    <p>I am using shopify webhook to update my sql server's 'qty' field when order updated, below is my php code</p> <pre><code>?php $xmlData = fopen('php://input' , 'rb'); while (!feof($xmlData)) { $xmlString .= fread($xmlData, 4096); } fclose($xmlData); $xml = new SimplexmlElement($xmlString); file_put_contents('orders/order' . '.xml', $xmlString); $dom = new DomDocument(); $dom-&gt;load('orders/order.xml'); $itemList = $dom-&gt;getElementsByTagName('line-item'); foreach($itemList as $item) { $sku=''; $qty=''; foreach($item-&gt;childNodes as $child) { if ($child-&gt;localName == 'sku') { $sku = $child-&gt;textContent; } if ($child-&gt;localName == 'quantity') { $qty = $child-&gt;textContent; } } mysql_connect ("?????????????????????????"); mysql_select_db("??????????"); $query = "UPDATE xcart_categories SET product_count = product_count - $qty WHERE description='$sku';"; mysql_query($query); } </code></pre> <p>and below is xml file i am getting from shopify webhook</p> <pre><code>&lt;?xml version="1.0" encoding="UTF-8"?&gt; &lt;order&gt; &lt;buyer-accepts-marketing type="boolean"&gt;true&lt;/buyer-accepts-marketing&gt;

</code></pre> <p></p> <p>like you see i got two sku and qty because of duplicated line-item so for example when customer order one "product name - test in this case i got "-2" quantity update in my sql server sku test field , but when i am using webhook event when order creation it worked i mean i see only one line item but all the other cases(when order updated, when order payment, when order fullfillment..) show me duplicated line item even there is only one item ordered i think i am parsing my XML badly anyone who can teach me correct code to pull 'line items' from the first line-items node i will really appreciate it! Thanks..again</p>

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.
