TYPO3中如何通过TypoScript正确添加作者邮箱至meta标签

Since HTML5 allows the author meta tag to include both name and email in the format name, email@example.com, you can use a Content Object Array (COA) in TypoScript to merge the author name and email values from your page fields. Here's how to modify your existing code:

page = PAGE
page {
    meta {
        author = COA
        author {
            # Get the author name (using your existing slide/override logic)
            10 = TEXT
            10 {
                data = levelfield :-1, author slide
                override.field = author
            }
            
            # Add comma + space only if both name and email exist
            20 = TEXT
            20 {
                value = , 
                stdWrap.if.isTrue.field = author_email
                stdWrap.if.isTrue.data = levelfield :-1, author_email slide
            }
            
            # Get the author email (mirroring the name's slide/override logic)
            30 = TEXT
            30 {
                data = levelfield :-1, author_email slide
                override.field = author_email
            }
        }
    }
}

Key Details: #

• COA (10-30): This content object array lets us build the final meta content string step by step.
• Author Name (10): Reuses your existing logic to pull the author name—either from the current page or sliding up to parent pages if it's not set on the current page.
• Separator (20): Adds a comma and space only if an author email exists (either on the current page or a parent page). This prevents unwanted trailing commas when there's no email.
• Author Email (30): Mirrors the name's sliding/override logic to retrieve the email address consistently.

Edge Cases Handled: #

• If only the author name exists: The meta tag will display just the name (no extra punctuation).
• If only the author email exists: The meta tag will show just the email (though pairing it with a name is recommended, this handles the scenario gracefully).
• If both name and email exist: They'll be combined in the valid HTML5 format (name, email@example.com).
