Framework Error

What This Error Means

This error occurs when a route in a PHP framework application is called with a missing parameter, and the route's default value for that parameter is not defined.

Why It Happens

This error typically happens when a developer forgets to pass a required parameter to a route in their PHP framework application, or when the route is defined without a default value for that parameter.

How to Fix It

1. 1To fix this error, add the missing parameter to the route URL or define a default value for the parameter in the route definition. For example, if the route is defined as follows:
2. 2// Before (broken code)
3. 3$router->get('/users/{id}', 'UserController::show');
4. 4// After (fixed code)
5. 5$router->get('/users/{id}', 'UserController::show', ['id' => 1]);
6. 6// or
7. 7$router->get('/users', 'UserController::show');
8. 8// if the route should be accessible without the 'id' parameter

Example Code Solution

define('routes', function() {
    $router->get('/users/{id}', 'UserController::show');
});

define('routes', function() {
    $router->get('/users', 'UserController::show');
    // or
    $router->get('/users/{id}', 'UserController::show', ['id' => 1]);
});
