To have the 'Remember Me' checkbox automatically checked for the users of your messageboards, you can change the following code in the files listed below.
(PLEASE NOTE: As with any time you are making changes to files, you should make a back up copy of the affected files before you make any changes)
You will need to change the code in the /includes/common.php and /login.php files as follows:
1.)In the /includes/common.php file, change the line:
$ltemplate->setTemplat eVar("REMEMBER_OPTION",$t his->createCheckBox("r emember_me",1,"",3) . " {$lang_str['R_ME']}");
to:
$ltemplate->setTemplat eVar("REMEMBER_OPTION",$t his->createCheckBox("r emember_me",1,1,3) . " {$lang_str['R_ME']}");
2.)In the /login.php file, change the line:
$template->setTemplate Var("REMEMBER_OPTION",$ht ml->createCheckBox("re member_me",1,"",3) . " {$lang_str['R_ME']}");
to
$template->setTemplate Var("REMEMBER_OPTION",$ht ml->createCheckBox("re member_me",1,1,3) . " {$lang_str['R_ME']}");
This will cause the 'Remember Me' checkbox in the users pop-up login to be preselected as well as making the appropriate change in the login.php file behind the scenes.
