在Sailthru开发HTML邮件：如何将商品标题截断至15字符并添加省略号？

Hey there! I see you're trying to implement title truncation for product titles in your Sailthru HTML emails—let's get this sorted out for you.

First, let's break down the issues with your current code:

• You’re using slice(content, 0, 14) which doesn’t align with Sailthru’s template syntax. Sailthru uses pipe (|) for filters, and the slice filter expects the start index and length as parameters, not a generic "content" keyword.
• You’re missing the ellipsis (...) to indicate truncated content.
• Your conditions don’t handle titles that are exactly 15 characters long (they’d be omitted entirely right now).

Here’s the corrected implementation using Sailthru’s template engine:

{if length(item.title) > 15}
  {item.title|slice:0:15}...
{else}
  {item.title}
{/if}

Breakdown of the fix: #

• length(item.title) calculates the character count of the product title.
• When the title exceeds 15 characters, {item.title|slice:0:15} pulls the first 15 characters (Sailthru’s slice uses 0-based indexing, so 0:15 targets positions 0 to 14, totaling 15 characters).
• We append ... to signal the title has been truncated.
• For titles 15 characters or shorter, we display the full title without modification.

Quick tips for smooth implementation: #

• Character counts include spaces and special characters, so test with titles containing spaces or symbols to ensure truncation behaves as expected.
• Test across different email clients—most modern clients render standard ellipsis (...) correctly, but older ones might need fallback checks.
• Adjust the 15 values if you need to change the truncation limit later.
