Round Commerce Price: in tpl.php or template.php

Question

Currently I'm using Commerce and Commerce Multicurrency to our currency in Indonesia.

Sometimes there is a price to numbers that are not rounded.

With print render ($ content ['product: commerce_price']) I get the original price.

I've tried to edit the tpl.php file and the results are as desired.

number_format (round ($ price, -4), 0);

2,511,000 into 2,500,000 2,565,000 into 2,600,000

But after some reading and hopefully not misread. That is not good in tpl.php, but should be in template.php or modules.

Please advise to help me.

A better way to adjust currency formatting, using the relevant Commerce currency hooks, is with

hook_commerce_currency_info_alter

and adding your own commerce_currency_format handler

e.g:

/**
 * hook_commerce_currency_info_alter
 * 
 * Add custom currency format to selected currencies
 */
function MY_MODULE_commerce_currency_info_alter(&$currencies){
  $currencies['IDR']['format_callback'] = 'MY_MODULE_commerce_currency_format';
}

/**
 * Currency format callback
 *
 * Remove decimal places from output
 * while keeping commerce_amount_to_decimal formatting the same
 *
 * See: commerce_currency_format
 */
function MY_MODULE_commerce_currency_format($amount, $currency, $object = NULL, $convert = TRUE) {

  // Format the price as a number.
  // In our case, we remove decimal places
  $price = number_format(commerce_currency_round(abs($amount), $currency), 0, $currency['decimal_separator'], $currency['thousands_separator']);

  // Establish the replacement values to format this price for its currency.
  $replacements = array(
    '@code_before' => $currency['code_placement'] == 'before' ? $currency['code'] : '',
    '@symbol_before' => $currency['symbol_placement'] == 'before' ? $currency['symbol'] : '',
    '@price' => $price,
    '@symbol_after' => $currency['symbol_placement'] == 'after' ? $currency['symbol'] : '',
    '@code_after' => $currency['code_placement'] == 'after' ? $currency['code'] : '',
    '@negative' => $amount < 0 ? '-' : '',
    '@symbol_spacer' => $currency['symbol_spacer'],
    '@code_spacer' => $currency['code_spacer'],
  );

  return trim(t('@code_before@code_spacer@negative@symbol_before@price@symbol_spacer@symbol_after@code_spacer@code_after', $replacements));
}

As per your comment you have done it by making some module. But still I will tell you my way to doing it.

As you want to print the value after rounding it in your node.tpl.php, you can go for implementing THEME_preprocess_node(&$variables) function in your template.php file of the theme which you are using. Replace THEME with your theme name in there.

Now implement something like this,

function indiareads_preprocess_node(&$vars){
  if ($node = menu_get_object()){
    if($node->type == 'YOUR_PRODUCT_DISPLAY_TYPE'){
      $product_id = $node->FIELD_PRODUCT_REFERENCE['und'][0]['product_id'];
      $product = commerce_product_load($product_id);
      $price = $product->commerce_price['und'][0]['amount'];
      $rounded_price = number_format(round($price,-4), 0);
      $vars['rounded_price'] = $rounded_price;
    }
  }
}

Replace YOUR_PRODUCT_DISPLAY_TYPE with the name of content type which is displaying your product & FIELD_PRODUCT_REFERENCE with the name of field of that content type which reference the commerce product.

After this when you will go to node.tpl.php, you will have $rounded_price variable available to print where ever you want.

I am writing this for better understanding of the system even if you have done that, so that if somebody comes searching can get help.
