How to change default text for specific post type

Question

Prelude:

Let's say the text "Comments are closed" is a default WP String and you wanna change that text string to something else like "Hello World!" if is_singular('post-type') is true.

Issue:

Now, I do know that there is a plugin called Say What? which does this exact thing, you just have to provide the string of text and the respective text domain. But the problem is that whatever you change in this plugin it will become global for the entire website. You cannot use and conditional check and then change the text if the condition is true.

So, can any of you let me know if I can change the text without this plugin via normal code so that I can use any conditional statement I want.

Any help will be appreciated. Thanks.

Yes you can do it, just find the file where the text resides, maybe single.php or single-{post_type}.php or archive-{post_type}.php Then, look for the string you want to change erase it and set a variable, something like this:

If the file where the string is, is a template file for that specific post type, the you will only replace the string for whatever you want:

<h2>Comments are closed<h2> //Replace comments are closed for Hello World

Remember the strings you find in comments, footer or sidebar are in separate files, and, in that case, and in the case the file that is giving the HTML structure to the post type is single.php, you'll have to do something like this inside the loop:

<?php
$post_type = get_post_type( get_the_ID() ); 
$the_string = "comments are closed";
if ($post_type === "my_post_type") {
$the_string = "Hello World!";
}
?>

<h2><?php echo $the_string; ?></h2>
