Boas pessoal,
Tenho estado a tentar atualizar uns códigos postais cp4+cp3 com os dados referentes à latitude e longitude. Aqui no forum encontrei um post do Cusco, que disponibilizava todas as ferramentas. Tentei reproduzir os passos todos, mas ao associar as coordenadas gps, ele apenas pesquisa por CP4. No ficheiro final do Cusco as coordenadas também são referentes a CP4.. por alguma razão o código não consegue pesquisar por cp4-cp3.
Alguem me pode dar uma ajuda a tentar ver se o código pode ser melhorado?
Fonte:
$mysqli = new mysqli('localhost', 'root', '', 'CTT');
$qry = "select distinct CP4, CP3 from codigosPostais where LONGITUDE = '' AND LATITUDE = '' order by CP4 asc, CP3 asc limit 2500";
$qid = $mysqli->query($qry);
if($qid->num_rows == 0){
echo "No results in database to update\n";
die();
}
while($row = $qid->fetch_object()){
$geo = getGeo($row->CP4, $row->CP3);
if(!isset($geo->lat)){
echo "$row->CP4-$row->CP3|error|$geo\n";
continue;
}
$updQry = "update codigosPostais SET LONGITUDE=$geo->lat, LATITUDE=$geo->lng WHERE CP4=$row->CP4 AND CP3='$row->CP3'";
$updQid = $mysqli->query($updQry);
$aff = $mysqli->affected_rows;
echo "$row->CP4-$row->CP3|$aff\n";
#die();
}
function getGeo($cp4, $cp3){
#$url = "http://maps.googleapis.com/maps/api/geocode/json?address=$cp4-$cp3&sensor=false&components=country:PT";
