Adding a file field to the manifest file - joomla

Question

My plugin requires a user to upload a file.
The manifest field doesn't set the form enctype="multipart/form-data" so when a file is uploaded it gets lost.
Is there a way to change this?

form xml :
<field name="con_image" type="file" label="" description="" hint="Image"/>
default.php
<div class="controls">
<?php if (!empty($this->item->con_image) && file_exists(JPATH_SITE.'/images/contact_image/thumb_' . $this->item->con_image)) : ?>
<img src="<?php echo JRoute::_(JUri::root() . 'images/contact_image/thumb_' . $this->item->con_image, false);?>">
<?php endif; ?>
<input type="hidden" name="jform[con_image]" id="jform_image_hidden" value="<?php echo $this->item->con_image; ?>" />
<?php echo $this->form->renderField('con_image'); ?>
</div>
your view table file code for image upload:
$files = $app->input->files->get('jform', array(), 'raw');
$array = $app->input->get('jform', array(), 'ARRAY');
if (!empty($files['con_image']['name']))
{
// Deleting existing files
$oldFiles = PlansHelpersPlans::getFiles($this->id, $this->_tbl, 'con_image');
foreach ($oldFiles as $f)
{
$oldFile = JPATH_ROOT . '/images/contact_image/' . $f;
if (file_exists($oldFile))
{
unlink($oldFile);
}
}
$this->con_image = "";
$singleFile = $files['con_image'];
jimport('joomla.filesystem.file');
// Check if the server found any error.
$fileError = $singleFile['error'];
$message = '';
if ($fileError > 0 && $fileError != 4)
{
switch ($fileError)
{
case 1:
$message = JText::_('File size exceeds allowed by the server');
break;
case 2:
$message = JText::_('File size exceeds allowed by the html form');
break;
case 3:
$message = JText::_('Partial upload error');
break;
}
if ($message != '')
{
$app->enqueueMessage($message, 'warning');
return false;
}
}
elseif ($fileError == 4)
{
if (isset($array['con_image']))
{
$this->con_image = $array['con_image'];
}
}
else
{
// Replace any special characters in the filename
jimport('joomla.filesystem.file');
$filename = JFile::stripExt($singleFile['name']);
$extension = JFile::getExt($singleFile['name']);
$filename = preg_replace("/[^A-Za-z0-9]/i", "-", $filename);
$filename = rand()."-".$filename . '.' . $extension;
$uploadPath = JPATH_ROOT . '/images/contact_image/' . $filename;
$fileTemp = $singleFile['tmp_name'];
if (!JFile::exists($uploadPath))
{
if (!JFile::upload($fileTemp, $uploadPath))
{
$app->enqueueMessage('Error moving file', 'warning');
return false;
}
}
//$this->con_image .= (!empty($this->con_image)) ? "," : "";
$this->con_image = $filename;
}
}else{
$this->con_image = $array['con_image'];
}
