change product price in cart

This function is easily found and it also does what it should as long as the custom_price is hardcoded.

Wouldn’t that mean the issue is in your CSV handling code, not the above snippet?

Maybe. But how would you handle the dynamical price? If I change that function to something like:

function add_custom_price( $cart_object, $price) {
  $custom_price = $price; // This will be your custome price
  foreach ( $cart_object->cart_contents as $key => $value ) {
    $value['data']->price = $custom_price;
  }
}

It errors out on missing parameters even though I send them.

You cannot ‘send’ a price via that function/hook. Your price logic needs to be inside the function.

Any idea then to how i could somehow get to access that new price value inside the function? That’s the problem to begin with. I could do all shorts of logic but as long I can’t access the new/edited value the output will never be what it should anyway.

You’d call whatever price parsing/csv code you have there. I cannot help you with that part – I don’t know what else you’re doing to get prices.

Ok then. I’m kind of stuck on my own so let’s take the relevant code here step by step.

In my price.php template file:

global $product;
do_action('show_price', $product);?>

In my functions.php:

add_action( 'show_price', 'show_price_function');

function show_price_function($product) {
  if ($product->is_type( 'simple')) {
    if ($product->get_sku()) {
      $file_handle = fopen("filename", "r");

      while (!feof($file_handle) ) {
        $line_of_text = fgets($file_handle);
        $parts = explode(';', $line_of_text);
        $var = $product->get_sku();

        if ($parts[0] == $var) {
          $extra = 5;
          $answer = round((($extra / 100) * $parts[2]) + $parts[2], 0);
          $product->set_price($answer);
        };
      };
      fclose($file_handle);
    };

    $incl = $product->get_price_including_tax();
    $excl = $product->get_price_excluding_tax();

    //warning deprecated functions-->?>
    <p class="price"><?php echo woocommerce_price($excl);?> excl. tax</p>
    <p class="price" style="display:none;"><?php echo woocommerce_price($incl);?> incl. tax</p>
    <button class="tax">Se price incl. tax</button>

Also in my functions.php

add_action( 'woocommerce_before_calculate_totals', 'add_custom_price' );

function add_custom_price( $cart_object) {
  $custom_price = 1256 // This will be your custome price
  foreach ( $cart_object->cart_contents as $key => $value ) {
    $value['data']->price = $custom_price;
  }
}

So the price that I display in the two paragraphs are the new ones.
What I at first thought happened with the set_price function was that the price for that product was changed throughout the site which it doesn’t though. But that’s the value I would like to be able to somehow access inside the custom price function. Any help in direction greatly appreciated!

The logic which parses the file and gets a price should be moved to a separate plugin, then you can use it in both ‘show_price’ and ‘add_custom_price’.

Really though, this could be optimised further. Consider getting a developer to customise this for you, jobs.wordpress.net

Hi,

In the late version of woocommerce $value[‘data’]->price = $custom_price; this code is not updating the price in cart.

Can you please send me the late code to update price of product in cart programmatically?

Thanks
