Magento : Admin Form Input Type “file” Value not Working

Question

In magento admin edit form section, file attribute value is empty. my file buttons code is :-

$fieldset->addField('actionc', 'file', array(
            'label'     => 'Upload',
            'name' =>'actionc',
            'disabled' => false,
            'readonly' => true,
            'tabindex' => 1


        ));

   $form->setValues($model->getData());
    $form->setUseContainer(true);
    $this->setForm($form);

How can I solve this problem.

Answer 1

IN your form.php file's _prepareForm() method add 'enctype' => 'multipart/form-data' in $form variable I think you miss that thing

$form = new Varien_Data_Form(array(
        'id' => 'edit_form',
        'action' => $this->getUrl(
            'adminhtml/updatestock/save',
            array(
                '_current' => true,
                'continue' => 0,
            )
        ),
        'method' => 'post',
        'enctype' => 'multipart/form-data'
    ));
    $form->setUseContainer(true);
    $this->setForm($form);

Edit update for Controller

// mychanges
$id = $this->getRequest()->getParam('id');
if($id){
    $objectModel->load($id);
    $imgName = $objectModel->getActionc();
}
// end my changes
$uploader = new Varien_File_Uploader('actionc'); 
$uploader->setAllowedExtensions(array('pdf'));
$uploader->setAllowRenameFiles(false); $uploader->setFilesDispersion(false); 
$path = Mage::getBaseDir('media') . DS . 'pdf' . DS; $imgName = time().$_FILES['actionc']['name']; 
$uploader->save($path, $imgName); 
$postData = $this->getRequest()->getPost(); 
$objectModel = Mage::getSingleton('ghrix_copymerge/merge'); 
$postData['actionc']=$imgName; 
$objectModel->setData($postData)->save();
