在 Woocommerce 中将结帐国家/地区下拉菜单设置为只读

I want country dropdown on woocommerce as readonly.

我已经将默认国家/地区设置为澳大利亚，但我希望它们是只读的。

Kashalo 的答案是正确的......您还可以使用其他多种方法之一：

1) 仅适用于结帐帐单国家/地区：

add_filter('woocommerce_checkout_fields', 'readdonly_billing_country_select_field');
function readdonly_billing_country_select_field( $fields ) {
    // Set billing and shipping country to AU
    WC()->customer->set_billing_country('AU');
    // Make billing country field read only
    $fields['billing']['billing_country']['custom_attributes'] = array( 'disabled' => 'disabled' );

    return $fields;
}

2) 仅适用于结帐和我的帐户帐单国家/地区：

add_filter('woocommerce_billing_fields', 'readdonly_billing_country_select_field');
function readdonly_billing_country_select_field( $fields ) {
    // Set billing and shipping country to AU
    WC()->customer->set_billing_country('AU');
    // Make billing country field read only
    $fields['billing_country']['custom_attributes'] = array( 'disabled' => 'disabled' );

    return $fields;
}

3 对于结帐帐单和送货国家/地区：

add_filter('woocommerce_checkout_fields', 'readdonly_country_select_field');
function readdonly_country_select_field( $fields ) {
    // Set billing and shipping country to AU
    WC()->customer->set_billing_country('AU');
    WC()->customer->set_shipping_country('AU');
    // Make billing and shipping country field read only
    $fields['billing']['billing_country']['custom_attributes'] = array( 'disabled' => 'disabled' );
    $fields['shipping']['shipping_country']['custom_attributes'] = array( 'disabled' => 'disabled' );

    return $fields;
}

4) 对于“结帐”和“我的帐户”帐单和送货国家/地区：

add_filter('woocommerce_default_address_fields', 'readdonly_country_select_field');
function readdonly_country_select_field( $fields ) {
    // Set billing and shipping country to AU
    WC()->customer->set_billing_country('AU');
    WC()->customer->set_shipping_country('AU');
    // Make country field read only
    $fields['country']['custom_attributes'] = array( 'disabled' => 'disabled' );

    return $fields;
}
