||||||| Recursive Variable ????

Gary_Kambic

Hello,

I have a variable that is being sent from one php page to another and then displayed. The problem is that the information disappears after someone changes the month on the calendar php function. The variable name is $link which is displayed in blue on the schedule.php page. Apparently this action is resetting the $link variable information.

Is their anyway to roll this $link info over when they change the month on the calendar (after executing the calendar php function?)

Thanks for the assist, Gary

To view, go here first and click "schedule an appointment"

http://www.tnevni.com/4_timber_ridge_lane/information.php

Code for schedule.php follows:

<html>
<title>Tnevni | Schedule Appointment</title>
<body>
<form method="POST" action="../schedule_appointment.php">

...

...

include("miniCalendarClass.php");
$calendar = new miniCalendar('schedule.php',$d,$m,$y);
$calendar->buildMiniCalendar(80,80,$sc, $bc, $hc);

...

</tr>
</table>
<?php
$listing = $_POST['listing'];
echo $listing;
?>

</form>
</body>
</html>

------------------------------- from miniCalendar function
<?php
class miniCalendar
{
var $day;
var $month;
var $year;
var $link;

	function miniCalendar($link, $day = "", $month = "", $year = "")
	{
		if($day == 0 && $month == 0 && $year == 0)
		{
			$this->day = date("d");
			$this->month = date("n");
			$this->year = date("Y");
		}

If you want to pass a var onto the next page from a link (I'm guessing a link is what the user clicks to pick a different month) then you need to build it into the get url string you're using there.

If this string picked the next month:

http://server.com/file.php?month=Jan

You'd need to add the $link var on the end, so it looks like this:

http://server.con/file.php?month=Jan&link=Hudson+Valley

I stated the wrong variable. The varibale I'm trying to pass is $listing. $link is the page that where the calendar is located so when executed it returns to the $link page, in this case it is schedule.php.

The information I'm trying to pass to schedule.php each time miniCalendarClass.php is executed is $listing (originally sent by ...information.php, see URL in previous message)

Sorry about the confusion.

Any thoughts?

Thanks, Gary

Hi,

you can modify the constructor of you class to

function miniCalendar($link, $listing, $day = "", $month = "", $year = "") {

and add var $listing; to the global variables of your class.

Then modify the part in you class that assembles the forward/backward links and add the $listing variable (urlencoded).
You can then use that get parameter to display the link if someone follows the forward/backward links.

kevinsequeira

gary,
let me explain what the issue is.
1. when you select a date in the next month using the arrow link in the calendar, the page refreshes because of the link.
2. so when this happens variable $listing is not present in the link that minicalendar generates.
3. so you can pass it where you call the function
$calendar = new miniCalendar('schedule.php',$d,$m,$y);
like this
$calendar = new miniCalendar('schedule.php?listing='.$listing,$d,$m,$y);

but this will screw up the link generated inside minicalender php page cause the calendar link is of this form

/schedule.php?hc=%230080ff&bc=%23eeeeee&sc=orange&d=28&m=6&y=2003

so the url then will become
/schedule.php?listing=whatever?hc=%230080ff&bc=%23eeeeee&sc=orange&d=28&m=6&y=2003

so you will have two ? in the url which will be wrong.

so u need to check if ? is present in the link and make changes to the minicalendar code.

STEP 1 :

$extra_link ="?listing=<?php print($listing);?>";
$extra_link = urlencode($extra_link);
$link = "schedule.php".$extra_link;
include("miniCalendarClass.php");
$calendar = new miniCalendar($link,$d,$m,$y);

STEP 2 :
BACK UP minicalendar.php
in miniCalendar.php after this line
$currenttime = mktime(0,0,0,$this->month, $this->day, $this->year);
$output = "<table border='0' cellpadding='2' cellspacing='0' width='$width' height='$height'>";

replace

$output .= "<tr height='20' valign='center'><td align='center'><a href='".$this->link."?hc=".urlencode($headerColor)."&bc=".urlencode($bgColor)."&sc=".urlencode($selectedDayColor)."&d=$pday&m=$pmonth&y=$pyear' class='navi'><img src='images/left_black.gif' border='0'></a></td><td align='center' valign='middle' class='title'>".date("M Y",$currenttime)."</td><td align='center' class='navi'><a href='".$this->link."?hc=".urlencode($headerColor)."&bc=".urlencode($bgColor)."&sc=".urlencode($selectedDayColor)."&d=$nday&m=$nmonth&y=$nyear'><img src='images/right_black.gif' border='0'></a></td></tr><tr><td colspan='3' bgcolor='$bgColor'><table border='0' cellpadding='2' cellspacing='2' width='100%' bgcolor='$bgColor' height='100%'>";

