Warning: Cannot modify header information – headers already sent by

  • Hello,

    when I try to redirect after login using this php-code:

    $current_user = wp_get_current_user();
    $current_product = $current_user->user_login;
    $home = home_url();
    $product_page =$home.’/product/’.$current_product.’/’;
    header($product_page);

    I’m getting this warning message:

    Warning: Cannot modify header information – headers already sent by (output started at /…/…/wp.content/themes/storefront/header.php:10) in /…/…/wp-content/themes/StorefrontChild/regel_popup.php on line 11.

    The header.php from my storefront theme is:

    <?php
    /**
    * The header for our theme.
    *
    * Displays all of the <head> section and everything up till <div id=”content”>
    *
    * @package storefront
    */
    ?><!doctype html>
    <html<?php language_attributes();?>>
    <head>
    <meta charset=”<?php bloginfo( ‘charset’ ); ?>”>
    <meta name=”viewport” content=”width=device-width, initial-scale=1, maximum-scale=1.0, user-scalable=no”>
    <link rel=”profile” href=”https://gmpg.org/xfn/11″&gt;
    <link rel=”pingback” href=”<?php bloginfo( ‘pingback_url’ ); ?>”>

    <?php wp_head(); ?>
    </head>

    <body <?php body_class(); ?>>

    <?php do_action( ‘storefront_before_site’ ); ?>

    <div id=”page” class=”hfeed site”>
    <?php do_action( ‘storefront_before_header’ ); ?>

    <header id=”masthead” class=”site-header” role=”banner” style=”<?php storefront_header_styles(); ?>”>
    <div class=”col-full”>

    <?php
    /**
    * Functions hooked into storefront_header action
    *
    * @hooked storefront_skip_links – 0
    * @hooked storefront_social_icons – 10

    * @hooked storefront_header_cart – 60
    * @hooked storefront_primary_navigation_wrapper_close – 68
    */
    do_action( ‘storefront_header’ ); ?>

    </div>
    </header><!– #masthead –>

    <?php
    /**
    * Functions hooked in to storefront_before_content
    *
    * @hooked storefront_header_widget_region – 10
    */
    do_action( ‘storefront_before_content’ ); ?>

    <div id=”content” class=”site-content” tabindex=”-1″>
    <div class=”col-full”>

    <?php
    /**
    * Functions hooked in to storefront_content_top
    *
    * @hooked woocommerce_breadcrumb – 10
    */
    do_action( ‘storefront_content_top’ );

    I searched with google and found many reasons that could cause the problem (white lines, spaces, echo, etc…). I’ve been trying to solve it for some hours now, but I can’t seem to find what the problem is in my case.

    Anyone?

    THanks in advance,

    David

  • Hi ,

    Where you have put the code for redirection. The error may be happened because you have echo or print something before the header($product_page); header. Also where the Location argument in the header.

    header('Location: https://www.example.com/');

    Also actually what is the exact requirement do you want userr to redirect to product page once logged in ?
