When i dpm that $vars, in classes key, there is no r_style class, whyyyy? I tried clear cache through devel module, but still the same, what i am doing wrong?

name = JH Template
core = 7.x
engine = phptemplate

styles[all][] = css/style.css
settings[bg_style] = 'r_style'


function jh_process_html(&$vars) {
    $vars['classes'] .= ' ' . theme_get_setting('bg_style');
    dpm($vars); // in classes string isn't r_style class

EDIT: the real question is, why theme_get_setting('bg_style') returns NULL

SOLVED: that jh_process_html function must be in template.php file, but i don't understand that drupal :D, because that function was executed even in if it was in theme-settings.php, but actually just sometimes and it causes some fails like that theme_get_setting returned null. I don't know why this happened, but it's really funny after so many years of development of drupal, this magic happened.

  • Why do you expect that to work? Where is the rest of your code?

Try this...

function jh_preprocess_html(&$vars) {
$vars['classes_array'][] = theme_get_setting('bg_style');

You need to do this at an earlier stage of the processing.

  • After dpm, i see in classes_array is one NULL item, that is because theme_get_setting('bg_style') gives me NULL. This is where the problem is.

  • Some sort of caching going on there probably...
