Question

我有一个用户需要填写的表单。它为用户提供了不同的输入标题，内容属于文档表，收件人输入属于用户表。我已根据用户表记录在我的收件人表单中提供了值。

问题：

我需要将用户在我的选择列表中的选择插入 recipients_received_documents （联结表）。以及当前登录的 user_id 。

形式：

<form class = "form-vertical" role = "form" method = "post" action = "{{ route('document.create')}}">

            <div class = "form-group">
                <label for = "title" class = "control-label">Title:</label>
                <input type = "text" name = "title" class = "form-control">

            </div>

            <div class = "form-group">

                <label for = "recipient" class = "control-label">To:</label>
                <select onChange = "showUserOptions(this)" name = "recipient[]" multiple class = "form-control" id = "myUserList">

                    @foreach ($result as $list)
                        <option value = "{{ $list->id }}">{{ $list->username }}</option>
                    @endforeach

                </select>

            </div>

            <div class = "form-group">
                <textarea id="content" name = "content"></textarea>

            </div>


            <div class = "form-group">
                <button type = "submit" class = "btn btn-primary" onclick="get_editor_content()">Send</button>
            </div>

            <input type = "hidden" name = "_token" value = "{{ Session::token() }}">

</form>

迁移：

users_table

public function up()
{
    Schema::create('users', function (Blueprint $table) {
        $table->increments('id');
        $table->string('username');
        $table->string('password');
        $table->string('remember_token');
        $table->timestamps();
    });
}

documents_table

public function up()
{
    Schema::create('documents', function (Blueprint $table) {
        $table->increments('id');
        $table->string('title');
        $table->text('content');
        $table->timestamps();
    });
}

recipients_received_documents 交汇表。

public function up()
{
    Schema::create('recipients_received_documents',function (Blueprint $table)
    {
        $table->increments('id');
        $table->integer('senderUserId')->unsigned();
        $table->integer('recipientUserId')->unsigned();
        $table->integer('docu_id')->unsigned();
        $table->foreign('senderUserId')->references('id')->on('users')->onDelete('cascade');
        $table->foreign('recipientUserId')->references('id')->on('users')->onDelete('cascade');
        $table->foreign('docu_id')->references('id')->on('documents')->onDelete('cascade');
        $table->dateTime('dateReceived')->default(DB::raw('CURRENT_TIMESTAMP'));
    });
}

DocumentController：

public function getDocuments()
{
    $result = DB::table('users')->where('id', '!=', Auth::id())->get();

    return view ('document.create')->with('result', $result);
}

public function postDocuments(Request $request)
{

    $this->validate($request,
    [
        'title' => 'required|alpha_dash|max:255',
        'recipient' => 'required',
        'content' => 'required',
    ]);

    $title = $request['title'];
    $content = $request['content'];

    $document = new Document();
    $document->title = $title;
    $document->content = $content;

    $document->save();

    return redirect()->back();  
}

我在这里有点迷惑我不知道如何将recipient表单保存到联结表中，因为它属于文档表。任何帮助将不胜感激！

我认为这个链接可以帮到你，当我需要学习旋转时，这对我很方便：http://laraveldaily.com/pivot-tables-and-many-to-many-relationships/

此外，在您的模型中实际获取当前的Authed用户ID，您可以使用Eloquent Model Events：https://laravel.com/docs/5.2/eloquent#events

recipients_received_documents 模型应添加以下（请注意，如果您的模型位于任何命名空间下，则需要在命名空间声明下方添加use Auth; ）

public static function boot(){
    parent::boot(); // <-- Don't forget this

    self::creating(function($model){
        $model->auth_id = Auth::user()->id;
    });
}

希望这有帮助！
