1) send coordinates from js to PHP: plugins/coordinates/coordinates.js
2) convert coordinates: plugins/coordinates/x_coords.php
3) many options:
3a) search via pgsql: see plugins/digitizepoints/*
3b) or use pmapper/incphp/x_ajax/x_info.php and use
json_decode($queryResult) to find your results indexes (search for
"shpindex" in the code for instance)
3c) copy / paste and modify the incphp/query/search.php and
incphp/query/query.php
3d) search the shapes with mapscript
(http://mapserver.org/mapscript/index.html ) like in this quick and
dirty example:
// prevent XSS
if (isset($_REQUEST['_SESSION'])) exit();
session_start();
require_once($_SESSION['PM_INCPHP'] . '/globals.php');
require_once($_SESSION['PM_INCPHP'] . '/common.php');
$layer = $map->getLayerByName('YOUR_LAYER_NAME');
// xy pix -> geo pt
$imgxy = $_REQUEST['imgxy'];
$tmp = explode('+', $imgxy);
$xPixel = $tmp[0];
$yPixel = $tmp[1];
$xGeo = $_SESSION['GEOEXT']['minx'] + (($xPixel/$_SESSION['mapwidth']) *
($_SESSION['GEOEXT']['minx']-$_SESSION['GEOEXT']['maxx']));
$yGeo = $_SESSION['GEOEXT']['maxy'] - (($yPixel/$_SESSION['mapheight'])
* ($_SESSION['GEOEXT']['maxy']-$_SESSION['GEOEXT']['miny']));
$pt = ms_newPointObj();
$pt->setXY($xGeo, $yGeo);
// proj
$mapProjStr = $map->getProjection();
$layerProjStr = $layer->getProjection();
if ($mapProjStr && $layerProjStr && $mapProjStr != $layerProjStr) {
$mapProjObj = ms_newprojectionobj($mapProjStr);
$layerProjObj = ms_newprojectionobj($layerProjStr);
$pt->project($mapProjObj, $layerProjObj);
}
// set map extent and size:
$map->setExtent($_SESSION['GEOEXT']['minx'],
$_SESSION['GEOEXT']['miny'], $_SESSION['GEOEXT']['maxx'],
$_SESSION['GEOEXT']['maxy']);
$map->setSize($_SESSION['mapwidth'], $_SESSION['mapheight']);
$map->preparequery();
// Use '@' to avoid warning if query found nothing
@$layer->queryByPoint($pt, MS_SINGLE, -1);
$pt->free();
// read results:
if ($layer->getNumResults() == 1) {
$res = $layer->getResult(0);
$layer->open();
$shape = layer->getFeature($res->shapeindex, $res->tileindex);
// use $shape->values to read what you want
// ......
$layer->close();
}
