Hi,

In my DB have table:

CREATE TABLE `lekarze_grafik` (
	`id_lekarze_grafik` INT(11) NOT NULL AUTO_INCREMENT,
	`id_lekarza` VARCHAR(5) NULL DEFAULT NULL,
	`id_grafik_dzien_tygodnia` INT(11) NULL DEFAULT NULL,
	`godz_poczatek` DATETIME NULL DEFAULT NULL,
	PRIMARY KEY (`id_lekarze_grafik`),
	UNIQUE INDEX `id_lekarze_grafik` (`id_lekarze_grafik`)
)

Example data in that table:
1, L1PN, 1, 1900-01-01 13:00:00
2, L2PN, 1, 1900-01-01 08:00:00
3, L2PN, 2, 1900-01-01 10:00:00
4, L2PN, 3, 1900-01-01 12:00:00
5, L2PN, 4, 1900-01-01 14:00:00
6, L2PN, 5, 1900-01-01 18:00:00


On my form I have two drop down list named: lekarze_dd and gwn_dd.
Also have datepicker dzien_wizyty_nfz_dp with format Y-m-d

In lekarze_dd drop down list have example values:
L1PN=Lekarz1
L2PN=Lekarz2

To lekarze_dd is connected Event with options:
On: !=
Action: Set Dynamic Options
field id: gwn_dd
Options list or ajax event: gwn_db

In event gwn_db i have two elemets:
1. DB read where:
- Table name: lekarze_grafik
- Model ID: gwn_db_read
- Fields: id_lekarza,id_grafik_dzien_tygodnia,godz_poczatek
- Conditions:

<?php

return array('id_lekarza' => $form->data["lekarze_dd"],'id_grafik_dzien_tygodnia' =>date( "w", strtotime($form->data["dzien_wizyty_nfz_dp"])));

?>

2. Custom code:

<?php
$gwn_db = array();

foreach ( $form->data['gwn_db_read'] as $v ) {

$gwn_db[$v['godz_poczatek']] = $v['godz_poczatek'].'-'.$form->data["dzien_wizyty_nfz_dp"];

}

echo json_encode($gwn_db);
?>

The problem is in DB read element with datepicker condition.
There are no Values in drop down gwn_dd.

For example when I change conditions to this:

return array('id_lekarza' => $form->data["lekarze_dd"],'id_grafik_dzien_tygodnia' => 3);

Values in drop down gwn_dd are OK.

It looks like in condition to $form->data["dzien_wizyty_nfz_dp"] is not pass the value from datepicer.

Instead datepicker for this condition I've also tried to use another drop down list named dzien_wizyty_nfz_dd with values:
1=2014-06-02
2=2014-06-03
3=2014-06-04
4=2014-06-05
5=2014-06-06

That I was sure the values for second condition are good.
In condition for gwn_db I put:

<?php

return array('id_lekarza' => $form->data["lekarze_dd"],'id_grafik_dzien_tygodnia' => $form->data["dzien_wizyty_nfz_dd"]);

?>

Still no result.

Hi trafas,

You can try to check the executed AJAX call in the FireBug console window and run it in your browser to check how it works, and maybe debug it.

Thanks for reply.
I tried FireBug and looks that my first conclusions were hit in ten.

FireBug generate link with all parameters submitted in GET method.
In GET link there is no parameter dzien_wizyty_nfz_dp.

Thanks,
Work perfectly
