Number of characters in post title

Hi there,

in your function, change this line:

if( strlen( $title ) > $max ) {

to:

if( is_archive() && strlen( $title ) > $max ) {

Great!

Thank you!

You're welcome

Hello!

I tried adding the things mentioned above, but it doesn't work for me. I have a child theme and want to limit characters on archive pages.

functions.php code:

function max_title_length( $title ) {
$max = 20;
if( is_archive() && strlen( $title ) > $max ) {
return substr( $title, 0, $max ). "…";
} else {
return $title;
}
}

arhive.php code:

add_filter( 'the_title', 'max_title_length');

Can you tell me what's wrong?

Thanks!

Hi there,

this code:

add_filter( 'the_title', 'max_title_length');

Remove that from the archive.php and it into your functions.php, before or after the other code will do.

Hello!

Still doesn't work.

Looks like this now:

function max_title_length( $title ) {
$max = 20;
if( is_archive() && strlen( $title ) > $max ) {
return substr( $title, 0, $max ). "…";
} else {
return $title;
}
}

add_filter( 'the_title', 'max_title_length');

Here's the archive page.

I've also tried placing the code above the first one.

Try this snippet instead:

add_filter( 'the_title', function( $title ){
    $max  = 20;
    if ( !is_archive() || !is_home() || $max > strlen( $title ) ) {
        return $title;
    }
    return substr( $title, 0, $max ) . "…";
}, 10, 2 );

Note - the_title function in WordPress is used in lots of places from menus to widgets. So this may affect other elements on the page.
