Problem changing date in calendar

[kumschick]

Hello there,

I have a BIG bug in my code! I can't find out where it comes from. Could someone help me please?

It's a calendar. You see the current date and when clicking on an other day of the week it should change the date, this works, BUT if you change the date again you don't geet the right day.

Could someone help me please? 😕

<?php

$get_day = date("N");
$get_date_day = date("d");
$get_date_mth = date("m");
$get_date_yea = date("Y");
if($getdate=="" | $getdate=="-1") {
  $set_day_bg['' . $get_day] = "bgcolor=\"$layout_list_color2\"";
}


if(empty($c)) {

  echo"Debug: IF THEN<br>";

  $get_date      = date("Y-m-d");
  $get_date_spec = explode("-",$get_date);
  $get_p_week = "0"; 
  $get_m_week = "0";

}
else {

  echo"Debug: ELSE<br>";

  $get_p_week = ($getdate+7); 
  $get_m_week = ($getdate-7); 

  $getweek       = time() + (($get_p_week) * 86400);
  $get_date      = date("Y-m-d",$getweek);
  $get_date_spec = explode("-",$get_date);

}


echo"
<table>
  <tr>
    <td><b>" . date("F d, Y", mktime (0,0,0,$get_date_spec[1],$get_date_spec[2],$get_date_spec[0])) . "</b>&nbsp;</td>
";

$i = 1;
$j = -$get_day;
while ($i <= 7):
   $j=$j+1;

   if(empty($c)) { $k = $get_p_week+$j-7; } else { $k = $get_p_week+$j-7; }

 echo"    <td " . $set_day_bg['' . $i] . "><a target=\"_self\" href=\"$PHP_SELF?getdate=$k&c=gw\">" . date("l", mktime (0,0,0,$get_date_mth,$get_date_day+$j,$get_date_yea)) . "</a></td>\n";
   $i++;
endwhile;

echo"
    <td><a target=\"_self\" href=\"$PHP_SELF?getdate=$get_m_week&c=gw\">&nbsp;-&nbsp;</a></td>
    <td><a target=\"_self\" href=\"$PHP_SELF?getdate=$get_p_week&c=gw\">&nbsp;+&nbsp;</a></td>
  </tr>
</table>
";

?>

There are a couple things:
1.) You rely on register_globals being on
[indent]This is a security risk, and in most server environments, it's off. This is now the default case in PHP 5 and above.[/indent]

2.) Why use a bitwise operator when comparing strings in your first if/i statement?
[indent]Or is to be "||" or "OR", not just one bar.
See the manual[/indent]

My guess is your errors come from your timestamp creation.
