Have just pushed `1.7.4` update that should address these notices. Please test and report back if you might find any further issues. * Thread Starter [koolpal](https://wordpress.org/support/users/koolpal/) * (@koolpal) * [4 years, 7 months ago](https://wordpress.org/support/topic/multiple-php-notices-7/#post-15022163) * Hi, * Thank you for the prompt reply and the quick update. * I have updated to 1.7.4 * With this update, the above reported notices have gone. Thanks a lot. * Now when I navigate to Woocommerce -> Customer History -> Products I get the below notices: * `Notice: Undefined offset: 0 in [path]\wp-content\plugins\order-status-history- for-woocommerce\includes\admin\order-history-product.php on line 160` * `Notice: Undefined offset: 1 in [path]\wp-content\plugins\order-status-history- for-woocommerce\includes\admin\order-history-product.php on line 162` * Please review and guide / fix. * Thanks again. * Take care, stay safe! * Thread Starter [koolpal](https://wordpress.org/support/users/koolpal/) * (@koolpal) * [4 years, 7 months ago](https://wordpress.org/support/topic/multiple-php-notices-7/#post-15035842) * [@alx359](https://wordpress.org/support/users/alx359/) I dug a bit into the notices and the source and found that it seems to be linked to the treatment of support for composite products and their components. * My store does not use a composite product / components. * Is there some other way to use this awesome plugin without errors? * Thanks * Plugin Author [alx359](https://wordpress.org/support/users/alx359/) * (@alx359) * [4 years, 7 months ago](https://wordpress.org/support/topic/multiple-php-notices-7/#post-15051800) * Hi [@koolpal](https://wordpress.org/support/users/koolpal/) , * Sorry for the late reply. I didn’t receive the WP support email for some reason, and few moments back noticed your reply by chance. * I’ve pushed 1.7.5 update addressing the described issue. Please test and report back if you may find any further issues. * Thanks. * Thread Starter [koolpal](https://wordpress.org/support/users/koolpal/) * (@koolpal) * [4 years, 6 months ago](https://wordpress.org/support/topic/multiple-php-notices-7/#post-15062026) * [@alx359](https://wordpress.org/support/users/alx359/) Thank you for your update. * I updated the plugin to v 1.7.5 and I STILL observe the below recurring notices when I navigate to Woocommerce -> Customer History -> Products * `Notice: Undefined offset: 0 in [path]\wp-content\plugins\order-status-history- for-woocommerce\includes\admin\order-history-product.php on line 161` * `Notice: Undefined offset: 1 in [path]\wp-content\plugins\order-status-history- for-woocommerce\includes\admin\order-history-product.php on line 163` * Please review and guide / fix. * Thanks again! * Plugin Author [alx359](https://wordpress.org/support/users/alx359/) * (@alx359) * [4 years, 6 months ago](https://wordpress.org/support/topic/multiple-php-notices-7/#post-15064330) * Hi [@koolpal](https://wordpress.org/support/users/koolpal/), thanks for your feedback. I’ve pushed `1.7.5.1` that hopefully fixes the issue for you this time. Thanks. * Thread Starter [koolpal](https://wordpress.org/support/users/koolpal/) * (@koolpal) * [4 years, 6 months ago](https://wordpress.org/support/topic/multiple-php-notices-7/#post-15066373) * [@alx359](https://wordpress.org/support/users/alx359/) Sorry, but even with 1.7.5.1 I am **STILL **getting the recurring notices when I navigate to Woocommerce - > Customer History -> Products * `Notice: Undefined offset: 0 in [path]\wp-content\plugins\order-status-history- for-woocommerce\includes\admin\order-history-product.php on line 161` * `Notice: Undefined offset: 1 in [path]\wp-content\plugins\order-status-history- for-woocommerce\includes\admin\order-history-product.php on line 163` * Please review and guide / fix. * Plugin Author [alx359](https://wordpress.org/support/users/alx359/) * (@alx359) * [4 years, 6 months ago](https://wordpress.org/support/topic/multiple-php-notices-7/#post-15068114) * Hi [@koolpal](https://wordpress.org/support/users/koolpal/), * Hmm, that’s strange, it feels like some sort of a cache issue now, as in `1.7.5.1` such notices shouldn’t happen anymore. * Would you please check the code in `/wp-content/plugins/order-status-history- for-woocommerce/includes/admin/order-history-product.php`. Starting from `line 159` it should read like this: * ``` # support for composite products and their components $meta_data = $item->get_meta_data(); $item_data = is_object( $meta_data[0] ) ? $meta_data[0]->get_data() : array(); $is_composite = !empty( preg_grep('/.