with

$output .= "<tr height='20' valign='center'><td align='center'>";

if(strstr($this->link,"?")){
$output .="<a href='".$this->link."&hc=".urlencode($headerColor)."&bc=".urlencode($bgColor)."&sc=".urlencode($selectedDayColor)."&d=$pday&m=$pmonth&y=$pyear' class='navi'>";
}else{
$output .="<a href='".$this->link."?hc=".urlencode($headerColor)."&bc=".urlencode($bgColor)."&sc=".urlencode($selectedDayColor)."&d=$pday&m=$pmonth&y=$pyear' class='navi'>";
}

$output .="<img src='images/left_black.gif' border='0'></a></td><td align='center' valign='middle' class='title'>".date("M Y",$currenttime)."</td><td align='center' class='navi'>";

if(strstr($this->link,"?")){
$output .="<a href='".$this->link."&hc=".urlencode($headerColor)."&bc=".urlencode($bgColor)."&sc=".urlencode($selectedDayColor)."&d=$nday&m=$nmonth&y=$nyear'>";
}else{
$output .="<a href='".$this->link."?hc=".urlencode($headerColor)."&bc=".urlencode($bgColor)."&sc=".urlencode($selectedDayColor)."&d=$nday&m=$nmonth&y=$nyear'>";
}

$output .="<img src='images/right_black.gif' border='0'></a></td></tr><tr><td colspan='3' bgcolor='$bgColor'><table border='0' cellpadding='2' cellspacing='2' width='100%' bgcolor='$bgColor' height='100%'>";

u might get syntax errors cause i havent checked the code but that shouldnt be a problem to solve.

Kevin,

schedule.php executes fine with the $listing displayed. When I try to change the date I receive a 404 Server Error = Page Not Found, then it goes to my default web host page. thx gary

// START THE CALENDAR SECTION//
$sc = "orange"; //this is today's color
$bc = "#eeeeee"; //this is the background color
$hc = "#0080ff"; //this is the header color

$extra_link = urlencode($extra_link);
$link = "schedule.php".$extra_link;

hm , time to debug 😃

in schedule.php type this

echo $link;

before this

include("miniCalendarClass.php");

and in miniCalendarClass.php type this

echo $this->link;

before this line

$currenttime = mktime(0,0,0,$this->month, $this->day, $this->year);

what do u get

EDIT : change this
$extra_link .="?listing=<?php print($listing);?>";

to

$extra_link ="?listing=".$listing;

Kevin,

I changed the one statement at the bottom of your last message and received this:

Not Found
The requested URL /schedule.php?listing=http://www.tnevni.com/4_timber_ridge_lane/information.php was not found on this server.

I'll insert the other stuff now.

Gary_Kambic

schedule.php%3Flisting%3Dhttp%3A%2F%2Fwww.tnevni.com%2F4_timber_ridge_lane%2Finformation.php

output from the statements you requested when I execute schedule.php

kevinsequeira

ok,
i was looking at the URL in my browser at the same time, just remove this line in schedule.php

$extra_link = urlencode($extra_link);

i will take a look on the site directly if its not working and get back to you

reg

kevinsequeira

looks like its working..

Hi Kevin,

Yes it does work great. Thank you!

One thing you may not have noticed though when you get the schedule.php page with the calendar opened, click on "Today: 28 May 2003" just beneath the calendar. This is suppose to take you back to the current month. It does, but look at the $listing URL in blue, it has attached some code to the end of the string.

Is it possible to check that condition?

Thanks again for a wonderful job,

Gary

kevinsequeira

same check as before

change this

$output .= "</tr></table></td></tr><tr><td colspan='3' align='center' class='day'>Today : <a href='".$this->link."?hc=".urlencode($headerColor)."&bc=".urlencode($bgColor)."&sc=".urlencode($selectedDayColor)."&d=".date("d")."&m=".date("n")."&y=".date("Y")."'>".date("d M Y")."</a></td></tr></table>";

if(strstr($this->link,"?")){
$output .= "</tr></table></td></tr><tr><td colspan='3' align='center' class='day'>Today : <a href='".$this->link."&hc=".urlencode($headerColor)."&bc=".urlencode($bgColor)."&sc=".urlencode($selectedDayColor)."&d=".date("d")."&m=".date("n")."&y=".date("Y")."'>".date("d M Y")."</a></td></tr></table>";
