Is there a way to have always the the_title(); tag also includes a custom field called subtitle?

I want to have a title like this: "subtitle-custom-fild: Posttitle"

Like "Cool: The new TV show from Werner Herzog."

in this case, cool would be the custom field value, and "the new TV...." would be the_title().

I am getting this at the moment with the following code:

<h1><?php $values = get_post_custom_values("myCustomField"); echo $values[0]; ?>: <?php the_title(); ?>"><?php $values = get_post_custom_values("myCustomField"); echo $values[0]; ?>
<p><?php the_title(); ?></p></h1>

The Problem is, that google indexes the posts sometimes with the custom field in title, sometimes without it - which in some cases makes no sense. I also gave all possible "title tags" the complete title the same way in the "title=" attribute....

Is there any way to tell wordpress - if theres a custom field subtext - print it always in front of the post_title?

Thank you!

What theme are you using? Link it please (if custom: show your header.php code). And please also edit your post and format code properly. Thanks. – kaiser Sep 5 '12 at 15:51

function add_subtitle($title, $id) {
    $subtitle = get_post_meta($id, 'myCustomField', true);
    $new_title = $title;
        $new_title = $subtitle . ': ' . $new_title;
    return $new_title;
add_filter('the_title', 'add_subtitle', 10, 2);

Basically, this uses the the_title filter to add the subtitle to your title. It only adds it if that custom field is available, otherwise, it leaves the title alone.

+1, I was writing similar answer, but you beat me, so added an alternative method. – amit Sep 5 '12 at 16:46
Using filter is recommended unless you don't want the change globally ( ie - Other plugin/function using the_title() or get_the_title() gets the new formatted title if filter is used ) – amit Sep 5 '12 at 16:49
@amit which is why I did a check for that custom field he is using as the subtitle. If the post doesn't have it, the title isn't effected. – Manny Fleurmond Sep 5 '12 at 16:54
Thank you!! I will give it a try! – ad2003 Sep 6 '12 at 8:25

the_title() Accept parameters, we can use them to pass the custom field value to show either before or after the title.

Example -

<?php the_title( get_post_meta($post->ID, 'myCustomField', TRUE) ); ?>

Note - Make sure you set the 3rd parameter as TRUE, which will return a single STRING,

Edit #1-

 *  The OneLiner ( Note the DOT between two strings ) 
 *  OutPut - Foo: the post title
the_title( get_post_meta($post->ID, 'myCustomField', TRUE) . ': ');

Reference Codex - Function Reference - the title()

Didn't realize it took arguments like that. Pretty sweet. – Manny Fleurmond Sep 5 '12 at 16:14
Nice - and how can I set that the custom field shows up before the title? And how could I do a ':' betwenn them? – ad2003 Sep 6 '12 at 14:12
great! thanks amit! – ad2003 Sep 7 '12 at 1:39
