When the user enters to edit / create a post using the Wordpress admin, the metabox labur_add_metabox is created, which contains a input de tipo text empty and a button.

The action labur_init is also executed in which a js file is registered ( labur.js ).

The labur.js file is executed when the user clicks on the id=button_labur_get_url button

From labur.js the function labur_get_url_process is executed, which must pick up the url of the current post and return it to the js file.

Code of labur.php

//show metabox in post editing page
add_action('add_meta_boxes', 'labur_add_metabox' ); // Creación de metabox personlaizado

//load external files
add_action( 'add_meta_boxes', 'labur_init' ); // 'add_meta_boxes' tal vez no sea correcto. Tal vez sea mas correcto otro Hook

// add admin settings
add_action('wp_ajax_labur_get_url', 'labur_get_url_process'); // El prefijo wp_ajax es por convención de wordpress


// Función para procesar el AJAX
function labur_get_url_process() {
  global $post;
  echo get_permalink( $post->ID );
}

/**
 * load external files
 */
function labur_init() {
    //register plugin js file. Jquery is a requirement for this script so we specify it
    wp_register_script( 'labur-js', plugins_url( '/labur.js', __FILE__ ), array('jquery') );

    //load scripts
    wp_enqueue_script('jquery'); 
    wp_enqueue_script('labur-js'); 

}

function labur_add_metabox() {
    //doc http://codex.wordpress.org/Function_Reference/add_meta_box
    add_meta_box('labur_url', 'Bidalketaren labur.eus helbidea','labur_url_handler', 'post', 'side', 'high'); 
}

/**
 * metabox handler
 */
function labur_url_handler() {
    echo '<input type="text" id="labur_shortened_url" name="labur_direccion" readonly />';
    echo '<p class="submit"><input id="button_labur_get_url" class="button button-primary button-large" name="labur_url" value="Sortu labur helbidea" type="button"/></p>';
}

Code labur.js

jQuery(document).ready(function($) {
    jQuery("#button_labur_get_url").click(function(){
    var url = document.location.protocol+'//'+document.location.host+'/aldakurnet/wp-admin/admin-ajax.php';
    jQuery.ajax({
            type: 'POST',
            url: url,
            dataType: 'text',
            data: {
                action: 'labur_get_url', // Ejecuta labur_get_url_process
            },
            success: function(data, textStatus, XMLHttpRequest){
                $('#labur_shortened_url').val(data);
            },
            error: function(MLHttpRequest, textStatus, errorThrown){
                alert(errorThrown);
            }
        });
    });
});

If you are in the Wordpress administration section you should not use $ post- & ID; $ _ REQUEST ["post"] .

The $ post-> ID is used as long as $ post is loaded with the element generated by other functions such as wp_query or get_posts.

The solution passes using isset in labur_get_url_process

labur_ìnit Send labur.js an object Ajax with post_id and action to execute.

The labur.js receives the parameters and executes labur_get_url_process to then write the result in a input with id=labur_shortened_url

Code of labur.php:

<?php

//show metabox in post editing page
add_action('add_meta_boxes', 'labur_add_metabox' ); // Creación de metabox personlaizado

//load external files
add_action( 'add_meta_boxes', 'labur_init' ); 

// add admin settings
add_action('wp_ajax_labur_get_url', 'labur_get_url_process'); // El prefijo wp_ajax es por convención de wordpress



// Función para procesar el AJAX
function labur_get_url_process() {
    if(isset($_POST['postID'])) 
    {
      $post_id = $_POST['postID'];
      $post_url = get_permalink($post_id);
      echo $post_url;
    }

    exit();
}

/**
 * load external files
 */
function labur_init() {
    //register plugin js file. Jquery is a requirement for this script so we specify it
    wp_register_script( 'labur-js', plugins_url( '/labur.js', __FILE__ ), array('jquery') ); 
    //load scripts
    wp_enqueue_script('jquery'); 
    wp_enqueue_script('labur-js'); 

    global $post;
    $post_id = $post->ID;
    wp_localize_script('labur-js', 'MyAjax', array(
      'post_id' => $post_id,
      'action'=> 'labur_get_url' // labur_get_url es la acción pero sin el prefijo wp_ajax. Esta acción ejecutará la función labur_get_url_process
    ));

}

?>

Code labur.js

jQuery(document).ready(function($) {
    jQuery("#button_labur_get_url").click(function(){
    var url = document.location.protocol+'//'+document.location.host+'/aldakurnet/wp-admin/admin-ajax.php';
    jQuery.ajax({
            type: 'POST',
            url: url,
            dataType: 'text',

            data: {
                postID: MyAjax.post_id, 
                action: MyAjax.action 
            },
            success: function(data, textStatus, XMLHttpRequest){
                $('#labur_shortened_url').val(data);
            },
            error: function(MLHttpRequest, textStatus, errorThrown){
                alert(errorThrown);
            }
        });
    });
});
