I want to load default value for date. I added a plugin for


this is my code

public function aroundGetMetadataValues(
        SalesRuleValueProvider $subject,
        \Closure $proceed,
        Rule $rule
    ) {
        $result = $proceed($rule);
        $actions = &$result['actions']['children']['simple_action']['arguments']['data']['config']['options'];

            = '2014-09-01';
        return $result;

All other input field are working very well. I was able to pre populate it with a value except date. I tried all date format available, Any help on this


you can achieve this functionality below code.

UI component form in xml file like custom_form.xml:

<field name="your_field_id">
            <argument name="data" xsi:type="array">
                <item name="config" xsi:type="array">
                    <item name="class" xsi:type="string">{Vendorname}\{Modulename}\Ui\Component\Form\Element\Input</item>
                    <item name="dataType" xsi:type="string">text</item>
                    <item name="label" xsi:type="string" translate="true">End Date</item>
                    <item name="formElement" xsi:type="string">date</item>
                    <item name="source" xsi:type="string">customer</item>
                    <item name="sortOrder" xsi:type="number">89</item>                  
                   <item name="dataScope" xsi:type="string">your_field_id</item>
                   <item name="notice" xsi:type="string" translate="true">Enter the Account Removed Date of Customer(mm/dd/yyyy)</item>


Create file In {Vendorname}\{Modulename}\Ui\Component\Form\Element\Input.php

And add the logic in element Input.php file


    namespace {Vendorname}\{Modulename}\Ui\Component\Form\Element;

    class Input extends \Magento\Ui\Component\Form\Element\Input
         * Prepare component configuration
         * @return void
        public function prepare()

            $config = $this->getData('config');

            if(isset($config['dataScope']) && $config['dataScope']=='your_field_id'){
                $config['default']= date('Y-m-d', strtotime('+3 years'));
                $this->setData('config', (array)$config);

Please check and let know.

  • @soladogunilyasAdemuyiwa you're welcome :) – Ramki Nov 29 '18 at 9:11

You can try converting the date string to a date object like this:

$dateValue = '2011-03-05'
$value = date('Y-m-d', strtotime($dateValue));

And then add it as the value.

Not sure if it works.
