Limit the word count in the post title

Question

Is there a way to limit the word count of the post title?

I searched over the internet but found nothing.

All I know is, only the content of the post can be limited or excerpted.

Answer 1

There is a built-in function for that: wp_trim_words().

add_filter( 'the_title', 'wpse_75691_trim_words' );

function wpse_75691_trim_words( $title )
{
    // limit to ten words
    return wp_trim_words( $title, 10, '' );
}

Answer 2

function limit_word_count($title) {
    $len = 5; //change this to the number of words
    if (str_word_count($title) > $len) {
        $keys = array_keys(str_word_count($title, 2));
        $title = substr($title, 0, $keys[$len]);
    }
    return $title;
}
add_filter('the_title', 'limit_word_count');

You can put any kind of limit on almost anything you like, you just need the correct filter

Answer 3

simply use this where ever you want to display your title with limited words

<?php echo wp_trim_words( get_the_title(), 5 ); ?>

replace number 5 in above code with whatever number of words you need to display.

Regards.
