Just another November 11

Coding. AI-ng solutions. Reading concepts. *The loop. *

We sometimes stumble on problems that we've already encountered before but cared to little to remember the concept or solution.

Just another day as a wip programmer here. Here's what I noted today.

1. in php, function type: removeFiles() : string you can use ?string which means nullable return, so its either string or null
2. in php, to throw exceptions that can be handle by catch(): use throw new Exception("the error")
3. PHP falsy values that can be catch by !$variableName: null, false, 0, '0', '', []
4. in Laravel, return self::where('order_code', $orderCode)->get() this is an Eloquent query: returns a collection.
5. in Laravel, if you manually add models and controllers - you need to run composer dump-autoload php artisan optimize:clear
6. in Laravel data validation, to check for uniqueness use this: unique:table,column,except_id | unique:tblSample,name,' . $request->id
7. in tailwind CSS, element auto fill the available space use: grid-cols-[repeat(auto-fit,minmax(200px,1fr))]
8. in HTML, to disable tab stop for specific elements add: tabIndex={-1}

Disclaimer: These are concepts I noted for myself; the grammar isn’t polished - just for me to remember the things.
