Change code to account for multiple values in field

[calebm12]

I am using the following code to amend a value entered in a field prior to inserting in a database.  i am wondering how to change it so that if the field has multiple values (separted with comma or space) it will amend each value and not just the last one.

function citizenspeak_nodeapi(&$node, $op) {
  switch ($op) {
    case 'presave':
        $node->email_recipients = $node->email_recipients.'@metrofax.com';
  }
}

explode will change a string to an array, then use foreach.

Sorry for my ignorance.  very green.  not sure how to mix that into the code

 

$pieces = explode(" ", $node->email_recipients);

foreach ($pieces as $node->email_recipients);

function citizenspeak_nodeapi(&$node, $op) {

  switch ($op) {

    case 'presave':

        $node->email_recipients = $node->email_recipients.'@metrofax.com';

  }

}

Define your function outside the foreach loop.
