can't make a link with $_server

[tomboy78]

I run win xp, apache 1.3 and php 4.3.2. I made a calendar which works fine but the links to next and previous month.

I dont get any errors, it just doesnt work. it looks right in the url as well. eg: month=2&year=2003, when trying to move from january to february.

I think this part is the problem:
<a href="'.$SERVER['PHP_SELF'].'?month=%d&year=%d">%s</a>';
print '"'.$SERVER['PHP_SELF'].'?month=%d&year=%d">%s';

here is some of the code:

[code=php]

<?php
function pc_calendar($month, $year, $opts = '') {
    //set default options  //
    if (! is_array($opts)) {
         $opts = array(); 
    }
    if (! isset($opts['today_color'])) { 
        $opts['today_color'] = '#FFFFoo'; 
    }
    if (! isset($opts['month_link'])) {
        $opts['month_link'] =
//THIS IS WHERE THE PROBLEM IS I BELIEVE        

'<a href="'.$_SERVER['PHP_SELF'].'?month=%d&year=%d">%s</a>';
    print '"'.$_SERVER['PHP_SELF'].'?month=%d&year=%d">%s';
    }

list($this_month,$this_year,$this_day) = split(',',strftime('%m,%y,%d'));
$day_highlight = (($this_month == $month) && ($this_year == $year));

list($prev_month,$prev_year) = 
    split(',',strftime('%m,%Y',mktime(0,0,0,$month-1,1,$year)));
$prev_month_link = sprintf($opts['month_link'],$prev_month,$prev_year,'&lt;');

list($next_month,$next_year) =
    split(',',strftime('%m,%Y',mktime(0,0,0,$month+1,1,$year)));
$next_month_link = sprintf($opts['month_link'],$next_month,$next_year,'&gt;');



?>
<form name="form1" method="post" action="index.php">
<table border="0" cellspacing="0" cellpadding="2" align="center">
        <tr>
            <td align="left"><font size="5">
                <?php print $prev_month_link ?>
            </font></td>
            <td colspan="5" align="center"><font size="5">
                <?php print strftime('%B %Y',mktime(0,0,0,$month,1,$year)); ?>
            </font></td>
            <td align="right"><font size="5">
                <?php print $next_month_link ?>
            </font></td>
        </tr>
  <?php

so are you telling us that when you click on it, in the url it shows:

www.domain.com/pageyouwant.php?month=2&year=2003

cuz if it does, then you are likely having problems getting the info from the query string, you may have to use $GET['month'], and $GET['year'] to access your variables

[tomboy78]

yes, the url shows that. more specifically: http://localhost/pc_calendar.php?month=3&year=2003

So the link should work is just that when clicking the link it doesn't give the next value (eg. next month) when it reloades the page so you're probably right there.

The problem could be in these lines:

[code=php]

list($prev_month,$prev_year) = 
		split(',',strftime('%m,%Y',mktime(0,0,0,$month-1,1,$year)));
	$prev_month_link = sprintf($opts['month_link'],$prev_month,$prev_year,'<');

list($next_month,$next_year) =
	split(',',strftime('%m,%Y',mktime(0,0,0,$month+1,1,$year)));
$next_month_link = sprintf($opts['month_link'],$next_month,$next_year,'>');

I just don't see where where I can use post/get to access the new variables. any ideas?

[stolzyboy]

well where do you grab the values from the query string to use them to get the next and prev months etc...
