Drupal 8自定义字段//原始错误

我在节点编辑页面上看到文本字段和ckeditor字段，但是当我尝试保存节点时，我收到“该值应该是正确的原始类型”错误。Drupal 8自定义字段//原始错误

<?php

class ProgramItem extends FieldItemBase implements FieldItemInterface { 

    public static function schema(FieldStorageDefinitionInterface $field_definition) { 
    return array(
     'columns' => array(
     'date' => array(

      'type' => 'varchar',

    return empty($value);

    } 

} 



    <?php 
namespace Drupal\custom_field\Plugin\Field\FieldWidget; 

use Drupal\Core\Field\FieldItemListInterface; 
use Drupal\Core\Field\WidgetBase;

class ProgramWidget extends WidgetBase implements WidgetBaseInterface { 

    /**

    public function formElement(FieldItemListInterface $items, $delta, array $element, array &$form, FormStateInterface $form_state) { 

    $element['date'] = array(
     '#type' => 'textfield', 
     '#title' => $this->t('Date'), 
     '#placeholder' => $this->getSetting('placeholder_date'), 
     '#default_value' => isset($items[$delta]->date) ? $items[$delta]->date : NULL, 
     '#required' => $element['#required'], 
    ); 



    $element['programmation'] = array(
     '#type' => 'text_format', 
     '#title' => $this->t('Programmation'), 
     '#placeholder' => $this->getSetting('placeholder_programmation'), 
     '#default_value' => isset($items[$delta]->programmation) ? $items[$delta]->programmation : NULL, 
     '#format' => 'full_html', 
    ); 

    $element['field_widget_display']['#access'] = true; 
    $element['field_widget_display_settings']['#access'] = true; 

    die('ProgramWidget'); 

    return $element; 
    } 

}

我看到我可以在WidgetBase中使用massageFormValues（）方法，但我不知道如何使用它。

有一点帮助是值得欢迎的。

谢谢

finaly我添加到ProgramWidget：

/** 
    * {@inheritdoc} 
    */ 
    public function massageFormValues(array $values, array $form, FormStateInterface $form_state) { 

     foreach ($values as &$value) { 
     if (count($value['programmation'])) { 
      $value['programmation'] = $value['programmation']['value']; 
     } else { 
      $value['programmation'] = $value['programmation'] !== '' ? $value['programmation'] : '0'; 
     } 
     } 

    return $values; 

    } 

}

而现在s工作

谢谢，它也适用于我 –

您试图设置一个varchar到5000字符的大小，但它仅允许255 你的错误：

'type' => 'varchar', 
    'length' => 5000, // change it to 255 
    'size' => 'normal' // delete this line

如果您需要5000字的使用TEXT类型，你不需要精确的“大小”属性，这只是对整数

感谢您的回答，但我有同样的错误：■ –

@FrankDrebin我编辑我的职务 – Fky

似乎因为

$element['programmation'] = array(
     '#type' => 'text_format', 
     '#title' => $this->t('Programmation'), 
     '#placeholder' => $this->getSetting('placeholder_programmation'), 
     '#default_value' => isset($items[$delta]->programmation) ? $items[$delta]->programmation : NULL, 
     '#format' => 'full_html', 
    );

但我不知道如何覆盖方法massageFormValues ..？

添加paranthesis到条件'#default_value'=>（isset（$ items [$ delta] - > programmation）？$ items [$ delta] - > programmation：NULL） – Fky
