Was this information Helpful?

Hi

I struggled long and hard with the uc_custom_price module, and couldn't get it to do what I wanted. I'm trying to write my own module now to achieve what I want.

I need to alter the price of a product depending on:

  1. The Attributes of the product being bought;
  2. The role of the purchaser.

My code is:

<?php

function role_price_cart_item($op, &$item) {
  switch ($op) {
  case 'load':
    global $user;
    if ('[Course Modules]' == 'All modules') {
      $code = "$item->price = '1553'";   
      }

    if (

'[Course Modules]' == 'Software module') {
      $code = "$item->price = '816'";
      }

    if (

'[Course Modules]' == 'Theory module') {
      $code = "$item->price = '628'";
      }

    if (

'[Course Modules]' == 'Professional Practice module') {
      $code = "$item->price = '298'";
      }

    if (

in_array('member', $user->roles) && '[Course Modules]' == 'All modules') {
      $code = "$item->price = '1352'";
      }

    if (

in_array('member', $user->roles) && '[Course Modules]' == 'Software module') {
      $code = "$item->price = '717'";
      }

    if (

in_array('member', $user->roles) && '[Course Modules]' == 'Theory module') {
      $code = "$item->price = '548'";
      }

    if (

in_array('member', $user->roles) && '[Course Modules]' == 'Professional Practice module') {
      $code = "$item->price = '253'";
      }

    if (

in_array('assessor', $user->roles) && '[Course Modules]' == 'All modules') {
      $code = "$item->price = '1091'";
      }

    if (

in_array('assessor', $user->roles) && '[Course Modules]' == 'Software module') {
      $code = "$item->price = '627'";
      }

    if (

in_array('assessor', $user->roles) && '[Course Modules]' == 'Theory module') {
      $code = "$item->price = '480'";
      }

    if (

in_array('assessor', $user->roles) && '[Course Modules]' == 'Professional Practice module') {
      $code = "$item->price = '0'";
      }
     
  $product = node_load($item->nid);
  $eval_code = token_replace_multiple($code, array('node' => $product, 'uc_cart_item' => $item));
  eval($eval_code);
  break;
  }
}
?>

This is having no effect at all on the price. Where is my error? Do I need to define permissions to be able to use this, or since I have none, does this automatically make it available for everyone?

Thanks

Glenn

Is never going to evaluate to true as it is simply comparing two different strings. If you want an attribute of the item, you should print_r($item) and see where that attribute exists instead of trying to use a token, which is this case is not going to work for you.

Oh, and there is no reason you need to set $code and then eval($code), just set $item->price directly.

@cYu Thanks. Where do I

@cYu

Thanks. Where do I need to put print_r($item)?

I put it in my product node, but it isn't displaying anything at all.

Thanks

Re: @cYu Thanks. Where do I

OK, found the attribute values I need.

I now have:

<?php
function role_price_cart_item($op, &$item) {
  switch ($op) {
  case 'load':
    global $user;
    if ($item->data['attributes'][1] == '1') {
      $item->price = '1553';   
      }

    if (

$item->data['attributes'][1] == '2') {
      $item->price = '816';
      }

    if (

$item->data['attributes'][1] == '3') {
      $item->price = '628';
      }

    if (

$item->data['attributes'][1] == '4') {
      $item->price = '298';
      }

    if (

in_array('member', $user->roles) && $item->data['attributes'][1] == '1') {
      $item->price = '1352';
      }

    if (

in_array('member', $user->roles) && $item->data['attributes'][1] == '2') {
      $item->price = '717';
      }

    if (

in_array('member', $user->roles) && $item->data['attributes'][1] == '3') {
      $item->price = '548';
      }

    if (

in_array('member', $user->roles) && $item->data['attributes'][1] == '4') {
      $item->price = '253';
      }
  break;
  }
}
?>

This works perfectly, but ONLY FOR THE ADMINISTRATOR!!

For any other user this has no effect at all on $item->price. This seems to indicate that it is a permissions problem. I am fast running out of time for this to be working, is anyone able to suggest where the problem is?

Thanks heaps

Glenn

UPDATE Further testing,

UPDATE

Further testing, using this code:

<?php

function role_price_perm() {
  return array('access role prices');
}

function

role_price_cart_item($op, &$item) {
  if(user_access('access role prices')) {
    echo "User has permission";
  }
  else {
      echo "No permission";
  }
}
?>

"User has permission" shows on the top of EVERY page when products are in the cart.

This message is only displayed once a user adds a product to the cart, which is what I would expect.

This message works fine, but as soon as I put in price alterations, it only works for the administrator. Is there something in the hook_cart_item to do with permissions that I don't know about??

Thanks

Glenn

I can't find it now....

It was a module which modified the display prices to show them VAT/GST inclusive.

Re: I can't find it now.... It

Thanks, I saw over in the Drupal forums it was a tax module of some sorts.

BTW ... this code is changing the price of the options inside a attribute, right?
