我试图为prestashop制作一个模块覆盖某些功能。我想在后台写一个名为＆＃34; category＆＃34;的附件表单中添加一个字段。我做了这个修改：
Attachments.php：（在对象中添加了新字段）
<?php
class Attachment extends AttachmentCore
{
public $category;
public static $definition = array(
'table' => 'attachment',
'primary' => 'id_attachment',
'multilang' => true,
'fields' => array(
'file' => array('type' => self::TYPE_STRING, 'validate' => 'isGenericName', 'required' => true, 'size' => 40),
'mime' => array('type' => self::TYPE_STRING, 'validate' => 'isCleanHtml', 'required' => true, 'size' => 128),
'file_name' => array('type' => self::TYPE_STRING, 'validate' => 'isGenericName', 'size' => 128),
'file_size' => array('type' => self::TYPE_INT, 'validate' => 'isUnsignedId'),
/* Lang fields */
'name' => array('type' => self::TYPE_STRING, 'lang' => true, 'validate' => 'isGenericName', 'required' => true, 'size' => 32),
'description' => array('type' => self::TYPE_STRING, 'lang' => true, 'validate' => 'isCleanHtml'),
'category' => array('type' => self::TYPE_STRING, 'lang' => true, 'validate' => 'isGenericName', 'required' => true, 'size' => 128),
),
);
}
AdminProductsController.php：（整合字段）
<?php
class AdminProductsController extends AdminProductsControllerCore

Attachments.tpl：（仅限类别部分）
<div class="form-group">
<label class="control-label col-lg-3 required" for="attch_category_{$id_lang}">
{l s='Create category'}
</label>
<div class="col-lg-9">
{include
file="controllers/products/textarea_lang.tpl"
languages=$languages
input_name="attachment_category"
input_value=$attachment_category
}
</div>
问题是当我尝试上传文件时，我收到了这个错误：
意外的令牌＆lt;在位置0的JSON中 在chrome inspect network标签中，我有 Property Attachment-＆gt;类别为空
任何关于问题的想法？
