Drupal 7: Reorder the css files - php

Question

I have included the following css files into my_theme.info file
stylesheets[all][] = style.css
stylesheets[all][] = css/all.css
stylesheets[all][] = css/static.css
and this files are loading on every page, but my particular css file associated with page is loading before the above css files.
But i want above css files should load first then my page css file load
what i do for that?

Answer 1

By default css files of theme (as set in mytheme.info file) are loading very last and after any other css files of any module. This is done to override any css if needed.
So, if you want to load the css files before any other you should better add them with drupal_add_css function in a custom module and set their weight as -100 or less (number is just an example of order weight).
To get the path you can use the current_path() or drupal_get_path_alias() (for the alias) or any other function/method to get the path.
But, as you said, these are theme css files so in your custom module you could also write this in your module:
function mymodule_init() {
// Set theme's path
$themepath = drupal_get_path('theme', 'mytheme');
// check current path
if (current_path() == "internal/path/of/the/page") {
// add theme css in group CSS_SYSTEM
drupal_add_css($themepath . '/path/to/mycss.css', array('group' => CSS_SYSTEM, 'type' => 'file', 'weight' => -100));
}
}
The code above will move the mycss.css file to group "CSS_SYSTEM" that loads the core css files first and before any other css files from modules (CSS_DEFAULT) or theme (CSS_THEME)
