Télécharger un fichier dans joomla en utilisant un module

Question

J'essaye de créer un module spécifique pour télécharger des fichiers.

J'utilise ce code:

côté client:

<?php 
// No direct access 
defined('_JEXEC') or die; $resposta =""; ?> 
<form name="upload" method="post" enctype="multipart/form-data"> 
<input type="file" name="file_upload" /> 
<input type="submit" name="submit_file" value="submit_file"/> 
<input type="text" name="resposta" value=<?php echo $resposta; ?> /> 
</form> 

Mon Module:

<?php 
    defined('_JEXEC') or die; 

include_once __DIR__ . '/helper.php'; 

//trigger the event 


// Instantiate global document object 
defined('_JEXEC') or die; 

    // Include the syndicate functions only once 
    require_once dirname(__FILE__) . '/helper.php'; 

    $resposta = ModuploadfileHelper::getuploadfile($params); 
    require JModuleHelper::getLayoutPath('mod_upload_file'); 


?> 

Mon aide:

<?php 


    class ModuploadfileHelper { 


     public static function getuploadfile($params) { 
     /* 
      * File upload example 
            */ 
     //Retrieve file details from uploaded file, sent from upload form 
     $file = JFactory::getApplication()->input->get('file_upload'); 

     //Import filesystem libraries. Perhaps not necessary, but does not hurt 
     jimport('joomla.filesystem.file'); 

     //Clean up filename to get rid of strange characters like spaces etc 
     $filename = JFile::makeSafe($file['name']); 

     //Set up the source and destination of the file 
     $src = $file['tmp_name']; 
     $dest = JPATH_COMPONENT . DS . "uploads" . DS . $filename; 
     if(!JFolder::exists($dest)) 
     { 
      $mode = 0755; 
      JFolder::create($dest, $mode); 
     } 
     $resposta = null; 
     //First check if the file has the right extension, we need jpg only 
     if (strtolower(JFile::getExt($filename)) == 'jpg') 
     { 
     // TODO: Add security checks 

      if (JFile::upload($src, $dest)) 
      { 
       $resposta = "Sucesso ao arquivar a imagem"; 
      }  
      else 
      { 
       $resposta = "Insucesso ao arquivar a imagem"; 
      } 
     } 
     else 
     { 
      $resposta = "O ficheiro não é uma imagem"; 
     } 
     return $resposta; 
     } 
    } 

?> 

Première question: Est-ce que quelque chose comme ce travail? Deuxième question: Comment effectuer un déclenchement pour que le module fonctionne? Treizième question: Comment passer le module à l'ajax?

J'ai quelque chose comme ceci:

Code du module:

<?php 
    defined('_JEXEC') or die; 

include_once __DIR__ . '/helper.php'; 

// Instantiate global document object 
defined('_JEXEC') or die; 

    // Include the syndicate functions only once 
    require_once dirname(__FILE__) . '/helper.php'; 

    $resposta = ModuploadfileHelper::getuploadfile($params); 


defined('_JEXEC') or die; 

include_once __DIR__ . '/helper.php'; 

// Instantiate global document object 
$doc = JFactory::getDocument(); 

$js = <<<JS 
(function ($) { 
    $(document).on('click', 'input[type=submit]', function() { 
      formdata = new FormData(); 
      var file = this.files[0]; 
      formdata.append("image", file); 

     $.ajax({ 
      type : 'POST', 
      data : request, 
      success: function (response) { 
       $('.search-results').html(response); 
      } 
     }); 
     return false; 
    }); 
})(jQuery) 
JS; 


$doc->addScriptDeclaration($js); 
require JModuleHelper::getLayoutPath('mod_upload_file'); 

?> 

Aidez-moi s'il vous plaît.

Il est possible, ce que vous devez faire, est d'utiliser l'interface Joomla ajax.

Voir la documentation ici: https://docs.joomla.org/Using_Joomla_Ajax_Interface

Il y a un exemple complet d'un module implantant ce, que vous pouvez modifier facilement adapter à télécharger le fichier: https://github.com/Joomla-Ajax-Interface/Ajax-Session-Module
