$defaults, DateFields with Silverstripe 2.4
28 May 2010 at 10:32pm
Hello,
I would like to set DateField default values (01/01/1900) but i can't : it's always the same date : 01/01/1970 !?
I try :
- 01/01/1900
- 1900/01/01
- 01-01-1900
- 1900-01-01
but nothing works :'(
Could you help me ? Thanks.
My code :
class Document extends Page {
static $db = array(
'Begin' => 'Date',
'End' => 'Date',
);static $defaults = array(
'Begin' => '01/01/1900',
'End' => '01/01/1900',
);function getCMSFields() {
$fields = parent::getCMSFields();$BeginField = new DateField('Begin', 'Begin'));
$EndField = new DateField('End', 'End'));$BeginField->setConfig('dmyfields', true);
$EndField->setConfig('dmyfields', true);$fields->addFieldToTab('Root.Content.Main',
new FieldGroup(
new LiteralField('Dates', 'Dates'),
new FieldGroup($BeginField, $EndField)
),
'Content'
);
return $fields;
}
} - 01/01/1900

From the PHP manual:
The valid range of a timestamp is typically from Fri, 13 Dec 1901 20:45:54 GMT to Tue, 19 Jan 2038 03:14:07 GMT. (These are the dates that correspond to the minimum and maximum values for a 32-bit signed integer). However, before PHP 5.1.0 this range was limited from 01-01-1970 to 19-01-2038 on some systems (e.g. Windows).
You may want to check:
1. Is the default obeyed for values after 1970?
2. Is your system running an old version of PHP?Cheers,

Thanks for your response.
I try :
static $defaults = array(
'Begin' => '1990-01-01',
'End' => '1990-01-01'
);and it works fine
Thanks.
But how can i have a date before 1970 ? I would like to have date like 1800, or 1900...
ps : my system :
- Debian Lenny (5.0.4)
- Apache 2 (2.2.9-10)
- PHP5 (5.2.6)
- MySQL Server 5 (5.0.51a)
- Silverstripe 2.4.0
- Debian Lenny (5.0.4)

I think i've found where the "problem" come from. In file sapphire/core/model/fieldtypes/Date.php, in setValue() method :
function setValue($value) {
// @todo This needs tidy up (what if you only specify a month and a year, for example?)
if(is_array($value)) {
if(!empty($value['Day']) && !empty($value['Month']) && !empty($value['Year'])) {
$this->value = $value['Year'] . '-' . $value['Month'] . '-' . $value['Day'];
return;
}
}// Default to NZ date format - strtotime expects a US date
if(ereg('^([0-9]+)/([0-9]+)/([0-9]+)$', $value, $parts)) {
$value = "$parts[2]/$parts[1]/$parts[3]";
}if(is_numeric($value)) {
$this->value = date('Y-m-d', $value);
} elseif(is_string($value)) {
$this->value = date('Y-m-d', strtotime($value));
}
}The use of
is a problem... I think i'll try to create a MyDate class 'extends Date ?) with the use of the new DateTime class of PHP 5.2+ to resolve my problem.date('Y-m-d', ... );
Or perhaps there is another solution ?
Thanks for your help !

If I set $defaults like this :
static $defaults = array(
'Begin' => array('Year' => '1900', 'Month' => '01', 'Day' => '01'),
'End' => array('Year' => '1900', 'Month' => '01', 'Day' => '01')
);it works because the date() fonction isn't use in setValue() :
function setValue($value) {
...
if(is_array($value)) {
if(!empty($value['Day']) && !empty($value['Month']) && !empty($value['Year'])) {
$this->value = $value['Year'] . '-' . $value['Month'] . '-' . $value['Day'];
return;
}
}
...
}but this doesn't resolve the problem when we change a date in the admin interface. I'll try my MyDate idea...

Ah, I didn't notice the strtotime() call before. That's the issue.
You may indeed have to extend Date, but this issue should be dealt with in the core, really. Thanks for raising this issue. Perhaps you'd like to make a bug report?
Thanks,
