Question

在AppBundle \ Etity \ Image我有：

    @Override
    public void onClick(View v) {
        Random r = new Random();
        int id = r.nextInt(mItemBook.numItems());
        String item = mItemBook.getItem(id);
        int pic = mItemBook.getImg(id);

        // Update text view with item
        mInfoText.setText(item);
        mImage.setImageResource(pic);

在AppBundle \ Entity \ Post.php中使用的是这样的：

Random

在AppBundle \ Form \ Type \ PostType.php中我有：

由于某种原因，图像没有上传到指定目录（或其他任何地方），我不确定我做错了什么。任何见解我都会感激不尽。谢谢。

问题与

有关

return __DIR__ . '/../../../../web/' . $this->getUploadDir();

在这种情况下，我将上一行更改为：

return __DIR__ . '/../../../web/' . $this->getUploadDir();

这是因为我的实体位于src / AppBundle / Entity中并且要转到根目录，它需要跳回3个目录。在实体中对路径进行硬编码也是一个坏主意。我相应地修改了我的例子。
