TypoScript / Typo3: How to build sub-content of a page using header_link value? - typo3

Question

How can I build a sub-content (nested content) of a page using typoscript with reference to the parent's header_link field?
Desired output is something like:
<h1>Title of parent</h1>
<p class="prt">Body of parent</p>
<h3>Title of Child</h3>
<p class="cld">Contents of child</p>
Sample of my Typoscript:
temp.myParentVal = CONTENT
temp.myParentVal {
table = tt_content
select {
begin = 1
orderBy = sorting
where = (colPos = 1)
}
renderObj = COA
renderObj {
10 = TEXT
10 {
required = 1
wrap = <h1> | </h1>
stdWrap.field = header
}
20 = TEXT
20 {
required = 1
wrap = <p class="prt"> | </p>
stdWrap.field = bodytext
}
# #
# WHAT SHOULD I DO HERE TO SHOW THE CHILD CONTENT OF THIS PAGE #
# (REFERENCED BY header_link FIELD IN THE PARENT'S ROW), #
# WHICH HAS THE FORMAT OF <child_pid#child_uid>, EG.'11#28' #
# #
stdWrap.wrap = <div> | </div>
}
I would like to make use of parent's header_link field value to generate the content for the child. (I'm using TYPO3 v. 6.2.14)

You can use a nested CONTENT element and split the header_link via Regex like this:
30 = CONTENT
30 {
table = tt_content
select {
uidInList {
field = header_link
stdWrap.replacement.10 {
search = /^.+#/
replace =
useRegExp = 1
}
}
pidInList {
field = header_link
stdWrap.replacement.10 {
search = /#.+$/
replace =
useRegExp = 1
}
}
}
renderObj = COA
renderObj {
10 = TEXT
10.value {
required = 1
wrap = <h3> | </h3>
field = header
}
20 = TEXT
20.value {
required = 1
wrap = <p class="cld"> | </p>
field = bodytext
}
}
}
Also, I wanted to suggest that you use the field property directly on the TEXT elements (which works). But I looked it up in the docs:
stdWrap properties are available on the very rootlevel of the object. This is non-standard! You should use these stdWrap properties consistently to those of the other cObjects by accessing them through the property "stdWrap".
https://docs.typo3.org/typo3cms/TyposcriptReference/ContentObjects/Text/Index.html
As value is a stdWrap object, you could use it as I did above.
