問題描述

繼續.- 將文件上傳器添加到 Joomla 管理組件>

我可以上傳文件并將其保存在磁盤上.但它沒有在數據庫中保存文件名.

我該怎么做?

這是控制器 -

class InvoiceManagerControllerInvoiceManager 擴展 JControllerForm{函數保存(){$file = JRequest::getVar('jform', null, 'files', 'array');$path = JPATH_BASE;//確保文件名安全.jimport('joomla.filesystem.file');$file['name']['invoice'] = JFile::makeSafe($file['name']['invoice']);//將上傳的文件移動到一個永久位置.if (isset($file['name']['invoice'])) {//確保完整的文件路徑是安全的.$filepath = JPath::clean($path.DS."components".DS."com_invoicemanager".DS."files".DS.strtolower($file['name']['invoice']));//移動上傳的文件.JFile::upload( $file['tmp_name']['invoice'], $filepath );}返回父級::保存();}}

XML 中的表單字段 -

更新:添加以下來自@Andras Gera 代碼的行后工作

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

我也遇到了同樣的問題，也許我們可以一起前進.這是我的代碼:

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

<選項value="1">JPUBLISHED</option><選項value="0">JUNPUBLISHED</option></field><字段類型=文件"名稱="pdf_file"標簽="COM_GONEWSLETTER_EDIT_FILE_LABEL"默認="描述="COM_GONEWSLETTER_EDIT_FILE_DESC"大小=40"接受=申請/pdf"類=文件上傳器"/><字段名稱=文件"類型=隱藏"/></fieldset></表單>

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

view_list = '列表';parent::__construct($config);}函數保存(){//--------------------- 上傳文件 ---------------------//必要的庫和變量jimport('joomla.filesystem.folder');jimport('joomla.filesystem.file');$data = JRequest::getVar('jform', null, 'post', 'array');//如果圖像文件夾中不存在 gonewsleter 文件夾，則創建該文件夾if ( !JFolder::exists( JPATH_SITE . DS . "images" . DS . "gonewsletter" ) ) {JFolder::create( JPATH_SITE . DS . "images" . DS . "gonewsletter" );}//從請求中獲取文件數據數組.$file = JRequest::getVar('jform', null, 'files', 'array');//確保文件名安全.$filename = JFile::makeSafe($file['name']['pdf_file']);//將上傳的文件移動到一個永久位置.如果($文件名！= ''){//確保完整的文件路徑是安全的.$filepath = JPath::clean( JPATH_SITE . DS . 'images' . DS . 'gonewsletter' . DS . strtolower( $filename ) );//移動上傳的文件.JFile::upload( $file['tmp_name']['pdf_file'], $filepath );//在保存到數據庫之前更改 $data['file'] 值$data['file'] = strtolower( $filename );}//--------------------- 文件上傳結束 ------------------------JRequest::setVar('jform', $data );返回父級::保存();}}

如果您在將 $data 發送到 parent::save($data) 之前打印它，它包含您想要保存的正確字段，但它沒有.我嘗試使用輸入 type=text 而不是 type=file 并正確保存.

我嘗試了另一種方式，例如:輸入類型=文件和名稱=pdf_file，然后我添加了一個隱藏字段名稱=文件默認=".然后我將此隱藏字段值設置為文件名但沒有成功.也許我做錯了什么.繼續想辦法.

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="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.
