ZF-8890: Undefined index tmp_name when uploading files using Zend_File
There is a bug in the _prepareFiles call in /Zend/File/Transfer/Adapter/Http.php. We are using 1.10. See the error shown below.
Exception 'ErrorException' with message 'Notice: Undefined index: tmp_name' in [...]/Zend/File/Transfer/Adapter/Abstract.php:1269 Stack trace: #0 [...]/Zend/File/Transfer/Adapter/Abstract.php(1269): Init->errorToException(Array) #1 [...]/Zend/File/Transfer/Adapter/Http.php(452): Zend_File_Transfer_Adapter_Abstract->_detectMimeType() #2 [...]/Zend/File/Transfer/Adapter/Http.php(52): Zend_File_Transfer_Adapter_Http->_prepareFiles()
This occurs because of the order of the $_FILES keys. _prepareFiles() iterates through $_FILES's keys, setting a variable within the iteration which is passed to _detectMimeType(). tmp_name is the second key from $_FILES, but _detectMimeType() uses that index in the first iteration, thus throwing the notice. A *really* dirty fix would be to insert the following on line 441:
$this->_files[$form . '_' . $number . '_']['tmp_name'] = $content['tmp_name'][$number];
Looking at the _prepareFiles() method, it's probably best to rewrite it ;-)
