查询两个Joomla3 / Virtuemart3表并获取字段值的代码

Question

My SQL and php skills are very limited especially when it comes to Joomla. For at least a day now I am trying to write a query for two Joomla3 Virtuemart3 tables and get the datas but I cannot. The tables are #__virtuemart_order_userinfos and #__virtuemart_orders common fields for both are the virtuemart_order_id the fields that I need, to start with, from the two tables are:

1. __virtuemart_order_userinfos :

   virtuemart_order_id company last_name first_name

2. __virtuemart_orders :

   virtuemart_order_id order_number order_total

The rest I can add, I think....

I probably need to have a JOIN for the two tables and select the correct fields based on virtuemart_order_id

Could you write for me the code for Joomla so I can add it to a php file I have created for Invoice and Receipt?

Thank you in advance

Answer 1

please try the query below in joomla ..

$db = JFactory::getDbo();

$query = $db->getQuery(true);

$query->select(array('a.virtuemart_order_id','a.order_total','a.order_number', 'b.company', 'b.last_name','b.first_name'))

->from($db->quoteName('#__virtuemart_orders', 'a'))

->join('Left', $db->quoteName('#__virtuemart_order_userinfos', 'b') . ' ON (' . $db->quoteName('a.virtuemart_order_id') . ' = ' . $db->quoteName('b.virtuemart_order_id') . ')');

$db->setQuery($query);

$results = $db->loadObjectList();

You can also apply conditions in where clause or can use order clause for ordering for the result. please check the link for further guidance - https://docs.joomla.org/Selecting_data_using_JDatabase
