Hello, can you tell how to get a description, title or filename separately inside the template? FlexicontentFields::getFieldDisplay gives already composed html string, but I need to display files list in a table-like structure so I need to get it separately.

Hello

no need to re-query DB (and waste CPU), the raw field values are already retrieved via a single SQL query and available in each item as:

$item->fieldvalues[ field_id ]

Please see our FAQ article:
Using the raw value of a field inside a template file

Yes, but for the file type field it contains what seem to be file id's:

Code:

array(1) {
  [34]=>
  array(3) {
    [0]=>
    string(2) "86"
    [1]=>
    string(2) "31"
    [2]=>
    string(2) "80"
  }
}

So my question is better rephrased as how to get file info by its id. There should be some method to access this data, except directly access _flexicontent_files table. Unfortunately have not found any info on this.

Hello

are creating the HTML of the file field ?

e.g have added field to a render-only position

if you do the above, then you can make a slight modification so that these data are available

No, I am not using template positions in this template, it's a custom template which purpose is to output selected files for download with some information about it.
I have created a separate page type and file type field with multiple values, and just need to list files on page. I have tried to use FlexicontentFields::getFieldDisplay($this->item, 'field name'), but it only gives html output as single string and array of links.
Here is how I have made it for now:

Code:

<?php if(isset($this->item->fieldvalues[$this->item->fields['resource_field']->id])){
	$files_id_list='';
	$counter=0;
	$ar_total=count($this->item->fieldvalues[$this->item->fields['resource_field']->id]);
	foreach($this->item->fieldvalues[$this->item->fields['resource_field']->id] as $file_id){
		$files_id_list.='\''.$file_id.'\'';
		if($counter !== $ar_total - 1){$files_id_list.=',';}
		$counter++;
	}
	$db = JFactory::getDbo();
	$query = $db->getQuery(true);
	$query->select(array('id','filename', 'altname', 'description', 'access', 'ext'));
	$query->from('#__flexicontent_files');
	$query->where('id IN('.$files_id_list.')');
	$query->order('id ASC');
	$db->setQuery($query);
	$files_info = $db->loadObjectList();
	foreach($files_info as $file){
		$file->link='/'.$this->item->alias.'/download/'.$file->id.'/'.$this->item->id.'/'.$this->item->fields['resource_field']->id;
	}
	foreach($files_info as $file){
		if($file->access==1){
			 ?>
			<div class="resource_field">
				<img class="file_icon" src="<?php echo $templateDir; ?>/img/<?php echo $file->ext; ?>.png"/>
				[url=<?php echo $file->link?>" class="file_link]<?php echo $file->altname?>[/url]
				<p class="file_desc"><?php echo $file->description; ?></p>
			</div>
	<?php }
	}

I am receiving all information I need about files and display it in custom format. I just thinking about how can I improve it so I can receive that data by flexicontent methods, maybe there is some additional arguments to getFieldDisplay function?

Hello

ok just you are executin 1 query per item, this is very fast, because files table is small and you are query via IDs !!

but if you display more than 100 items in category it maybe better to create only 1 query for ALL items
