问题
I am using Offiria (joomla based social networking script) and when I click on the link "Show All Comments" to see all posted comments under a link, I get the following error right above the first comments. The function works so all comments expand and I can see them all but the error sits there as well.
Strict Standards: Non-static method StreamComment::getCommentsHTML() should not be called statically, assuming $this from incompatible context in C:\Program Files\Ampps\www\offiria\components\com_stream\controllers\comment.php on line 31
Here is the line 31 in comment.php file:
public function showall()
{
$stream_id = JRequest::getVar('message_id');
$html = StreamComment::getCommentsHTML($stream_id);
header('Content-Type: text/html; charset=UTF-8');
echo $html;
exit;
}
I have tried disabling all error reporting options in my php.ini but the error keeps coming up. I have also tried changing the above code to "public static function showall()" but I get an error that Strict Standards: Non-static method StreamComment::getCommentsHTML() should not be called statically.
I would appreciate any help with this in advance.

回答1:
What's happened here is that this function has been called statically:
StreamComment::showall(); // Static Call
But it's defined as a non-static method, which means PHP is expecting it to be called like this:
$obj = new StreamComment();
$obj->showall(); // Dynamic Call
If this is the only place this method is called, or it's consistently called statically, you can fix this by redefining the method as static:
public static function showall() // Added the "static" keyword
{
// [..code..]
}
Hope this helps :) x
