wordpress add_filter problem

Question

Hi,

I am trying to write a simple plugin to wordpress but i have a problem. this is the plugin:

function replace_css_php($text){
   return str_replace(".css",".php",$text);
}

add_filter('bloginfo', 'replace_css_php', 1, 1);
add_filter('bloginfo_url', 'replace_css_php', 1, 2);

the problems is that other plugins (not my plugins), added text to the header after me. it means that only some of the text going through replace_css_php and not all of it.

(the function replace_css_php is just a simple example, not in real life)

any idea?

Thanks

Answer 1

You would want to change the execution order (priority) of your filter:

add_filter ( 'hook_name', 'your_filter', [priority], [accepted_args] );

The default is 10, and you're setting the priority of both to 1, so they're being over-ridden by everything else on the page with a lower priority. Set the priority value to something much higher and it should work.

Looks to me like you're trying to filter the stylesheet URL?

In which case, use the more appropriate filter stylesheet_uri;

function replace_css_php($uri)
{
    return str_replace('.css', '.php', $uri);
}
add_filter('stylesheet_uri', 'replace_css_php');
