Why PHP Error: Call to a member function set_prefix() on a non-object
- by Rebol Tutorial
I got this error
Fatal error: Call to a member function
set_prefix() on a non-object in
/home/reboltutorial/reboltutorial.com/wp-settings.php
on line 254
line 254 contains:
$prefix = $wpdb->set_prefix($table_prefix); // set up global tables
This occurs if I try to call index_wordpress() instead of calling these two lines
define('WP_USE_THEMES', true);
require('./wp-blog-header.php');
so this doesn't work:
<?php
function index_wordpress() {
define('WP_USE_THEMES', true);
require('./wp-blog-header.php');
}
?>
<?php
if(!function_exists('apache_request_headers')) {
function apache_request_headers() {
$headers = array();
foreach($_SERVER as $key => $value) {
if(substr($key, 0, 5) == 'HTTP_') {
$headers[str_replace(' ', '-', ucwords(str_replace('_', ' ', strtolower(substr($key, 5)))))] = $value;
}
}
return $headers;
}
}
function getCurrentPageUrl() {
$pageURL = 'http';
if ($_SERVER["HTTPS"] == "on") {$pageURL .= "s";}
$pageURL .= "://";
if ($_SERVER["SERVER_PORT"] != "80") {
$pageURL .= $_SERVER["SERVER_NAME"].":".$_SERVER["SERVER_PORT"].$_SERVER["REQUEST_URI"];
} else {
$pageURL .= $_SERVER["SERVER_NAME"].$_SERVER["REQUEST_URI"];
}
return $pageURL;
}
$a = apache_request_headers();
$pos = strrpos($a["User-Agent"], "REBOL");
if ($pos === false) {
index_wordpress();
} else {
if ($_SERVER['REMOTE_ADDR'] != "69.163.203.14") {
$command= './cgi-bin/index.cgi '. '"' . getCurrentPageUrl() . '"';
echo system($command);
} else {
index_wordpress();
}
}
?>
while this works:
<?php
if(!function_exists('apache_request_headers')) {
function apache_request_headers() {
$headers = array();
foreach($_SERVER as $key => $value) {
if(substr($key, 0, 5) == 'HTTP_') {
$headers[str_replace(' ', '-', ucwords(str_replace('_', ' ', strtolower(substr($key, 5)))))] = $value;
}
}
return $headers;
}
}
function getCurrentPageUrl() {
$pageURL = 'http';
if ($_SERVER["HTTPS"] == "on") {$pageURL .= "s";}
$pageURL .= "://";
if ($_SERVER["SERVER_PORT"] != "80") {
$pageURL .= $_SERVER["SERVER_NAME"].":".$_SERVER["SERVER_PORT"].$_SERVER["REQUEST_URI"];
} else {
$pageURL .= $_SERVER["SERVER_NAME"].$_SERVER["REQUEST_URI"];
}
return $pageURL;
}
$a = apache_request_headers();
$pos = strrpos($a["User-Agent"], "REBOL");
if ($pos === false) {
define('WP_USE_THEMES', true);
require('./wp-blog-header.php');
} else {
if ($_SERVER['REMOTE_ADDR'] != "69.163.203.14") {
$command= './cgi-bin/index.cgi '. '"' . getCurrentPageUrl() . '"';
echo system($command);
} else {
define('WP_USE_THEMES', true);
require('./wp-blog-header.php');
}
}
?>
