Found a solution
I found an integrated solution with a little code writing.
I have created a view with two exposed filters:
Search: Search Terms
Location: Distance / Proximity
(Im using exposed fields for the resone I could no use 'Search: Search Terms' as an argument, by the end of this proccess, the exposed filters can be turned invisible by CSS)
Now I have a search form on top of the view with key word, latitude and longitude, distance and units. Too much information!
I have created a new block I can show on top of every page:
function myproject_block($op = 'list', $delta = 0, $edit = array()) {
switch ($op) {
case 'list':
$blocks[0] = array('info' => t('search by location'));
return $blocks;
case 'view':
switch ($delta) {
case 0:
$output = drupal_get_form('myproject_search_by_location_form');
$block = array(
'content' => $output,
);
break;
}
}
return $block;
}
function myproject_search_by_location_form() {
$form['what'] = array(
"#type" => "textfield",
"#title" => t('What'),
"#maxlength" => 255,
"#size" => 20,
"#required" => false,
'#weight' => 5,
);
$form['where'] = array(
"#type" => "textfield",
"#title" => t('Where'),
"#maxlength" => 255,
"#size" => 20,
"#required" => false,
'#weight' => 10,
);
$form['submit'] = array(
"#type" => "submit",
"#value" => t('Find now'),
'#weight' => 15,
);
return $form;
}
The submit function sould take the two parameter, transform them into keyword, latitude ad longitude. and then redirect back to the view (the path for the view page is 'location_search/views')
function myproject_search_by_location_form_submit($form, &$form_state) {
$param['keys'] = null;
$param['distance[latitude]'] = null;
$param['distance[longitude]'] =null;
$param['distance[distance]'] = null;
$param['distance[search_distance]'] = null;
$param['distance[search_units]'] = 'mile';
if($form_state["values"]["what"]) {
$param['keys'] = $form_state["values"]["what"];
}
if($form_state["values"]["where"]) {
$latlong = myproject_string_to_latlog($form_state["values"]["where"]);
if($latlong) {
$param['distance[latitude]'] = $latlong['lat'];
$param['distance[longitude]'] = $latlong['lon'];
$param['distance[distance]'] = 25;
$param['distance[search_distance]'] = 25;
$param['distance[search_units]'] = 'mile';
}
}
drupal_goto('location_search/views',$param);
}
function myproject_string_to_latlog($query) {
// code borowed from location/geocoding/google.inc at location module
$key = variable_get('location_geocode_google_apikey', '');
if (function_exists('gmap_get_key')) {
$key = gmap_get_key();
}
$service_url = 'http://maps.google.com/maps/geo?output=xml&key='. $key .'&q=';
$http_reply = drupal_http_request($service_url . urlencode($query));
$status_code_match = array();
preg_match('/<code>(.)<\/code>/', $http_reply->data, $status_code_match);
$status_code = $status_code_match[1];
if ($status_code != 200) {
return NULL;
}
$accuracy_code_match = array();
preg_match('/Accuracy="([0-9])"/', $http_reply->data, $accuracy_code_match);
$accuracy_code = $accuracy_code_match[1];
if ($accuracy_code < 3) {
return NULL;
}
$latlon_match = array();
preg_match('/<coordinates>(.)<\/coordinates>/', $http_reply->data, $latlon_match);
$latlon_exploded = explode(',', $latlon_match[1]);
return array('lat' => $latlon_exploded[1], 'lon' => $latlon_exploded[0]);
}
Please test it and comment it if you wish. What I like to know is how can this feature can packed as a module that includes this specific view.

I'm trying to take the standard Drupal search results page and have it display through a block, but a block that comes from a view that I can control. Is your code above useful for that? Sounds like it might be.
