Often times, you may want to customize the appearance of a views field, or perhaps add a bit of logic to the output. You can customize the display of any field in Views by utilizing the Views Customfield module.

Here's an example of how to breakdown a basic cck fieldfield into its constituent parts.

//print var_export($data, TRUE); //prints out all available fields in view

$value = $data->node_data_field_document_field_document_fid; //relevant fid

if ($value != NULL){

$file = field_file_load($value);
//print_r($file); //prints out various rows for file array
$filepath = base_path().$file['filepath'];
$filename = $file['filename'];
$icon = theme('filefield_icon', $file);
$filesize = format_size($file['filesize']);
$link = "$filename";

//print "

";
print $icon;
}
?>

For filefields with multiple values, you can use this model:

//print var_export($data, TRUE); //used to find all available variables in views $data array

foreach ($data->node_data_field_rfp_exhibits_field_rfp_exhibits_fid as $key => $value){

if ($value['fid'] != NULL){
//print_r($file); //used to find all available variables in filefield array
$file = field_file_load($value['fid']);
$filepath = base_path().$file['filepath'];
$filename = $file['filename'];
$icon = theme('filefield_icon', $file);
$filesize = format_size($file['filesize']);
$link = "$filename";

echo "

";

}
}

?>

Don't forget to use var_export() in order to find the correct name of your filefield variable. Then replace "$data->node_data_field_document_field_document_fid" with your variable.
