$_FILES empty when uploading Magento package - php

Question

I am trying to install a Magento package, but I get No file was uploaded
Its coming from this code because $_FILES is an empty array in /downloader/Maged/Controller.php
/**
* Install uploaded package
*/
public function connectInstallPackageUploadAction()
{
if (!$_FILES) {
echo "No file was uploaded";
return;
}
if(empty($_FILES['file'])) {
echo "No file was uploaded";
return;
}
$info =& $_FILES['file'];
if(0 !== intval($info['error'])) {
echo "File upload problem";
return;
}
$target = $this->_mageDir . DS . "var/" . uniqid() . $info['name'];
$res = move_uploaded_file($info['tmp_name'], $target);
if(false === $res) {
echo "Error moving uploaded file";
return;
}
$this->model('connect', true)->installUploadedPackage($target);
#unlink($target);
}
It might be worth noting that product uploads work fine.
The only log output I get is
2014-07-03T18:44:15+00:00 ERR (3): Warning: array_key_exists() expects parameter 2 to be array, null given in /var/www/vhosts/example.com/httpdocs/app/code/core/Mage/Captcha/Model/Observer.php on line 166
exception.log was empty

Answer 1

Make sure that your var folder in magento installation is fully writable. 777 permission. All folders and files.

Answer 2

You can try uploading a small dummy file first to check if the error stays the same.
There is a file upload limit which might be reached.
File upload often fails due to upload_max_filesize or post_max_size being too small as mentioned in Common Pitfalls section of the PHP documentation.

Answer 3

Use firebug in firefox to check if your form does has enctype="multipart/form-data".

Answer 4

Check the user group it was created with,
To explain, recently I had some file saving issues. Turned out I had created the folder using the Root user for the server, and the CPanel user ( the one php was running under ) didn't have permission to write in folders owned by the Root account, even when setting the permissions to 777.
Just a thought.

Answer 5

First check if your installation is configured properly
see#http://php.net/manual/en/features.file-upload.common-pitfalls.php
Also, if you upload with PUT/xhr the file is on the input stream
$in = fopen('php://input','r');
see#http://php.net/manual/en/features.file-upload.put-method.php and https://stackoverflow.com/a/11771857/2645347,
this would explain the empty $FILES array, in case all else is ok and the upload works via xhr/PUT.

Answer 6

$_FILES is an associative array of items uploaded to the current script via the HTTP POST method. All uploaded files are stored in $HTTP_POST_FILES contains the same initial information, but is not a superglobal. So, ... be sure that method is POST
Always check that your form contains correct enctype:
<form ... enctype="multipart/form-data"> ... </form>
Sometimes happens that when someone upload multiples file, $_FILES return empty. This could happen when I select files that exceed some size. The problem can be in the POST_MAX_SIZE configuration.

On
app/code/core/mage/captcha/model/observer.php
change
public function checkUserLoginBackend($observer)
{
$formId = 'backend_login';
$captchaModel = Mage::helper('captcha')->getCaptcha($formId);
$loginParams = Mage::app()->getRequest()->getPost('login');
$login = array_key_exists('username', $loginParams) ? $loginParams['username'] : null;
if ($captchaModel->isRequired($login)) {
if (!$captchaModel->isCorrect($this->_getCaptchaString(Mage::app()->getRequest(), $formId))) {
$captchaModel->logAttempt($login);
Mage::throwException(Mage::helper('captcha')->__('Incorrect CAPTCHA.'));
}
}
$captchaModel->logAttempt($login);
return $this;
}
to
public function checkUserLoginBackend($observer)
{
$formId = 'backend_login';
$captchaModel = Mage::helper('captcha')->getCaptcha($formId);
$login = Mage::app()->getRequest()->getPost('username');
if ($captchaModel->isRequired($login)) {
if (!$captchaModel->isCorrect($this->_getCaptchaString(Mage::app()->getRequest(), $formId))) {
$captchaModel->logAttempt($login);
Mage::throwException(Mage::helper('captcha')->__('Incorrect CAPTCHA.'));
}
}
$captchaModel->logAttempt($login);
return $this;
}
Your issue is:
"Captcha Observer throws an error if login in RSS feed" issue #208
or if you wish you could only replace the variable $login to be like this:
$login = array_key_exists('username', array($loginParams)) ? $loginParams['username'] : null;
