XML中的表单字段-
<field name="invoice" type="file"/>
您可以使用php
move\u uploaded\u file()
函数
//import joomlas filesystem functions, we will do all the filewriting with joomlas functions
jimport('joomla.filesystem.file');
jimport('joomla.filesystem.folder');
//this is the name of the field in the html form, filedata is the default name for swfupload
$fieldName = 'Filedata';
//the name of the file in PHP's temp directory that we are going to move to our folder
$fileTemp = $_FILES[$fieldName]['tmp_name'];
//always use constants when making file paths, to avoid the possibilty of remote file inclusion
$uploadPath = JPATH_SITE.DS.'path'.DS.'path'.DS.$fileName;
if(!JFile::upload($fileTemp, $uploadPath))
{
echo JText::_( 'ERROR MOVING FILE' );
return;
}
else
{
//Updating the db with the $fileName.
$db =& JFactory::getDBO();
$query = $db->getQuery(true);
$query->update($db->nameQuote(TABLE_PREFIX.'table_name'));
$query->set($column.' = '.$db->quote($fileName));
$query->where($db->nameQuote('id').'='.$db->quote($id));
$db->setQuery($query);
$db->query();
}
$column-文件的db列名
$fileName-文件名
如果文件上传成功,将运行查询。我遇到了相同的问题,也许我们可以一起继续。这是我的密码: /管理员/components/com_comp_name/models/forms/edit.xml

在请求变量中设置文件名,因为它现在是$\u FILES变量
JRequest::setVar('jform[invoice]',$file['name']['invoice'] );
//完整代码
class InvoiceManagerControllerInvoiceManager extends JControllerForm

function save(){
$file = JRequest::getVar('jform', null, 'files', 'array');

// Move the uploaded file.
JFile::upload( $file['tmp_name']['invoice'], $filepath );
JRequest::setVar('jform[invoice]',$file['name']['invoice'] );
}
return parent::save();
}
}
在Joomla3.2.x上,我必须重写模型类的save函数,将上传的文件名保存到db,如下所示
public function save($data){
$input = JFactory::getApplication()->input;
$files = $input->files->get('jform');
$fieldName = 'thumbnail';
$data['thumbnail'] = $files[$fieldName]['name'];
return parent::save($data);
}
文件已成功保存在磁盘上。我只需要在上传后将其名称存储在数据库中。谢谢Dasun,现在上传文件就可以了。我一直在更新数据库:/I我按照你提到的那样做了。但它不起作用:/这是我的组件中的文件保存部分-。。将$invoice列替换为$invoice,该VARCHAR位于我的表中。var_dump为$db-您缺少JFile::upload($fileTemp,$uploadPath)的if语句。请正确参考eg并更改代码。若你们遇到任何问题,请提问。嗯,我认为问题来自于询问$未定义列($invoice,在我的情况下)。这里是修改后的代码-var_dump of$db-我认为我们应该将修改后的$data传回POST方法,因为parent::save()返回到系统save()。不知何故,如果我将$data添加到save()函数中,它就不会得到很好的效果。保存所有内容,但数据库中只有文件字段为空。您是否找到了执行此操作的方法?是的,已解决!感谢Irfan提到setVar函数。他的解决方案不起作用,因为它创建了另一条记录,而不是将所需的变量放入$\u请求数组中的jform数组中。我的解决方案是重写jform变量。我将完成上面的代码以使其更好。在此阶段,编辑记录时会丢失文件变量。这是固定的。仔细检查xml和php代码。我添加了一个隐藏字段,以便在编辑表单的其他部分时保留原始文件名。选择新文件后,将替换它。还有更多的问题需要解决,但我希望这会对未来有很大帮助。Cheers@ChamingaD:testthis->JRequest::setVar('column','Test');如果这是可行的,还有一些命名problem@ChamingaD当前位置列名称是什么?让我们来看看
public function save($data){
$input = JFactory::getApplication()->input;
$files = $input->files->get('jform');
$fieldName = 'thumbnail';
$data['thumbnail'] = $files[$fieldName]['name'];
return parent::save($data);
}
