用钩子设置自定义页面标题

Question

I'm trying to set a custom page title (<title></title>) with wp_title.

The simplest function in the world:

function sweety_page_title($string)
{
    echo $string . ' - ';
}

After I call:

do_action('wp_title', 'my title...');
add_action('wp_title', 'sweety_page_title', 10, 1);

But it does not work.

Where am I wrong?

Answer 1

<?php add_filter( 'wp_title', 'filter_function_name', 10, 3 ) ?>

look at this http://codex.wordpress.org/Plugin_API/Filter_Reference there is all hooks check.

get the variable $var=add_filter( 'wp_title', 'filter_function_name', 10, 3 ); now call ur function, sweety_page_title($var)
