Menu
I have the following code in header.php to echo the body's id: <body id="<?php echo $body; ?>"> which is taken from a variable from index.php: $body = "home";
The output result is: body id=""
Any suggestions to fix this?
(I made var_dump($body) and the value is "home" so the variable is working)
header.php:
<?php
/**
* The Header for our theme.
*
* Displays all of the <head> section and everything up till <div id="main">
*
* @package WordPress
* @subpackage Starkers
* @since Starkers 3.0
*/
?><!DOCTYPE html>
<html <?php language_attributes(); ?>>
<head>
<meta charset="<?php bloginfo( 'charset' ); ?>" />
<title><?php
/*

* We filter the output of wp_title() a bit -- see
* twentyten_filter_wp_title() in functions.php.

wp_title( '|', true, 'right' );
?></title>

wp_head();

Go to WordPress Installation directory. Follow the path wp-content > themes. Open your theme folder. In that you can see index.
To find the file and edit it yourself go to wp-content > themes > your-theme-name > header. php. You can then open it in a code editor and make any changes you need to.
The role of index PHP file in WordPress varies. When the index PHP file is in the root of the installation, it initializes the WordPress. On the contrary, in the Theme folder inside our theme index PHP file plays a different role. It achieves its goal, but in a different way.
You're dealing with a variable scoping issue.
Since the inclusion of the header.php is done by the get_header() function, the $body variable within the header.php file is contained within the scope of that function (i.e. it is a local variable in the function).
You need to declare the variable as global within the header.php file. Before doing anything else with the variable, add this line to header.php:
global $body;
I believe this should help achieve the behavior you're looking for.
