10月CMS创建一个多选表单字段

如果您有能力触摸内核并添加内容，则可以更好地构建窗口小部件或进行拉取请求 \模块\后端\ widgets \ form \部分中的相同内容带名称_field_dropdownlist.htm

然后在\modules\backend\widgets\form\Form.php第630行更改：

将您的部分名称添加为_field或.htm前_field_dropdownlist.htm成为dropdowList

现在在您的yaml文件中使用类型：dropdownList，它将起作用。

I need to create a multi select form field in October Cms backend form (fields.yaml). I applied the following method

select_field: label: Sample type: dropdown attributes: {multiple:'multiple'}

Options to this field will be invoked from the model

Everything is working good but when i submit the form only the first selected option is being inserted as JSON data in the database table text field. I want every selected option to be stored. I have also declared the field as Jsonable in model ie., protected $jsonable = ['field_name'];

Note : When I use type as checkboxlist it is working as I thought but I don't want it to be checkboxlist. I'm new to October cms is there any easy way..

you can't use a dropdown field with mutiple value because it was made to handle single value. as the checkbox and radio this is why there are checkboxList(i guess).

But i found a solution. Use a partial as field type in fields.yaml instead of dropdown

octobercms/docs/backend/forms#field-partial

Create a partial with the content below (notice the [] in name attribute this is why it work !)

But be aware that this is just a trick and you can only use direct yaml options assignment octobercms/docs/backend/forms#field-dropdown

And for the yaml

A better approche would be may be to build a widget or make a pull request if you have the ability you can touch the core and add

the same content in \modules\backend\widgets\form\partials with name _field_dropdownlist.htm

then in \modules\backend\widgets\form\Form.php line 630 change :

to add your partial name without _field or .htm ex _field_dropdownlist.htm become dropdowList

now in your yaml file juste use type:dropdownList and it will work.
