Question

我有一份提交文章的表格。该表单有一个类别多选框，使用我的Category.php实体从DB中提取类别。表单生成正常，但在尝试提交时出现以下错误：

Property "categories" is not public in class "Natknow\EditorBundle\Entity\Article". Maybe you should create the method "setCategories()"?

模板表单代码：

[...]
<div id="artFormG1">
    <?php echo $view['form']->row($form['title']) ?>
    <?php echo $view['form']->row($form['description']) ?>
    <?php echo $view['form']->row($form['source']) ?>
</div>

<div id="artFormG2">
    <?php echo $view['form']->row($form['categories']) ?>
</div>

<?php echo $view['form']->row($form['body']) ?>
<br />
<input class="button" type="submit" formnovalidate = "true" />

<?php echo $view['form']->rest($form) ?>

单挑：我使用命令行实用程序生成ArticleCategory.php实体，没有错误。但是，我并不是100％肯定它是为了做我想做的事。

Answer 1

您需要在文章实体中添加setCatagories（）才能超过发布的错误。

可能遇到其他问题。让许多表单按需运行可能会很棘手。

熟悉：

Answer 2

你应该将addArticleCategory()命名为addCategory()，然后Symfony（主人）才能认出它。

Answer 3

不要忘记使用：

Doctrine\Common\Collections\ArrayCollection;

和

public function __construct()
{
    $this->categories = new ArrayCollection();
}

（Article.php）

不确定这是不是问题，但我碰到了类似的事情。
