waterssaz Posted January 30, 2009 Share Posted January 30, 2009 Should do the trick: $ip = array(); $ip[] = '10.10.3.*'; $ip[] = '211.109.238.74'; $ip[] = '254.254.254.2'; function testIP($ip){ //testing that correct IP address used in order //to access admin area... for($i=0, $cnt=count($ip); $i<$cnt; $i++) { $ipregex = preg_replace("/./", "\.", $ip[$i]); $ipregex = preg_replace("/*/", ".*", $ipregex); if(preg_match('/'.$ipregex.'/', $_SERVER[REMOTE_ADDR])) return true; } return false; } Quote Link to comment Share on other sites More sharing options...
waterssaz Posted January 30, 2009 Share Posted January 30, 2009 Sorry think I have made a small syntax error in above: missed out a slash. use this instead for preg_replace $ipregex = preg_replace(”/\./”, “\.”, $ip[$i]); $ipregex = preg_replace(”/\*/”, “.*”, $ipregex); Quote Link to comment Share on other sites More sharing options...
HSKrustofsky Posted January 30, 2009 Author Share Posted January 30, 2009 First of all, thanks for your help. I am still having difficulties. It seems to be taking me into a blank page instead of the needed page, or error page(if IP doesn't match). Quote Link to comment Share on other sites More sharing options...
waterssaz Posted January 30, 2009 Share Posted January 30, 2009 do you have error reporting turned on? Quote Link to comment Share on other sites More sharing options...
printf Posted January 30, 2009 Share Posted January 30, 2009 Also add ^ in the beginning of the preg_match pattern, so you only block who you really want to block. Quote Link to comment Share on other sites More sharing options...
HSKrustofsky Posted January 30, 2009 Author Share Posted January 30, 2009 I can't seem to find the error reporting. My custome has decided to host with Yahoo, and I don't know if they have, or offer that. Also, printf, where would I add the ^ in the preg_match pattern. I know you said at the beginning, but exactly where? Just right after the quotes? Quote Link to comment Share on other sites More sharing options...
printf Posted January 30, 2009 Share Posted January 30, 2009 Sorry, I should have explained it better... change this... if(preg_match('/'.$ipregex.'/', $_SERVER[REMOTE_ADDR])) to this... if(preg_match('/^'.$ipregex.'/', $_SERVER[REMOTE_ADDR])) Quote Link to comment Share on other sites More sharing options...
HSKrustofsky Posted January 31, 2009 Author Share Posted January 31, 2009 Once again thank you for your help, but I am still getting a blank page. I have no idea what's going on. Any suggestions? Quote Link to comment Share on other sites More sharing options...
premiso Posted January 31, 2009 Share Posted January 31, 2009 To see the error do this: <?php error_reporting(E_ALL); ini_set("display_errors", 1); $userip = array("123.456.789.10","10.123.456.*"); if (in_array($_SERVER['REMOTE_ADDR'], $userip)) { ?> Report back what it says.

HSKrustofsky Posted February 1, 2009 Author Share Posted February 1, 2009 Finally, I have found something that works... well, sort of. I have it to where it's allowing the IP address, but not the IP ranges. Is there a way of somehow doing the opposite of preg_match, or something? Here is the code I am working with... <?php $ip_list = array('123.456.789.10', '10.789.456.789'); $ip_range = array('10.123.456.*', '10.456.789.*'); $user_ip = $_SERVER['REMOTE_ADDR']; if(!in_array($user_ip, $ip_list)) { header("Location:http://".$_SERVER['HTTP_HOST']."/error.html"); } if(!empty($ip_range)) { foreach($ip_range as $range) { $range = str_replace('*','(.*)', $range); if(preg_match('/'.$range.'/', $user_ip)) { header("Location:http://".$_SERVER['HTTP_HOST']."/error.html"); } } } ?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html;
