Plugin Jsonp Gis

This is a plugin we initially developed for building soundmap mashups.
Its name is Jsonp Gis Plugin and so far it is done for the CMS SPIP. In the future there will be also a WordPress version.

You can download it from SPIP-Zone server:
Jsonp-gis SPIP plugin

The plugin is just two jsonp files that work as an API. It allows people to get the geolocated content from a SPIP site and show it in a different server.

jsonpgis_all.html

The first file is jsonpgis_all.html and it is loaded as follows:
http://urlofmywebsite/spip.php?page=jsonpgis_all

It lists all geolocated articles. The tags that are included in the json are:

latitude
longitude
id

The reason why it has so few tags is because we want to load a high number of articles at once, and we want to make it fast. So we only put the information necessary for locating a marker in a map, which is latitude and longitude. We also put the id of the article because we could need it if we want to get more information about the article, using the other file of the plugin: jsonpgis_one.html

We can add several parametres ir order to get the results we want to achieve:

id_rubrique
It returns articles from a given “rubrique”
We should always pass at least one rubrique as a parameter. If we don’t do so, we get 0 results.
example: http://urlofmywebsite/spip.php?page=jsonpgis_all&id_rubrique=1

callback
It returns jsonp instead of json
example: http://urlofmywebsite/spip.php?page=jsonpgis_all&id_rubrique=1&callback=?
This is how json looks like:

[{"lat": "43.1791","lon": "-7.45435","id":"1891"},{"lat": "43.3115","lon": "-8.54908","id":"1889"}]

And this is how jsonp looks like if we pass “?” as the callback parameter:

?([{"lat": "43.1791","lon": "-7.45435","id":"1891"},{"lat": "43.3115","lon": "-8.54908","id":"1889"}])

id_auteur
it returns articles from a given editor-user
example: http://urlofmywebsite/spip.php?page=jsonpgis_all&id_rubrique=1&id_auteur=1

recherche
it returns articles from a given search request
example: http://urlofmywebsite/spip.php?page=jsonpgis_all&id_rubrique=1&recherche=water

id_mot
it returns articles from a given tag
example: http://urlofmywebsite/spip.php?page=jsonpgis_all&id_rubrique=1&id_mot=1

limit
it limits the number of articles the query returns. For example, if we put limit=10, we only get 10 articles
example: http://urlofmywebsite/spip.php?page=jsonpgis_all&id_rubrique=1&limit=10

All parameters can be combined in order to get different results.
For example, with the following query we get a jsonp with the last 20 articles from rubrique=1, autor=3 that include the word “water”:
http://urlofmywebsite/spip.php?page=jsonpgis_all&id_rubrique=1&id_auteur=3&recherche=water&limit=20&callback=?

Here is an example of how this jsonp looks like:

[
	{
		"lat": "43.1791",
		"lon": "-7.45435",
		"id":"1891"
	},{
		"lat": "43.3115",
		"lon": "-8.54908",
		"id":"1889"
	},{
		"lat": "43.3112",
		"lon": "-8.55329",
		"id":"1888"
	}
]

jsonpgis_one.html

The second file is jsonpgis_one.html and it is loaded as follows:
http://urlofmywebsite/spip.php?page=jsonpgis_one&id_article=xxx

It lists all information related to an article. The tags that are included in the json are:

title: Title of the article
description: Description of the article
date: Date when the article was published in standar format
permalink: The permalink to the article
url_sound: The url of the sound attached to the article. It only lists the last sound attached
url_image: The url of the image attached to the article. It only lists the last image attached, which is 400px width and has proportional height.
lat: latitude
lon: longitude
user: name of the user who published the article
id: id of the article

It is possible to pass two parameters: id_article and callback:

id_article
it is mandatory to add this parameter. It corresponds to the id of the article from which we want to get information. If we don’t do so we get no result.
example: http://urlofmywebsite/spip.php?page=jsonpgis_one&id_article=322

callback
It returns jsonp instead of json
example: http://urlofmywebsite/spip.php?page=jsonpgis_one&id_article=322&callback=?

