How to display the default value of a property?

Question

1C-Bitrix

A component with a feedback form has been developed (receives the data left by the user in the inputs and enters them into the info block). I display on the page through bitrix:news.list. You need to add a new property with a binding to the user. In this case, if VALUEthe property is empty, you need to display "Application is open". However, the logic of the component is such that if VALUEthe property is empty, then DISPLAY_PROPERTIESit does not fall into it. I think the most correct approach is:

• Create a property of type "String";
  
• Set <input type="hidden">from namethis property and value="Заявка открыта", and thus add an element to DISPLAY_PROPERTIES;
  
• Then display it on the page and add the ability to change the value of the property using CIBlockElement::Updatethe user ID;
  

How to display the default value of a property?

Answer 1

I borrowed this approach from the component controller. In case the DEFAULT_VALUE property is filled, it also contributes to DISPLAY_PROPERTIES.

foreach($arResult["ITEMS"] as &$arItem)
{
    foreach($arParams["PROPERTY_CODE"] as &$pid)
    {
        $prop = $arItem["PROPERTIES"][$pid];
        if(
            (is_array($prop["DEFAULT_VALUE"]) && count($prop["DEFAULT_VALUE"])>0)
            || (!is_array($prop["DEFAULT_VALUE"]) && strlen($prop["DEFAULT_VALUE"])>0)
        )
        {
            $arItem["DISPLAY_PROPERTIES"][$pid] = CIBlockFormatProperties::GetDisplayValue($arItem, $prop, "news_out");
        }
    }
}
unset($arItem, $pid);
