I'm developing a custom component for creating, editing and saving data of single records including images. I know that in admin/models/forms/record.xml there must be field name="image" type="file" accept="image/*" but how and where do I need to write the simple php-code for uploading images to specific folder, in which file and how? Where to write the code from example by the link https://docs.joomla.org/How_to_use_the_filesystem_package ?

EDITED: Now I added in my admin/com_mycom/controllers/record.php the code:

public function save($data = array(), $key = 'id') { $file = JRequest::getVar('image', null, 'files', 'array'); $filename = JFile::makeSafe($file['name']); $src = $file['tmp_name']; $dest = "media/com_mycom/img/".$filename; if (JFile::upload($src, $dest)) { //Redirect to a page of your choice } else { //Redirect and throw an error message } parent::save(); }

$data = array(), $key = 'id' I got from function allowEdit()

SOLVED BUT... So the problem was in the name of input. JRequest::getVar contains 'image' but input type="file" has name="jform[image]". I've found the code:

$jinput = JFactory::getApplication()->input; $files = $jinput->files->get('jform'); $file = $files['image'];

instead of

$file = JRequest::getVar('image', null, 'files', 'array');

and now the file is being uploaded but unfortunately its name is not being updated in the DB

Ok, I've added under if (JFile::upload($src, $dest)) { the code:

$thisID = JRequest::getVar('id'); $db = JFactory::getDbo(); $query = $db->getQuery(true); $fields = array($db->quoteName('image') . " = " . $db->quote($filename)); $conditions = array($db->quoteName('id') . " = " . $thisID); $query->update($db->quoteName('#__mycom'))->set($fields)->where($conditions); $db->setQuery($query); $db->execute($query);

but is there some simplest way to update filename in the DB ?

You should add it to your controller, probably controllers/record.php. Override save function.

public function save($key = NULL, $urlVar = NULL) { // Upload your image // Save item parent::save(); }

UPDATE

"Failed to move file" error

This came from wrong $dest value. Destination has to be full path.

Wrong: 

$dest = "media/com_mycom/img/".$filename;

Correct:

$dest = JPATH_SITE."/media/com_mycom/img/".$filename;

  • Thanks. Now I get the Warning: Failed to move file! All the needed folders have 0777 Commented Apr 14, 2015 at 8:19
  • Please update your question and add save function to it. Is /tmp folder also include in "all the needed foldser"? Usually this error gomes if /tmp folder is not writable. Go to System > System Information > Directory Permissions and recheck if all directories are writable. Commented Apr 14, 2015 at 8:25
  • Yes, tmp also has 0777 and all the directories on the Directory Permissions tab are writable Commented Apr 14, 2015 at 8:41
  • Does your form have attribute enctype="multipart/form-data"? If not, then files won't be uploaded. Commented Apr 14, 2015 at 8:43
  • Yes, it does and name of image file is being saved successfully in the DB but file doesn't move to the folder Commented Apr 14, 2015 at 8:43

I would suggest you to refer administrator part of com_media component. It has all file upload related functionality developed.

It also includes error handling and other checks related to file system.
