format() on a non-object

[Jakus]

I too am struggling with the same type of problem.

I am currently building a time sheet system for the company I work for.

My localhost (XAMPP) I am used to test the system has no problem with the code. On my webserver the following problem occurs:
"Fatal error: Call to a member function format() on a non-object in /usr/home/ubidjak/public_html/projectway/calDate.php on line 61"

line 61 is in function with the name increments the line is: "$beginDate = $begin->format("Y/m/d");"

$begin and $end is TimeDate objects.

Is there something I can do to fix it?

function increments( $begin, $end, $inc ) {
		$dates = array();
		$beginDate = $begin->format("Y/m/d");
		$endDate = $end->format("Y/m/d");

	$dayWeekStart = calDayWeek($beginDate);//call function (not shown)
	$dayWeekEnd = calDayWeek($endDate);//call function (not shown)

	$dayStart=$dayWeekStart[0];
	$weekStart=$dayWeekStart[1];
	$monthStart= ($begin->format(m))-1;
	$daysMonthStart = ($begin->format(d))-1;

	$beginTest = $beginDate;
	switch ($inc) {
		case "Weekly": $begin = $begin->modify("-$dayStart day"); break;
		case "Monthly": $begin = $begin->modify("-$daysMonthStart day"); break;
		case "Yearly": $begin = $begin->modify("-$daysMonthStart day"); $begin = $begin->modify("-$monthStart month"); break;
		default: break;
	}

	$date = $begin;
	while ( $date < $end ) {
		switch ($inc) {
			case "Overall": {
				$dates[] = $date->format("Y/m/d");
				$date = $end;
				$dates[] = $end->format("Y/m/d");
				break;
			}
			case "Daily": {
				$dates[] = $date->format("Y/m/d");
				$dates[] = $date->format("Y/m/d");
				$date = $date->modify("+1 day");
				break;
			}
			case "Weekly":  {
				$dates[] = $date->format("Y/m/d");
				$date = $date->modify("+6 day");
				$dates[] = $date->format("Y/m/d");
				$date = $date->modify("+1 day");
				break;
			}
			case "Monthly": {
				$dates[] = $date->format("Y/m/d");
				$date->modify("+1 month");
				$date->modify("-1 day");
				$dates[] = $date->format("Y/m/d");
				$date->modify("+1 day");
				break;
			}
			case "Yearly": {
				$dates[] = $date->format("Y/m/d");
				$date->modify("+1 year");
				$date->modify("-1 day");
				$dates[] = $date->format("Y/m/d");
				$date->modify("+1 day");
				break;
			}
			default: break;
		}

	}
	if ( $inc == "Daily" ) { $dates[] = $date->format("Y/m/d"); $dates[] = $date->format("Y/m/d"); }
	$dates[0] = $beginDate;
	$dates[count($dates)-1] = $endDate;
	return $dates;
}

Welcome to PHPBuilder! When posting PHP code, please use the board's [noparse]

..

[/noparse] bbcode tags as they make your code much easier to read and analyze. Also, please don't hijack others' threads with your own issues/problems/etc. - create a new one instead (as I've done for you). For reference, the previous thread can be found here.

Apparently no, they aren't (as per the error message).

You've shown us the function definition, but you haven't shown us how you attempt to actually use this function. So, can you show us that code as well?

[Jakus]

This would be an example how I use the function:

if ( isset ($POST['startYear']) ) $startYear = $POST['startYear']; else $startYear = 2011;
$startYear = $startYear+1-1;
$startMonth = $POST['startMonth'] +1-1;
$startDay = $POST['startDay'];
$startDate = new DateTime();
$startDate = $startDate->setDate($startYear, $startMonth, $startDay);

if ( isset ($POST['endYear']) ) $endYear = $POST['endYear']; else $endYear = 2011;
$endMonth = $POST['endMonth'];
$endDay = $POST['endDay'];
$endDate = new DateTime();
$endDate->setDate($endYear, $endMonth, $endDay);

$increments = $_POST['increments'];
include_once('calDate.php'; //function increments is in calDate.php
$dates = increments($startDate, $endDate, $increments);

[bradgrafelman]

Just before the function call to increments(), place the following code:

echo "<pre>";
var_dump($startDate); echo "\n";
var_dump($endDate);
echo "</pre>";

and show us the output.

(In case you're unaware, [man]var_dump/man is an excellent way to determine exactly what a variable contains.)

On my localhost:

object(DateTime)#2 (3) {
["date"]=>
string(19) "2011-01-03 13:22:59"
["timezone_type"]=>
int(3)
["timezone"]=>
string(15) "Europe/Helsinki"
}

object(DateTime)#3 (3) {
["date"]=>
string(19) "2011-08-03 13:22:59"
["timezone_type"]=>
int(3)
["timezone"]=>
string(15) "Europe/Helsinki"
}

On my webserver:

NULL

object(DateTime)#2 (0) {
}

What version of PHP is your remote webserver running?

Also, can you add a:

print_r($_POST);

to the output and show us what your script is receiving as executed on the remote webserver?

[Jakus]

remote server, php version 3.3.0

for the print_r($_POST);
"Array ( [projectID] => Array ( [0] => 8 ) [submittedB] => TRUE [startDay] => 3 [startMonth] => 0 [startYear] => 2011 [endDay] => 3 [endMonth] => 7 [endYear] => 2011 [increments] => Overall [optional] => Optional view )"

[Derokorian]

I think you have an error in your version number, as according to php.net that version never existed.

The last PHP 3 release (3.0.18) was made on October 20, 2000.

Sorry its 5.2.17
