Parexemple ...

 add_action('init', 'reg_tax');
function reg_tax() {
   register_taxonomy_for_object_type('category', 'attachment');
}

Ajoute un champ de saisie "Catégorie" augestionnairemultimédiaet à l'éditeur depiècesjointes. J'aimerais savoir s'ilestpossible demodifier cettefonctionpour capturer une URL de "destination de lien" à laplace. L'URL seraitexécutée lorsque l'utilisateur clique sur l'image.

Vous devez également savoir comment récupérer la valeur de cenouveau champ.

MISE À JOUR: Merci à Thomas Answer ci-dessous,voicima solutionfinale ...

 function my_image_attachment_fields_to_edit($form_fields, $post) {  
    $form_fields["custom1"] = array(  
        "label" => __("Image Links To"),  
        "input" => "text",
        "value" => get_post_meta($post->ID, "_custom1", true)  
    );        
    return $form_fields;  
}  

function my_image_attachment_fields_to_save($post, $attachment) {    
    if( isset($attachment['custom1']) ){  
        update_post_meta($post['ID'], '_custom1', $attachment['custom1']);  
    }  
    return $post;  
}  

add_filter("attachment_fields_to_edit", "my_image_attachment_fields_to_edit", null, 2); 
add_filter("attachment_fields_to_save", "my_image_attachment_fields_to_save", null, 2);

For example...

add_action('init', 'reg_tax');
function reg_tax() {
   register_taxonomy_for_object_type('category', 'attachment');
}

Adds a "Category" input field to the media manager and attachments editor. I'd like to know if its possible to alter this function to capture a "link destination" URL instead. The URL would be executed when the image is clicked.

Also need to know how to retrieve the value for this new field.

UPDATE: Thanks to Thomas Answer below, here is my final solution...

function my_image_attachment_fields_to_edit($form_fields, $post) {  
    $form_fields["custom1"] = array(  
        "label" => __("Image Links To"),  
        "input" => "text",
        "value" => get_post_meta($post->ID, "_custom1", true)  
    );        
    return $form_fields;  
}  

function my_image_attachment_fields_to_save($post, $attachment) {    
    if( isset($attachment['custom1']) ){  
        update_post_meta($post['ID'], '_custom1', $attachment['custom1']);  
    }  
    return $post;  
}  

add_filter("attachment_fields_to_edit", "my_image_attachment_fields_to_edit", null, 2); 
add_filter("attachment_fields_to_save", "my_image_attachment_fields_to_save", null, 2);

- Ne "namespace"pas vosfonctions avec "my_".Trop degens lefont déjà.;)
  
  Don't "namespace" your functions with "my_". Too many people do that already. ;)

  Would love to know how to use this with a radio button. Changing type doesn't do anything.

  @scottb Instead of putting your solution in the question, you should cut it out of there and paste it into an answer and then accept that. Some people think there something seems off about accepting ones own answer, but its fine and it helps future searches (like me) to get to the real answer more quickly.

En réponse à la question de Drew dans les commentaires,vouspouvezpersonnaliser le code HTML du champen définissant input sur unenouvelle chaîne,puisen ajoutant cettemême chaîneen tant que clé au $form_fields.

Par défaut,WordPressn'acceptera que les textet textareapour letype input.Tout le reste devra être défini demanièrepersonnalisée comme ci-dessous.Jen'aipasessayé de conserver les champs deformulaire de cettefaçon,doncpour créer un autretype d'entrée,comme unbouton radio,celapeutprendre unpeuplus definesse.

 add_filter( 'attachment_fields_to_edit', 'change_fields', 10, 2 );
function change_fields( $form_fields, $post ) {

    $form_fields["some_new_field"] = array(  
            "label" => __("Type something"),
            "input" => "arbitrary_value",
            "value" => get_post_meta($post->ID, "some_new_field", true),
            "arbitrary_value" => "hello world!"
        );
}

Responding to Drew's question in the comments, you can customize the HTML for the field by setting the input to a new string, and then adding that same string as a key to the $form_fields array.

By default, WordPress will only accept text and textarea for the input type. Anything else will have to be defined in a custom way as below. I haven't tried actually persisting form fields this way so in order to make another input type, like a radio button, might take a little extra finesse.

add_filter( 'attachment_fields_to_edit', 'change_fields', 10, 2 );
function change_fields( $form_fields, $post ) {

    $form_fields["some_new_field"] = array(  
            "label" => __("Type something"),
            "input" => "arbitrary_value",
            "value" => get_post_meta($post->ID, "some_new_field", true),
            "arbitrary_value" => "hello world!"
        );
}
