Join two fields - member registration

[wotanskrieg]

Hi,
I've add custom fields to member registration.
1. Phone Operator (select)

Now I've made one more custom field where I would like to join Phone operator and Phone number when the form is submitted. Results would be: In database the Phone Operator and Phone Number should be in that new table field.

How could be this accomplished?

Thanks for any help!

You could use the createNewUser hook, which triggers on registration.

The hook needs to be registered in a config file

$GLOBALS['TL_HOOKS']['createNewUser'][] = array('ClassName', 'functionName');

and the Class added somewhere - so you might need to make a little module to do this.

ClassName.php

<?php if (!defined('TL_ROOT')) die('You can not access this file directly!');

class ClassName extends Backend
{  

    public function functionName($intId, $arrData)
   {
        $operatorAndPhone = $arrData['operator'] .'-'. $arrData['phone'];	
       $this->Database->prepare("UPDATE tl_member SET newfieldName=? WHERE id=?")
       ->limit(1)
       ->execute($operatorAndPhone,$intId);		
   }

}

?>
