Copying URLs from Google Maps fails validation

[timClicks]

Just had feedback from a user. They used Google Maps to find a location. Then they copied that URL into our form for location on the form submission field. The validation failed.

It would be useful to allow people to do this, to avoid them needing to do things twice.

function llextract( $in ) {
$llregex = "/[&?]ll=(-{0,1}\d{1,2}.\d{1,9}),(-{0,1}\d{1,3}.\d{1,9})/"; //
$matches = preg_match( $llregex, $in, $res );
if ($matches != 1) return FALSE;
elseif ((abs($res[1])>90) || (abs($res[2])>180)) return FALSE;
else {
$res["lon"] = $res[2]; // 4 with old regex
$res["lat"] = $res[1]; // 2 with old regex
$res["datum"] = "WGS84";
return $res;
}
};
