CakePHP3よく使ってるなと思うコマンドメモ

$Session = $this->request->getSession();
$Session->check('shikibetsu_name');

$SessionId = $Session->id;

Table.php

use Cake\ORM\TableRegistry;
$CompaniesTable = TableRegistry::getTableLocator()->get('Companies');

//有無のチェック
$Company = $CompaniesTable->find()->where(['id' => $id])->first();
//firstを使う。get($id)だとない場合エラーになるので判定までいけない
if($Company){
//あった場合の処理
}else{
//なかった場合の処理
}

$Company = $CompaniesTable->newEntity($Data);//InsertEntity
$Company = $CompaniesTable->patchEntity($Company,$Data);//UpdateEntity

if ($Company->getErrors()) {
//バリデーションエラー処理
}

if ($Company = $CompnaiesTable->save($Company)) {
//save成功処理
}else{
//seve失敗処理
}

Email.php

use Cake\Mailer\Email;
$Email = new Email('sakura');
$Email->setEmailFormat('text')
->setViewVars(['user_name' => $user_name, 'age' => $age]);
