Hi everybody,

I'm not wanting to use the default login page moodle, so I made a custom. The code is:


            <form class="loginform" name="login" method="post" action="/moodle/login/index.php">
               <p>Username :
                 <input size="10" name="username" />
               </p>
               <p>Password :
                 <input size="10" name="password" type="password" />
               </p>
               <p>
                 <input name="Submit" value="Login" type="submit" />
               </p>
            </form>  


My question is how i make for get e show a error the login os password for the user?

Hi


Moodle gives us this variable by GET in the url, 

?errorcode=n


        $errormsg = get_string("cookiesnotenabled");
        $errorcode = 1;
        $errormsg = get_string('username').': '.get_string("invalidusername");
        $errorcode = 2;
        $errormsg = get_string("invalidlogin");
        $errorcode = 3;
        $errormsg = get_string('sessionerroruser', 'error');
        $errorcode = 4;

Do not forget to activate the $CFG->alternateloginurl

Thank you Paco, 


I used the following code to display a wrong username password message on my custom login page. 


<?php 

if ($_GET["errorcode"] == 3){

   echo '<div class="error_msg">The Username and/or Password entered is invalid, please try again.</div></br>';

}

?>

In Moodle code, you should never access $_GET or $_POST directly. Always use optional_param or required_param instead, with an appropriate PARAM_... type. It does not really matter here, but you should get into good habits. That way you won't start accidentally write in-secure code in future. So, this should be:

if (optional_param('errorcode', 0, PARAM_INT) == 3) {
   echo '<div class="error_msg">The Username and/or Password entered is invalid, please try again.</div></br>';
}

That is a good point, I was going that route, but I couldn't figure out the code to do it that way.  Thank you for the code Tim.

I tried to implement the code from Tim into my custom login page. But it didn't do anything. Am I missing something? 
Thanks.

Hello, I tried both of your solutions on my login.php and index php (I just recently came to administer this Moodle site), and none of them work.
Ex 1:
if (optional_param('errorcode', 0, PARAM_INT) == 3) {
   echo '<div class="error_msg">The Username and/or Password entered is invalid, please try again.</div></br>';
}
Ex 2:
if ($_GET["errorcode"] == 3){
   echo '<div class="error_msg">The Username and/or Password entered is invalid, please try again.</div></br>';
}
Ex 3:
if ($errorcode == 3) {
   echo '<div class="error_msg">The Username and/or Password entered is invalid, please try again.</div></br>';
}
However, none of them works
I think I'm doing something wrong because I'm not using any customized auth php script, and it should reference the default login process. Even more, I found there and in the moodle.php the appropriate reference to the message it should display in the event of an error. So, what is that I'm missing?

Hi Robin
I had the same problem today on my Moodle 2.7 localhost dev site. A student could log in, but as admin I could not log in. I have a custom login page as well.
My fix was to go to mdl_user and reset the admin password. In my case I simply changed it to password (5f4dcc3b5aa765d61d8327deb882cf99) and it worked.

May I know how to activate the $CFG.

Include Moodle's config.php file in the login page file. That will activate $CFG
