just can't seem to get it to work. Does anyone here have any ideas?

 

Thanks in advance for any help.
