Joomla 3.3 MVC file/pdf upload in custom component backend - file-upload

Question

I want to upload a pdf from a custom component from backend in the edit mode.
the state now is,
1.- either the pdf is uploaded correctly but the file name is not written in the database,
2.- or the file name is written in the data base, but the pdf is not seen by JFactory::getApplication()->input;
I found out is has with enctype="multipart/form-data" to do.
In case 1.- enctype="multipart/form-data" is in and the pdf is uploaded
in case 2.- the pdf file name is written in the data base.
What to do know ? I need both, of course.
Here so code, it is a little component com_job with MVC structure under Joomla! 3.3:
here just the part file administrator/components/com_job/views/tmpl/edit.php
with the enctype="multipart/form-data"
<form method="post" action="<?php echo JRoute::_('index.php?option=com_job&layout=edit&id='.(int) $this->item->id); ?>" id="adminForm" name="adminForm" enctype="multipart/form-data">
<fieldset class="adminform">
<legend><?php echo JText::_( 'Details' ); ?></legend>
<div class="control-group">
<div class="control-label">
<?php echo $this->form->getLabel('title'); ?>
</div>
<div class="controls">
<?php echo $this->form->getInput('title'); ?>
</div>
</div>
....
<div class="control-group">
<div class="control-label">
<?php echo $this->form->getLabel('upload_pdf'); ?>
</div>
<div class="controls">
<?php echo $this->form->getInput('upload_pdf'); ?>
</div>
</div>
........
here a part of the xml file administrator/components/com_job/models/forms/job.xml
<?xml version="1.0" encoding="utf-8"?>
...
<field
id="title"
name="title"
type="text"
required="true"
label="Title"
description="title_Desc"
class="inputbox"
size="40"/>
<field
id="upload_pdf"
name="upload_pdf"
type="file"
required="false"
label="Upload_pdf"
description="upload_pdf_Desc"
class="inputbox"
size="40"
accept="application/pdf"/>
.....
here the controller administrator/components/com_job/controllers/job.php
jimport('joomla.application.component.controlleradmin');
jimport('joomla.application.component.controllerform');
jimport('joomla.filesystem.file');
jimport('joomla.filesystem.folder');
class JobControllerJob extends JControllerForm
{
public function save()
{
$jinput = JFactory::getApplication()->input;
$files = $jinput->files->get('jform', null);
$files['upload_pdf']['name'] = JFile::makeSafe($files['upload_pdf']['name']);
if (!empty($files['upload_pdf']['name'])) {
$pdf_path = JPATH_ROOT . '/images/upload_pdf';
if (!JFolder::exists($pdf_path)) {
$status = JFolder::create($pdf_path);
if (!$status) {
JError::raiseWarning(100, JText::_('could not create directory pdf'), '');
}
}
$file_path = JPath::clean($pdf_path . '/' . strtolower($files['upload_pdf']['name']));
$status = JFile::upload($files['upload_pdf']['tmp_name'], $file_path);
if (!$status) {
JError::raiseWarning(100, JText::_('could not copy pdf'), '');
}
}
return parent::save();
}
}
where is the error ? I tried to put enctype="multipart/form-data" in the form in job.xml (models), but it didn't work.
I found a temporally solution, in the save function in the controller, I add this code:
//$jform = $jinput->get(jform, null);
$pdf_filename = JFile::makeSafe($files['upload_pdf']['name']);
$jform = $_POST['jform'];
$tmp_pdf_filename = array('upload_pdf' => $pdf_filename);
$merged_jform = array_merge($jform,$tmp_pdf_filename);
$jinput->post->set('jform',$merged_jform);
the first line with $jinput didn't work. I tried many ways with $jinput, but nothing worked. So finally I used directly $_POST. Of course, it is not the right way, but at least it works.
here the full function save:
public function save()
{
$jinput = JFactory::getApplication()->input;
$files = $jinput->files->get('jform', null);
$pdf_filename = JFile::makeSafe($files['upload_pdf']['name']);
if (!empty($pdf_filename)) {
$pdf_path = JPATH_ROOT . '/images/upload_pdf';
if (!JFolder::exists($pdf_path)) {
$status = JFolder::create($pdf_path);
if (!$status) {
JError::raiseWarning(100, JText::_('could not create directory pdf'), '');
}
}
$file_path = JPath::clean($pdf_path . '/' . strtolower($files['upload_pdf']['name']));
$status = JFile::upload($files['upload_pdf']['tmp_name'], $file_path);
if ($status) {
//$jform = $jinput->get(jform, null);
$jform = $_POST['jform'];
$tmp_pdf_filename = array('upload_pdf' => $pdf_filename);
$merged_jform = array_merge($jform,$tmp_pdf_filename);
$jinput->post->set('jform',$merged_jform);
} else {
JError::raiseWarning(100, JText::_('could not copy pdf'), '');
}
}
return parent::save();
}

Answer 1

$jinput = JFactory::getApplication()->input;
$files = $jinput->files->get('jform');
$file = $files['upload_pdf'];
Try this...it is true method!!!
That should do the trick. The $file array then holds the following keys:
error
name
size
tmp_name
type
