Basic image upload in Joomla custom component

I am trying to add image upload function to my view where I am creating model. I tried many sample codes here but I can't get to full path to file. My code looks like this:

public function submit() {
    jimport ( 'joomla.filesystem.file' );
    // Check for request forgeries.
    JRequest::checkToken () or jexit ( JText::_ ( 'JINVALID_TOKEN' ) );

    // Initialise variables.
    $app = JFactory::getApplication ();
    $model = $this->getModel ( 'createaction' );

    // Get the data from the form POST
    $data = JRequest::getVar ( 'jform', array (), 'post', 'array' );

    echo $data['image'];   <-- here

    $createdItem = $model->createItem ( $data );
    if ($createdItem) {
        $redirect = JRoute::_ ( 'index.php?option=com_akcehned&view=actions', false );
        $this->setRedirect ( $redirect, "Akce byla vytvořena" );
    } else {
        echo "<h2>Omlouváme se, ale něco se stalo špatně</h2>";
    }

    return true;
}

Part of file input in xml:

    <field 
        name="image" 
        type="file" 
        description="COM_AKCEHNED_FORM_DESC_CREATEACTION_IMAGE" 
        label="COM_AKCEHNED_FORM_LBL_CREATEACTION_IMAGE" 
        size="10" 
        accept="image/*" />

Where I tried to echo file file input I get just name (image_name.jpg and so) but I need fullpath right? I saw examples with ['tmp_name'] but It's not working for me. I tried code like this:

$jinput = $app->input;
$files = $jinput->files->get('jform');
$file = $files['image'];
echo $file;
echo $file['tmp_name'];

But it's not working for me either. I just get empty values. Can someone give me working block of code where I get data from other inputs and fullpath to file for upload? It's for joomla 2.5, Thanks

Did you try DPAttachments, it takes only three lines of code to integrate attachment support into your component. 

if (JLoader::import('components.com_dpattachments.libraries.dpattachments.core', JPATH_ADMINISTRATOR)) {
    echo DPAttachmentsCore::render('com_demo.item', $object->id);
}

Drag and drop and copy paste from your clipboard (no need to save the file to your hard disk) is supported. Perhaps you want to give it a try. If not here is a link to the Github repo how the upload function is implemented: https://github.com/Digital-Peak/DPAttachments/blob/master/com_dpattachments/admin/models/attachment.php#L50

You need to make sure the the form tag contains enctype attribute and that it is set to "multipart/form-data" if your are going to upload files.

eg

<form action="" method="post" enctype="multipart/form-data">

Also see: What does enctype='multipart/form-data' mean?
