Proper use of continue;

[Lionel]

Why would the below display a blank page when using continue;?
I am trying to tell it to do nothing if it's a member, go ahead and open the script

<?php
chdir('/var/www/forums');
define('NO_REGISTER_GLOBALS', 1);
$phrasegroups = array();
$actiontemplates = array('lostpw' => array('lostpw'));
require_once('./global.php');
require_once('./includes/functions_login.php');
if ($bbuserinfo['userid'])
{
continue;
}
else
{
print_no_permission();
}
?>

PHP Code:

if (!$bbuserinfo['userid'])
{
print_no_permission();
} 


You don't need continue. In addition continue is for loop statements not if statement.

Thanks, but that gives me a blank page. As per the script writer it will work only with:

<?php
if (logon is set) then
do nothing / continue
else
redirect to logon page
end if
?>

so I cannot put ! in font of !$bbuserinfo['userid']

Just place

PHP Code:

if (!$bbuserinfo['userid'])
{
print_no_permission();
} 


Above your main script, and start coding.
Everything you code below that will be parsed for logged in users, and the guests will get the no permission page

wish that was easy. I am using one of those scripts that you absolutely cannot touched the php or it ceases to work. Everything is acomplished thru an external file. In there, I tell it to use the external logon file logon.php. And this is what I need to put in logon.php. Any other way it enters into a loop. That why the loop needs to be broken with continue;

BTW, if the condition of bbuserinfo is not met, it does ask you to login.
I was told that vbportal uses it, so it is possible
I also know that phpNuke uses it.
I am with vbadvanced and am very happy with it.

Again, the problem is the loop.

It might help if you'd post the script, or atleast the part which you are editing.

[Lionel]

the entire script is posted above (let's call it logon.php). So is the complete synthax to use as per author.

in the preferences file you simply put
#coreInclude logon.php

and logon.php posted above does it's thing.

PHP Code:

 <?php
chdir('/var/www/forums');
define('NO_REGISTER_GLOBALS', 1);
$phrasegroups = array();
$actiontemplates = array('lostpw' => array('lostpw'));
require_once('./global.php');
require_once('./includes/functions_login.php');
if ($bbuserinfo['userid'])
{
readfile('your_file');
}
else
{
print_no_permission();
}
?>

That should work.

[Lionel]

Nope, it does not. I get a blank page. I must use the continue clause as per author.

and the readfile clause (that you edited it to instead of require) makes it look ugly by displaying the raw html

If you MUST use a continue (i can really not think of any reason for this) then recode and use a case construct.
