Typo3: How can I read the value of a field in page->edit->tab: Metadata

问题

I create a header based on one image, one Main Header and one Sub Header.

The following fields/labels in page/edit/Metadata are renamed like that:

    TCEFORM.pages.author.label.default = HeaderImageMainTitle
    TCEFORM.pages.author_email.label.default = HeaderImageSubTitle

Now I get the content of the media/create new relation/image file and that works fine. But the values of the above two fields with former label 'author' and 'author_email' stay empty (the format tags are there, but no content):

lib.headerteaser = COA
lib.headerteaser.stdWrap.wrap = <div id="headerTeaser">|</div>

lib.headerteaser.10 = IMAGE
lib.headerteaser.10 {
  file {
    import.data = levelmedia:-1, slide
    treatIdAsReference = 1
    import.listNum = 0
  }
  wrap = |
}

lib.headerteaser.20 = TEXT
lib.headerteaser.20.data = levelfield : -1 , HeaderImageMainTitle, slide
lib.headerteaser.20.wrap = <div id="headerTeaserText"><h1>|</h1>

lib.headerteaser.30 = TEXT
lib.headerteaser.30.data = levelfield : -1 , HeaderImageSubTitle, slide
lib.headerteaser.30.wrap = <p>|</p></div>

The viewhelper in the template looks like that:

    <f:cObject typoscriptObjectPath="lib.headerteaser" />

What do I miss? Studied google for hoooours!!

I tested this code, works correctly (Typo3 7.6.0).

My tested Typoscript setup (without image):

lib.headerteaser = COA
lib.headerteaser.stdWrap.wrap = <div id="headerTeaser">|</div>

lib.headerteaser.20 = TEXT
lib.headerteaser.20.data = levelfield:-1, author, slide
lib.headerteaser.20.wrap = <div id="headerTeaserText"><h1>|</h1>

lib.headerteaser.30 = TEXT
lib.headerteaser.30.data = levelfield:-1, author_email, slide
lib.headerteaser.30.wrap = <p>|</p></div>

page = PAGE
page.10 < lib.headerteaser

Setup typo3conf/LocalConfiguration.php:

<?php
return [
    ...
    'FE' => [
        'addRootLineFields' => ',author,author_email',
    ],
    ...
];

Plus clear Typo3 cache.

In .data attribute use field name, not field label:

lib.headerteaser.20.data = levelfield:-1, author, slide
lib.headerteaser.30.data = levelfield:-1, author_email, slide

And I think that You need update Typo3 configuration:

$GLOBALS['TYPO3_CONF_VARS']['FE']['addRootLineFields'] = ',author,author_email';
