PrestaShop 1.7.5订单商品消息区域对应的TPL物理文件位置咨询及UTF-8显示问题修改需求

Hey there! I’ve tackled similar encoding glitches in PrestaShop before, so let’s walk through how to resolve this for you:

Locate the Correct TPL Files #

The product message section you’re targeting lives in different templates depending on where you’re viewing the order:

• Back Office (Admin Order Details)
  The template file you need is:
  admin/themes/default/template/controllers/orders/_product_line.tpl
  Look for lines rendering the product message—you’ll probably see something like {$product.message} here, which is the code outputting the text in your red-circled area.

• Front Office (Customer Order Details)
  If customers also see this encoding issue, check your active theme’s template:
  themes/[your-active-theme-name]/templates/order-details-product-line.tpl
  Search for the variable displaying the product message (often {$product.message} or {$item.message}).

Fix the UTF-8 Encoding Problem #

Once you’ve found the relevant line, use PrestaShop’s built-in filter to enforce proper UTF-8 rendering:
Replace the raw variable (e.g., {$product.message}) with:

{convertEncoding $product.message 'UTF-8'}

This ensures the content is parsed and displayed in UTF-8, which should fix the display anomalies you’re seeing.

A couple extra checks to make sure the issue doesn’t come back:

• Verify the TPL file itself is saved with UTF-8 encoding (without BOM)
• Confirm the message field in the ps_order_detail database table uses a UTF-8 collation (like utf8mb4_unicode_ci)
