How To Resolve Call to Undefined Function str_random() Error in Laravel? |
Understanding the Error
The error Call to undefined function App\Http\Controllers\str_random() happens when you try to use the str_random() function, which is no longer defined in Laravel as of version 6. This function was originally part of the global helper functions provided by Laravel but was removed in favor of a more standardized approach using the Str facade.
The problem typically arises when upgrading a Laravel project to a version where str_random() has been removed or when using old code from earlier versions of Laravel.
The Cause of the Error
Laravel 6 introduced a shift in how certain helper functions were managed. The str_random() function was deprecated and eventually removed because it wasn’t part of the consistent API Laravel aimed to offer. Instead of using global functions, Laravel’s newer versions encourage developers to utilize facades for better organization, testability, and consistency.
The str_random() function was replaced by Str::random(), a method in the Str facade. So, when you try to use str_random() in Laravel 6 or later, you encounter the Call to undefined function error.
How to Fix the Error
To resolve the error, you need to replace the deprecated str_random() function with the Str::random() method. Let’s walk through how you can do that.
Step 1: Import the Str Facade
To use Str::random(), you need to import the Str facade at the top of your controller or class. This is done using the following line:
use Illuminate\Support\Str;
Step 2: Update Your Code
Once the Str facade is imported, you can update any instances of str_random() to Str::random().
For example, suppose you have code like this that generates a random filename:
$option->option_value = $request->app_logo->move('uploads/settings/', str_random(20) . '.' . $request->app_logo->extension());
You should update it to use Str::random() like this:
