Falls man auf seine wordpress Installation von einer unabhängigen Seite (d.h. ein "leeres" PHP-Script) zugreifen möchte, kann man wie folgt die wordpress API einbinden:
API Einbinden
<?php
/<em> include wordpress API </em>/
define('WP_USE_THEMES', false);
require('./wp-blog-header.php');
?> |
<?php
/<em> include wordpress API </em>/
define('WP_USE_THEMES', false);
require('./wp-blog-header.php');
?>
Nun stehen einem im Script alle [http://codex.wordpress.org/Function_Reference/|Funktionen von wordpress] zur Verfügung!
Hier zwei Beispiele, wie man damit die letzten drei posts abruft und wie man selbst einen neuen post erstellt:
Die letzten 3 Posts abrufen:
<?php
global $post;
$args = array( 'posts_per_page' => 3 );
$myposts = get_posts( $args );
foreach( $myposts as $post ) : setup_postdata($post); ?>
<a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link to <?php the_title_attribute(); ?>"><?php the_title(); ?></a><br />
<?php endforeach; ?> |
<?php
global $post;
$args = array( 'posts_per_page' => 3 );
$myposts = get_posts( $args );
foreach( $myposts as $post ) : setup_postdata($post); ?>
<a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link to <?php the_title_attribute(); ?>"><?php the_title(); ?></a><br />
<?php endforeach; ?>
Einen neuen Post erstellen (sehr nützlich bei Migrationen von einem anderen CMS)
