Introduction

If you're working with Magento 2.3.6 and are facing the error message:

then you're not alone. This issue tends to arise when trying to add a configurable product to the cart after selecting a delivery time, particularly on store views set for right-to-left languages like Arabic. The root of the problem often lies in how dates are formatted—and understanding how PHP's DateTime class interprets these formats can save you a lot of headaches.

In this guide, we will explore why this error occurs and how to effectively resolve it by modifying the way dates are processed in your Magento application.

Understanding the Problem

The issue arises from the following code snippet:

When DateTime tries to create an instance using a date format like 25/02/2022 (which is common in European formats), it fails because DateTime expects the format to be Y-m-d (like 2022-02-25). As a result, Magento throws a critical error, preventing the addition of items to the cart.

Key Takeaways:

The error occurs due to incompatible date format for the DateTime constructor.

This is particularly evident when using European date formats in a Magento store configured for right-to-left languages.

The Solution

Fortunately, there's a simple workaround that can resolve this issue. By replacing the slashes in the date format with dashes, DateTime can parse the string correctly. Here’s how you can implement this fix:

How to Fix the Error

Locate the Code: Start by identifying where the error occurs in your Magento code:

Modify the Date Format: Adjust the line of code where the DateTime object is instantiated. Use the str_replace function to replace slashes with dashes:

Test Your Changes: After making this change, ensure that you test the functionality by selecting a delivery time and attempting to add the configurable product to the cart again.

Final Thoughts

By converting the date format from European style (e.g., 25/02/2022) to an acceptable format for DateTime in PHP (e.g., 2022-02-25), you avoid the critical error and improve the functionality of your Magento store.

This simple adjustment not only resolves the immediate issue but also enhances your code’s robustness with date handling.
