Question

What I want to do is a PHP script that gets all the products of a Joomla VirtueMart using PHP and mySQL. However my question has nothing to do about Joomla or PHP but I am in the need of a mySQL query.

Below you can find the tables and the fields that holds the data I need which are

product_id, product_desc, product_full_image, product_name, product_price, category_name.

To get the product_price you will need the product_id from jos_vm_product and match it with the product_id from jos_vm_product_price to get the product_price.

Every product_id has a category_id inside jos_vm_product_category_xref. So, when the category_id is found, you get the category_name from jos_vm_category.

This is difficult for me as I am not very familiar with SQL queries and I need your help on how to to join those tables, so it will allow me to echo the values I need.

Thank you.

jos_vm_poduct

product_id
product_desc
product_full_image
product_name

jos_vm_product_price

product_price

jos_vm_product_category_xref

jos_vm_category

Something like this ought to work:

SELECT jvp.product_id, product_desc, product_full_image, product_name, product_price, category_name   
FROM jos_vm_product jvp  
JOIN jos_vm_product_price jvpp  
ON jvp.product_id = jvpp.product_id  
JOIN jos_vm_product_category_xref jvpcx  
ON jvpcx.product_id = jvp.product_id  
JOIN jos_vm_category jvc  
ON jvc.category_id = jvpcx.category_id  

Any questions about why, please ask away!
