If you want to check that something isn't empty use operator == .
Let's say you want to check your post['name'] to be empty, you can use CODE if (post['name'] !== "") In this case if condition will only return true if post['name'] !== "" Also you can use empty CODE if (!empty(post['name']) { Will return true if your post['name'] is everything but empty. To check your post['name'] even better, you can use regular expression CODE $pattern = '/[^a-z]/i'; if(preg_match($pattern, $string)>0) { returns true if there was some other character than letter |

I add one tips:
CODE if(preg_match("/^\s*$/",$string)) { die("Sorry, but all fileds must be filled !"); } This code can prevent any kind of blank, including spacing. |
