Stevux was on the right track. I followed his lead and found a nice way to restrict submission to admin and god users.
In submit.php around line 56 you'll find this important switch statement :
PHP Code:
switch ($phase) {
case 0:
do_submit0();
break;
case 1:
do_submit1();
break;
case 2:
do_submit2();
break;
case 3:
do_submit3();
break;
}
Restricting access to phase zero seemed to me to be the best way so I added the restriction code to the above statement. It works just as advertised and the resulting code is as follows :
PHP Code:
switch ($phase) {
case 0:
$canIhaveAccess = 0;
$canIhaveAccess = $canIhaveAccess + checklevel('god');
$canIhaveAccess = $canIhaveAccess + checklevel('admin');
if($canIhaveAccess == 1)
{
do_submit0();
}
else
{
echo 'Only admins and god can post. I you know who to ask you may request admin status so that you can post';
}
break;
case 1:
do_submit1();
break;
case 2:
do_submit2();
break;
case 3:
do_submit3();
break;
}
I am not sure that the core Pligg developers intended this previously clean switch statement to be hacked like that, but it works for me.
A further step would be to make this restriction code conditional and to make the condition a user-configurable parameter in /admin_config.php so that god can choose at which user level submissions are allowed. I am sure that many site operators would appreciate this feature.
