How to use if(is_page()) for WooCommerce products?-CodePudding

I'm using a code in functions.php which allows users to send their logo for a customizable product. I want to use this function only for this page because the other product is non-customizable. At first I tried it like:

if(is_page('1089')){
   \\function here
}

However, whenever I use this or is_post etc. image input button completely disappears from both of the products. Can you help me about this? The function I'm using is:

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

function display_additional_product_fields(){
     ?>
  <p  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
}
}
}

    $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;

CodePudding user response：

You can check for the product id like this:

if(get_the_id() == 1089){
   //Your logic here
}

However, I would recommend you do this in a different way like maybe creating a dedicated category for those products, that way you can add more products later to have the same functionality and also if you ever delete that product and create a new one you don't need to touch the code again to add the id but just assigning the product to the dedicated category. Then your condition will be like:

if(has_term('special_category_slug', 'product_cat', get_the_id())){
  //Your logic here
}
