Use array from plugin in template as conditional

[tbworld]

In my own code, I fixed some small issues with the lexer, some minor issues with the parsers, and beefed up some error routines. Most of these issues were found due to us extending the templating system. The average user has probably never run into any of these issues, unless they have used the templating system extensively. vBulletin allows you to force a save on almost all errors, it gets around the few validation problems on the stock conditionals, curly, and tag definitions. That was a smart move on their part.

I am not posting the other fixes. I doubt most users will want to alter their source files or have a need for the patches. At this point only someone expanding the templater system would be interested and they are welcome to contact me.

This particular fix will assist the beginner templater as single errors were not being displayed correctly. This did impact you with the safe-function "in_array".

Replace function in "/includes/function.php" with the new function below. Sorry, this cannot be done via a plugin.

PHP Code:

function fetch_error_array($errors)
{
    $compiled_errors = array();

        // TBWORLD - vBulletin.org - 2014.10.05
        //   Resolves one of the template erroneous compile errors and restores (broken) single error messages.
        //   This bug exists vBulletin v4.2.0 and earlier  --> 4.2.3.beta2.

        if (!is_array($errors))
        {
            $compiled_errors[] = $errors;
            return $compiled_errors;
        }
        else
        {    
            foreach ($errors as $key => $value)
            {
                if (is_string($value))
                {
                    $compiled_errors[$key] = fetch_error($value);
                }
                else if (is_array($value))
                {
                    $compiled_errors[$key] = call_user_func_array('fetch_error', $value);
                }
            }
        }    
        return $compiled_errors;
    }
