Wordpress Fonksiyonu is_page() ile kullanma

functions.php icinde WooCommerce eklentisine bağlı sekilde ürünler satin alınırken kullanıcıdan resim girişi istediği bir fonksiyon var fakat bu fonksiyonun sadece '1089' sayfa numaralı urun icin calismasini, digerlerinde resim girişinin olmamasını istiyorum. Kod su sekilde:

// Display additional product fields (+ jQuery code)

add_action( 'woocommerce_before_add_to_cart_button', 'display_additional_product_fields', 9 );

function display_additional_product_fields(){

  ?>

  <p class="form-row validate-required" id="image" >

    <label for="file_field"><?php echo __("Logonuzu Yukleyin") . ' '; ?>

      <br>

      <input type='file' name='image' accept='image/*'>

    </br>

    </label>

  </p>

  <br>

  <p>Ya da</p>

  </br>

  <?php

}

// Add custom fields data as the cart item custom data

add_filter( 'woocommerce_add_cart_item_data', 'add_custom_fields_data_as_custom_cart_item_data', 10, 2 );

function add_custom_fields_data_as_custom_cart_item_data( $cart_item, $product_id ){

  if( isset($_FILES['image']) && ! empty($_FILES['image']) ) {

    $upload   = wp_upload_bits( $_FILES['image']['name'], null, file_get_contents( $_FILES['image']['tmp_name'] ) );

    $filetype  = wp_check_filetype( basename( $upload['file'] ), null );

    $upload_dir = wp_upload_dir();

        $upl_base_url = is_ssl() ? str_replace('http://', 'https://', $upload_dir['baseurl']) : $upload_dir['baseurl'];

    $base_name  = basename( $upload['file'] );

    $cart_item['file_upload'] = array(

      'guid'   => $upl_base_url .'/'. _wp_relative_upload_path( $upload['file'] ), // Url

      'file_type' => $filetype['type'], // File type

      'file_name' => $base_name, // File name

      'title'  => ucfirst( preg_replace('/\.[^.]+$/', '', $base_name ) ), // Title

    );

    $cart_item['unique_key'] = md5( microtime().rand() ); // Avoid merging items

  }

  return $cart_item;

}

/*

// Display custom cart item data in cart (optional)

add_filter( 'woocommerce_get_item_data', 'display_custom_item_data', 10, 2 );

function display_custom_item_data( $cart_item_data, $cart_item ) {

  if ( isset( $cart_item['file_upload']['title'] ) ){

    $cart_item_data[] = array(

      'name' => __( 'Image uploaded', 'woocommerce' ),

      'value' => str_pad($cart_item['file_upload']['title'], 16, 'X', STR_PAD_LEFT) . '…',

    );

  }

  return $cart_item_data;

}

*/

// Save Image data as order item meta data

add_action( 'woocommerce_checkout_create_order_line_item', 'custom_field_update_order_item_meta', 20, 4 );

function custom_field_update_order_item_meta( $item, $cart_item_key, $values, $order ) {

  if ( isset( $values['file_upload'] ) ){

    $item->update_meta_data( '_img_file', $values['file_upload'] );

  }

}

// Admin orders: Display a linked button + the link of the image file

add_action( 'woocommerce_after_order_itemmeta', 'backend_image_link_after_order_itemmeta', 10, 3 );

function backend_image_link_after_order_itemmeta( $item_id, $item, $product ) {

  // Only in backend for order line items (avoiding errors)

  if( is_admin() && $item->is_type('line_item') && $file_data = $item->get_meta( '_img_file' ) ){

    echo '<p><a href="'.$file_data['guid'].'" target="_blank" class="button">'.__("Open Image") . '</a></p>'; // Optional

    echo '<p><code>'.$file_data['guid'].'</code></p>'; // Optional

  }

}

// Admin new order email: Display a linked button + the link of the image file

add_action( 'woocommerce_email_after_order_table', 'wc_email_new_order_custom_meta_data', 10, 4);

function wc_email_new_order_custom_meta_data( $order, $sent_to_admin, $plain_text, $email ){

  // On "new order" email notifications

  if ( 'new_order' === $email->id ) {

    foreach ($order->get_items() as $item ) {

      if ( $file_data = $item->get_meta( '_img_file' ) ) {

        echo '<p>

          <a href="'.$file_data['guid'].'" target="_blank" class="button">'.__("Download Image") . '</a><br>

          <pre><code style="font-size:12px; background-color:#eee; padding:5px;">'.$file_data['guid'].'</code></pre>

        </p><br>';

      }

    }

  }
