How to display infoblock property in bitrix:catalog.section.list template?

Question

1C-Bitrix

Something I shoveled everything, I just can not figure out how to implement it.
Created a new property (file type) for the elements in the infoblock:



I go to the element, I see that the property is active, I upload the file:



Then I include it in the Component Parameters:



after that I go to the template, check the arResult variable and see that the property did not start there :

Help me figure out how to add a property to the arResult array, through result_modifier.php
And how to display this thing in a template

Answer 1

In general, thank you all. As a result, done through the properties of the element.
Added to the template file:

$LINK = (!empty($arElement["DOCUMENTS"]) ? $arElement["DOCUMENTS"] : $arElement["PREVIEW_PICTURE"]);
        $DOWNLOAD_ATTRIBUTE = (!empty($arElement["DOCUMENTS"]) ? 'download="'.$arElement["NAME"].'"' : '');


<a href="<?=$LINK;?>" <?=$DOWNLOAD_ATTRIBUTE;?> class="fancybox" title="<?=$arElement["PREVIEW_TEXT"];?>" rel="document">

in result_modifier:

if(in_array("DOCUMENTS", $arSelect))
      $arItem["DOCUMENTS"] = CFile::GetPath($arItem["PROPERTY_DOCUMENTS_VALUE"]);

Answer 2

you added a property of the infoblock element and want to get it in the section? stupid)

Answer 3

You use the "list of sections" component, where, accordingly, the sections of the infoblock are displayed.
Accordingly, either the property must be set for the section, or you will have to act in two stages:
In the result_modifier for each output section, get a list of elements (with properties, respectively). In this case, what you're displaying already has elements, but they don't have properties. It is necessary to add all the IDs of the elements into an array and call GetList with a filter by ID and a selection of the desired property
In the template, display elements with properties for each section
But! It seems to me that the component is incorrectly selected here, use bitrix:catalog.section for the root section. There in the parameters specify the desired property
