I have this ui-component definition of a form field In my Magento 2 module.

    <field name="name">
        <argument name="data" xsi:type="array">
            <item name="config" xsi:type="array">
                <item name="dataType" xsi:type="string">text</item>
                <item name="label" xsi:type="string" translate="true">Some Label</item>
                <item name="formElement" xsi:type="string">input</item>
                <item name="source" xsi:type="string">something_here</item>
                <item name="sortOrder" xsi:type="number">10</item>
                <item name="dataScope" xsi:type="string">name</item>
                <item name="notice" xsi:type="string" translate="true">Enter something here</item>
                <item name="validation" xsi:type="array">
                    <item name="required-entry" xsi:type="boolean">true</item>

and I'm trying to make it readonly. Not disabled. Just readonly.
I tried adding:

<item name="readonly" xsi:type="boolean">true</item>  

to the config section, but obviously I failed.
How can I make the field readonly? Can I make the field readonly?

  • What a difference between parameters "disabled" and "readonly"? In my opinion both parameters works in a similar way. – Siarhey Uchukhlebau Oct 14 '16 at 10:29

    From what I know, disabled means the field is not sent via post and readonly is sent. My plan is to modify the value of the readonly field via some javascript. – Marius Oct 14 '16 at 10:34
  • Sure, but in regular magento form (not ui) the "readonly" attribute means the html-attribute "disabled". In other way you should use a custom component or a custom script, becouse the "readonly" attribute nonexists for the ui-components. – Siarhey Uchukhlebau Oct 14 '16 at 10:44
  • I'm just going to stick with your answer now. I just hope I don't actually need to make a field disabled in the future. – Marius Oct 14 '16 at 10:49
  • Leave formElement as input and add text elementTmpl like this <item name="elementTmpl" xsi:type="string">ui/form/element/text</item> Refer: magento.stackexchange.com/a/296735/14271 – Magento_Newbie Feb 29 '20 at 1:12

Try to add the disabled parameter to the element like this:

<field name="is_active">
    <argument name="data" xsi:type="array">
        <item name="config" xsi:type="array">
            <item name="label" xsi:type="string">Status</item>
            <item name="dataType" xsi:type="string">number</item>
            <item name="formElement" xsi:type="string">checkbox</item>
            <item name="source" xsi:type="string">vendor_rules_rule_form.vendor_rules_rule_form_data_source.is_active</item>
            <item name="prefer" xsi:type="string">toggle</item>
            <item name="disabled" xsi:type="boolean">true</item>
            <item name="valueMap" xsi:type="array">
                <item name="true" xsi:type="string">1</item>
                <item name="false" xsi:type="string">0</item>
            <item name="sortOrder" xsi:type="number">12</item>

Result should be similar with the readonly parameter for the regular form element:

    I'm puzzled here. it works, but it looks wrong to me. If the field is disabled how come is still sent via POST? Anyway, this is a different question. I'll take this for granted for now. – Marius Oct 14 '16 at 10:34

    @Marius This is most likely because when a form is submitted from the backend, it's not the actual form that is submitted but a new form with hidden fields that is created when you click save. The form is created according to the fields in your UI Components XML-file and fields that are marked with data-form-part. Take a look at module-ui/view/base/web/js/form/form.js::initConfig(), validate() and submit(). Also look at lib/mage/utils/misc.js::submit(). These combined add a new form at the end of the body that is actually submitted. – Giel Berkers Jan 16 '17 at 14:00
  • @GielBerkers. I've done some research after asking this question and I came to the same conclusion as you explained. You are right. The submitted data does not come from a form. – Marius Jan 16 '17 at 14:07
  • I also have to same like issue.. I want to enable price field for configurable product.. Here I have explained link – gks Apr 26 '17 at 13:33