*component.*/i', flatten_array( $item_data ) ) ); $item_data = is_object( $meta_data[1] ) ? $meta_data[1]->get_data() : array(); $is_component = !empty( preg_grep('/.*component.*/i', flatten_array( $item_data ) ) ); ``` * If the above code block looks the same, would please comment out lines `161` and `163`, and see what you get in the `debug.log` after a product page refresh? The path to that page should actually be: * `Woocommerce menu > Customer History menu > 'Orders History' button > Products tab` * Thank you. * Thread Starter [koolpal](https://wordpress.org/support/users/koolpal/) * (@koolpal) * [4 years, 6 months ago](https://wordpress.org/support/topic/multiple-php-notices-7/#post-15068465) * [@alx359](https://wordpress.org/support/users/alx359/) Thank you for your continued interest in trying to fix this for me! I really appreciate this. * I could see the code as mentioned by you. * When I commented out lines 161 and 163 and refreshed the Product tab, I get a fatal error with the below in debug.log * ``` [15-Nov-2021 09:30:18 UTC] PHP Notice: Undefined variable: item_data in [path]wp-content\plugins\order-status-history-for-woocommerce\includes\admin\order-history-product.php on line 162 [15-Nov-2021 09:30:18 UTC] PHP Fatal error: Uncaught TypeError: Argument 1 passed to oshwoo\flatten_array() must be of the type array, null given, called in [path]wp-content\plugins\order-status-history-for-woocommerce\includes\admin\order-history-product.php on line 162 and defined in [path]wp-content\plugins\order-status-history-for-woocommerce\includes\php_ext.php:57 Stack trace: #0 [path]wp-content\plugins\order-status-history-for-woocommerce\includes\admin\order-history-product.php(162): oshwoo\flatten_array(NULL) #1 [path]wp-content\plugins\order-status-history-for-woocommerce\includes\admin\order-history.php(40): include('F:\\laragon\\www\\...') #2 [path]wp-content\plugins\order-status-history-for-woocommerce\includes\class_osh.php(219): include('F:\\laragon\\www\\...') #3 [path]wp-includes\class-wp-hook.php(303): oshwoo\osh->add_order_history('') #4 [path]wp-includes\class-wp-hook.php(327): WP_Hook->apply_filters('', Arr in [path]wp-content\plugins\order-status-history-for-woocommerce\includes\php_ext.php on line 57 ``` * Please review and guide. * Thanks * Thread Starter [koolpal](https://wordpress.org/support/users/koolpal/) * (@koolpal) * [4 years, 6 months ago](https://wordpress.org/support/topic/multiple-php-notices-7/#post-15068504) * [@alx359](https://wordpress.org/support/users/alx359/) If it helps, I did some trial and error and made the following changes to make it error free (so far! I don’t know what else I broke) * `/wp-content/plugins/order-status-history-for-woocommerce/includes/admin/order- history-product.php` * I removed 1. Line 160 to line 164 2. Line 179 to line 181 and line 183 3. Line 188 to line 190 and line 192 * After this the Product Tab works for me without any errors in debug.log. * Does this help you in any way? * Thanks again for such a persistent interest in solving this issue. * Plugin Author [alx359](https://wordpress.org/support/users/alx359/) * (@alx359) * [4 years, 6 months ago](https://wordpress.org/support/topic/multiple-php-notices-7/#post-15069189) * Hi [@koolpal](https://wordpress.org/support/users/koolpal/), yes, getting rid of the composite support code shall indeed fix the issue, but I need that support to remain as I do actually use it. * Would you please return all code back to unedited state and instead for a moment add a new line of test code after line `160` this way: * ``` # support for composite products and their components $meta_data = $item->get_meta_data(); error_log( var_export( $meta_data ), true ) ); #<--add this line ``` * and after reloading the products tab page send me the `debug.log` results to @gmail . * (You may clear any identifiable data if you want. I only need to know what’s so special about that `$meta_data` variable you got that’s still giving such issue.) * Thanks for your help. * Thread Starter [koolpal](https://wordpress.org/support/users/koolpal/) * (@koolpal) * [4 years, 6 months ago](https://wordpress.org/support/topic/multiple-php-notices-7/#post-15071937) * [@alx359](https://wordpress.org/support/users/alx359/) I have sent you the email just now.
