Opencart Undefined index Errors in product

Question

I am using OpenCart 1.4.9 and I have been dealing with Undefined index Errors in product.php recently, I suspect it happens every time the user is creating/input a new product on the dashboard.

How to fix these errors because it makes the server resource overload, my site resource usage peaked at 91% sometimes 100% on the cPanel?

Here is the model file.

Here is the controller file.

Here are the errors I am getting:

Answer 1

The following are some possibilities:

1. The fields (listed in your errors) don't exist in your database.

2. There might be some problem with your product_form.tpl template file.

3. Check whether the values are getting inserted correctly to the product tables while adding a product.

Comparing the admin product files with a fresh unedited OpenCart 1.4.9 admin product files will help you to find out the issue.
