Well almost. I realised whilst trying to get to sleep last night that
there's a problem with this. In the first form you need:

$action = "form2.php";

$foo = $_POST['foo'];
$action = "results.php";

This way you won't get a circular dependency. However, it means that you'll
need to provide some other way of amending the details on form2 if it's a
requirement.

Maybe it thinks it's the letter O, have you tried using a font that puts a

RE: [PHP] How many Mondays in a month?
Funny you should ask this because I've been meaning to share some code that
I wrote a few months ago that does exactly this for any day of the week.
Please feel free to use this and make changes. I'd appreciate any
changes/bug fixes being sent back to me though.
"Monday",
"Tue" => "Tuesday",
"Wed" => "Wednesday",
"Thu" => "Thursday",
"Fri" => "Friday",
"Sat" => "Saturday",
"Sun" => "Sunday");
$month_array = array(1 => "Jan", "Feb", "Mar", "Apr", "May", "Jun",
"Jul", "Aug", "Sep", "Oct", "Nov", "Dec");
/*
* Check our arguments are valid.
*/
/*
* $day must be either a full day string or the 3 letter
abbreviation.
*/
if (!(in_array($day, $day_array) ||
array_key_exists($day, $day_array))) {
echo "num_days: invalid argument. \$day must be day name or
three letter abbreviation";
return;
}
/*
* $month must be either a full month name or its 3 letter
abrreviation
*/
if (($mth = array_search(substr($month,0,3), $month_array)) <= 0) {
echo "num_days: invalid argument. \$month must be month name
or three letter abbreviation";
return;
}
/*
* Now fetch the previous $day of $month+1 in $year;
* this will give us the last $day of $month.
*/
/*
* Calculate the timestamp of the 01/$mth+1/$year.
*/
$time = mktime(0,0,0,$mth+1,1,$year);
$str = strtotime("last $day", $time);
/*
* Return nth day of month.
*/
$date = date("j", $str);
/*
* If the difference between $date1 and $date2 is 28 then
* there are 5 occurences of $day in $month/$year, otherwise
* there are just 4.
*/
if ($date <= 28) {
return 4;
} else {
return 5;
}
}
?>
The other function I have does this:
/*
* nth_day
*
* A function that takes a number and a day and returns the date of
* nth occurrence of that day in the given month and year.
*
* Arguments:
* nth - the nth occurence required
* day - the day required
* month - which month are we talking about
* year - which year are we talking about
*
* Returns:
* date - the date on which the nth day occurs in month and year.
* or NULL for errors.
*/
Give me a shout if anyone wants this one.
Cheers, Greg.

Thanks, that's a good idea; though I would have to change my form
code to match:-(
When I make this change, where would be a good place to submit it?

I use it in a form that display checkboxes for each Sunday in a month. Someone else may use it by providing the arguments via a form in the manner you suggest.

The value can identify anything you like, on mine it identifies the domain the form was submitted from (though thinking about this now I can do this without a hidden value, but you get the idea!). The problem with this is that it means you have to have a separate copy of each form unless you can construct the hidden input value using other variables.

[PHP] Date Sorting
Apologies if this has been asked before but I couldn't find anything on google or any of the PHP code sites that quite fits my requirements. Here's the problem: I have a form which presents the user with a table of dates with checkboxes for a three month period, e.g. Dec 7th 14th21st28th am [ ] [ ] [ ] [ ] pm [ ] [ ] [ ] [ ] Jan 4th 11th18th25th am [ ] [ ] [ ] [ ] pm [ ] [ ] [ ] [ ] Feb 1st 8th 15th22nd29th am [ ] [ ] [ ] [ ] [ ] pm [ ] [ ] [ ] [ ] [ ] When the user submits the form with any of the boxes checked I want to have these sorted into date order. If I check Dec 28th am and pm, Jan 4th am and pm, Jan 18th am and pm and Feb 15th am and pm then the order returned in the _POST is: Dec 28 am, Dec 28 pm, Jan 4 am, Jan 18 am, Jan 4 pm, Jan 18 pm, Feb 15 am, Feb 15 pm This is, I believe, due to the order of the elements in the form. I tried using tabindex to influence the order returned but to no avail. So I'm now trying to do this in the php code that processes the submission. There is no year info such that I could turn the dates into timestamp and sort that way. Has anyone got any code that can sort this correctly?

How can I do that?
Use strtotime("last Friday");
