[Plugin: Geo Mashup] Add/remove pins based upon drop down options

Hi!
I found your suggestion on issue 250

<?php
$categories = get_the_category();
$cat_ids = array();
foreach( $categories as $category ) {
  $cat_ids[] = $category->cat_ID;
}
$map_args = 'map_content=global&open_post_id=' . get_the_ID() .
  '&marker_select_center=true&marker_select_highlight=true' .
  '&marker_select_highlight=true&marker_select_attachments=true' .
  '&map_cat=' . implode(',', $cat_ids);
echo GeoMashup::map( $map_args );
?>

Do you think it could work with custom fields?

<?php
$customfield = get_post_meta($post_id, 'my_key', 'false');

$map_args = 'map_content=global&open_post_id=' . get_the_ID() .
  '&marker_select_center=true&marker_select_highlight=true' .
  '&marker_select_highlight=true&marker_select_attachments=true';
echo GeoMashup::map( $map_args );
?>

If this worked I could use a post method to pass the variables I need and after submitting geo mashup would show the map with the parameters selected.
What do you think? Thanks!

Mmmhh nope, you are right, I wanted to know if using a function of the likes (similar to the one I wrote) I can pull out all the post IDs with a specific meta key and value (or two, or three…) and feed them to geo-mashup to create a global map.

Hello!
Thanks a lot! I did not know contextual maps supported queries! I plan on having more than 100 posts, so I hope the error mentioned in the page you sent me gets resolved in the future!
I will let you know if it works. Thanks again!

Hi,
I am using this query, which works well to output a list of posts anywhere lse on my site. But when I insert the geo-mashup code it outputs a number of blank maps equal to the number of posts that fulfill the query parameters.

<?php

 $querystr = "
SELECT $wpdb->posts.* FROM $wpdb->posts
LEFT JOIN $wpdb->postmeta ON($wpdb->posts.ID = $wpdb->postmeta.post_id)
WHERE $wpdb->posts.post_status = 'publish'
AND $wpdb->posts.post_type = 'post'
AND $wpdb->postmeta.meta_value = 'LI'
ORDER BY $wpdb->posts.post_modified DESC
";

 $pageposts = $wpdb->get_results($querystr, OBJECT);

?>
 <?php if ($pageposts): ?>
  <?php foreach ($pageposts as $post): ?>
   <?php setup_postdata($post); ?>

<?php echo GeoMashup::map( 'map_content=contextual&height=400&width=700&remove_geo_mashup_logo=true&cluster_max_zoom=11&zoom=8' ); ?>
<?php echo GeoMashup::category_legend() ?>

  <?php endforeach; ?>
 <?php endif; ?>

Guess geo mashup does not work with this kind of queries? What function should I call to use geo mashup filters? (hope what I am saying makes sense)
