symfony的注意：數組字符串轉換choicetype多維

我與symfony的2.8 choicetype一個問題，我試圖做到這一點symfony的注意：數組字符串轉換choicetype多維

我改變事件的實體像這樣

public function setDisciplineLevels($disciplines_to_order) { 
    $levelsbydiscipline = array(); 
    foreach($disciplines_to_order as $disciplines) { 
     if(!array_key_exists($disciplines['discipline'], $levelsbydiscipline)){ 
      $levelsbydiscipline[$disciplines['discipline']] = array(); 
     }  
     $levelsbydiscipline[$disciplines['discipline']][$disciplines['teacherdiscipline_id'].$disciplines['level_id']]= $disciplines['title']; 

    } 
    $this->disciplinelevels= $levelsbydiscipline; 

    return $this; 
}

我的陣列結果： My array like sample

在我的表單代碼

->add('disciplinelevels', ChoiceType::class, array(
       'choices_as_values' => true, 
       'multiple' => true, 
       //'expanded' => true 
      ));

但每次我有一個錯誤：請注意數組字符串轉換

看來問題來自於方法： getDisciplineLevels

我做到這一點的形式，結果是正確的，當，但我需要更改名稱它的確定與水平，但不與disciplinelevels：

->add('level', ChoiceType::class, array(
       'choices'=>array('informatique' => array(
        '123'=>'Debutant', 
        '345'=>'Confirme', 
        '678'=>'Expert' 
       )), 
       'choices_as_values' => false, 
       'multiple' => false, 
       'expanded' => false 
      ));

stack trace

我實體事件

當你提交你的表格或在表單出現之前你有問題嗎？，並且如果可能，你可以顯示爲你的班級 – ahmedbhs

你的示例數組中的選擇值（提交給後端的數據）和選擇標籤（顯示爲選項的名稱）應該是什麼？應該按照第一級別鍵（屏幕截圖中的「Informatique」）對值進行分組？ – nifr

問題是在渲染表單女巫類之前你需要實體嗎？是的'Informatique'是第一級 - >和第二級是

在控制器上的呼叫從實體誰原始數組轉換爲多維數組

**** ****控制器

$masterclass->setDisciplineLevels($disciplines_teacher_current);

****實體法****

在實體添加到私人屬性與getter和setter和一個特殊的方法__toString將每個結果從表單轉換爲字符串兩個最後的方法是用於克表格，顯示選擇

/* 
* @var array 
*/ 
private $disciplinelevels; 

/* 
* @var string 
*/ 
private $listdisciplinelevels; 

/* 
* @var string 
*/ 

public function __toString() { 
    return $this->listdisciplinelevels; 
} 

/* GETTERS AND SETTERS */ 

/* 
* Get levels by discipline convert initial arrayt to multidimensionnal 
* 
* @return \TR\MainBundle\Entity\Event 
*/ 

public function setDisciplineLevels($disciplines_to_order = array()) { 
    $levelsbydiscipline = array(); 
    foreach($disciplines_to_order as $disciplines) { 
     if(!array_key_exists($disciplines['discipline'], $levelsbydiscipline)){ 
      $levelsbydiscipline[$disciplines['discipline']] = array(); 
    } 
     $levelsbydiscipline[$disciplines['discipline']][$disciplines['teacherdiscipline_id'].$disciplines['level_id']]= $disciplines['title']; 

    } 

    $this->disciplinelevels= $levelsbydiscipline; 
    return $this; 
} 

/** 
* Get levels by discipline 
* 
* @return array 
*/ 
public function getDisciplineLevels() { 
    return $this->disciplinelevels; 
} 

function getListdisciplinelevels() { 
    return $this->listdisciplinelevels; 
} 

function setListdisciplinelevels($listdisciplinelevels) { 
    $this->listdisciplinelevels = $listdisciplinelevels; 
}

` **** **** FORM

你需要獲取類數組您在控制器

$eventinit = $builder->getData();

之前設置

然後，您只需要使用方法__toString使用的屬性名稱創建choiceType元素，然後使用getter的對象調用多維數組

->add('ListDisciplineLevels', ChoiceType::class, array(
    'placeholder'=>'Do a choice', 
    'choices' => $choice = $eventinit->getDisciplineLevels(), 
    'choices_as_values' => false, 
));
