问题 In one of my recent project, the custom registration form is not working. When I click on the register button, it reloads the registration form, does not print any error and no data is inserted into the database. Here is the look of the registration form: Here is the migration file code: public function up() { Schema::create('users', function (Blueprint $table) { $table->increments('id'); $table->string('fname'); $table->string('lname'); $table->string('email')->unique(); $table->string(

问题 I would like to know how an action could be prevented on a model observer, for example: $model->update(['foo' => 'bar']); In the observer public function updating(Model $model) { if($model->isDirty('foo') { // Prevent action from happening } } Thank you in advance. 回答1: You can simply return false. As mentioned in the docs. http://laravel.com/docs/5.6/events#defining-listeners. Sometimes, you may wish to stop the propagation of an event to other listeners. You may do so by returning false

问题 I'm fairly new to Laravel and I'm currently working on a manual authentication for my project. I have tried Auth::attempt to validate the credentials that have been input, and I have seen that it works since I am being redirected to the page I wanted when it is authenticated. However, when I try to do Auth::check in the view I have been redirected to, it seems that it returns FALSE and does not read the authenticated user.

问题 I have 2 models in my app: 1. Customer.php 2. Car.php Now I would like to run a query that returns all customers that have less than 2 cars. Where 2 is a number that can be changed by the user. I have tried this but it didn't work, it just returns all customer records: $customers = Customer::whereHas("cars", function($query) { $query->selectRaw("count(*) < ?", [2]); }) ->get(); Edit: The two models are linked in a pivot table, meaning A customer can have more than 1 car and a Car can belong

问题 I'm using Laravel 5.6 with the following table structure: public function up() { Schema::create( 'traffic', function ( Blueprint $table ) { $table->string( 'id' ); $table->unsignedInteger( 'category_id' ); $table->unsignedInteger( 'magnitude_id' ); $table->unsignedInteger( 'start_id' )->nullable(); $table->unsignedInteger( 'destination_id' )->nullable(); $table->unsignedInteger('locale_id'); $table->integer( 'length' )->comment( 'in metres' ); $table->integer( 'delay' )->comment( 'in seconds'

问题 Heey! So I've recently been given the task to take a Laravel 5.2 up to 5.6. It seemed to be fine...until I tried to do a \Log::info() . Every time I run that, I get a big error, but at the end, it still prints to the log. I saw the 5.6 documentation on creating the config/logger.php . I took a fresh copy of it from github. The only thing I did after that was set an env variable for the LOG_CHANNEL to be single. Here's the error I get: [2018-03-02 08:28:59] laravel.EMERGENCY: Unable to create
