function cf_theme_safe_css_string_part in Common Functionality 7.2

Same name and namespace in other branches

1. 7 modules/cf_theme/cf_theme.module \cf_theme_safe_css_string_part()

Returns a string with all non-word characters turned into underscores.

Justification: Drupals core css cleanup code does not properly handle all allowed css, namely underscores. This is a quick-way to ensure that all non-word characters are removed from a string to be used in css. This function is intended to be used to only create part of a string as done throughout the cf_theme_* functions to generate css names, such as: at-www_drupal_org.

Parameters

string $string: The string to cleanup.

Return value

string|false A string with all non-word characters turned into underscores. FALSE is returned if the preg_replace() functions returns something other than a string.
