PHP - loading static class sends headers
I have a simple page in HTML/CSS/PHP that connects to MySQL DB.
"index.php" is loaded and "mainPage::showSectionLogin($_SESSION['login'])" shows logging form
<?php session_start(); ?>
<?php require_once 'clMainPage.php'; ?>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN">
<HTML>
<HEAD>
<?php mainPage::setSectionHEAD() ?>
<LINK rel="stylesheet" type="text/css" href="style.css">
</HEAD>
<BODY>
<DIV id="sidebar">
<?php mainPage::showSectionLogin($_SESSION['login']) ?>
<?php mainPage::showSidebarMenu($_SESSION['login']) ?>
</DIV>
<DIV id="mai开发者_高级运维n">
<?php mainPage::showActualNews(5) ?>
</DIV>
</BODY>
</HTML>
"login.php" is executed after the logging form was filled
<?php session_start(); ?>
<?php require_once 'clMainPage.php'; ?>
<?php
if($_SERVER["REQUEST_METHOD"] == "POST") {
$dblink = mainPage::openDBconn();
$result = mainPage::checkIfUserCanLogIn($dblink, $_POST['inpLogin'], $_POST['inpPassw']);
if (mysql_num_rows($result) == 1) {
$row = mysql_fetch_array($result);
mainPage::logUserIn($row['login'], $row['passw']);
}
else
{
die("error checking user: there is no such user in a database");
}
mainPage::closeDBconn($dblink);
header("refresh:1;url=index.php");
} ?>
I don't inderstand why, during logging in, "header("refresh:1;url=index.php");" (line:18) says that "require_once 'clMainPage.php';" in file "login.php" (line:2) sends headers. How is it possible that "require_once 'clMainPage.php';", that is a class declaratin containing only static functions, actually sends headers?
There is white space after your closing php tag on line 1, that's what sends the headers
<?php
session_start();
require_once 'clMainPage.php';
if($_SERVER["REQUEST_METHOD"] == "POST") {
Do you have any whitespace / output before / after your < ?php. This is often the cause.
What does 'clMainPage.php' contain?
