Hi,

I'm using buildmaount hook for event to give membership discount. I'm getting the email address using jquery and checking membership by passing the email id in url and using $_GET method retrieving email. Then using Api to check membership of the email id.
Its working in the register page. it gives the discounted amount. But when i go to the Confirm page it gives Original amount and not the discounted amount.

Any idea.

I have been trying for hours to get the buildAmount hook to change the values on a price set for an event registration, but nothing I do makes any difference.

I can update the ['amount'] element and have the changed value displayed in a watchdog message, but there is no change to the value displayed when the event registration page is loaded.

I am also calling the buildForm hook. Could this be overwriting changes?

Can you tell me how you are checking the form in buildAmount hook

Bump - any luck, anyone?  I'm having the same problem after installing my Drupal module on a new 4.2.2 - Drupal 6 installation.  Worked in 4.1 and Drupal 6.

Update: Yes, it's changed.  Here's the output of print_r($amount) in hook buildAmount:

Array
(
    [2] => Array
        (
            [id] => 2
            [name] => Event Fee(s)
            [label] => Event Fee(s)
            [html_type] => Radio
            [is_enter_qty] => 0
            [weight] => 1
            [is_display_amounts] => 1
            [options_per_line] => 1
            [is_active] => 1
            [visibility] => public
            [visibility_id] => 1
            [is_required] => 1
            [options] => Array
                (
                    [2] => Array
                        (
                            [id] => 2
                            [price_field_id] => 2
                            [name] => Dummy_fee
                            [label] => Dummy fee
                            [amount] => 10
                            [weight] => 1
                            [is_default] => 1
                            [is_active] => 1
                        )

                )

        )

    // And here's what my code did, as per the 4.0 hook specification,
    // which used to work but doesn't anymore:
    [100] => Array
        (
            [value] => 375
            [label] => Current fee
            [amount_id] => 100
        )

)

Another update:  I got past the initial hurdle by putting my information into the ['options'] array above with appropriate changes (amount_id changed to id) and unsetting the existing element.  However, CiviCRM code changes have made this orders of magnitude more complicated:

 - All prices are parts of price sets.
 - I got the buildAmount to work, but then upon confirming the registration, it gives a cannot-go-any-further error.  A look at the log reveals foreign key constraint issues involving civicrm_line_item and price_field_value_id.  Basically I'm making up an option in a price set that doesn't exist.
 - It seems the registration was created anyway.  Code I wrote to modify the Edit participant screen to allow an admin editing the fee works too, except it leaves the Fee Level displaying as "Array" rather than what it's supposed to be ("Current fee").

My module calculates a fee based on a form on a per-participant basis.  The fee can be different for every participant - yet the dummy fee I created sits with a price of $10 in civicrm_price_field_value.  This wasn't a problem in Civi 4.1, which didn't use price sets for simple fees - I could just override the fee option and be done with it.  Any recommendations on what to do with this?

Thank you, dlobo!  I had success substituting the following code for what I had in Civi 4.1:

foreach($amounts as &$fee) { // There's only one
  foreach($fee['options'] as &$option) { // There's only one
    $option['amount'] = $value;
    $option['label'] = $label;
    $option['name'] = $name;
    $option['id_default'] = 1;
  }
}

Now here's another question:  I also wrote some code for the Participant edit screen which allows an admin to edit the Participant record's fee_amount entry.  I know the display gets funny, but do I really need to edit the associated line_items too?  If not, the display from the line item could just be considered the "originally calculated" fee.
