Hi there: Well as u cud see in the image below... we wer trying to have a custom rectangles overlay the base map... When we provided the bounding box coordinates directly in the form of multidimensional array; sort of like hard-coded them... everything is well and cool..
Now We r trying to assign check boxes to every array sort of like user can select/deselect his choice of rectangles..So all we did was to change the " GetRect() Function "... Although both the old & new edited functions yield the same output when I var_dump ($qresult); bt somehow this time the rectangles doesnt appear.. I tweaked the code but no success yet.. hoping sumone cud have a look & point out the error...!!@ CheckBox php Code :- <?php session_start(); //------------------------------------------ // GetRect - returns array containing store table $script_name = "index3.php"; $table = array( // array('id','state','lat_hi','long_hi','lat_low','long_low'), //field names array(1,'andaman',13.59,94,06.73,92.53), array(2,'AP', 19.87,84.78,12.59,76.45), array(3,'Gujarat',24.72,74.55,20.15,68.35), array(4,'kerala' ,12.75,77.37,08.18,74.86), array(5,'punjab' ,32.46,76.93,29.53,73.87), ); function GetRect() { if (isset($_POST['submit'])) { $tab = $_POST['tab']; $qresult = array(); foreach ($tab as $t) $qresult[] = $table[$t]; return $qresult; } } //------------------------------------------ // AddPoints - add store locations to 'poi' map layer function AddPoints ( $map, $qresult ) { $this_layer = $map->getLayerByName('poi'); $i = 0; foreach($qresult as $row) { $poi[$i] = ms_newLineObj(); $shp[$i] = ms_newShapeObj(MS_SHAPE_POLYGON); $poi[$i]->addXY($row[5],$row[4]); $poi[$i]->addXY($row[3],$row[4]); $poi[$i]->addXY($row[3],$row[2]); $poi[$i]->addXY($row[5],$row[2]); $poi[$i]->addXY($row[5],$row[4]); $shp[$i]->add($poi[$i]); $shp[$i]->set(index, $row[0]); $this_layer->addFeature( $shp[$i] ); $i++; } return; } // end AddPoints $map = ms_newMapObj("/ms4w/apache/htdocs/india_roads3.map"); $extent = array(62.786563, 7.392830, 102.765356, 36.151322); $qresult = GetRect(); AddPoints( $map, $qresult ); $image=$map->draw(); $image_url=$image->saveWebImage(); ?> CheckBox Html code <form method="POST" name="myform2" action="action="<?php echo $_SERVER['PHP_SELF']; ?>"> <?php foreach ($table as $id=>$ar) { ?> <br><input name="tab[]" type="checkbox" value="<?=$id?>">Id : <?=$id?>, Name : <?=$ar[0]?> <?php } ?> <br><br><input name="submit" value="submit" type="submit"> </form> This is the php code for GetRect() when we stored the arrays in session; which is working fine function GetStoreTable() { $i=0; $allValuesPresent=1; if (isset($_SESSION['table'])) { foreach ($_SESSION['table'] as $arr) { if (! isset($arr[$i])) { $allValuesPresent = 0; break; } // Will get overwritten by query if any are missing $qresult[$i]=$arr; $i++; } return $qresult; } } // end GetStoreTable Image:- http://osgeo-org.1803224.n2.nabble.com/file/n5650035/polygon5.jpg -- View this message in context: http://osgeo-org.1803224.n2.nabble.com/PHP-mapscript-Custom-rectangles-overlay-tp5650035p5650035.html Sent from the Mapserver - User mailing list archive at Nabble.com. _______________________________________________ mapserver-users mailing list mapserver-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapserver-users
