[英]How to pass a value from one controller to another controller in laravel
[英]laravel pass parameter from one controller to another controller to view
我是laravel的新手,所以我有2個桌子:
每次用戶登錄時,他們都可以創建帳戶並將其信息放入頁面中。 我有桌子 :
public function up() {
Schema::create('users', function($table) {
$table->increments('id');
$table->string('email')->unique();
$table->boolean('remember_token');
$table->string('password');
$table->timestamps();
});
和
Schema::create('accounts', function($table) {
# AI, PK
$table->increments('id');
# created_at, updated_at columns
$table->timestamps();
# General data...
$table->integer('user_id')->unsigned();
$table->string('name_first');
$table->string('name_last');
$table->date('dob');
$table->string('address');
$table->string('phone');
$table->string('email')->unique();
$table->string('event');
# Define foreign keys...
$table->foreign('user_id')
->references('id')
->on('users');
});
然后我有我的視圖create.blade.php表單信息:
{{Form :: open(array('url'=>'accounts'))}}
<div class="form-group">
{{ Form::label('name_first', 'Frist Name') }}
{{ Form::text('name_first', Input::old('name_first'), array('class' => 'form-control')) }}
</div>
<div class="form-group">
{{ Form::label('name_last', 'Last Name') }}
{{ Form::text('name_last', Input::old('name_last'), array('class' => 'form-control')) }}
</div>
<div class="form-group">
{{ Form::label('dob', 'DOB') }}
{{ Form::text('dob', Input::old('dob'), array('class' => 'form-control')) }}
</div>
<div class="form-group">
{{ Form::label('phone', 'Phone Number') }}
{{ Form::text('phone', Input::old('phone'), array('class' => 'form-control')) }}
</div>
<div class="form-group">
{{ Form::label('address', 'Mailing Address') }}
{{ Form::text('address', Input::old('address'), array('class' => 'form-control')) }}
</div>
<div class="form-group">
{{ Form::label('email', 'Email') }}
{{ Form::email('email', Input::old('email'), array('class' => 'form-control')) }}
</div>
<div class="form-group">
{{ Form::label('event', 'Party/Event') }}
{{ Form::select('event', array('0' => 'Birthday', '1' => 'Baby Shower', '2' => 'Wedding', '3' => 'Anniversary'), Input::old('party'), array('class' => 'form-control')) }}
</div>
{{ Form::submit('Adding RSVP now!', array('class' => 'btn btn-primary')) }}
{{ Form::close() }}
</div>
我試圖從表單中獲取view的所有值,並從用戶表中獲取所有電子郵件的視圖...但我一直在下面收到此錯誤:我從哪里來。 推薦會很可愛,謝謝
Illuminate \ Database \ QueryException (23000)
SQLSTATE[23000]: Integrity constraint violation: 1452 Cannot add or update a child row: a foreign key constraint fails (`authapp`.`accounts`, CONSTRAINT `accounts_user_id_foreign` FOREIGN KEY (`user_id`) REFERENCES `users` (`id`)) (SQL: insert into `accounts` (`name_first`, `name_last`, `dob`, `address`, `phone`, `email`, `event`, `updated_at`, `created_at`) values (jea, las, 21, ;lsdkfj, ;fd, iamjeannie@gmail.com, 3, 2014-08-10 01:14:07, 2014-08-10 01:14:07))
@JPC,
從我對您的查詢的了解來看,您正在嘗試將記錄插入到account表中,並且遇到了錯誤。
因為在帳戶表中有一個“ user_id”字段,該字段引用了用戶表中的用戶記錄,所以在帳戶表中執行插入操作時,還必須為此字段提供一個值,否則會出現外來違反密鑰,那就是您的錯誤所在。
您可以通過以下方式在表單本身中添加一個隱藏字段來做到這一點:
{{ Form::hidden('user_id', $id) }}
或通過以下方式抓住登錄用戶:
Auth::user()->getId() or something
試試這個,讓我知道。
