Hi there.
I want to know what file type I'm uploading. In fact, I know what it is, it's an image/jpeg, but for some reason it's not coming up in my $_FILES array.
This is the output when I print_r(FILES)
Array ( [image] => Array ( [name] => Az 036_small.jpg [type] => [tmp_name] => [error] => 2 [size] => 0 ) )
As you can see, plainly from the name of the file, it's an image/jpeg, but can anyone tell me why the [type] element is empty?
Here is the code for my upload class if it helps:
<?php
class sw_Upload {
protected $_uploaded = array();
protected $_destination;
protected $_max = 51200;
protected $_messages = array();
protected $_permitted = array('image/gif',
'image/jpeg',
'image/pjpeg',
'image/png');
protected $_renamed = false;
public function __construct($path) {
if (!is_dir($path) || !is_writable($path)) {
throw new Exception("$path must be a valid, writable directory.");
}
$this->_destination = $path;
$this->_uploaded = $_FILES;
print_r($_FILES);
}
public function move() {
$field = current($this->_uploaded);
$OK = $this->checkError($field['name'], $field['error']);
if ($OK) {
echo '<br />'.$_FILES['image']['size'];
$sizeOK = $this->checkSize($field['name'], $field['size']);
$typeOK = $this->checkType($field['name'], $field['type']);
if ($sizeOK && $typeOK) {
$success = move_uploaded_file($field['tmp_name'], $this->_destination . $field['name']);
if ($success) {
$this->_messages[] = $field['name'] . ' uploaded successfully';
} else {
$this->_messages[] = 'Could not upload ' . $field['name'];
}
}
}
}
public function getMessages() {
return $this->_messages;
}
protected function checkError($filename, $error) {
switch ($error) {
case 0:
return true;
case 1:
case 2:
$this->_messages[] = "$filename exceeds maximum size: " . $this->getMaxSize();
return true;
case 3:
$this->_messages[] = "Error uploading $filename. Please try again.";
return false;
case 4:
$this->_messages[] = 'No file selected.';
return false;
default:
$this->_messages[] = "System error uploading $filename. Contact webmaster.";
return false;
}
}
public function getMaxSize() {
return number_format($this->_max/1024, 1) . 'kB';
}
protected function checkSize($filename, $size) {
if ($size == 0) {
return false;
} elseif ($size > $this->_max) {
$this->_messages[] = "$filename exceeds maximum size: " . $this->getMaxSize();
return false;
} else {
return true;
}
}
protected function checkType($filename, $type) {
if (!in_array($type, $this->_permitted)) {
$this->_messages[] = "$filename is not a permitted type of file.";
return false;
} else {
return true;
}
}
