Question

我已经搜索了论坛并看到了很多类似的问题，但似乎没有一个问题可以解决我的问题。我相信这是不同的，因为：

此时未使用表单验证
表单方法似乎没有关系（只有1个帖子后）
路由未包含在Web中间件

这是应用程序应该做的事情：

用户（带或不带身份验证）查看带有表单（display_event）
用户选择特定故障单进行排序，并定向到第二个表单（register_step1）
然后，用户会根据订购的票数填写人口统计信息
处理步骤，如果使用的电子邮件地址是有效用户（在DB中），则应返回步骤2中的表格＆amp; 3，填充字段并闪烁消息。否则它将执行所需的save（）操作。（register_step2）

web.php的相关路线如下：

    Route::get('/events/{event}', 'EventController@show')->name('display_event');
    Route::post('/register/{event}', 'RegistrationController@showRegForm')->name('register_step1');
    Route::post('/register/{event}/create', 'RegistrationController@store')->name('register_step2');

RegistrationController.php的相关部分在这里：

public function showRegForm (Request $request, $id) {
    // Registering for an event from /event/{id}
    $ticket        = Ticket::find(request()->input('ticketID'));
    $quantity      = request()->input('quantity');
    $discount_code = request()->input('discount_code');
    $event         = Event::find($ticket->eventID);
    return view('v1.public_pages.register', compact('ticket', 'event', 'quantity', 'discount_code'));
}

并且：

public function store (Request $request) {

    $event = Event::find(request()->input('eventID'));
    if(Auth::check()) {
        $this->currentPerson = Person::find(auth()->user()->id);
    }

    // set up a bunch of easy-reference variables from request()->input()

    $email = Email::where('emailADDR', $checkEmail)->first();

    if(!Auth::check() && $email === null) {
        // Not logged in and email is not in database; must create
        $person               = new Person;
        // add person demographics from form

    } elseif(!Auth::check() && $email !== null) {
        // Not logged in and email is in the database;
        // Should force a login -- return to form with input saved.

        flash("You have an account that we've created for you. 
               Please attempt to login and we'll send you a password to your email address.", 'warning');

        return back()->withInput();

    } elseif(Auth::check() && ($email->personID == $this->currentPerson->personID)) {
        // the email entered belongs to the person logged in; ergo in DB
        $person         = $this->currentPerson;
        // add person demographics from form

    } elseif(Auth::check() && ($email->personID != $this->currentPerson->personID)) {
        // someone logged in is registering for someone else in the DB
        $person         = Person::find($email->personID);
        // add person demographics from form

    } else {
        // someone logged in is registering for someone else NOT in the DB
        $person               = new Person;
        // add person demographics from form
    }

    // do more stuff...
    $reg  = new Registration;  (set up a registration record)
}

Answer 1

我接受了@ apokryfos评论中指出的建议，并将表单解析后显示脚本从POST更改为get。

redirect（） - ＆gt; back（）显然总是一个method = get，这是MethodNotAllowedHttpException的原因。在使用Laravel的~2周内，我还没有遇到过这个事实。

使用Laravel 5.4中的return back（） - ＆gt; withInput（）生成MethodNotAllowedHttpException
