Joomla开发文件处理

Question

I'm making a simple MVC component for joomla following the hello world tutorial for the most part, with some some text fields and an image.

The text fields save but the "file" field does not, any ideas?

**Controller:**
    <?php
    // No direct access to this file
    defined('_JEXEC') or die('Restricted access');

    // import Joomla controllerform library
    jimport('joomla.application.component.controllerform');

    /**
     * MJob Controller
     */
    class MJobsControllerMJob extends JControllerForm
    {
    }

**Model:**

    <?php
    // No direct access to this file
    defined('_JEXEC') or die('Restricted access');

    // import Joomla modelform library
    jimport('joomla.application.component.modeladmin');

    class MJobsModelMJob extends JModelAdmin
    {
        public function getTable($type = 'MJob', $prefix = 'MJobsTable', $config = array()) 
        {
            return JTable::getInstance($type, $prefix, $config);
        }

        public function getForm($data = array(), $loadData = true) 
        {
            // Get the form.
            $form = $this->loadForm('com_mjobs.mjob', 'mjob', array('control' => 'jform', 'load_data' => $loadData));

            if (empty($form)) 
            {
                return false;
            }
            return $form;
        }

        protected function loadFormData() 
        {
            // Check the session for previously entered form data.
            $data = JFactory::getApplication()->getUserState('com_mjobs.edit.mjob.data', array());
            if (empty($data)) 
            {
                $data = $this->getItem();
            }
            return $data;
        }
    }

**view.html.php:**

    <?php
    // No direct access to this file
    defined('_JEXEC') or die('Restricted access');

    // import Joomla view library
    jimport('joomla.application.component.view');

    class MJobsViewMJob extends JView
    {

        public function display($tpl = null) 
        {
            // get the Data
            $form = $this->get('Form');
            $item = $this->get('Item');

            // Check for errors.
            if (count($errors = $this->get('Errors'))) 
            {
                JError::raiseError(500, implode('<br />', $errors));
                return false;
            }
            // Assign the Data
            $this->form = $form;
            $this->item = $item;

            // Set the toolbar
            $this->addToolBar();

            // Display the template
            parent::display($tpl);
        }

        protected function addToolBar() 
        {
            JRequest::setVar('hidemainmenu', true);
            $isNew = ($this->item->id == 0);
            JToolBarHelper::title($isNew ? JText::_('COM_MJOBS_MANAGER_MJOB_NEW') : JText::_('COM_MJOBS_MANAGER_MJOB_EDIT'));
            JToolBarHelper::apply('mjob.apply');
            JToolBarHelper::save('mjob.save');
            JToolBarHelper::save2new('mjob.save2new');
            JToolBarHelper::cancel('mjob.cancel', $isNew ? 'JTOOLBAR_CANCEL' : 'JTOOLBAR_CLOSE');
        }
    }

**VIEW (tmpl/edit.php):**
<?php
// No direct access
defined('_JEXEC') or die('Restricted access');
JHtml::_('behavior.tooltip');
echo "<b>MJOB EDIT START</b><br>";
?>
<form action="<?php echo JRoute::_('index.php?option=com_mjobs&layout=edit&id='.(int) $this->item->id); ?>"
      method="post" enctype="multipart/form-data" name="adminForm" id="mjob-form">
    <fieldset class="adminform">
        <legend><?php echo JText::_( 'COM_MJOBS_MJOB_DETAILS' ); ?></legend>
        <ul class="adminformlist">
            <?php foreach($this->form->getFieldset('details') as $field): ?>
                <li><?php echo $field->label;echo $field->input;?></li>
            <?php endforeach; ?>
        </ul>
    </fieldset>
    <div>
        <input type="hidden" name="task" value="mjob.edit" />
        <?php echo JHtml::_('form.token'); ?>
    </div>
</form>

I'm guessing you're using Joomla! 2.5 based on the code provided.

So to retrieve a file that's been uploaded you will need to do something like:

$jFileInput = new JInput($_FILES);
$theFile = $jFileInput->get('jform',array(),'array');


// If there is no uploaded file, we have a problem...
if (!is_array($theFile)) {
    JError::raiseWarning('', 'No file was selected.');
    return false;
}

// Build the paths for our file to move to the components 'upload' directory
$theFileName = $theFile['name']['tablefile'];
$tmp_src    = $theFile['tmp_name']['tablefile'];
$tmp_dest   = JPATH_COMPONENT_ADMINISTRATOR . '/uploads/' . $theFileName;
$this->dataFile = $theFileName;

// Move uploaded file
jimport('joomla.filesystem.file');
$uploaded = JFile::upload($tmp_src, $tmp_dest);
// $uploaded contains boolean indicating success or failure
// $tmp_dest will contain final location of file if successful.
