Add/edit the supports argument ( while using register_post_type ) to include the custom-fields to post edit screen of you custom post type:

Bien que vous devriez avoir à ajouter une validation,cette actionne semblepas compliquéepour la version actuelle de WordPress.

Engros,vous avezbesoin de deux étapespour ajouter un champpersonnalisé à untype depublicationpersonnalisé:

1. Créez unemétabox contenant votre champpersonnalisé
2. Enregistrez votre champpersonnalisé dans labase de données

Ces étapes sont décritesglobalementici: http://wordpress.org/support/topic/is-it-possible-to-add-an-extra-field-to-a-custom-post-type

Exemple:

Ajoutez un champpersonnalisé appelé "fonction" à untype demessagepersonnalisé appelé "prefix-teammembers".

Ajoutez d'abord lamétabox:

 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 vous ajoutez oumodifiez un "prefix-teammembers",le hook add_meta_boxes_{custom_post_type}est déclenché. Voir http://codex.wordpress.org/Function_Reference/add_meta_box pour la add_meta_box()fonction. Dans l'appel ci-dessus de add_meta_box()est prefix_teammembers_metaboxes_html,un rappelpour ajouter votre champ deformulaire:

 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
}
 

Dans la deuxième étape,vous avez votre champpersonnalisé dans labase de données. Lors de l'enregistrement,le hook save_post_{custom_post_type}est déclenché (depuis la version 3.7,voir: https://stackoverflow.com/questions/5151409/wordpress-save-post-action-for-custom-posts ). Vouspouvez accrocher cecipourenregistrer votre champpersonnalisé:

 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' );

There are various plugins for custom meta boxes and custom fields. If you look at a plugin that focuses on developers, then you should try Meta Box. It's lightweight and very powerful.

If you're looking for a tutorial on how to write code for a meta box / custom fields, then this is a good start. It's the first part of a series that might help you refine the code to make it easy to extend.

Je sais que cette questionest ancienne,maispourplus d'informations sur le sujet

WordPress a un supportintégrépour les champspersonnalisés.Si vous avez untype depublicationpersonnalisé,tout ce dont vous avezbesoinest d'inclure des 'champspersonnalisés' dans letableau de support à l'intérieur de register_post_type comme répondupar @kubante

Notez que cette optionest également disponiblepour lestypes depublicationnatifstels que lespublicationset lespages dontil vous suffit de l'activer

Maintenant Ce champpersonnaliséesttrèsbasiqueet accepte une chaîne comme valeur.Dans denombreux cas c'estbien maispour les champsplus complexes,je vous conseille d'utiliser leplugin 'Advanced Custom Fields'

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' );
