calling a function with a mouse click

bong_ripper

This is my problem, I have a schedule web page, and i want the user to be able to browse through the different days using previous and next day hyperlinks. I wrote a simple function that should change the day according to a mouse click, but i don't know how to call the function from within the anchor tags. I know this must sound like a total newbie question, but PLEASE help mne!!!

<?php
$day = date("d");
$month = date("m");
$year = date("y");
$date = "$month-$day-$year";
$dayofweek = date("l");
function previous(){
$day = --$day;
$day = date("d", mktime(0,0,0,$month,$day,$year));
$date = "$month-$day-$year";
return $date;
}
echo $date;
?>

the url to the test site is:
http://www.macktree.com/times/
thanks in advance

The only way I have found to call a function like this is.....

if($action == "previous")
{
previous();
}

and then make a link like so...

<a href=\"$PHPSELF?action=previous\">Previous</a>

Hope this helps

Thaks Jeff,
It helped me out somewhat, but I still need more help.. I was thinking about using a form and processing it on that page or maybe creating another page that i can send a variable to .... i don't know.. i am frustrated.

Hey, how bout I just change the SQL statement so that it looks for a different day? This is a schedule that uses MySQL after all... I think i may be stuck with the same dilema though... calling that damn function from an anchor tag... why can't this be as easy as JavaScript?

Your trying to do this the hard way. When the page is generated with a day then create a variable giving the value for one day less and for one day more. then you can use hyperlinks to pass this variable to pass this variable to your new pages. Example:- http://www.macktree.com/times.index.php?day=$dayless

I hate to admit it, but I am still having a hard time even getting that to work.. what is happening is that it will now just default to the day less variable.... I am pretty frustrated because I could easily do this in VB 6.0 and Access 2000.... I just want a button that will change the SQL statement!!!!!!!
(Thanks Anyway)
