PHP - How do I combine both of these functions

swingking

I have 2 separate disclaimers but they are using the same code.

The problem is they won't work together.

How can I combine both of these functions into a single working function

function decawave_preprocess_field(&$vars) {
if($vars == "field_resource_public_pdf" || $vars == "field_resource_pdf") {
$vars[0] = !empty($vars->field_disclaimer) ? $vars->field_disclaimer[LANGUAGE_NONE][0] : 0;}
}

function decawave_preprocess_field2(&$vars) {
if($vars == "field_resource_public_pdf" || $vars == "field_resource_pdf") {
$vars[0] = !empty($vars->field_antenna_disclaimer) ? $vars->field_antenna_disclaimer[LANGUAGE_NONE][0] : 0;
}
}

From what I can see the only difference is the method call to either field_disclaimer or field_antenna_disclaimer, so why not call a single method twice and pass the name of the method to call with it
Something like below?

 function decawave_preprocess_field(&$vars, $mName) {
                if($vars['element']['#field_name'] == "field_resource_public_pdf" || $vars['element']['#field_name'] == "field_resource_pdf") {
                    $vars['items'][0]['#disclaimer'] = !empty($vars['element']['#object']->$mName) ? $vars['element']['#object']->$mName[LANGUAGE_NONE][0]['value'] : 0;
                }
            }

edit: a more efficent way is to combine them in a single function, if you are always calling it from the same place

function decawave_preprocess_field(&$vars) {
                if($vars['element']['#field_name'] == "field_resource_public_pdf" || $vars['element']['#field_name'] == "field_resource_pdf") {
                    $vars['items'][0]['#disclaimer'] = !empty($vars['element']['#object']->field_disclaimer) ? $vars['element']['#object']->field_disclaimer[LANGUAGE_NONE][0]['value'] : 0;
                    $vars['items'][0]['#disclaimer'] = !empty($vars['element']['#object']->field_antenna_disclaimer) ? $vars['element']['#object']->field_antenna_disclaimer[LANGUAGE_NONE][0]['value'] : 0;
                }
            }

Yes I have tried that but it's not allowing the disclaimer file to be displayed directly.

Only when you have the first function operating and not the second one

Thanks