Here is an example of how this jsonp looks like:

{
	"title":"Title of the article",
	"description":"Description of the soundscape",
	"date":"2011-10-09 13:33:47",
	"permalink":"http://urlofmywebsite/title-of-the-article",
	"url_sound":"http://urlofmywebsite/IMG/mp3/name-of-the-audio-file.mp3",
	"url_image":"http://urlofmywebsite/IMG/mp3/name-of-the-image-file.jpg",
	"lat":"41.956",
	"lon":"-8.82992",
	"sound_tracker":"user",
	"id":"322"
}

Whatif PLugin + APP

Vimos de publicar un plugin para o xa framework WordPress co que abrimos conexión entre o theme Whatif (proxecto de Ecosistema Urbano) e un dispositivo Android (dende 1.6 ata 2.3.4 Gingerbread). Foi un parto longo, sobre todo porque o protocolo XML-RPC de WordPress ten limitacións importantes como a posibilidade de usar Custom Taxonomies ou os Custom Post Types. Tivemos que escribir código no plugin para habilitar estas novas funcións que forman parte do Framework Whatif.

A APP Android, que tamén foi programada no Estudo Pumpún, foi escrita seguindo o traballo da orixinal WordPress for Android e permite, entre outras…

“[…] introducir y etiquetar mensajes desde cualquier lugar, detectando automáticamente tu posición o dejándote elegirla, e incluyendo la posibilidad de adjuntar una fotografía en el mismo momento de publicar. También permite la consulta del contenido por ubicación, etiquetas, galería imágenes o lista de mensajes.”

Que é Whatif Móvil?

Como o seu propio nome indica, é a aplicación móbil de Whatif, concibida para consultar e publicar entradas desde calquera lugar, cunha interfaz secuencial similar pero adaptada á pantalla dun smartphone. Esta aplicación conéctase con calquera instalación da versión web de Whatif, sincronizando con esta os textos da interfaz e os contidos.

E o Plugin Whatif?

É o interface entre a máquina Android e o Framework Whatif. Son varias as funcións que incorpora e que foron necesarias para habilitar esta comunicación entre máquinas:

*Activa automaticamente o protocolo XML-RPC de publicacion remota en wordpress (por defecto ven desactivado).
*Ampla os métodos de entrada via protocolo XML-RPC (como a posibilidade de ler dinámicamente taxonomías especiáis).
*Permite a publicación de novos post que incorporan estas Custom Taxonomies.
*incorpora miniaturas na lista de post que se visualizan no panel de control de WordPress.
*Define as dimensións por defecto da miniatura saltándose a configuracioón por defecto de WordPress.

Detalles no código do Plugin

Por exemplo, esta función ben simple, activa o protocolo XML-RPC do WordPress si non estivera activado.

// AUTOMATICALLY TURNS THE XML-RPC PROTOCOL ON IN WORDPRESS
// ACTIVA AUTOMATICAMENTE EL PROTOCOLO XML-RPC DE PUBLICACION REMOTA EN WORDPRESS
update_option('enable_xmlrpc', '1');

Este outro cacho de código engade esa vista de miniaturas á lista de entradas no wordpress. Engade unha columna á dereita e dunha ollada permite coñecer cales post levan asociada unha imaxe (moi importante para o modo de visualización de imaxes da APP Android)

// ADD TUMBNAILS IN MANAGE POST/PAGES LIST
// INCORPORA MINIATURAS EN LA LISTA DE POST QUE SE VISUALIZA EN EL PANEL DE CONTROL DE WORDPRESS
 
