本来想用插件上传图片的，后来自己写了一个简单的js实现异步的图片上传，不多说上代码非常简单
upload.php
if(isset($_FILES["myfile"]))
{
$ret = array();
$uploadDir = 'images'.DIRECTORY_SEPARATOR.date("Ymd").DIRECTORY_SEPARATOR;
$dir = dirname(__FILE__).DIRECTORY_SEPARATOR.$uploadDir;
file_exists($dir) (mkdir($dir,0777,true) && chmod($dir,0777));
if(!is_array($_FILES["myfile"]["name"])) //single file
{
$fileName = time().uniqid().'.'.pathinfo($_FILES["myfile"]["name"])['extension'];
move_uploaded_file($_FILES["myfile"]["tmp_name"],$dir.$fileName);
$ret['file'] = DIRECTORY_SEPARATOR.$uploadDir.$fileName;
}
echo json_encode($ret);
}
?>
index.html
