change bloginfo and customizing a stylesheet

<?php bloginfo('template_url') ?>/rtl.css

thank you.. I added your line in the header.php in the theme. and many elements became right. in the other hand there is not any effect of dir=”rtl” in the html tag !!

also I noted there are many css files with rtl suffix in the wp-admin. But I don’t know how to use them or how to let the design of the control panel take care of them .. any idea ??

If you want to actually change it:

Add the following code to your functions.php file.

add_filter(‘stylesheet_uri’, ‘change_css’);

function change_css() {
return “https://website.com/yourcssfile.css”;
}

WordPress loads the functions.php file prior to loading the template files. The add_filter we use here modifies stylesheet_uri, so when it gets called within your template, it will be the path you specified.

You can do this with most bloginfo variables.

View wp-includes/theme.php if you are curious what else can be modified, anything with “apply_filters(“whatever”)…..” can be modified, just replace whatever with what you’re modifying in your add_filter.

Good luck

Perhaps this is a better example:

add_filter(‘stylesheet_uri’, ‘change_css’);

function change_css() {
return get_bloginfo(‘template_url’) . ‘/my_custom_stylesheet_name.css’;

}