if ( !function_exists('AddThumbColumn') && function_exists('add_theme_support') ) {
    // for post and page
    add_theme_support('post-thumbnails', array( 'post', 'page' ) );
    function AddThumbColumn($cols) {
        $cols['thumbnail'] = __('Thumbnail');
        return $cols;
    }
    function AddThumbValue($column_name, $post_id) {
            $width = (int) 60;
            $height = (int) 60;
            if ( 'thumbnail' == $column_name ) {
                // thumbnail of WP 2.9
                $thumbnail_id = get_post_meta( $post_id, '_thumbnail_id', true );
                // image from gallery
                $attachments = get_children( array('post_parent' => $post_id, 'post_type' => 'attachment', 'post_mime_type' => 'image') );
                if ($thumbnail_id)
                    $thumb = wp_get_attachment_image( $thumbnail_id, array($width, $height), true );
                elseif ($attachments) {
                    foreach ( $attachments as $attachment_id => $attachment ) {
                        $thumb = wp_get_attachment_image( $attachment_id, array($width, $height), true );
                    }
                }
                    if ( isset($thumb) && $thumb ) {
                        echo $thumb;
                    } else {
                        echo __('None');
                    }
            }
    }
    // for posts
    add_filter( 'manage_posts_columns', 'AddThumbColumn' );
    add_action( 'manage_posts_custom_column', 'AddThumbValue', 10, 2 );
    // for pages
    add_filter( 'manage_pages_columns', 'AddThumbColumn' );
    add_action( 'manage_pages_custom_column', 'AddThumbValue', 10, 2 );
}

E atención a estoutro que permite automatizar a Featured Image de cada artigo/post. Unha das formas de visualización de propostas/artigos da aplicación para Android é a través das imaxes que os usuarios toman da rúa con seus teléfonos. Cando o teléfono saca unha foto (ou adxunta unha da galería persoal), pégase ó artigo que está publicando e a imaxe envíase no momento da publicación. Pois ben, este cacho de código que se pode ver a continuación, permite que anque unha imaxe non se defina como Featured Image nun artigo/post de WordPress, a función colle a primeira imaxe do post e a define como Featured Image, o que permite navegar a través das imaxes e tamén visualizar a lista delas na propia lista de artigos no wordpress.

// CONVERTIR AUTOMATICAMENTE LA PRIMERA IMAGEN ASOCIADA A UN POST EN IMAGEN DESTACADA
if ( function_exists( 'add_theme_support' ) ) {
 
add_theme_support( 'post-thumbnails' );
 
      function easy_add_thumbnail() {
 
          global $post;
 
          $already_has_thumb = has_post_thumbnail();
 
              if (!$already_has_thumb)  {
 
              $attached_image = get_children( "post_parent=$post->ID&post_type=attachment&post_mime_type=image&numberposts=1" );
 
                          if ($attached_image) {
 
                                foreach ($attached_image as $attachment_id => $attachment) {                            	
                                add_post_meta($post->ID, '_thumbnail_id', $attachment_id, true);                                 
                                }     
 
                           }
 
                        }
      } // fin funcion
 
  add_action('the_post', 'easy_add_thumbnail');
 
  // hooks added to set the thumbnail when publishing too
  add_action('new_to_publish', 'easy_add_thumbnail');
  add_action('draft_to_publish', 'easy_add_thumbnail');
  add_action('pending_to_publish', 'easy_add_thumbnail');
  add_action('future_to_publish', 'easy_add_thumbnail');
 
} else {
 
    function eat_fail_requirements() {
 
      echo "<!-- Easy Add Thumbnail activated, but your WordPress doesn't support add_theme_support function -->";
 
    }
 
  add_action('wp_head', 'eat_fail_requirements');
 
}

E para rematar, aquí tedes o código completo do Plugin que incorpora un bo lote de funcións para ampliar as características do Protocolo XML-RPC. Unha morea de novas funcións que permiten incorporar os grandes pasos que deu o Framework WordPress neste último ano: a incorporación de tipos de post e a incorporación de taxonomías personalizadas que convirten, cando menos, un sistema de blog ordenado cronolóxicamente, nun potente CMS cuxos límites están na cabeza de quen traballa con eles.

Plugin jsonp SPIP

Descrición

O plugin “jsonp” da a posibilidade a SPIP de xerar un arquivo jsonp con contidos dos artigos publicados, para poder acceder a eles dende dominios diferentes ao que se atopa instalado o CMS.

