redirect not working

  • I know this is a fairly common problem and it is usually ascribed to white space. I have a template with a redirect and I am getting this error:

    Warning: Cannot modify header information – headers already sent by (output started at C:\xampp\htdocs\WP\wp-includes\general-template.php:2406) in C:\xampp\htdocs\WP\wp-content\themes\2014-child\form-template.php on line 46

    I really can’t see white space and cannot see what is wrong. line 2406 in the general-template.php file is thus:

    echo '<link rel="wlwmanifest" type="application/wlwmanifest+xml" href="',
		includes_url( 'wlwmanifest.xml' ), '" /> ', "\n";

    Line 46 in the form-template reads thus:

    header("Location:localhost/wp/success-page/");?>

    But I’m including the entire form-template in case the error is actually generated from something prior to line 46:

    <?php
/**
 * The template for displaying pages
 *
 * This is the template that displays all pages by default.
 * Please note that this is the WordPress construct of pages and that
 * other "pages" on your WordPress site will use a different template.
 *
 * @package WordPress
 * @subpackage Twenty_Fourteen
 * @since Twenty Fourteen 1.0
 *  Template Name: form-template.php
 */

get_header(); ?>

	<div id="primary" class="content-area">
		<main id="main" class="site-main" role="main">

			<?php // Include the page content template.
			get_template_part( 'content', 'page' ); ?>

<?php
$film_title = $_POST["title"];
$film_year = $_POST["year"];
$film_link = $_POST["link"];
$film_genre = $POST["genre"];
$film_decade = $POST["decade"];
$film_smpic = $POST["sm-pic"];

$servername = "localhost";
$username = "root";
$password = "********";

$conn =  mysqli_connect($servername, $username, $password);

if (!$conn) {
	die("Connection failed: ".mysqli_error());
}

// Data insertion into database
$query = "INSERT INTO 'movies'.'films' ( 'alpha-name', 'year', 'page-link', 'genre', 'decade','sm-pic' ) VALUES ( $film_title, $film_year, $film_link, $film_genre,$film_decade,$film_smpic)";
mysqli_query($conn, $query);

// Redirection to the success page
header("Location:localhost/wp/success-page/");?>

	</main><!-- .site-main -->
	</div><!-- .content-area -->

    I understand that there are probably other errors in this code that prevent it from being functional, but right now I’m just trying to solve this header error.

    The problem is that you cannot use header() once you have started outputting HTML. The following part of your code MUST be executed before you call the get_header() function:

    <?php
$film_title = $_POST["title"];
$film_year = $_POST["year"];
$film_link = $_POST["link"];
$film_genre = $POST["genre"];
$film_decade = $POST["decade"];
$film_smpic = $POST["sm-pic"];

$servername = "localhost";
$username = "root";
$password = "********";

$conn =  mysqli_connect($servername, $username, $password);

if (!$conn) {
	die("Connection failed: ".mysqli_error());
}

// Data insertion into database
$query = "INSERT INTO 'movies'.'films' ( 'alpha-name', 'year', 'page-link', 'genre', 'decade','sm-pic' ) VALUES ( $film_title, $film_year, $film_link, $film_genre,$film_decade,$film_smpic)";
mysqli_query($conn, $query);

// Redirection to the success page
header("Location:localhost/wp/success-page/");?>

    I will also add that your code will not work since you are not specifying a database in your call to mysqli_connect().
