[FIXED] Get first word from Wordpress page title

Issue

Edit

Is this code ok?
It works on a dummy website, but I'm afraid to not break a live website.
If used for links, is there a problem if links have capitalization?

function shortcode_page_title( ){
return get_the_title();
}
add_shortcode( 'page_title', 'shortcode_page_title',  );

function shortcode_title_first_word( ){
$title = get_the_title();
$title_words = explode(' ', $title);
return $title_words[0];
}

add_shortcode( 'title_first_word', 'shortcode_title_first_word', );

Thanks, @ADyson, for the resources.

Initial post

I can't code :( I'm using Sepster's solution to get the page title.

function shortcode_page_title( ){
    return get_the_title();
}
add_shortcode( 'page_title', 'shortcode_page_title',  );

How can I insert another step and select only the first word of the title?

I've seen the explode function and array selection, but I don't know how to implement them.

Thank you!

Solution

If you still want to use the shortcode as the way to insert the title wherever you need it, then all you need is to combine the 2 functions above and insert it on the bottom of your functions.php file (preferably on a child theme).

 function first_word_from_title( ){
      $title = get_the_title(); // Retrieves the title
      $title_words = explode(' ', $title); // Transforms the title into an array composed of each separate word
      return $title_words[0]; // Returns the first element of the array
    }
  add_shortcode( 'page_title', 'first_word_from_title');

I don't think you need to worry about the above code causing a crash as it is only run when you insert the shortcode and not on every page load.

You can always test it first on a draft post and see if you get an error.
