Use

You must use the WordPress tools to get the database. WPDB is your friend.
You can write the code directly in your template or in functions.php of your theme.

Name of the table : ($wpdb->prefix)geonames

Names of the columns :

• idwpgn (bigint)
• geonameid (bigint)
• name (varchar)
• asciiname (varchar)
• alternatenames (text)
• latitude (decimal)
• longitude (decimal)
• feature_class (char)
• feature_code (varchar)
• country_code (varchar)
• cc2 (varchar)
• admin1_code (varchar)
• admin2_code (varchar)
• admin3_code (varchar)
• admin4_code (varchar)
• population (bigint)
• elevation (int)
• dem (smallint)
• timezone (varchar)
• modification_date (date)

Feature Class & Code here.

Example : get GPS position for a specific city in a specific country :

global $wpdb;
$s = $wpdb->get_row("SELECT latitude, longitude 
    FROM ".$wpdb->prefix."geonames 
    WHERE name='Paris' and country_code='FR' ");
echo $s->latitude . " - " . $s->longitude;

Example : 10 most populous cities in Switzerland :

global $wpdb;
$s = $wpdb->get_results("SELECT name, population 
    FROM ".$wpdb->prefix."geonames 
    WHERE country_code='CH' and feature_class='P' 
    ORDER BY population DESC 
    LIMIT 10");
foreach($s as $t) {
    echo $t->name. " : " . $t->population . "<br />";
}

Example : hotels within 40 km from Marbella (ES) :

global $wpdb;
$p = $wpdb->get_row("SELECT latitude, longitude 
    FROM ".$wpdb->prefix."geonames 
    WHERE name='Marbella' and country_code='ES' ");
$dlat = 40 / 1.852 / 60;
$dlon = 40 / 1.852 / 60 / cos($p->latitude * 0.0174533);
$s = $wpdb->get_results("SELECT name, latitude, longitude
    FROM ".$wpdb->prefix."geonames 
    WHERE country_code='ES' and 
        feature_code='HTL' and 
        latitude<".($p->latitude+$dlat)." and
        latitude>".($p->latitude-$dlat)." and
        longitude<".($p->longitude+$dlon)." and
        longitude>".($p->longitude-$dlon)."
    LIMIT 100");
foreach($s as $t) {
    $d = (floor(sqrt(pow(($p->latitude-$t->latitude)*60*1.852,2)+pow(($p->longitude-$t->longitude)*60*1.852*cos($p->latitude * 0.0174533),2))));
    if($d<=40) echo $t->name. " : " . $d . " km<br />";
}

Example : Suggest cities during the typing by the user (like Google search)

You must use Ajax action and PHP function with the name “wpgeonamesAjax”

In your theme, in function.php ; add :
function wpgeonamesAjax() {
global $wpdb;
$s = $wpdb->get_results(“SELECT name
FROM “.$wpdb->prefix.”geonames
WHERE country_code=’FR’ and feature_class=’P’ and name LIKE ‘”.strip_tags($_POST[“city”]).”%’
ORDER BY name
LIMIT 10″);
foreach($s as $t) {
echo ‘

‘.$t->name.’

‘;
}
}

In your theme, in the right page ; add :

<input id="inpCity" name="inpCity" type="text" onkeyup="sugg(this,'<?php echo admin_url('admin-ajax.php'); ?>');" />
<div class="suggCity" id="suggCity"></div>
<script>
function sugg(f,g){
    jQuery(document).ready(function(){
        jQuery.post(g,{'action':'wpgeonamesAjax','city':f.value},function(r){
            jQuery('#suggCity').empty();jQuery('#suggCity').append(r.substring(0,r.length-1));
        });
    });
}
</script>
