Magento 2: How to submit custom html content from ui_form to controller?

Question

I am developing a module using ui_form. I have developed ui_form and on submit it post all fields except custom html fields.

For example:

<container name="pl_labelposition" >
        <argument name="data" xsi:type="array">
            <item name="config" xsi:type="array">
                <item name="sortOrder" xsi:type="number">30</item>
                <item name="label" xsi:type="string" translate="true">Label Position</item>
            </item>
        </argument>
        <htmlContent name="html_content">
            <argument name="block" xsi:type="object">Company\Module\Block\Adminhtml\ProductLabel\Edit\LabelPosition</argument>
        </htmlContent>
    </container>

I also use conditions of sales rules:

        <container name="conditions_apply_to" >
        <argument name="data" xsi:type="array">
            <item name="config" xsi:type="array">
                <item name="sortOrder" xsi:type="number">10</item>

            </item>
        </argument>
        <htmlContent name="html_content">
            <argument name="block" xsi:type="object">Magento\SalesRule\Block\Adminhtml\Promo\Quote\Edit\Tab\Conditions</argument>
        </htmlContent>
    </container>

Could you help me to resolve this problem? I am not able to submit such fields to controller. How can i use in controller?

Help will be appreciated

Thank You in Advance

Answer 1

In your block create

protected $_template = 'Company_Module::labelposition.phtml';

now, make labelposition.phtml and add your html field with attribute data-form-part="formname".

Here the formname must be name of your uiform like <uiComponent name="product_form"/>.

e.g.

<input type="text" data-form-part="product_form" name="test" value="Hello World">

You will get the value of this field.
