[OpenLayers-Users] boundingboxes selection

[Florian Thürkow]

Hello!

I have a map, which display several different bounding-boxes, the coordinates for which derive from the_geom. 
By clicking a bbox a template starts to runs, displaying the data from the entity.

Here is the problem:

There are several identical bboxes, one upon the other, but the user is only able to select one at a time. 

I tried to identify the identical bboxes from the array "$foo" and changed the coordinates
of those that are identical. This is unfortunately still not the appropriate way to do it.

$foo =    array(
            array(-10, 50, 5, 60),
            array(-122.6, 37.6, -122.3, 37.9),
            array(10, 10, 20, 20),
            array(-75, 41, -71, 44),
            array(10, 10, 20, 20),
            array(-122.6, 37.6, -122.3, 37.9),
            array(10, 10, 20, 20)
        );


 
 
$keys = array_keys($foo);
foreach($keys as $key)
{
    $blubb = implode("#", $foo[$key]);
 
    if(!empty($tmp[$blubb]))
    {
        for($i=0; $i<count($foo[$key]); $i++) {  
 $foo[$key][$i]+=$tmp[$blubb]; }
        $tmp[$blubb]++;
    }
    else
    {
        $tmp[$blubb] = 1;
    }
}
 
print_r($foo);


Are there any possibilities to visualize several bboxes, which lie on top of each other, in such a way that the user is able to select the suitable one? Maybe by using a selective attribute?


Thanks for your help!
