I found by default, Joomla trimed out all html tag in request variables.
The solution is like that:
In 1.8.X, by the default, the frist blog will aggregate the posts from all other blogs. But new version 2.4.x, it won't do by default. I read some posts in forums. Some people suggested to use multiblogs.php and summary.php. Yes, they are right, if you want to do a custom layout, please use multiblogs.php, if you want to have a summary of your blogs, using summary.php is a right choice. But if you just want the frontpage working like the older version. Please go to backoffice->Blog setting. And select you default blog. At Advance tab, there is an option to set aggregate blogs' post. You need to enter ID of blogs need to be aggregated in a comma-separated format, such as "2,3,5". Then it will work for you.
I did an upgarde to b2evolution 2.4.6 this morning.
I can't login again.
It gave me this error:
Either you have not enabled cookies or this login window has expired.
I found the solutions;
Go to conf/_advanced.php
Actually, just need to change a unique name, then it will be fixed.
I have added the subscribe buttons of RSS for my wordpress blog.I tried Add to Any Subscribe Button and Subscribe Sidebar plugin. "Add to Any Subscribe Button" can add your rss feed to almost all feed readers , such as Google Reader, My Yahoo!, Netvibes and Windows Live. But it will lead the reader to their smart menu. That is not somethings I prefer. I prefer there was some button in my blog. The reader can directly add my feed to their rss reader directly. Subscribe sider can do that. But I don't know why after I added widget into my page. There is an extra h1 tag on the plugin.
But that is easy to fix.
Easy, Easy, Easy
In PHP, you have $_GET and $_POST. In Joomla 1.5 framework, that is easy and quite similar with ASP.Net.
JRequest, then you can access GET and POST.
