Can't set datetime field time value in API

[adrian]

Hi everyone,

I am trying to add a datetime field to a process module and am having a weird problem here. This is my code:

$f = $this->modules->get("InputfieldDatetime");
$f->name = 'changes_since';
$f->label = 'Changes since';
$f->datepicker = 3;
$f->attr('data-dateformat', "yy-mm-dd");
$f->attr('data-timeformat', "h:mm tt");
$f->attr('value', "2014-03-13 1:45 pm");
$f->attr('class', 'FieldtypeDatetime');
$form->add($f);

When this field is displayed the value is just: 2014-03-13. For some reason the time is missing.

However, when I use the datetime picker a make a selection, the field is then populated with the full date and time.

Not that it helps, but if I change the field type to InputfieldText, the full date time is shown when the input renders.

Also, something else weird I noticed is that when I submit the form, $input->post returns the correct date and time, but 

$form->processInput($this->input->post);
echo date("Y-m-d g:m", $form->get('changes_since')->value);

returns: "2014-03-13 12:03", no matter what time I select. I think this is to do with the am/pm in the time format.

If I compare the generated classes, ids, etc for this input field vs one in the admin when editing a page, they are the same so I am currently at a loss.

Thanks for any help!

Some progress. Adding:

$f->attr('dateInputFormat', "Y-m-d");
$f->attr('timeInputFormat', "g:i a");

populates the time as well, but it is always 12:00 am, ignoring what is set in the value.

I'll keep experimenting and report back.

EDIT: Ok, I got it - you need to set the value to the unix timestamp

Final code:

$f = $this->modules->get("InputfieldDatetime");
$f->name = 'changes_since';
$f->label = 'Changes since';
$f->datepicker = 3;
$f->attr('data-dateformat', "yy-mm-dd");
$f->attr('data-timeformat', "hh:mm:ss");
$f->attr('dateInputFormat', "Y-m-d");
$f->attr('timeInputFormat', "H:i:s");
if($form->get('changes_since')->value){
    $f->attr('value', $form->get('changes_since')->value);
    $f->attr('data-ts', $form->get('changes_since')->value);
}
$f->attr('class', 'FieldtypeDatetime');
$form->add($f);

Just only need

$f->dateInputFormat = "Y-m-d";
$f->timeInputFormat = "H:i:s";

the attr(key,value) is for html attributes and data-dateformat will get written by the inputfield automaticly.

Oh and field name would be a attr

$f->attr("name", "myname");

Something like this works perfectly.

$f = $modules->InputfieldDatetime;
$f->label = "MyDate";
$f->attr("name+id", "mydate");
$f->dateInputFormat = "Y-m-d";
$f->timeInputFormat = "H:i:s";
$f->attr("value", time());
echo $f->render();

Thanks Soma,

That is certainly cleaner and simpler

Only thing I needed to add back in was:

$f->datepicker = 3;

And in case someone is wondering about the 3:

https://github.com/ryancramerdesign/ProcessWire/blob/03387f8283d518e9cc405eff8f05cd6a5bf77c4c/wire/modules/Inputfield/InputfieldDatetime/InputfieldDatetime.module#L24

const datepickerNo = 0; // no datepicker
const datepickerClick = 1; // datepicker on click
const datepickerInline = 2;  // inline datepicker, always visible (no timepicker support)
const datepickerFocus = 3;  // datepicker on field focus

I ended up in one of those situations where I was trying to add attributes to match the generated source of a working datetime field, rather than figuring out exactly what PW needed to set them itself.

Can I blame it on the fact that it was 1 am
