Add a terms and conditions checkbox in Woocommerce

问题:

In woocommerce registration form, there's no "terms and conditions" before sign up button.

Is there a way to make it appears in the form?

Here is the link of my theme layout.

If not done yet, first you need enable terms and conditions on checkout page:

1. To create a new page in Wordpress for your terms and conditions
2. To enable that page in Woocommerce > Settings > Checkout > Checkout pages (section):
   
3. Then save… you are done.

The code to get the term and conditions check box on registration form:

// Add term and conditions check box on registration form
add_action( 'woocommerce_register_form', 'add_terms_and_conditions_to_registration', 20 );
function add_terms_and_conditions_to_registration() {

    if ( wc_get_page_id( 'terms' ) > 0 && is_account_page() ) {
        ?>
        <p class="form-row terms wc-terms-and-conditions">
            <label class="woocommerce-form__label woocommerce-form__label-for-checkbox checkbox">
                <input type="checkbox" class="woocommerce-form__input woocommerce-form__input-checkbox input-checkbox" name="terms" <?php checked( apply_filters( 'woocommerce_terms_is_checked_default', isset( $_POST['terms'] ) ), true ); ?> id="terms" /> <span><?php printf( __( 'I&rsquo;ve read and accept the <a href="%s" target="_blank" class="woocommerce-terms-and-conditions-link">terms &amp; conditions</a>', 'woocommerce' ), esc_url( wc_get_page_permalink( 'terms' ) ) ); ?></span> <span class="required">*</span>
            </label>
            <input type="hidden" name="terms-field" value="1" />
        </p>
    <?php
    }
}

// Validate required term and conditions check box
add_action( 'woocommerce_register_post', 'terms_and_conditions_validation', 20, 3 );
function terms_and_conditions_validation( $username, $email, $validation_errors ) {
    if ( ! isset( $_POST['terms'] ) )
        $validation_errors->add( 'terms_error', __( 'Terms and condition are not checked!', 'woocommerce' ) );

    return $validation_errors;
}

Code goes in function.php file of your active child theme (or active theme). Tested and works.

When checkbox is not ticked, an error message is displayed.

This checkbox is only a validation step (It is not saved in database, as we don't use that information anywhere).

Addition:

To allow terms and conditions only in Registration page use one of the following:

add_filter( 'woocommerce_checkout_show_terms', '__return_false' );

Or

add_filter( 'woocommerce_get_terms_and_conditions_checkbox_text', '__return_false' );

Code goes in function.php file of your active child theme (or active theme). Tested on WC 3.5+ and works.
