- how fix “headers sent” error in php 11 answers
i've built site on test server , i'm putting on new server host site. i'm using pdo connections , once prepared statement executes redirect homepage of website sites on different server i'm getting error
error
cannot modify header information - headers sent (output started @ /home1/mlayzell/public_html/alpha/cms/includes/my-db-functions.php:17)
the code self membership activation, user signs e-mails user confirmation e-mail click link , there account gets changed active. here code if please me figuring out appreciated, in advance!
my-db-function.php
<?php require("config.php"); function connect_to_db() { global $dbhost, $dbname, $dbuser, $dbpass, $db; try { $db = new pdo('mysql:host='.$dbhost.';dbname='.$dbname.'', $dbuser, $dbpass); $db->setattribute(pdo::attr_errmode, pdo::errmode_exception); } catch(pdoexception $error) { echo 'error: ' . $error->getmessage(); } } ?> php
if($_get['action']==0) { if(isset($_post['name'],$_post['email'],$_post['password'])) { $key = md5(rand(0,1000)); $date = date('y-m-d h:i:s'); $statement_user = $db->prepare("insert `app_users` ( `use_name`, `use_key`, `use_email`, `use_password`, `use_date`, `use_status`, `use_typ_id`) values (:use_name, :use_key, :use_email, :use_password, :use_date, :use_status, :use_type);"); $statement_user->execute(array(':use_name' => $_post['name'], ':use_key' => $key, ':use_email' => $_post['email'], ':use_password' => $_post['password'], ':use_date' => $date, ':use_status' => "0", ':use_type' => "0")); $to = $_post['email']; $subject = 'signup | verification'; $message = ' signing up! account has been created, can login following credentials after have activated account clicking link below. ------------------------ email: '.$email.' password: '.$password.' ------------------------ please click link activate account: http://theapplist.com/alpha/cms/users/handler-users.php?action=5&use_email='.$_post['email'].'&use_key='.$key.' '; $headers = 'from:noreply@mysite.com' . "\r\n"; mail($to, $subject, $message, $headers); header('location:../index.php?signup=success'); } else { echo "fail"; } }
since, using header('location:../index.php?signup=success');
after outputting data browser already, error always happen.
because, header() function or headers should sent, before pages starts render html tags, before of page's contents loaded browser.
so if need small hack around of problem include echo ob_start() @ top of document. before <html>
like this:
<?php echo ob_start(); ?> <html> <head></head> //and keep going
