Mapress pro : use taxonomies to generate maps

Mappress pro, a plugin for wordpress, is worth its price : it can automatically create maps from custom fields adresses. I needed the possibility to create maps from a specific taxonomy, and this requires some hacking. here's the way to go for serious coders who want, like me, to spend one  intense hour . hope mappress pro incorporates that for future buyers !!

FIRST STEP : create a new configuration option for mappress to specify the custom taxonomy

• in mappress.php

• function set_custom_taxonomy_map() { $options = Mappress_Options::get(); echo __(" Update map when terms are added to a post in the following taxonomy ", "mappress"); echo "<input type='text' size='30' name='mappress_options[customTaxonomyMap]' value='" . $options->customTaxonomyMap. "'/>";}

  function set_custom_taxonomy_map() {        $options = Mappress_Options::get();     echo __(" Update map when terms are added to a post in the following taxonomy  ", "mappress");         echo "<input type='text' size='30' name='mappress_options[customTaxonomyMap]' value='"  . $options->customTaxonomyMap. "'/>";}

• and in mappress_api, don't forget to declare your new option as class variable of Mappress_Options
  $customTaxonomyMap=""

SECOND STEP : implement action hooks to create the map when the post is saved

• in mappress_pro.php, function Mappress_Pro()
  
  if ($options->customTaxonomyMap) { add_action('deleted_term_relationships', array(&$this, 'term_delete'), 10, 4); add_action('added_term_relationship', array(&$this, 'term_added'), 10, 4); }

  if ($options->customTaxonomyMap) {                 add_action('deleted_term_relationships', array(&$this, 'term_delete'), 10, 4);                 add_action('added_term_relationship', array(&$this, 'term_added'), 10, 4);         }

• and
  
  function getTaxonomyMapKey($taxonomy) { return "tax" . $taxonomy; } function term_added($postid, $termId) // poleouest { $options = Mappress_Options::get(); $taxonomy=$options->customTaxonomyMap; $mapMetaKey=$this->getTaxonomyMapKey($taxonomy); $pois=array(); $this->term_delete($postid, $termId); $terms=get_the_terms( $postid, $taxonomy ); foreach( $terms as $term ) { $city=$term->name; add_post_meta($postid,"hello",$city); if ($city!="") {$atts = array("address" => $city); $atts = $this->scrub_atts($atts); $poi = new Mappress_Poi($atts); $result = $poi->geocode(true); $pois[] = $poi; $map = new Mappress_Map(); // Update with new POIs $map->update(array('pois' => $pois, 'title' => $city, 'metaKey' =>$mapMetaKey, 'center' => array('lat' => 0, 'lng' => 0))); $map->save($postid); } } } function term_delete($postid, $termId) // poleouest { $options = Mappress_Options::get(); $taxonomy=$options->customTaxonomyMap; $mapMetaKey=$this->getTaxonomyMapKey($taxonomy); $map = Mappress_Map::get_post_map($postid, null, $mapMetaKey); if ($map) $map->delete(); }

  function getTaxonomyMapKey($taxonomy)   {       return "tax" . $taxonomy;   } function term_added($postid, $termId) // poleouest {      $options = Mappress_Options::get();     $taxonomy=$options->customTaxonomyMap;     $mapMetaKey=$this->getTaxonomyMapKey($taxonomy);     $pois=array();     $this->term_delete($postid, $termId);     $terms=get_the_terms( $postid, $taxonomy );       foreach( $terms as $term ) {           $city=$term->name;         add_post_meta($postid,"hello",$city);     if ($city!="")     {$atts = array("address" => $city);     $atts = $this->scrub_atts($atts);      $poi = new Mappress_Poi($atts);    $result = $poi->geocode(true);    $pois[] = $poi;     $map = new Mappress_Map();           // Update with new POIs         $map->update(array('pois' => $pois, 'title' => $city, 'metaKey' =>$mapMetaKey, 'center' => array('lat' => 0, 'lng' => 0)));         $map->save($postid);     }       } } function term_delete($postid, $termId) // poleouest {      $options = Mappress_Options::get();     $taxonomy=$options->customTaxonomyMap;     $mapMetaKey=$this->getTaxonomyMapKey($taxonomy);      $map = Mappress_Map::get_post_map($postid, null, $mapMetaKey);    if ($map)  $map->delete(); }
