我的upload-dialog.js中设置对话框的代码：
function getDialog()
{
if (!dialog) {
dialog = new Ext.ux.UploadDialog.Dialog({
url: 'upload-dialog-request.php',
reset_on_hide: false,
allow_close_on_upload: true,
upload_autostart: false, //true,
post_var_name: 'upload',
title: '图片上传',
permitted_extensions:['JPG','jpg','jpeg','JPEG','GIF','gif']
//minWidth: 400,
//minHeight: 200,
//width: 400,
//height: 350
});
dialog.on('uploadsuccess', onUploadSuccess);
//dialog.on('beforefileuploadstart', onBeforeFileUploadStart);
}
return dialog;
}
upload-dialog-request.php的内容(来自这篇blog:http://zjnbshifox.iteye.com/blog/123399)：
$file = "";
$result = array();
$ext = strrchr($_FILES["file"]["name"],'.');
$file = "". date("YmdHis") . $ext;
if(move_uploaded_file($_FILES["file"]["tmp_name"],"uploadIDPic/" . $file)){
$result = array('success'=>true,data=>$file);
}else{
$result = array('success'=> false, 'error'=> '文件上传错误');
}
echo json_encode($result);
但是我上传总是失败，我发现upload-dialog-request.php中$ext的值总是为空，感觉这个php程序没有得到上传的文件名，不知道如何解决？ |