Para tal efecto se crean dous arquivos:

1. o chamado jsonp-all que inclúe por defecto todos os campos que se poden poñer nun artigo máis os documentos adxuntos ao mesmo. Cuxa url sería http://url_do_sitio_spip/spip.php?page=jsonp-all
Exemplo en liña: http://www.berio.alg-a.org/spip.php?page=jsonp-all

2. o chamado jsonp que é configurable e permite poñerlle só aqueles campos que se queren dar a difundir. Así como os documentos clasificados por tipo.Cuxa url sería http://url_do_sitio_spip/spip.php?page=jsonp
Exemplo en liña: http://www.berio.alg-a.org/spip.php?page=jsonp

Baixar

Podes baixar o plugin no seguinte enderezo: plugin jsonp SPIP

Compatibilidade

O plugin é compatible coas seguintes versións de SPIP: SPIP 2.1
Asimesmo precisa da instalación do plugin CFG

Configuración

Para a súa configuración é preciso ter instalado o plugin CFG.

Este é o panel de configuración que afectará tan só ao arquivo jsonp:

Onde podemos ver que se permite seleccionar as seccións que conteñen os artigos que queremos que aparezan no jsonp, así como o número de artigos e os campos, que son: sobretítulo, título, subtítulo, descrición, cabeceira, pé, visitas, popularidade, idioma, notas, introducción, url do artigo, logotipo, logotipo de paso de rato, palabras clave, audios, imaxes e documentos.

Lectura do jsonp por jQuery

A chamada ao jsonp a través de jQuery debe ser feita coa variable callback=?, é decir, a url debería ser a seguinte (sustituíndo “url_da_miña_paxina” pola url verdadeira da túa páxina):
http://url_da_miña_paxina/spip.php?page=jsonp&callback=?
ou o que é o mesmo en código SPIP:
[(#URL_PAGE{jsonp})&callback=?] o [(#URL_PAGE{jsonp-all})&callback=?]

O plugin trae un exemplo de como poder ler o jsonp a través de jQuery. Que podedes consultar aquí: http://www.berio.alg-a.org/spip.php?page=example-load-jsonp

De todas formas aquí tedes o código, seguindo a documentación propia de jQuery respecto ao jsonp:

<script type="text/javascript">
	$(document).ready(function(){
		$.getJSON('[(#URL_PAGE{jsonp})&callback=?]', function(data){
			$.each(data, function(entryIndex, entry){
				var li_id = "articulo_" + entry['id_article'];
	         	$("ul#warper").append(
	         		"<li class='articulo' id='" + li_id + "'><ul></ul></li>"
	         	);
	         	$("li#" + li_id + " ul").append(
	         		"<li><span>titulo: </span>" + entry['titre'] + "</li>"
	         		+"<li><span>id: </span>" + entry['id_article'] + "</li>"
	         		+"<li><span>sobretitulo: </span>" + entry['surtitre'] + "</li>"
	         		+"<li><span>subtitulo: </span>" + entry['soustitre'] + "</li>"
	         		+"<li><span>url: </span>" + entry['url_article'] + "</li>"
	         		+"<li><span>descriptivo: </span>" + entry['descriptif'] + "</li>"
	         		+"<li><span>cabeceira: </span>" + entry['chapo'] + "</li>"
	         		+"<li><span>pe de artigo: </span>" + entry['ps'] + "</li>"
	         		+"<li><span>visitas: </span>" + entry['visites'] + "</li>"
	         		+"<li><span>popularidade: </span>" + entry['popularite'] + "</li>"
	         		+"<li><span>idioma: </span>" + entry['lang'] + "</li>"
	         		+"<li><span>notas: </span>" + entry['notes'] + "</li>"
	         		+"<li><span>introduccion: </span>" + entry['introduction'] + "</li>"
	         		+"<li><span>logo: </span>" + entry['logo_article'] + "</li>"
	         		+"<li><span>logo de substitucion: </span>" + entry['logo_article_survol'] + "</li>"
	         	);
	      	});
	   	});
	});
</script>

Co correspondente html:

<body>
<ul id="warper">
</ul>
</body>

No que tan só hai un “ul” contenedor, xa que o resto do html é cargado dinamicamente co código javascript ao ler o jsonp.
