从自定义管理模块在Magento中无法进行文件上传

Question

I created a custom admin module in magento. The module has a form which on submitting posts to a controller which handles the file upload.

I am getting the following error on submitting the form:

a:5:{i:0;s:22:"File was not uploaded.";i:1;s:1030:"#0 C:\wamp\www\magento-PhpDevGuide-packt\app\code\local\Endosoft\Categoryupdate\controllers\Adminhtml\CategoryupdateController.php(11): Varien_File_Uploader->__construct('uploadcsv')

Here is the form:

<?php $url = Mage::helper("adminhtml")->getUrl('adminhtml/categoryupdate/formpost'); ?>
<h4>Upload Your CSV</h4>
<form action="<?php echo $url ?>" method="post" enctype="multipart/form-data">
    <p><input name="form_key" type="hidden" value="<?php echo Mage::getSingleton('core/session')->getFormKey() ?>" /></p>
    <p><input type="file" name="csvupload" /></p>
    <p><input type="submit" name="submit" value="Submit" /></p>
</form>

Here is the controller method:

public function formPostAction() {
  $uploader = new Varien_File_Uploader('uploadcsv');
  $uploader->setAllowedExtensions(array('json'));
  $uploader->setAllowRenameFiles(false);
  $uploader->setFilesDispersion(false);
  $path = Mage::getBaseDir('media');
  $fileName = $_FILES['uploadcsv']['name'];
  $uploader->save($path, $fileName);

  $this->loadLayout();
  $this->renderLayout();
}

I could not understand why the file is not uploaded.

Could someone please clarify what is going wrong?

Additional Info:

• Instead of using magento form container and form i am using my own form by calling a phtml file from the layout..

Answer 1

I see that your file input looks like this:

<input type="file" name="csvupload" />

Notice the name csvupload .
But in the formpostAction you are trying to read the uploadcsv field.
Make sure that what you submit matches what you process.
