[2017-05-08 09:33:27] local.ERROR: ErrorException: Creating default object from empty value in /var/www/html/laravel-project/app/Http/Controllers/ServerController.php:171

In the above log file named laravel.log, it is said that there is an error which is shown exactly stated in the title of this article. The error itself is generated by a script or snippet code within an article named ‘ServerController.php’ which is a Controller file in this part of section :

public function checkGeneralInfo(Request $request) {
        $server->type = $request->input("type");
        $server->serial_number = $request->input("serial_number");
        $server->label = $request->input("label");
        $server->ip_internal = $request->input("ip_internal");
        $server->ip_public = $request->input("ip_public");
        $server->ip_management = $request->input("ip_management");
        $server->label = $request->input("label");
        $server->year = $request->input("year");
        $server->warranty = $request->input("warranty");
}

The above snippet code is a method within controller file named checkGeneralInfo. It is written to retrieved information from a blade view template file which has a form defined in it. The form itself has several input fields with the names of each field ranging from the type until the warranty of the server. User will input all of the data in the input fields inside the form defined in the blade view file template. And apparently, the error specified, ‘Creating default object from an empty value’, it is because the object hasn’t been instantiated or hasn’t been created. So, it is considered as an empty value. The object in this context is represented with a variable named $server. To solve the error generated, the following line of code is needed to be inserted to be able to create or to instantiate the object represented with a variable named $server :

        $server = new Server();

So, the overall snippet code will be written as follows :

public function checkGeneralInfo(Request $request) {
        $server = new Server(); 
        $server->type = $request->input("type");
        $server->serial_number = $request->input("serial_number");
        $server->label = $request->input("label");
        $server->ip_internal = $request->input("ip_internal");
        $server->ip_public = $request->input("ip_public");
        $server->ip_management = $request->input("ip_management");
        $server->label = $request->input("label");
        $server->year = $request->input("year");
        $server->warranty = $request->input("warranty");
}
