Call to undefined function fetch_phrase
 
I'm using a custom php script to create users in VBulletin 4.x. The scripts calls core VBulletin files, ex - require_once(CWD . '/includes/class_core.php');.

Unfortunately, when a username already exists, the script throws a fatal error:

Quote:
Fatal error: Call to undefined function fetch_phrase() in /home/xxxxx/public_html/members/includes/functions.php on line 4030
Line 4030 in the functions looks like this:

Code:
        // API only needs error phrase name and args.
        if (defined('VB_API') AND VB_API === true)
        {
                return $args;
        }

        $args[0] = fetch_phrase($args[0], 'error', '', false);  // line 4030
        if (sizeof($args) > 1)
        {
                return call_user_func_array('construct_phrase', $args);
        }
        else
        {
                return $args[0];
        }
Of course, the fetch_phrase function does exist, in /includes/functions_misc.php.

Within functions.php, the only time I see the fetch_phrase function get loaded is within the print_standard_redirect function

Code:
                        if (!function_exists('fetch_phrase'))
                        {
                                require_once(DIR . '/includes/functions_misc.php');
                        }
My take after looking around the functions.php file is that when an error occurs, there is an attempt to redirect ????

Given what I have shown, any idea on why I'm getting the "Call to ?" error message.

I'm using vBulletin 4.2.0 Patch Level 2.

Thanks.

Dave

It seems strange that someone else was getting that error on the same line, but I don't understand why a missing phrase would be the problem.

I have the code for version 4.2.0PL2, and I have this code at line 4008:
Code:
if (!function_exists('fetch_phrase') AND !VB_API)
{
        require_once(DIR . '/includes/functions_misc.php');
}
It seems to me that the only way that could not load is if your script was defining VB_API as something other than 'true' (or if fetch_phrase was already loaded, of course).

In any case, if it were me, I'd put in some debug statements. For example, I'd probably put a die() right before the require_once and see if it's getting there at all. Or maybe comment out the 'if' line and the closing } and so it's always included, and see if that fixes it. (Of course those changes are just temporary, you'd remove them after you see what happens).

You need to add this to your code:
PHP Code:
define('VB_API', false);

Yeah, that makes sense. That's done in init.php, but it could be that his script isn't including that.

Yes.
This will always return false: !VB_API, because VB_API is not defined.
It is defined in includes/init.php which is included in includes/class_bootstrap.php and this is included in global.php.
And because he is not including any of the above files, VB_API is not defined.

Oh right - I missed the first line where it said he was including class_core.php, and assumed he must be including global.php.

You're great! Works perfect. Thanks. Dave
