if you need access other fields in your field template, you can access them by
<?
echo $row->{$view->field[‘FIELD_ID’]->field_alias};
?>
You will be able to add some logic to your template like
<?
if($row->{$view->field[field_B_value]->field_alias})
{
echo $outputĀ ;
}
else
{
echo “B is not available”;
}
?>
Note the ‘FIELD_ID’ can be something different depending on the field type. it can be “field_B_nid” (if it is node reference), or “field_B_value” if it is a regular text field, or “field_B_rating” (if a five star rating field). You can check all of your FIELD_ID by the following code
<?
foreach($view->field as $k=>$f){
echo $k;
}
exit;
?>
put the above code to your template file and view your view’s page url, you will see the output of the FIELD_ID of your fields.
the advantage of doing this instead of using directly $row->FIELD_ALIAS_NAME, is you don’t need update your views theme each time you update your view (for example, adding a new field), because the FIELD_ALIAS_NAME can change when fields are changed or reordered.
