比较不同模板部件中的值

For certain reasons I have to add a bit of style (margin) to the footer of the page. It should only be applied when the content part of the page is a product archive.

I tried to create a variable in the archive-products.php file like this:

<?php global $template;

$template = 'prodarchive';

var_dump($template);?>

According to the var_dump the value is set. Next I tried to call it in my footer.php like this

<?php if ($template === 'prodarchive' ) {?>

and then the stuff it needs to do.

Some tests shows me that the footer.php file is not able to reproduce the value of $template. What is wrong?

    The easiest solution (as pointed out by @seemly) is to apply the body_class() function to the <body> tag: 

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

    This will apply a range useful classes that you can use for CSS, including one of the product archive pages.

    Another approach is to use is_post_type_archive('product'), which returns a boolean value.

    As to why your global variable isn't working in footer.php, I'm pretty sure get_footer() isn't passed all global variables when it's called.
