    <p>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.</p> <p>Below you can find the tables and the fields that holds the data I need which are</p> <p><strong>product_id, product_desc, product_full_image, product_name, product_price, category_name.</strong></p> <p>To get the <strong>product_price</strong> you will need the <strong>product_id</strong> from <code>jos_vm_product</code> and match it with the <strong>product_id</strong> from <code>jos_vm_product_price</code> to get the <strong>product_price</strong>.</p> <p>Every <strong>product_id</strong> has a <strong>category_id</strong> inside <code>jos_vm_product_category_xref</code>. So, when the <strong>category_id</strong> is found, you get the <strong>category_name</strong> from <code>jos_vm_category</code>.</p> <p>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.</p> <p>Thank you.</p> <p><strong>jos_vm_poduct</strong></p> <pre><code>product_id product_desc product_full_image product_name </code></pre> <p><strong>jos_vm_product_price</strong></p> <pre><code>product_id product_price </code></pre> <p><strong>jos_vm_product_category_xref</strong></p> <pre><code>product_id category_id </code></pre> <p><strong>jos_vm_category</strong></p> <pre><code>category_id categroy_name </code></pre>

    2. COThe structure has to stay as is. My question was not how to edit the DB but how to make use of it to get some data.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
