I'm trying to get a calculator helper in product admin page, near the price input I want to add a textbox that helps users to calculate the price with Tax VAT exluded to insert. It's something similar to this <a href="http://www.opencart.com/index.php?route=extension/extension/info&extension_id=7045" rel="nofollow">PLUGIN</a> but I need to query the database to get an array of all Tax Rates and compare them with the <code>tax_class_id</code> selected by user just below the price. I have found a sort of request in this page: <code>admin/controller/localisation/tax_rate.php</code> <pre class="lang-php prettyprint-override"><code>if (isset($this->request->post['rate'])) { $this->data['rate'] = $this->request->post['rate']; } elseif (!empty($tax_rate_info)) { $this->data['rate'] = $tax_rate_info['rate']; } else { $this->data['rate'] = ''; } </code></pre> But I have no idea how to query the database and get the data inside the page <code>admin/view/template/catalog/product_form.tpl</code>. I'm trying to get a result similar to Prestashop's price management. Please give me some help! EDIT: I solved with this code added in <code>admin/controller/catalog/product.php</code> placed inside getForm() function: <pre><code>$sql = 'SELECT tra.rate, tra.type, tru.tax_class_id FROM '.DB_PREFIX.'tax_rate tra LEFT JOIN '.DB_PREFIX.'tax_rule tru ON tru.tax_rate_id = tra.tax_rate_id WHERE tru.tax_class_id IS NOT NULL' ; $query = $this->db->query($sql); $rates = array(); foreach($query->rows as $result){ $rates[] = $result; } $this->data['rates'] = $rates; </code></pre> thanks to all the participants

Guidance

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.
