File upload Joomla 3.3 MVC文件/pdf在自定义组件后端上传

我想在编辑模式下从后端的自定义组件上载pdf。 国家现在是,， 1.-pdf上传正确，但数据库中未写入文件名， 2.-或者文件名写在数据库中，但JFactory:：getApplication（）->input看不到pdf

我发现是用enctype=“multipart/form data”做的。 在案例1中，-enctype=“multipart/form data”在中，并上载pdf 案例2。-pdf文件名写入数据库。 你知道什么？当然，我两者都需要

这里有这么多代码，这是Joomla下的一个具有MVC结构的小组件com_作业！3.3：

这里只有部分文件administrator/components/com_job/views/tmpl/edit.php 使用enctype=“多部分/表单数据”

错误在哪里？我试图将enctype=“multipart/form data”放入job.xml（models）中的表单中，但没有成功

我找到了一个临时解决方案，在控制器的save函数中，我添加了以下代码：

            //$jform = $jinput->get(jform, null);
            $pdf_filename = JFile::makeSafe($files['upload_pdf']['name']);
            $jform = $_POST['jform'];
            $tmp_pdf_filename = array('upload_pdf' => $pdf_filename);
            $merged_jform = array_merge($jform,$tmp_pdf_filename);
            $jinput->post->set('jform',$merged_jform);

第一行有$jinput的代码不起作用。我用$jinput尝试了很多方法，但都不管用。所以最后我直接使用了$u POST。当然，这不是正确的方法，但至少是可行的

这里是完整的功能保存：

    public function save()
{
    $jinput = JFactory::getApplication()->input;
    $files = $jinput->files->get('jform', null);

    $pdf_filename = JFile::makeSafe($files['upload_pdf']['name']);

    if (!empty($pdf_filename)) {

        $pdf_path = JPATH_ROOT . '/images/upload_pdf';
        if (!JFolder::exists($pdf_path)) {
            $status = JFolder::create($pdf_path);
            if (!$status) {
                JError::raiseWarning(100, JText::_('could not create directory pdf'), '');
            }
        }
        $file_path = JPath::clean($pdf_path . '/' . strtolower($files['upload_pdf']['name']));

        $status = JFile::upload($files['upload_pdf']['tmp_name'], $file_path);
        if ($status) {
            //$jform = $jinput->get(jform, null);
            $jform = $_POST['jform'];
            $tmp_pdf_filename = array('upload_pdf' => $pdf_filename);
            $merged_jform = array_merge($jform,$tmp_pdf_filename);
            $jinput->post->set('jform',$merged_jform);
        } else {
            JError::raiseWarning(100, JText::_('could not copy pdf'), '');
        }
    }
    return parent::save();
}

试试这个…这是真正的方法

这应该能奏效。$file数组然后保存以下键：

error
name
size
tmp_name
type
