上传Magento包时$ _FILES为空

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

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