TOPIC: How update a readonly field

How update a readonly field 4 days 20 hours ago #43998

Hi,
I explain my problem.
In a form I have three fields mapped to a joomla db table named ‘#__cities’. The fields are:
  • sales-city, a dropdown Type populated by this query:
//<code>
$items = array();
$db = JFactory::getDbo();
$items[] = "|Selezionare[c]";
$db->setQuery("SELECT cityName FROM #__Cities ORDER BY cityName ASC");
$results = $db->loadObjectList();
foreach ($results as $result) {
    $items[] = $result->cityName . '|' . $result->cityName;
}
return implode("\n", $items);
//</code>
  • sales-zipcode read-only field
  • sales-county read-only field

    • The query that populates the sales-city field works correctly.
    I would now like that, when I select a city from the dropdown, the sales-zipcode and sales-county fields update automatically with the values retrieved from the table.
    I was thinking of resolve this with a plugin and javascript code, but there is probably an easier way to achieve this.
    Can you help me with this?
    Thank You
    Gaetano
