如何在数据库中保存上传文件的名称

问题描述

继续.- 将文件上传器添加到 Joomla 管理组件>

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 扩展 JControllerForm{函数保存(){$file = JRequest::getVar('jform', null, 'files', 'array');$path = JPATH_BASE;//确保文件名安全.jimport('joomla.filesystem.file');$file['name']['invoice'] = JFile::makeSafe($file['name']['invoice']);//将上传的文件移动到一个永久位置.if (isset($file['name']['invoice'])) {//确保完整的文件路径是安全的.$filepath = JPath::clean($path.DS."components".DS."com_invoicemanager".DS."files".DS.strtolower($file['name']['invoice']));//移动上传的文件.JFile::upload( $file['tmp_name']['invoice'], $filepath );}返回父级::保存();}}

XML 中的表单字段 -

更新:添加以下来自@Andras Gera 代码的行后工作

$data = JRequest::getVar('jform', null, 'post', 'array');$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

<选项value="1">JPUBLISHED</option><选项value="0">JUNPUBLISHED</option></field><字段类型=文件"名称="pdf_file"标签="COM_GONEWSLETTER_EDIT_FILE_LABEL"默认="描述="COM_GONEWSLETTER_EDIT_FILE_DESC"大小=40"接受=申请/pdf"类=文件上传器"/><字段名称=文件"类型=隐藏"/></fieldset></表单>

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

view_list = '列表';parent::__construct($config);}函数保存(){//--------------------- 上传文件 ---------------------//必要的库和变量jimport('joomla.filesystem.folder');jimport('joomla.filesystem.file');$data = JRequest::getVar('jform', null, 'post', 'array');//如果图像文件夹中不存在 gonewsleter 文件夹，则创建该文件夹if ( !JFolder::exists( JPATH_SITE . DS . "images" . DS . "gonewsletter" ) ) {JFolder::create( JPATH_SITE . DS . "images" . DS . "gonewsletter" );}//从请求中获取文件数据数组.$file = JRequest::getVar('jform', null, 'files', 'array');//确保文件名安全.$filename = JFile::makeSafe($file['name']['pdf_file']);//将上传的文件移动到一个永久位置.如果($文件名！= ''){//确保完整的文件路径是安全的.$filepath = JPath::clean( JPATH_SITE . DS . 'images' . DS . 'gonewsletter' . DS . strtolower( $filename ) );//移动上传的文件.JFile::upload( $file['tmp_name']['pdf_file'], $filepath );//在保存到数据库之前更改 $data['file'] 值$data['file'] = strtolower( $filename );}//--------------------- 文件上传结束 ------------------------JRequest::setVar('jform', $data );返回父级::保存();}}

如果您在将 $data 发送到 parent::save($data) 之前打印它，它包含您想要保存的正确字段，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:输入类型=文件和名称=pdf_file，然后我添加了一个隐藏字段名称=文件默认=".然后我将此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.

Cont. - Add File Uploader to Joomla Admin Component

I could able to upload file and save it on disk. But its not saving file name on the database.

How can i do it ?

Here is the controller -

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();
    }
}

Form field in XML -

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

UPDATE: worked after adding following lines taken from @Andras Gera code

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

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

I've ran into the same problem, maybe we can go forward together. Here is my codes:

/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"

            size="40"
            class="inputbox"
            required="true"
            default=""
        />
        <field
            name="date"
            type="calendar"

            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>

and /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();
    }

}

If you print out the $data before send it to parent::save($data) it contains the right fields you want to save, but it doesn't. I tried to use an input type=text instead of type=file and it saves correctly.

I tried another way like: input type=file and name=pdf_file, after then I added a hidden field name=file default="". And then I've set up this hidden field value to filename without success. Maybe I was doing something wrong. Keep continue to figure out something.
