问题
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:
PHP Notice: Undefined index: model in /home/xxx/public_html/admin/controller/catalog/product.php on line 651

回答1:
The following are some possibilities:
The fields (listed in your errors) don't exist in your database.
There might be some problem with your product_form.tpl template file.
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.

These simply occur when $product_info['variable mentioned in error is not specified'], a simple, and complete fix is to edit the query like below:
elseif (isset($product_info)) {
$this->data['location'] = $product_info['location'];
}
Into:
elseif (isset($product_info['location'])) {
$this->data['location'] = $product_info['location'];
}
And do so for each of the cases, furthermore you can do this for all $product_info[] data to avoid future errors like that.

In case of when just some of the indexes undefined, the reason for it may be very simple: if the properties are not set in the admin panel (like in my case for Length, Weight and in stock).
