如何在数据库上保存上载的文件名

Question

续 - 将文件上传器添加到Joomla Admin Component

我能够上传文件并将其保存在磁盘上.但它不保存数据库中的文件名.

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格式的表单字段 -

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

更新:在添加@Andras Gera代码中的以下行之后工作

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

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

我遇到了同样的问题,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();
    }

}

如果在将$ data发送到parent :: save($ data)之前将其打印出来,则它包含您要保存的正确字段,但它不包含.我尝试使用输入类型=文本而不是type = file并正确保存.

我尝试了另一种方式:input type = file和name = pdf_file,之后我添加了一个隐藏字段name = file default ="".然后我将这个隐藏的字段值设置为文件名而没有成功.也许我做错了什么.继续找出一些东西.
