Let me see if I understand your issue. You are saying that when you create a new product and you don’t enable **_Use variations only to construct final product price_** you see the error you mention above. Is this correct? * Kind regards. * Thread Starter [enomoto celtislab](https://wordpress.org/support/users/enomoto-celtislab/) * (@enomoto-celtislab) * [2 years, 3 months ago](https://wordpress.org/support/topic/php-error-handle-variations/#post-17411967) * yes I don’t use variations when saving products. However, PHP program processing determines that it is being used. This will do the wrong thing and cause a PHP error * Plugin Support [mbrsolution](https://wordpress.org/support/users/mbrsolution/) * (@mbrsolution) * [2 years, 3 months ago](https://wordpress.org/support/topic/php-error-handle-variations/#post-17413935) * Thank you for sharing more information.

Can you check to see if this version fixes your issue. * Thank you. * Thread Starter [enomoto celtislab](https://wordpress.org/support/users/enomoto-celtislab/) * (@enomoto-celtislab) * [2 years, 2 months ago](https://wordpress.org/support/topic/php-error-handle-variations/#post-17543934) * The error can no longer be reproduce. * My guess is that when the error occurred, asp_variations_names was undefined, so filter_input () became null. After that, when I corrected the code and executed it to check the operation, update_post_meta( $post_id, ‘asp_variations_names’, false ); was executed, the undefined was resolved, and the error no longer occurred. * However, if you click the Create Group button in variations and update the Edit Product without creating a variation, an empty variation will be created. * When you Pay Now for this item, an empty dropdown select for variation selection will appear at the top of the purchase dialog. * Is this the expected behavior? * After all, wouldn’t it be better to add one more judgment condition **? empty( $variations_groups[0] ),** * For now, I think the error no longer occurs during normal use, so I’ll mark it as resolved.
