如何在数据库中保存上传文件的名称

Question

续。 - Add File Uploader to Joomla Admin Component

我可以上传文件并将其保存在磁盘上。但它没有在数据库中保存文件名。

我该怎么做？

这是控制器 -

class InvoiceManagerControllerInvoiceManager extends JControllerForm
{
    function save(){
        $file = JRequest::getVar('jform', null, 'files', 'array');
        $path = JPATH_BASE;

        // Make the file name safe.
        jimport('joomla.filesystem.file');
        $file['name']['invoice'] = JFile::makeSafe($file['name']['invoice']);

        // Move the uploaded file into a permanent location.
        if (isset($file['name']['invoice'])) {
            // Make sure that the full file path is safe.
            $filepath = JPath::clean($path. DS ."components". DS ."com_invoicemanager". DS ."files". DS .strtolower($file['name']['invoice']));
            // Move the uploaded file.
            JFile::upload( $file['tmp_name']['invoice'], $filepath );
        }

        return parent::save();
    }
}

XML 中的表单字段 -

<field name="invoice" type="file"/>

更新： 添加从@Andras Gera 代码中获取的以下行后工作

$data = JRequest::getVar( 'jform', null, 'post', 'array' );
$data['invoice'] = strtolower( $file['name']['invoice'] );

JRequest::setVar('jform', $data );

我也遇到了同样的问题，也许我们可以一起前进。这是我的代码：

/administrator/components/com_comp_name/models/forms/edit.xml

<?xml version="1.0" encoding="utf-8"?>
<form addrulepath="/administrator/components/com_gonewsletter/models/rules">
    <fieldset name="details">
        <field
            name="id"
            type="hidden"
        />
        <field
            name="title"
            type="text"
            label="COM_GONEWSLETTER_EDIT_TITLE_LABEL"
            description="COM_GONEWSLETTER_EDIT_TITLE_DESC"
            size="40"
            class="inputbox"
            required="true"
            default=""
        />
        <field
            name="date"
            type="calendar"
            label="COM_GONEWSLETTER_EDIT_DATE_LABEL"
            description="COM_GONEWSLETTER_EDIT_DATE_DESC"
            size="40"
            class="inputbox"
            required="true"
            default=""
            format="%Y-%m-%d"
        />
        <field
            name="published"
            type="list"
            label="JSTATUS"
            description="COM_GONEWSLETTER_EDIT_PUBLISHED_DESC"
            class="inputbox"
            size="1"
            default="0">
            <option
                value="1">JPUBLISHED</option>
            <option
                value="0">JUNPUBLISHED</option>
        </field>
        <field
            type="file"
            name="pdf_file"
            label="COM_GONEWSLETTER_EDIT_FILE_LABEL"
            default=""
            description="COM_GONEWSLETTER_EDIT_FILE_DESC"
            size="40"
            accept="application/pdf"
            class="fileuploader"
        />
        <field
            name="file"
            type="hidden"
        />
    </fieldset>
</form>

和 /administrator/components/com_comp_name/controllers/edit.php

<?php
// No direct access to this file
defined('_JEXEC') or die('Restricted access');

// import Joomla controllerform library
jimport('joomla.application.component.controllerform');

/**
 * GoNewsletter Controller
 */
class GoNewsletterControllerEdit extends JControllerForm
{
    function __construct($config = array()) {
        $this->view_list = 'List';
        parent::__construct($config);
    }

    function save(){
        // ---------------------------- Uploading the file ---------------------
        // Neccesary libraries and variables
        jimport( 'joomla.filesystem.folder' );
        jimport('joomla.filesystem.file');
        $data = JRequest::getVar( 'jform', null, 'post', 'array' );

        // Create the gonewsleter folder if not exists in images folder
        if ( !JFolder::exists( JPATH_SITE . DS . "images" . DS . "gonewsletter" ) ) {
            JFolder::create( JPATH_SITE . DS . "images" . DS . "gonewsletter" );
        }

        // Get the file data array from the request.
        $file = JRequest::getVar( 'jform', null, 'files', 'array' );

        // Make the file name safe.
        $filename = JFile::makeSafe($file['name']['pdf_file']);

        // Move the uploaded file into a permanent location.
        if ( $filename != '' ) {
            // Make sure that the full file path is safe.
            $filepath = JPath::clean( JPATH_SITE . DS . 'images' . DS . 'gonewsletter' . DS . strtolower( $filename ) );

            // Move the uploaded file.
            JFile::upload( $file['tmp_name']['pdf_file'], $filepath );
            // Change $data['file'] value before save into the database 
            $data['file'] = strtolower( $filename );
        }
        // ---------------------------- File Upload Ends ------------------------

        JRequest::setVar('jform', $data );

        return parent::save();
    }

}

如果您在将 $data 发送到 parent::save($data) 之前打印出它，它包含您要保存的正确字段，但它没有。我尝试使用输入 type=text 而不是 type=file 并正确保存。

我尝试了另一种方式，例如：输入 type=file 和 name=pdf_file，然后我添加了一个隐藏字段 name=file default=""。然后我将这个隐藏字段值设置为文件名，但没有成功。也许我做错了什么。继续想办法。

可以使用phpmove_uploaded_file()函数

Answer 3

    //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

如果文件成功上传，则运行查询。

Answer 4

在请求变量中设置文件名，因为它现在是 $_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');
            $path = JPATH_BASE;

            // Make the file name safe.
            jimport('joomla.filesystem.file');
            $file['name']['invoice'] = JFile::makeSafe($file['name']['invoice']);

            // Move the uploaded file into a permanent location.
            if (isset($file['name']['invoice'])) {
                // Make sure that the full file path is safe.
                $filepath = JPath::clean($path. DS ."components". DS ."com_invoicemanager". DS ."files". DS .strtolower($file['name']['invoice']));
                // Move the uploaded file.
                JFile::upload( $file['tmp_name']['invoice'], $filepath );

                JRequest::setVar('jform[invoice]',$file['name']['invoice'] );
            }



            return parent::save();
        }

}

在 joomla 3.2.x 上，我必须重写模型类的保存功能才能将上传的文件名保存到 db，像这样

public function save($data){
  $input = JFactory::getApplication()->input;       
  $files = $input->files->get('jform');
  $fieldName = 'thumbnail';
  $data['thumbnail'] = $files[$fieldName]['name'];              
  return parent::save($data);
}
