Question

So i am generating a XML file based on data from mysql tables but need to be able to get the data i want from 2 tables using my query and unsure how to do this. details are as follows:

TABLE: store_locations
===================================
store_location_id
country
latitude
longitude
===================================

TABLE: store_locations_descriptions
===================================
store_location_id
name
description
city
===================================

PHP Function:

// Function to generate XML file based on store data from database
function fn_store_locator_generate_xml(){
    $qur = db_get_field("JOIN QUERY WANTED HERE");
    $ans=mysql_query($qur);
    $output.= "<?xml version=\"1.0\" encoding=\"UTF-8\"?>
<kml xmlns=\"http://earth.google.com/kml/2.2\">
<Document>";
    while($row=mysql_fetch_array($ans))
    {
      $output.="<name>".$row['name']."</name>";
      $output.="<description>".$row['description']."</surname>";
      $output.="<Placemark>";
      $output.="<name>".$row['name']."</name>";
      $output.="<Snippet>".$row['description']."</Snippet>";
      $output.="<description>".$row['description']."</description>";
      $output.="<Point>";
      $output.="<coordinates>".$row['latitude'].",".$row['longitude']."</coordinates>";
      $output.="</Point>";
      $output.="</Placemark>";
      $output.="</person>";
    } 
    $output.="</Document>";

    $file_name = "galleries.xml";
    $file_pointer = fopen($file_name, "w+");
    fwrite($file_pointer, "$output");
    fclose($file_pointer);
}
// generate the XML file
fn_store_locator_generate_xml();

Many Thanks in advance!

Looks like you just need a join. I’m assuming you have 1 to 1 relationship between these tables.

select s.store_location_id,
    s.country,
    s.latitude,
    s.longitude,
    d.name,
    d.description,
    d.city
from store_locations s
    join store_locations_descriptions d
    on s.store_location_id = d.store_location_id

You should certainly look into how joins work:
