How to create a binding to an infoblock element? How to get SEO in the old core?

Question

1C-Bitrix

1) There are 2 information blocks questions and answers.
An answer is attached to a question through the element property (there can be several answers, so this is a multiple field)

I can attach answers to a question, but a question to an answer?
I need to implement an answer binding to a question.

2) $ipropValues ​​= new \Bitrix\Iblock\InheritedProperty\ElementValues($arParams["IBLOCK_ID"], $arFields["ID"]);
$IPROPERTY = $ipropValues->getValues();

What is the analogue on the old kernel?

The answer to your question is in the question. What are you carrying?

Answer 2

you should have at least 3 tables, not 2
1) questions
2) answer options
3) answers that link to questions and options, to the user (or who answers there)
and for the old api, see the documentation

... arSelectFields at least highloadblock

CIBlockElement --> Update --> IPROPERTY_TEMPLATES

spoiler

"IPROPERTY_TEMPLATES" => array(
"ELEMENT_META_TITLE" => $element["meta_title"], // title элемента
"ELEMENT_META_KEYWORDS" => $element["meta_keywords"], // ключевые слова элемента
"ELEMENT_META_DESCRIPTION" => $element["meta_description"], // сео-описание элемента
"ELEMENT_PAGE_TITLE" => $element["name"], // title страницы
"ELEMENT_PREVIEW_PICTURE_FILE_ALT" => $element["img"]["alt_text"], // альт для привью (маленькой) картинки
"ELEMENT_PREVIEW_PICTURE_FILE_TITLE" => $element["img"]["title_text"], // тайтл для привью (маленькой) картинки
"ELEMENT_PREVIEW_PICTURE_FILE_NAME" => $element["img"]["name"], // имя прьвью картинки
"ELEMENT_DETAIL_PICTURE_FILE_ALT" => $element["img"]["alt_text"],
"ELEMENT_DETAIL_PICTURE_FILE_TITLE" => $element["img"]["title_text"],
"ELEMENT_DETAIL_PICTURE_FILE_NAME" => $element["img"]["name"],
)

Sometimes it makes more sense to tie the other way around, in your case to the answers to questions.
What's stopping you from linking the answer to the question in the same way ?
