Hi,

I am in the process of adding a new type of form field (Select Dynamic) to my web page in order to let a customer pick from list products in the database in the contact form.

For a test I would just like to replicate the functionality of the static Select field, so what I do is I subscribe to the contentManagement.collectFieldTypes event in my plugin and create a new field type, in this way:



For now the SelectDyn class just consists of inheriting everything from Select class:



The problem I get is that $options does not contain index "values" and thus the drop-down field is empty even though my class does absolutely nothing else except inherits from "Select". The entered values of my SelectDyn field however do get saved in the database and when editing a form they get correctly loaded with the ipWidgetIpForm_InitListOptions Javascript function.

I can't quite figure out the mechanism to debug this error further, can anyone point me in the right direction? I'm using IP 2.2.

Thanks and best regards,
Roman

Constructor gets the data that has been returned by JS function ipWidgetIpForm_SaveListOptions.

But if you want to populate select with products from database, you don't need "options" next to your input. That means you can skip last tree parameters in field initialization:

$newFieldType = new \Modules\standard\content_management\FieldType('IpSelectDyn', '\Modules\CustomFormFields\SelectDyn', $typeSelect . " dynamic");


And get data from database in the constructor:

public function __construct($options = array()) {
$options = data from DB in the way \Modules\developer\form\Field\Select expects it
parent::__construct($options);
}

Hello, thank you for your answer - the problem I have is that the ipWidgetIpForm_SaveListOptions function does indeed return data, but the constructor does not receive it. Maybe it has something to do with inheriting my field from Select class and not from Field class.

Anyway, halfway through my debugging I have realized just as you have suggested, shunned the "Options" and filled in my values from the DB in the constructor. This is pretty much the result I was going for, but I wanted to make it a bit more universal, i.e. I wanted to specify the table and the value fields of the in the "Options" for the field and not have one custom class for each dropdown from Db (Products, People, ...).

Best regards,

Ok. I know why your options values were not passed to the constructor.

Look at this line:

$newFieldType = new \Modules\standard\content_management\FieldType('IpSelectDyn', '\Modules\CustomFormFields\SelectDyn', $typeSelect . " dynamic", 'ipWidgetIpForm_InitListOptions', 'ipWidgetIpForm_SaveListOptions', \Ip\View::create('view/form_field_options/list.php')->render());
$event->addField($newFieldType);

You need to extend: \Modules\standard\content_management\FieldType and use your extended class in this line.

Overwrite "createField" function in the way you need for your field to work.
