如何为2种语言翻译文本字段woocommerce

Question

我有一个文本字段，我无法使用wpml进行第二语言的翻译。因此，我想为此添加一个代码。

我发现使用“ ICL_LANGUAGE_CODE”，但是我不确定如何将其用于数组。像下面这样使用并不会改变任何东西，仍然会显示两种语言的希腊文字。

    public function product_settings_fields() {
        echo '<div id="fees_product_data" class="fee_panel panel woocommerce_options_panel wc-metaboxes-wrapper">';
        echo '<div class="options_group">';


    if(ICL_LANGUAGE_CODE=='en') {// Text Field - Fee Name
        woocommerce_wp_text_input( array( 
        'id' => 'product-fee-name', 
        'label' => __( 'Recycling Tax', 'woocommerce-product-fees' ), 
        'data_type' => 'text', 
        'name' =>__( 'product-fee-name'), 
        'value'=>__('Recycling Tax'), 
        'placeholder' => __('Recycling Tax', 'woocommerce-product-fees'), 
        'desc_tip' => 'true', 
        'description' => __( 'This will be shown at checkout descriping the added fee.', 
        'woocommerce-product-fees' ) ) );

        // Text Field - Fee Amount
        woocommerce_wp_text_input( array( 
        'id' => 'product-fee-amount', 
        'label' => sprintf( __( 'Fee Amount (%s)', 'woocommerce-product-fees' ), get_woocommerce_currency_symbol() ), 
        'data_type' => 'price', 
        'placeholder' => __('Monetary Decimal or Percentage', 'woocommerce-product-fees'), 
        'desc_tip' => 'true', 
        'description' => __( 'Enter a monetary decimal without any currency symbols or thousand seperators. This field also accepts percentages.', 'woocommerce-product-fees' ) ) );}

        do_action( 'wcpf_add_product_settings_group_one' );

        echo '</div>';
        echo '<div class="options_group">';

    else(ICL_LANGUAGE_CODE=='gr'){woocommerce_wp_text_input( array( 
        'id' => 'product-fee-name', 
        'label' => __( 'Εισφορά Ανακύκλωσης', 'woocommerce-product-fees' ), 
        'data_type' => 'text', 
        'name' =>__( 'product-fee-name'), 
        'value'=>__('Εισφορά Ανακύκλωση'), 
        'placeholder' => __('Εισφορά Ανακύκλωση', 'woocommerce-product-fees'), 
        'desc_tip' => 'true', 
        'description' => __( 'This will be shown at checkout descriping the added fee.', 
        'woocommerce-product-fees' ) ) );

        // Text Field - Fee Amount
        woocommerce_wp_text_input( array( 
        'id' => 'product-fee-amount', 
        'label' => sprintf( __( 'Fee Amount (%s)', 'woocommerce-product-fees' ), get_woocommerce_currency_symbol() ), 
        'data_type' => 'price', 
        'placeholder' => __('Monetary Decimal or Percentage', 'woocommerce-product-fees'), 
        'desc_tip' => 'true', 
        'description' => __( 'Enter a monetary decimal without any currency symbols or thousand seperators. This field also accepts percentages.', 'woocommerce-product-fees' ) ) );}

        do_action( 'wcpf_add_product_settings_group_one' );

        echo '</div>';
        echo '<div class="options_group">';

我要完成的是针对希腊语言，文本字段应以希腊语显示文本，而对于英语语言，则应以英语显示文本。

提前谢谢！
