How to Easily display post titles with a custom length in WordPress!

If you want to be able to easily display only the first X characters of your post title, I get something in store that might interest you. Just read this and enjoy! The first thing to display post titles with a custom length is to create the function. Open your functions.php file and paste this code:

function ODD_title($char) {
         $title = get_the_title($post->ID);
         $title = substr($title,0,$char);
         echo $title;
}

Now, you can use the function on your theme files. Just pass how many characters you want to display as a parameter. In the following example, only the first 20 chars of the title will be displayed:

<?php ODD_title(20); ?>
