上传原理很简单就是利用表单的打开方式为iframe的id名,这样就可以在当前页面的iframe打来了,实现文件上传,再利用js返回上传结果。



无刷新上传文件














php代码

sleep(2);
$fileTypes = array('jpg','png','gif','bmp');
$result = null;
$uploadDir = './upfiles';
$maxSize = 1 * pow(2,20);
if ($_SERVER['REQUEST_METHOD'] == 'POST' && isset($_POST['sub'])) {
$myfile = $_FILES['myfile'];
$myfileType = substr($myfile['name'], strrpos($myfile['name'], ".") + 1);
if ($myfile['size'] > $maxSize) {
$result = 1;
} else if (!in_array($myfileType, $fileTypes)) {
$result = 2;
} elseif (is_uploaded_file($myfile['tmp_name'])) {
$toFile = $uploadDir . '/' . $myfile['name'];
if (@move_uploaded_file($myfile['tmp_name'], $toFile)) {
$result = 0;
} else {
$result = -1;
}
} else {
$result = 1;
}
}
?>
