Add function to wordpress theme

Question

So I've got this function and i want it to run in a certain moment in page.php, but i don't know where to place it: i've tried going into functions.php doing this:

function orario($giorno){
if(get_field($giorno)){
the_field($giorno);
} else {
echo 'Nessuna Lezione';
}
}

add_action('init', 'orario');

But the result is the function run at the top of the theme's pages for some reason, and when i call it somewhere else it doesn't work. Any help? Is there another way to do the same thing?

Try finding a different hook. You are using init you should probably find a different hook on wordpress.org that betters suits you're needs
