I have a map with a grid on it. each cell of the grid

  • 0

I have a map with a grid on it. each cell of the grid will be a clickable area on the map via image map coords. I would like to do this dynamically to save writing all this code for the image maps, but I can’t quite figure out the statement or equation i need to use.
Here is an example of what I have of the image map so far.

<div style="text-align:center;" id="location_title">The Hearth Lands</div>
                        <img id="map1" src="./images/maps/regions/1.png" usemap="#map1" border="0" width="800" height="800" alt="" />
                        <map name="map1" id="_map1">
                            <area shape="rect" coords="0,0,50,50" href=""  alt="" title="" />
                            <area shape="rect" coords="50,0,100,50" href=""  alt="" title="" />

    $columns = 5;
$rows = 5;
$width = 50;
$height = 50;

for( $x = 0; $x < $columns; $x++ )
{
   for( $y = 0; $y < $rows; $y++ )
   {
      $a = ($x * $width);
      $b = ($y * $height);

      $coords = array( $a, $b, ($a + $width), ($b + $height) );
      echo '<area shape="rect" coords="'.implode( ',', $coords ).'" href="'.$href.'" alt="'.$alt.'" title="'.$title.'" />';
   }
}
