Hey Ozazio, 

This is possible, you just need to adapt sample_map_multi.php (which is included with the plugin) to load the records from the different sections. Below is some sample code that shows how you could load data from sections called hotel and bars, but you can extend this to work with as many sections as you'd like. 

Step 1) Load all the records that are required on line 13 of the plugin. Replace:

  // get records
  list($myRecords, $myMetaData) = getRecords(array(
    'tableName' => $GLOBALS['GEOCODER_SAMPLE_TABLENAME'],
  ));

with the sections, you need to get the data from:

  // get records
  list($bars, $myMetaData) = getRecords(array(
    'tableName' => 'bars',
  ));

  list($hotels, $myMetaData) = getRecords(array(
    'tableName' => 'hotels',
  ));

Step 2) Update the JS at the top of the page to add each marker. Replace:

<?php
foreach ($myRecords as $record) {
  if (!$record['latitude'] || !$record['longitude']) { continue; }
  $jsFunctionArgs = "{$record['latitude']}, {$record['longitude']}, {$record['num']}, '" .jsEncode($record['_link']). "'";
  print "  _geocoder_addMarker($jsFunctionArgs);\n";
}
?>

With the same code block, but make it loads the records you retrieved previously:

foreach ($bars as $record) {
  if (!$record['latitude'] || !$record['longitude']) { continue; }
  $jsFunctionArgs = "{$record['latitude']}, {$record['longitude']}, {$record['num']}, '" .jsEncode($record['_link']). "'";
  print "  _geocoder_addMarker($jsFunctionArgs);\n";
}
foreach ($hotels as $record) {
  if (!$record['latitude'] || !$record['longitude']) { continue; }
  $jsFunctionArgs = "{$record['latitude']}, {$record['longitude']}, {$record['num']}, '" .jsEncode($record['_link']). "'";
  print "  _geocoder_addMarker($jsFunctionArgs);\n";
}

Step 3) Duplicate the marker code at the bottom of the page. Update:

    <?php foreach ($myRecords as $record): ?>

      <?php // marker_infowindow_### is the content displayed in the info-window on click ?>
      <div id="marker_infowindow_<?php echo $record['num']; ?>">
        <h3><?php echo htmlencode( @$record['address']); ?></h3>
        Add any extra content you like here...<br/>
        <a href="<?php echo $record['_link']; ?>">details</a>
      </div>

    <?php endforeach ?>

So that it is called for each set of records (as we've done above). So we'd duplicate this code twice then replace $myRecords with $blog and $hotels in each code block.

Finally, you'll need to update line 81 from this:

  <?php $hasAddresses = array_filter(array_pluck($myRecords, 'latitude')); ?>

To this:

  <?php $hasAddresses = true; ?>

Cheers,

Greg

WOW! THank you Greg!

now i have all the markers form the two tables on map... but... when i click on the markers, both restaurants and bars give me information (name, link etc) about restaurants. Of course on restaurants is correct, on bars... no.

<?php 
  // load viewer library
  $libraryPath = 'lib/viewer_functions.php';
  $dirsToCheck = array('../','../../','../../../','../../../../');
  foreach ($dirsToCheck as $dir) { if (@include_once("$dir$libraryPath")) { break; }}
  if (!function_exists('getRecords')) { die("Couldn't load viewer library, check filepath in sourcecode."); }

  // error checking
  if (!@$GLOBALS['GEOCODER_PLUGIN'])         { die("You must activate the Geocoder plugin before you can access this page."); }
  if (!@$GLOBALS['GEOCODER_GOOGLE_API_KEY']) { die("You must have a Google Maps API key to display a map, see the readme file for instructions on getting one."); }

  // get records
  list($ristoranti, $myMetaData) = getRecords(array(
      'tableName'   => 'ristoranti',  
  ));
 list($birrifici, $myMetaData) = getRecords(array(
    'tableName' => 'birrifici',
  ));

?>

Hey Orazio,

The issue is that some of the records share the same num value, and this is being used to detect which HTML content needs to be displayed when a marker is clicked on. I've updated your code in a way that should fix the problem:

<?php 
  // load viewer library
  $libraryPath = 'lib/viewer_functions.php';
  $dirsToCheck = array('../','../../','../../../','../../../../');
  foreach ($dirsToCheck as $dir) { if (@include_once("$dir$libraryPath")) { break; }}
  if (!function_exists('getRecords')) { die("Couldn't load viewer library, check filepath in sourcecode."); }

  // error checking
  if (!@$GLOBALS['GEOCODER_PLUGIN'])         { die("You must activate the Geocoder plugin before you can access this page."); }
  if (!@$GLOBALS['GEOCODER_GOOGLE_API_KEY']) { die("You must have a Google Maps API key to display a map, see the readme file for instructions on getting one."); }

  // get records
  list($ristoranti, $myMetaData) = getRecords(array(
      'tableName'   => 'ristoranti',  
  ));
 list($birrifici, $myMetaData) = getRecords(array(
    'tableName' => 'birrifici',
  ));

?>

I've updated the ID's on the hidden markers so that they are unique again by prefixing them with either b or r depending on if they're restaurants or bars.
