Understanding the Problem with Conditional Statements in Prestashop TPL Files

If you've ever tried to implement conditional logic in your Prestashop templates, you may have run into some challenges—especially when working with the order confirmation page. Recently, a user posed a question about displaying conditional vouchers based on two specific conditions:

The weight of the order.

Whether the user has an account.

The user was working with the file /public_html/themes/mytheme/templates/checkout/order-confirmation.tpl and had drafted a code snippet that wasn't producing the desired results. Here's a brief look at the user's original attempt:

While the good news was that the page was functioning without crashing, the bad news was that nothing displayed even when the conditions were fulfilled. So, what was missing?

The Solution: Adjusting Your Conditional Logic

Correcting the User Account Condition

The primary issue was the use of the variable $logged, which is not available in Prestashop 1.7. Instead, you should use $customer.is_logged to evaluate whether the customer has an account. Here’s how to modify your original code for it to work effectively:

Breakdown of the Changes Made

Replacement of the $logged Variable:

Before: $logged

After: $customer.is_logged

This change is critical as it aligns with the current conventions in Prestashop 1.7, ensuring that you are referencing the correct variable to check if the user is logged in.

Structural Integrity: Ensure that the conditions are logically linked properly using the && operator, which means both conditions must be true for the corresponding voucher to display.

Testing the Changes

After you implement the changes, simulate a checkout scenario that meets the conditions you've set up (i.e., order weight equals or exceeds 1.00 or 2.00, and the user is logged in). Verify that the correct voucher is displayed accordingly.

Final Thoughts

By simply updating the code to use $customer.is_logged, you should now be able to display conditional vouchers based on the order's weight and account status successfully. This minor adjustment can make a significant difference, improving user experience and enhancing your Prestashop store's performance.

If you continue to experience issues after making these updates, double-check the logic and variable names, and don’t hesitate to seek further assistance from the community or documentation.

Remember, coding challenges are common, and with persistence, you can solve them effectively!
