I have a snippet

<?php
include("geo/geoipcity.inc");
include("geo/geoipregionvars.php");
$gi = geoip_open("/home/asens/public_html/geo/GeoLiteCity.dat", GEOIP_STANDARD);

$record = geoip_record_by_addr($gi, $_SERVER['REMOTE_ADDR']);
if($record->country_code == "US"){
echo '[[$domesticResponse]]';
}
else{
echo '[[$intlResponse]]';
}
geoip_close($gi);

I would like to have the default be [[$domesticResponse]] and [[$intlResponse]] but wish to have the option of setting these in the snippet call for something other than the default. What changes do I need to make to the above code in order to set those as the default or to select a chunk at the call?

try

<?php

$tplDomesticResponse = $modx->getOption('tplDomesticResponse', $scriptProperties, 'domesticResponse');
$tplIntlResponse = $modx->getOption('tplIntlResponse', $scriptProperties, 'intlResponse');

include ("geo/geoipcity.inc");
include ("geo/geoipregionvars.php");
$gi = geoip_open("/home/asens/public_html/geo/GeoLiteCity.dat", GEOIP_STANDARD);

$record = geoip_record_by_addr($gi, $_SERVER['REMOTE_ADDR']);
if ($record->country_code == "US") {
    $output = $modx->getChunk($tplDomesticResponse);
} else {
    $output = $modx->getChunk($tplIntlResponse);
}
geoip_close($gi);

return $output;

Bruno, follow up question if you don't mind. If I want to use that script somewhere else on the page I will get an error. How can I use the result elsewhere without re-querying?

Just a note -- if those properties exist in the snippet's default properties and are empty, the default value in the snippet won't be used unless you use true as a fourth argument to getOption():

$tplDomesticResponse = $modx->getOption('tplDomesticResponse', $scriptProperties, 'domesticResponse', true);
$tplIntlResponse = $modx->getOption('tplIntlResponse', $scriptProperties, 'intlResponse', true);

If you need values elsewhere on the page (as long as it's below your snippet tag), here's one way:

$modx->setPlaceholder('somePlaceholder', $value);

The value will be available later in the page with either a placeholder tag or in a snippet with:

$value = $modx->getPlaceholder('somePlaceholder');
