获取PHP注意：未定义索引：使用joomla以外的插件然后在joomla登录时在joomla中使用password_clear

Question

I am getting PHP Notice: Undefined index: password_clear when I use any plugin other then joomla's login plugin to log-in the user. In joomla database, we are not storing any user's data. so I have got a custom plugin, which will do the check for user's credentials through a web service call.

The credentials are checked good, and joomla does show the user has logged in, and rest of the things are also working fine. But my logs are filled with the above Notices!

Any one faced such problem or any hints or directions for me?

Thanks for help in advance, Tanmay

Answer 1

You can do two things:

1. Edit php.ini and set error_reporting to E_COMPILE_ERROR|E_RECOVERABLE_ERROR|E_ERROR|E_CORE_ERROR
2. Edit the plugin code and test the presence of password_clear before using it.

Here's an example how to do the testing part:

$clear = $_POST['password_clear']; /* old */
$clear = empty($_POST['password_clear']) ? '' : $_POST['password_clear']; /* fixed */

or:

if ($_POST['password_clear'] == 'x') {...} /* old */
if (! empty($_POST['password_clear']) && $_POST['password_clear'] == 'x') {...} /* fixed */

@JMZ, your reply did gave me some ideas of looking into the stuff, and I got the solution. I am not user, if the changes I did are valid, but it works for me. I basically grabbed the gmail.php login plugin as the base for creating my own plugin.

Now on the success I had to add $response->password_clear = ""; to the response object, so that at least it has a reference and will not give me a notice of undefined index.

Hope some one will be helped. Or if some one has a better understanding on this, please do let me know.
