How to add snippets to files

[brindamair]

Hello everyone:
I understand the usefulness of snippets but there is no clear instructions on their website on how to add such to functions.php.
They can not go anywhere. It is evident, but you only indicate "add to functions.php or footer.php, etc", no more.
I do not want to use plugins.

This happens to me every time I want to add a snippet.
I read everything I find on the subject, without success.

For example, when I add the snippet of gravatar
**********************
add_filter ('avatar_defaults' 'sp_gravatar');
sp_gravatar function ($ avatar) {
$ Custom_avatar = get_stylesheet_directory_uri (). '/images/gravatar.png';
$ Avatar [$ custom_avatar] = "Custom Gravatar";
return $ avatar;
****************************
YOUR instructions: add to functions.php. This is not enough for beginners
I tried elsewhere in functions.php but my website disappears

Can I get some more precise instruction for add snippets without breaking my website (altitude pro) or should I continue betting to luck?
Obviously I'm not webmaster. I'm just a trainee with very good disposition and I trust StudioPress and Genesis but you speak for webmasters.

I think this problem would find a solution with a tutorial showing precisely where to include the snippet in the file. If this tutorial already exists, as I find it.

Thank you

PHP is a very unforgiving language. If you even have 1 incorrect character, it can take down your site. The code you have above is all wrong. The snippet code on the Studio Press works if you cut and paste it into functions.php. It doesn't matter where it goes in functions.php, but it does have to be copied exactly as it is written. In the code above you've transposed the function name and function declaration. You have curved quotes instead of straight quotes. You have a space before the $ and variable name and in some cases you've capitalized variable names and used them as lower case later on. This makes them two different entities.

Learn how to cut and paste the code exactly as it is presented and you won't have problems.

//* Display a custom Gravatar
add_filter( 'avatar_defaults', 'sp_gravatar' );
function sp_gravatar ($avatar) {
	$custom_avatar = get_stylesheet_directory_uri() . '/images/gravatar.png';
	$avatar[$custom_avatar] = "Custom Gravatar";
	return $avatar;
}
