![]() When things are not under your control, like, you need to get an array from an outside variable, do a validation first. Added support for Opencart 3.0.3.7 and PHP 7.4 (Opencart 3.0.3.6 and lower still doesnt work with PHP 7.4, use PHP 7.3 in that case). And this error message will help you to pinpoint this problem. Unless, due to some mistake, your code will return a non-array value unexpectedly. And you won't see this error message again. So, as a rule, just make sure that every function that should return an array, returns an array, or any variable that should contain an array, contains an array. Therefore, you need to fix the code that assigns value to $cOTLdata. Definitely, $cOTLdata contains null while your code expects it to be an array. But if you get a null value where array is expected, it means that the data flow in your program is broken. You can only use array offset on arrays, special type of objects and (using only numeric indices) on strings. It just makes not sense to access a null or a non-existent variable as s though it's array. This way you won't have to silence them, and every error would mean that your code indeed encountered a bug. It means that errors shouldn't be intentional or "habitual". But you should really consider doing the former.Įvery error message helps you to find a bug in the code. ![]() Sadly, the accepted answer only elaborates on the latter. When your code contains a bug, your best bet is to fix it, not to brush it off. Which definitely means that logic of your program is broken.įirst of all you must understand that every error message PHP generates is meant to help you, and to make your code cleaner and less error-prone. That usually makes a 10 lines controller into 50 or 60 lines one… Some heavier controllers have in excess of 150 lines just to map the languages !? Then we move on to the form handling.This error means that you are trying to use a null (or a non-existent value) as array. So, we load the language file and manually map ALL the entries from the simple array that each language file is, to a new array with the exact same key as the language string. $this->data = $this->language->get('text_newsletter') $this->data = $this->language->get('text_transaction') $this->data = $this->language->get('text_return') $this->data = $this->language->get('text_reward') $this->data = $this->language->get('text_download') $this->data = $this->language->get('text_order') $this->data = $this->language->get('text_wishlist') $this->data = $this->language->get('text_address') $this->data = $this->language->get('text_password') $this->data = $this->language->get('text_edit') $this->data = $this->language->get('text_my_newsletter') $this->data = $this->language->get('text_my_orders') $this->data = $this->language->get('text_my_account') ![]() $this->data = $this->language->get('heading_title') The system is FULL of code like the following: Simple logic dictates that transactions are a fundamental part of e-commerce, but apparently the team behind OpenCart decided thats not that case!? I am already stunned but lets not stop here… MyIsam doesn’t support foreign keys either, so all integrity and constraint checks are done with PHP, nasty… Code Repetition The engine of choice for ALL tables, including orders is MyIsam, which first of all shouldn’t even be a consideration in any MySql 5+ setup really, especially for web purposes and second and more important maybe IT DOEST SUPPORT TRANSACTIONS. So lets start with the obvious… A quick peak at the installation sql schema reveals something mind-boggling.
