Come imposto dinamicamente il titolo della pagina?

Non c'è documentazione,mapuoi sempre applicare unfiltro a the_titlein questomodo:

 add_filter('the_title','some_callback');
function some_callback($data){
    global $post;
    // where $data would be string(#) "current title"
    // Example:
    // (you would want to change $post->ID to however you are getting the book order #,
    // but you can see how it works this way with global $post;)
    return 'Book Order #' . $post->ID;
}

There is no documentation on it but you could always apply a filter to the_title like this:

add_filter('the_title','some_callback');
function some_callback($data){
    global $post;
    // where $data would be string(#) "current title"
    // Example:
    // (you would want to change $post->ID to however you are getting the book order #,
    // but you can see how it works this way with global $post;)
    return 'Book Order #' . $post->ID;
}

Apartire da Wordpress 4.4,puoi utilizzareilfiltro Wordpress document_title_partspermodificareiltitolo.

Aggiungi quanto segue a functions.php:

 add_filter('document_title_parts', 'my_custom_title');
function my_custom_title( $title ) {
  // $title is an array of title parts, including one called `title`

  $title['title'] = 'My new title';

  if (is_singular('post')) {
    $title['title'] = 'Fresh Post: ' . $title['title'];
  }

  return $title;
}
 

As of Wordpress 4.4, you can use the Wordpress filter document_title_parts to change the title.

Add the following to functions.php:

add_filter('document_title_parts', 'my_custom_title');
function my_custom_title( $title ) {
  // $title is an array of title parts, including one called `title`

  $title['title'] = 'My new title';

  if (is_singular('post')) {
    $title['title'] = 'Fresh Post: ' . $title['title'];
  }

  return $title;
}

Per coloro che desideranomodificare l'attributo title del documento,ho scoperto che l'utilizzo delfiltro wp_titlenonfunzionapiù.Utilizzainveceil ilfiltro pre_get_document_title :

 add_filter("pre_get_document_title", "my_callback");
function my_callback($old_title){
    return "My Modified Title";
}

For those wishing to change the document's title attribute, I found that using the wp_title filter no longer works. Instead, use the pre_get_document_title filter:

add_filter("pre_get_document_title", "my_callback");
function my_callback($old_title){
    return "My Modified Title";
}

Quando hai Yoast abilitato,devi sovrascrivereiltitoloin questomodo:

 add_filter('wpseo_title', 'custom_titles', 10, 1);
function custom_titles() {

  global $wp;
  $current_slug = $wp->request;

  if ($current_slug == 'foobar') {

    return 'Foobar';
  }
}
 

When having Yoast enabled you need to override the title like so:

add_filter('wpseo_title', 'custom_titles', 10, 1);
function custom_titles() {

  global $wp;
  $current_slug = $wp->request;

  if ($current_slug == 'foobar') {

    return 'Foobar';
  }
}

Dipende davvero se stai cercando di visualizzare untitolopersonalizzatoper lapagina corrente (ovveroi contenuti deltag <title></title>nell'intestazione) o difiltrareiltitolodipaginenel corpo dellapagina oneglielenchi.

Really depends if you're looking to display a custom title for the current page (i.e. the contents of the <title></title> tag in the header) or filter the title of pages in the page body or in listings.

In the former case (the title of the current page), try adding a filter for wp_title() like so: http://codex.wordpress.org/Plugin_API/Filter_Reference/wp_title

If you want to modify page titles across the board, filtering the_title() will do the trick: http://codex.wordpress.org/Plugin_API/Filter_Reference/the_title

In realtàilmodopiù sempliceperfarlo è utilizzare una riga dijs.

Inserisciil seguente codicenelmodello:

 <script>document.title = "<?php echo $new_title; ?>";</script>
 

Questo codicenon deveesserenell'intestazione html,puòessereinseritonel corpo html.

Actually the easiest way to do this is use one line of js.

Put the following code in the template:

<script>document.title = "<?php echo $new_title; ?>";</script>

This code doesn't has to be in the html header, it can be put in the html body.
