[SOLVED] $_get

[adam291086]

Say i have a webpage with the url adamplowman.co.uk. If a user clicks on next the url goes to adamplowman.co.uk?m=1. Now if m is there i want to run some script, That i can do.

 

But how do i get it to say if m isn't there then run this script??

 

 

[matstuff]

if (!isset($_GET['m'])) {

  do stuff...

}

Thanks, Works great.

 

The problem i am now facing is that when i set the url to what i want it returns an odd result.

 

<a href="<?php echo $_SERVER['PHP_SELF']; ?>?m=<?php echo $nextmonth; ?>?y=<?php echo $thisyear; >">Adam</a></th>

 

Whats happening is

when i echo

$_GET['m']

i just get the result 1 which is correct. But when i echo

$_GET['y']

i get the result ?=2008. I dont want the ?= and just 2008.

You have to use & if you want more than 1 ID in the URL.

[adam291086]

is this right?

 

<a href="<?php echo $_SERVER['PHP_SELF']; ?>?m=<?php echo $nextmonth; ?>&y=<?php echo $thisyear;?>">Adam</a></th>

[trq]

Yes. Test it and see.

ok all is working well aprt from this. In my claedar i have a next button.

 

//next month
$nextmonth = $thismonth+1;
if($nextmonth >12)
{
$thisyear = date('Y')+1;
$nextmonth = "1";
}

 

problem being when i get to december 2008 and click next it says january 2008 again. This is due to %thisyear being taken from the current year. How do i get around this and make it say january 2009.

 

 

[revraz]

Maybe something along the lines that if current month = Dec, then the next year will be +1

[adam291086]

i have done this but still getting the same result

 

if ($monthname == "December")
{
$thisyear+1;
}

 

$monthname is set in the script and return the month name correctly.

[revraz]

Dont you want something to  = $thisyear + 1?

 

$thisyear += 1 ?

[adam291086]

edit..... just fixed it with

//next month
$nextmonth = $thismonth+1;
if($nextmonth >12)
{
$thisyear= $thisyear+1;
}

[revraz]

I was just pointing out that $thisyear+1; doesn't do anything by itself.

[adam291086]

yeah i realised that after you said it. Thanks

[revraz]

FYI, short version of

 

$thisyear= $thisyear+1;

 

is

 

$thisyear += 1;

ok now i have created a previuos button, problem is that. When i get to january 2009 and click previous i get dec 2008, which is correct. When i click previous again i get nov 2009. Can anyone see why.

 

<?php
//previous month
$premonth =$thismonth-1;
if($premonth <1)
{
$thisyear = $thisyear-1;
$premonth = '12';
}
?>
  <a href="<?php echo $_SERVER['PHP_SELF']; ?>?m=<?php echo $premonth; ?>&&y=<?php echo $thisyear;?>">Previous Month</a>

 

just edit the english and the date part

[revraz]

YOu have two && in your URL code, not sure if that's effecting it or not.

[boushley]

Wouldn't you want to check if $premonth is <= 0... I mean if you have a 12th month, then you can't have a 0th month.

[adam291086]

either way works. But i am still getting the same problem.

[PHP_PhREEEk]

Just popping in to advise you on building the dynamic URL. & should be replaced with & in all places used. The exception would be header() URLs, etc., but definitely any hyperlinks should be & if you want your HTML to validate.

[adam291086]

thanks, any idea why the previous part wont work?

[fanfavorite]

That is fine, must be something in your other code.  Are you setting thisyear = $_GET[y]?   

[PHP_PhREEEk]

It's not working because you haven't fully grasped how to use date() and mktime() in combination to create a dynamic selector. You'll just need to keep playing with it. Go to php.net and look up the functions:

date

mktime

strtotime

strftime

 

The most important part here is, read through the User comments and pick up little bits of code advice through their examples. In many cases, through the user comments, you will see that particular function used just about every creative way possible. But keep trying... all of this learning to use time and date functions is extremely valuable, and many otherwise really good coders unfortunately never git 'r done.

Try this to get you started:

 

$month = $_GET['m'];

$year = $_GET['y'];

 

$next = mktime(0,0,0,$arr_month[$month]+1,1,$year);

$next = $_SERVER['PHP_SELF']."?m=".date("F", $next)."&y=".date("Y", $next);

 

$prev = mktime(0,0,0,$arr_month[$month]-1,1,$year);

$prev = $_SERVER['PHP_SELF']."?m=".date("F", $prev)."&y=".date("Y", $prev);
