Since we were converting the field to lowercase we ended up inserting meta in all lowercase, regardless of what it was in the CSV file. We should only be using the normalized field name when looking at the default columns, and should instead rely on a case-insensitive regex for the special columns.
One thing to note is that we're still defaulting the $headers array to the normalized field, as we don't want to change what is being passed to the filter for unmapped columns.
WordPress Coding Standard 2.0 removed the sniff
WordPress.Security.NonceVerification.NoNonceVerification:
```
The WordPress.Security.NonceVerification sniff used the same error code for both an error as well as a warning.
The old error code NoNonceVerification is no longer used.
The error now uses the Missing error code, while the warning now uses the Recommended error code.
```
(from
d45f5e5cf3/CHANGELOG.md (200-rc1---2018-12-31))
This commit updates WooCommerce code and replaces all instances where WordPress.Security.NonceVerification.NoNonceVerification verification was used with either WordPress.Security.NonceVerification.Missing or
WordPress.Security.NonceVerification.Recommended. In a few cases WordPress.Security.NonceVerification.NoNonceVerification was used but was not needed, so instead of replacing the sniff, the line was removed. In two other cases, I removed other unrelated sniffs that were not needed.
The name of one of the WPCS sniffs changed from WordPress.CSRF.NonceVerification.NoNonceVerification to WordPress.Security.NonceVerification.NoNonceVerification. This commit updates all instances where this sniff is used in WooCommerce codebase.
Fixed notice:
```
PHP Notice: Only variables should be passed by reference in includes/admin/importers/class-wc-product-csv-importer-controller.php on line 298
```
When the file is empty or using an incorrect charset will display just an empty screen, since we output errors before check if the file is valid.
I included the error output inside the mapping step in order to fix this issue, and added a new option to display buttons after the error message.
Closes#16928
* Introduce woocommerce_product_csv_importer_args filter.
* Add extra args to WC_Product_CSV_Importer. Have fgetcsv use extra args
* Update to follow coding standards.
