add_filter the_content str_replace after shortcode

I want to add a PHP str_replace to the add_filter('the_content') function. I believe my problem is that the shortcodes are loading after the str_replace is called.

I have a shortcode that outputs a form, i want to make it that in all HTML form tags, the attribute autocomplete="off".

Heres the code i have.

add_filter('the_content', 'disable_autocomplete');
function disable_autocomplete( $content )
{
    return str_replace('<form', '<form autocomplete="off"', $content);
}

Any ideas?

You can change the priority of actions and filters, it’s the third argument of add_filter (and add_action) and it defaults to 10. So change it to a high number and have your filter fire way after the shortcodes and other stuff are inserted.

<?php 
add_filter('the_content', 'disable_autocomplete', 99);
function disable_autocomplete( $content )
{
    return str_replace('<form', '<form autocomplete="off"', $content);
}
