Question

I’m developing a module with both a frontend and a backend. Until now everything has been ok, but now I want to upload images in the backend. I don’t know how to start, and everything I’ve tried has just given me a headache.

Thanks

After a few days of research, here is an easy to use example of how you can upload files in magento
How to create an image or video uploader for the Magento Admin Panel

Bassically, we need to add the 'enctype' => 'multipart/form-data' to our form

$form = new Varien_Data_Form(array(
        'id' => 'edit_form',
        'action' => $this->getUrl('*/*/save'),
        'method' => 'post',
        'enctype' => 'multipart/form-data'
    )
);

Add a field of type file to our fieldset

$fieldset->addField('fileinputname', 'file', array(
    'label'     => 'File label',
    'required'  => false,
    'name'      => 'fileinputname',
));

And save it in our controller

if(isset($_FILES['fileinputname']['name']) and (file_exists($_FILES['fileinputname']['tmp_name']))) {
  try {
    $uploader = new Varien_File_Uploader('fileinputname');
    $uploader->setAllowedExtensions(array('jpg','jpeg','gif','png'));

    $uploader->setAllowRenameFiles(false);

    $path = Mage::getBaseDir('media') . DS ;

    $uploader->save($path, $_FILES['fileinputname']['name']);

    $data['fileinputname'] = $_FILES['fileinputname']['name'];
  }catch(Exception $e) {

  }
}
