I have a body function and a function called within the first one.
As can be seen below I don't change the parameters name while using in the second function.
Is it necessary to change the params names for use inside _display_bar();? What are the side effects if I don't?
function main_func($form, &$form_state, $key, $code) {
$output = '';
...
$output .= _display_navbar($trans, $status_names);
return $output
}
function _display_navbar($trans, $status_names) {
$trans = 'bla';
$status_names = 'another bla';
$bar = $trans . ':' .$status_names;
return $bar;
};
