Remove "left-sidebar" from body_class() list in one template only

Found it, apparently there’s no ‘easy’ way to edit the tags of a template, which is quite odd, in my opinion. I used code from this site, here’s the specific code for my issue:

add_filter('body_class', 'adjust_body_class', 20, 2);
function adjust_body_class($wp_classes, $extra_classes) { 

if( is_page_template('page.php') ) :
// Filter the body classes     

      foreach($wp_classes as $key => $value) {
      if ($value == 'left-sidebar') unset($wp_classes[$key]);
      }

endif;
}

This runs through the keys that are generated (and apparently can’t be edited before generation) and just unset it if it happens to be ‘left-sidebar’, thus allowing me to have two different sets of CSS for two different templates.

I want to do this as well. I used the code above and got this error:

Warning: join() [function.join]: Invalid arguments passed in /home/aardvark/public_html/ratest3.com/wp-includes/post-template.php on line 387
class=””>

When I ad this line (as shown in the tutorial you found) I no longer get the error…

// Add the extra classes back untouched
return array_merge($wp_classes, (array) $extra_classes );

BUT – the body class of left-sidebar is still being put into the site (and yes I made sure I was looking on a ‘page’).

I want to remove the body class .left-sidebar for the entire site… all possible template files.

I am working with a 2011 child theme https://ratest3.com/sample-page/

I was looking on a ‘page’

the reply above is talking about a specific page template with the file name ‘page.php’;

if you are targeting all (static) pages, try to use:

if( is_page() ) :

there is no wildcard for page templates, you would need to reference them all individually.

depending on what you understand under ‘template files’, possibly remove the conditional statement totally; however in this case you could just use the ‘one-cloumn’ theme option, and increase the width(?)

alchymyth… hmmmmm.

What would your opinion be if I was building the child theme with 1 constant side bar on the left and one side bar that would be optional per which ever template file they assigned to the page, on the right?

(thanks for your reply btw)

Came back to say.. I think just using the one-column would be easiest. ??

for that idea, check my other article: https://www.transformationpowertools.com/wordpress/page-template-sidebar-overwrite-theme-options-twenty-eleven

with that coding, you can create two page templates which will have the sidebar independant of the theme options (as long as one of the layout options with sidebar is ticked)
