'supports' => array(

Aunque deberíatener que agregar algo de validación,esta acciónnoparece ser complicadapara la versión actual de WordPress.

Básicamente,necesita dospasospara agregar un campopersonalizado a untipo depublicaciónpersonalizada:

1. Cree unmetabox que contenga su campopersonalizado
2. Guarde su campopersonalizadoen labase de datos

Estospasos se describenglobalmente aquí: http://wordpress.org/support/topic/is-it-possible-to-add-an-extra-field-to-a-custom-post-type

Ejemplo:

Agregue un campopersonalizado llamado "función" a untipo depublicaciónpersonalizada llamado "prefix-teammembers".

Primero agregueelmetabox:

 function prefix_teammembers_metaboxes( ) {
   global $wp_meta_boxes;
   add_meta_box('postfunctiondiv', __('Function'), 'prefix_teammembers_metaboxes_html', 'prefix_teammembers', 'normal', 'high');
}
add_action( 'add_meta_boxes_prefix-teammembers', 'prefix_teammembers_metaboxes' );
 

Si agrega oedita un "prefijo-miembros delequipo",se activaelenlace add_meta_boxes_{custom_post_type}. Consulte http://codex.wordpress.org/Function_Reference/add_meta_box para obtenerel add_meta_box()función. En la llamada anterior de add_meta_box()es prefix_teammembers_metaboxes_html,una devolución de llamadapara agregar su campo deformulario:

 function prefix_teammembers_metaboxes_html()
{
    global $post;
    $custom = get_post_custom($post->ID);
    $function = isset($custom["function"][0])?$custom["function"][0]:'';
?>
    <label>Function:</label><input name="function" value="<?php echo $function; ?>">
<?php
}
 

Enel segundopaso,tiene su campopersonalizadopara labase de datos. Alguardarelgancho save_post_{custom_post_type} se activa (desde v 3.7,consulte: https://stackoverflow.com/questions/5151409/wordpress-save-post-action-for-custom-posts ). Puede conectarestoparaguardar su campopersonalizado:

 function prefix_teammembers_save_post()
{
    if(empty($_POST)) return; //why is prefix_teammembers_save_post triggered by add new? 
    global $post;
    update_post_meta($post->ID, "function", $_POST["function"]);
}   

add_action( 'save_post_prefix-teammembers', 'prefix_teammembers_save_post' );   
 

Although you should have to add some validation, this action does not seem to be complicated for the current version of WordPress.

Basically you need two steps to add a Custom Field to a Custom Post Type:

1. Create a metabox which holds your Custom Field
2. Save your Custom Field to the database

These steps are globally described here: http://wordpress.org/support/topic/is-it-possible-to-add-an-extra-field-to-a-custom-post-type

Example:

Add a Custom Field called "function" to a Custom Post Type called "prefix-teammembers".

First add the metabox:

function prefix_teammembers_metaboxes( ) {
   global $wp_meta_boxes;
   add_meta_box('postfunctiondiv', __('Function'), 'prefix_teammembers_metaboxes_html', 'prefix_teammembers', 'normal', 'high');
}
add_action( 'add_meta_boxes_prefix-teammembers', 'prefix_teammembers_metaboxes' );

If your add or edit a "prefix-teammembers" the add_meta_boxes_{custom_post_type} hook is triggered. See http://codex.wordpress.org/Function_Reference/add_meta_box for the add_meta_box() function. In the above call of add_meta_box() is prefix_teammembers_metaboxes_html, a callback to add your form field:

function prefix_teammembers_metaboxes_html()
{
    global $post;
    $custom = get_post_custom($post->ID);
    $function = isset($custom["function"][0])?$custom["function"][0]:'';
?>
    <label>Function:</label><input name="function" value="<?php echo $function; ?>">
<?php
}

In the second step you have your custom field to the database. On saving the save_post_{custom_post_type} hook is triggered (since v 3.7, see: https://stackoverflow.com/questions/5151409/wordpress-save-post-action-for-custom-posts). You can hook this to save your custom field:

function prefix_teammembers_save_post()
{
    if(empty($_POST)) return; //why is prefix_teammembers_save_post triggered by add new? 
    global $post;
    update_post_meta($post->ID, "function", $_POST["function"]);
}   

add_action( 'save_post_prefix-teammembers', 'prefix_teammembers_save_post' );

Sé queestapreguntaes antigua,peropara obtenermásinformación sobreeltema

WordPresstiene soporteintegradopara campospersonalizados.Sitiene untipo depublicaciónpersonalizada,todo lo quenecesitaesincluir 'campospersonalizados' dentro de lamatriz de soporte dentro de register_post_type como respondió @kubante

Tengaen cuenta queesta opcióntambiénestá disponibleparatipos depublicacionesnativas,comopublicaciones ypáginas,solotiene que activarla

Ahora Este campopersonalizadoesmuybásico y acepta una cadena como valor.Enmuchos casosesoestábien,peropara camposmás complejos,le aconsejo que useel complemento 'Campospersonalizados avanzados'

I know this question is old but for more info about the topic

WordPress has built-in support for custom fields. If you have a custom post type then all you need is to include 'custom-fields' inside the support array inside of register_post_type as answered by @kubante

Note that this option is also available for native post types like posts and pages you just need to turn it on

Now This custom field is very basic and accepts a string as a value. In many cases that's fine but for more complex fields, I advise that you use the 'Advanced Custom Fields' plugin

 // slider_metaboxes_html , function for create HTML 
function slider_metaboxes( ) {
   global $wp_meta_boxes;
   add_meta_box('postfunctiondiv', __('Custom link'), 'slider_metaboxes_html', 'slider', 'normal', 'high');
}

//add_meta_boxes_slider => add_meta_boxes_{custom post type}
add_action( 'add_meta_boxes_slider', 'slider_metaboxes' );
