Examples

Default Usage

The call to get post types returns the registered post types. 

<?php $post_types=get_post_types(); ?>

Output a list all registered post types

<?php 
$post_types=get_post_types('','names'); 
foreach ($post_types as $post_type ) {
  echo '<p>'. $post_type. '</p>';
}
?>

Output a list of all public custom post types

<?php 
$args=array(
  'public'   => true,
  '_builtin' => false
); 
$output = 'names'; // names or objects, note names is the default
$operator = 'and'; // 'and' or 'or'
$post_types=get_post_types($args,$output,$operator); 
  foreach ($post_types  as $post_type ) {
    echo '<p>'. $post_type. '</p>';
  }
?>

Output a named post type

This example uses the 'object' output to retrieve the post type called 'property': 

<?php 
$args=array(
  'name' => 'property'
);
$output = 'objects'; // names or objects
$post_types=get_post_types($args,$output); 
  foreach ($post_types  as $post_type ) {
    echo '<p>' . $post_type->name . '</p>';
  }
?>

Notes

Be careful when retrieving "public" custom post-types that were registered using the register_post_type() function: the inputs to the register_post_type function are not intelligently processed, so if you verbosely set options for publicly_queriable, show_ui, show_in_nav_menus, and exclude_from_search, this is NOT considered equivalent to setting the public option and querying for public post-types will not yield results that were defined with the equivalent explicit arguments. See bug 18950.

WordPress builtin post types:

  • post - WordPress built-in post type

  • custom post type - any custom post type (Since 3.0)

Change Log

    • Added the operator parameter.
  • Since: 2.9
