This api exists so that other modules can easy set the values of the field without having the need to change the render method as well.

Parameters

string $field: Optional name of the field where the value is stored.

Overrides views_handler_field_field::get_value

Class

commerce_price_handler_field_commerce_price

An extension of the default Views field handler that supports aggregating price fields.

Code

function get_value($values, $field = NULL) {

  // If this field has aggregation enabled...
  if (!empty($this->group_fields)) {

    // Loop over the aggregated database fields looking for aggregation on the
    // price field's amount column.
    foreach ($this->group_fields as $field_name => $column) {

      // If we find it, whether currency_code aggregation is enabled or not,
      // we simulate it / override it and provide a default value in the
      // $values array that uses the currency code of the representative
      // entity used in parent::get_value() or the site's default currency.
      if ($field_name == 'amount') {

        // Generate a pseudo column name that will not have a collision,
        // because it's based on extending a column name that will never
        // otherwise have _currency_code appended to it. Note that this means
        // you cannot use aggregation on multi-currency price fields or
        // outside of an entity context where field values may use a currency
        // other than the site's default currency.
        $pseudo_column = $column . '_currency_code';
        $this->group_fields['currency_code'] = $pseudo_column;
        $this->aliases[$pseudo_column] = $pseudo_column;

        // Extract the entity from the values array.
        $entity = $values->_field_data[$this->field_alias]['entity'];
        $entity_type = $values->_field_data[$this->field_alias]['entity_type'];
        $langcode = $this
          ->field_language($entity_type, $entity);

        // And finally put a valid currency code in the pseudo column value.
        $currency_code = NULL;
        if (!empty($entity->{$this->definition['field_name']}[$langcode])) {
          $items = $entity->{$this->definition['field_name']}[$langcode];
          $delta = key($items);
          if (!empty($items[$delta]['currency_code'])) {
            $currency_code = $items[$delta]['currency_code'];
          }
        }
        if (empty($currency_code)) {
          $values->{$pseudo_column} = commerce_default_currency();
        }
        else {
          $values->{$pseudo_column} = $currency_code;
        }
      }
