Can't access existing php cookie -


this question has answer here:

i'm developing website on localhost uses cookies. have function generates random, 25 character string stored in database , set referential cookie on user's browser.

i've searched internet , site, wasn't able find solution problem.

below overview of related code

 function generaterandomstring($length){     $string = "";     $possible = "012346789abcdefghijklmnopqrstuvwabcdefghijklmnopqrstuvw";     $maxlength = strlen($possible);     if($length > $maxlength){         $length = $maxlength;     }     $i = 0;      while($i < $length){          $char = substr($possible, mt_rand(0, $maxlength-1), 1);         if(!strstr($string, $char)){              $string .= $char;             $i++;         }     }     return $string; }  $ucookie = generaterandomstring(25);  setcookie('uhash', $ucookie, time()+60*60*24*30);  $stmt = $dbh->prepare('     update user      set u_usercookie = :cookie      u_userid = :id ');   $stmt->execute(array(     ':cookie' => $ucookie,     ':id' => $user_id ));

now when try echo($_cookie['uhash']); empty string.

the strange part when check chrome preferences, cookie exists

name:    uhash content:    134uhneprcmbngqeajhrsuijl domain: localhost path:   /~path/to/login send for:   kind of connection accessible script:   yes created:    wednesday, april 17, 2013 4:21:27 pm expires:    friday, may 17, 2013 4:21:27 pm

the string '134uhneprcmbngqeajhrsuijl' can found in database, works

am missing basic info cookies (on localhost)?

solved

the problem is, according php.net

'that domain names must contain @ least 2 dots (.), hence 'localhost' invalid , browser refuse set cookie'

so solved doing this

 $domain = ($_server['http_host'] != 'localhost') ? $_server['http_host'] : false; setcookie('uhash', $ucookie, time()+60*60*24*30, '/', $domain, false);

see issue: cookies on localhost explicit domain

domain names in cookie must contain 2 dots. localhost therefor invalid.

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers ...
