Hey
i new to civi and actually in a setup process for a small organisation in Germany.
I have two things i would like to approach and i think hooks can do it. But i need a start to put it together.

1. I would like to add another id to a contact. This ID should be put together out of the CiviID and another ongoing number. For Exampke CiviID+0000 The best would be to have also a button to raise this id by 1. For Example to have then: CiviID+0001

2. I would like to have Checkbox at a contact dataset, which is set when the contact got a membership of a specific type.

I followed the Hooks Instruction in the Wiki, and have a functioning hook. Looks Like that:

<?php

function myhooks_civicrm_post( $op, $objectName, $objectId, &$objectRef ) {
    # configuration stuff
    $customId = 25;

    if ($objectName == 'Individual' && $op == 'create') {
        # generate the login
        $CiviID = $objectRef->id;
        $NumBer = "0001";
        $mandateRef = ($CiviID.$NumBer);

        # assign to the custom field
        $customParams = array("entityID" => $objectId,
            "custom_$customId" => $mandateRef);
        require_once 'CRM/Core/BAO/CustomValueTable.php';
        CRM_Core_BAO_CustomValueTable::setValues( $customParams );
    }
} 
Problems are now:
1. for $NumBer i would like to use the value of a custom field. How do i do that.
2. this hooks creates a second dataset of this set of custom fields. So when i look at the contact i see two time the Set in which the custom field is. And the value filled in by the hook is in the second one.
3. I want to runs this hook not only while creating accounts, but also while editing accounts.
Thanks for your help.
