I am trying to add Captcha inside product review form. For that i add

<referenceContainer name="form.additional.info">
            <block class="Magento\Captcha\Block\Captcha" name="captcha" after="-" cacheable="false">
                <action method="setFormId">
                    <argument name="formId" xsi:type="string">user_login</argument>
                </action>
                <action method="setImgWidth">
                    <argument name="width" xsi:type="string">230</argument>
                </action>
                <action method="setImgHeight">
                    <argument name="width" xsi:type="string">50</argument>
                </action>
            </block>
        </referenceContainer>
        <referenceBlock name="head.components">
            <block class="Magento\Framework\View\Element\Js\Components" name="captcha_page_head_components" template="Magento_Captcha::js/components.phtml"/>
        </referenceBlock>

<?php echo $block->getLayout()->getBlock('form.additional.info')->toHtml(); ?> But after that no captcha is showing in the review form. Please help me to do it. Thanks

Answer 1

To use google reCaptch : Go to Admin -> Store -> Configuration -> Security Tab -> Google reCaptcha -> Frontend -> Enabled = Yes

Use in Review = select Yes

Add getChildHtml('form.additional.info') ?> in your theme's Magento_Review /templates/form.phtml file.

Answer 2

To add google reCaptcha in the product review form please check the following steps:

• Step 1: Go to Admin > Stores > Settings > Configuration > Security Tab > Google reCaptcha Storefront
• Step 2: Fill out the section of reCAPTCHA type(s) as per your requirement, you can check about this in detail from https://docs.magento.com/user-guide/stores/security-google-recaptcha.html
• Step 3: From Storefront section, uncheck the Use system value checkbox for Enable for Product Review location field and set it to the reCAPTCHA type that you have configured in the last step.
• Step 4: After Completion, Save Config and Check.
• Magento 2 have added 'recaptcha' block in 'product.review.form.fields.before' container of product review form's block and it's called from \vendor\magento\module-review\view\frontend\templates\form.phtml file as 'getChildHtml('form_fields_before') ?>'
