joomla 2.5：ajax登录，检查用户名和密码是否正确

Question

Im developing a AJAX login form for joomla 2.5 . It's all working fine, last thing I need to achieve is the password checking. The password is being received with this piece of code:

$password = $_POST['password'];

in the database the password looks like this

0c7aca777a2fec9c962a0e3938b8cb0f:7Zv9CyiSiIzFYDS7RtqrzsxuenjmmOgi

and this is the query (dont mind the safety for now)

$mysqli->query("SELECT username FROM q4jli_users WHERE username='$username' AND password='$password'"); 

the second part of the hashed password is a random salt, so I think this cannot be checked, maybe I should only check the first part of the hashed password.

Any ideas? Assistance is much appreciated

Checkout the Joomla API Docs . If you don't find what you need there, take a look at the default joomla authenticatin plugin at plugins\\authentication\\joomla\\joomla.php , some of the other authentication plugins that are installed with Joomla.

And finally, this question: Custom PHP function to verify correct password in Joomla , might assist as well.
