Add Custom Validation Street Address Field in backend Magento 2

Question

I Want To Set Minimum Length Value For Street Address Field On Admin Side

I want to set min_text_length = 5 For Street Address Field In Customer Address Form

I am Trying To Update Attribute but Not Working

public function upgrade(ModuleDataSetupInterface $setup, ModuleContextInterface $context)
    {
        if (version_compare($context->getVersion(), '1.0.1', '<')) {
            $customerSetup = $this->customerSetup->create(['setup' => $setup]);
            $customerSetup->addAttribute(
                'customer_address',
                'street',
                [
                    'type' => 'static',
                    'label' => 'Street Address',
                    'input' => 'multiline',
                    'backend' => \Magento\Eav\Model\Entity\Attribute\Backend\DefaultBackend::class,
                    'sort_order' => 70,
                    'multiline_count' => 4,
                    'validate_rules' => '{"max_text_length":255,"min_text_length":5}',
                    'position' => 70,
                ]
            );
        }
    }

In Database Already Set {"max_text_length":255,"min_text_length":5} But Validation not Working

Note :- Admin Side Not Frontend Side.

Answer 1

You Can do it by Script and update validation within it.You have to change

'validate_rules' => '{"max_text_length":255,"min_text_length":5}',

You can change it directly from DB you have to do it carefully.

• Open table eav_attribute and find attribute_code street and get attribute_id from it (generally attribute_id is 28).

• Open table customer_eav_attribute and find that attribute_id (28 in my case). update in validate_rules column {"max_text_length":255,"min_text_length":5}

• Now it is done in admin

  

Note: You have to remove if it occurs in front

Answer 2

i am not sure if this works

<rule name="required-entry" xsi:type="boolean">true</rule>

Example from first name

<field name="city" formElement="input">
        <argument name="data" xsi:type="array">
            <item name="config" xsi:type="array">
                <item name="source" xsi:type="string">address</item>
            </item>
        </argument>
        <settings>

remove this validation

            <validation>
                <rule name="required-entry" xsi:type="boolean">true</rule>
            </validation>

up to here

            <dataType>text</dataType>
        </settings>
    </field>

You can do this from the admin (Magento 2.3.3):
