PHP Fatal error: Uncaught TypeError: Unsupported operand types: string + string

Resolved

(@diegosn79)

When we place an order with a credit card that adds a fee, this error occurs, and wc fails to display the order placed page. Although the order is paid and carried out correctly.

It just shows an error, “An error occurred, try again.”

This error is very similar to this solved issue:

I found the solution so that it doesn’t throw the error anymore and everything works correctly. It would be ideal if some wc expert could confirm this:

The “PHP Fatal error: Uncaught TypeError: Unsupported operand types: string + string” error occurs when trying to add two values of type string instead of adding two numbers. In the line where the value of “value” is set, the wc_price function returns a string representing a formatted price, and tries to add that value with another string ($fee->get_total_tax()) to calculate the price including tax .

To fix the error, both values must be converted to numbers before adding them, for example, using floatval in file abstract-wc-order.php lines 2195-2197:

$total_rows[ ‘fee_’ . $fee->get_id() ] = array(
‘label’ => $fee->get_name() . ‘:’,
‘value’ => wc_price( ‘excl’ === $tax_display ? floatval( $fee->get_total() ) : floatval( $fee->get_total() ) + floatval( $fee->get_total_tax() ), array ( ‘currency’ => $this->get_currency() ) ),);

Hello,

Glad to know you have found a work-around.

Unsupported operand types: string + string” error occurs when trying to add two values of type string instead of adding two numbers. In the line where the value of “value” is set, the wc_price function returns a string representing a formatted price, and tries to add that value with another string ($fee->get_total_tax()) to calculate the price including tax .

You might be right.

To clarify, is the issue still present if you disable all plugins except WooCommerce and switch the site theme to Storefront?

Let us know what you find.

Hello Igor, the problem appears when using the credit card payment method managed by the NPS Ingenico plugin
https://github.com/Ingenico-NPS-Latam/nps-plugin-woocommerce

This plugin is not maintained by technical support.

I think the problem is generated when the plugin delivers the tax or installment applied with this format number that we use in Argentine $1,000.00.

Hi @diegosn79

Thanks for sharing further information about your issue here.

Since the problem appears when using the third-party plugin NPS Ingenico plugin, I’m afraid that it would be best to reach out to the developers since this is outside our scope of support (please see our Support Policy).

However, as you’ve mentioned that the plugin is not being maintained, you could check the links below if it helps.

For questions related to development and custom coding, your best bet is to ask on any of these channels for support. We’re lucky to have a great community of open-source developers for WooCommerce, and many of our developers hang out there, too.
Hope this helps!
