    <p>UPDATE: THIS IS SOLVED AND THE WORKING CODE IS PASTED IN THE BOTTOM OF THIS POST. I KEEP THE ORIGINAL POST SO OTHERS CAN READ AND FOLLOW.</p> <p>I have had a big problem going Live with PayPal but think I have found the issue.</p> <p>Look at this screenshot, it is from the pdt.php where customers are redirected to after purchase and it is a real one, did with a real visa: <a href="http://snag.gy/5XCvA.jpg" rel="nofollow">http://snag.gy/5XCvA.jpg</a></p> <p>I have printed the whole TX-id at the top for debugging and here I can see that item_number1=54, quantity1=1 and item_name1=Introduktionsföreläsning.</p> <p>The problem is that these do not show under Produkt, ID and Antal(Product, Id and Quantity) which is used to be presented to the customer. This is because I have the variables set like this:</p> <pre><code>$item_number = $response[item_number]; $item_name = $response[item_name]; $qty = $response[quantity]; </code></pre> <p>and they never get anymore than just item_number, when they need to get "++:ed" to item_number1, item_number2 etc for every product.</p> <p>I have tried to do a lot of changes, for example: </p> <pre><code>for($idx = 1; $idx &lt; $count; $idx ++) { //$item_name .=$idx ++; //$item_name = $item_name++; echo ("&lt;div class='abouttext'&gt;Produkt: ".$item_name."&lt;/div&gt;\n"); echo ("&lt;div class='abouttext'&gt;ID: ".$item_number."&lt;/div&gt;\n"); echo ("&lt;div class='abouttext'&gt;Antal: ".$qty."&lt;/div&gt;\n"); echo ("&lt;br /&gt;"); } </code></pre> <p>Where the outcommented lines is where I try to append a number to item_name but I just get "1" or nothing at all as an answer when I need it to be item_name1 and so on.</p> <p>Here is my PDT script: But im pretty sure it can be fixed in this area of code: <a href="http://pastebin.com/L2nyT9q7" rel="nofollow">http://pastebin.com/L2nyT9q7</a></p> <pre><code>$array_keys = array_keys($response); $count = 1; foreach($array_keys as $element) { if (!strncmp('item_number', $element, strlen('item_number'))) $count++; } for($idx = 1; $idx &lt; $count; $idx ++) { if (isset($string1) &amp;&amp; 'item_name' != null) { //$item_name .=$idx ++; //$item_name = $item_name++; echo ("&lt;div class='abouttext'&gt;Produkt: ".$item_name."&lt;/div&gt;\n"); echo ("&lt;div class='abouttext'&gt;ID: ".$item_number."&lt;/div&gt;\n"); echo ("&lt;div class='abouttext'&gt;Antal: ".$qty."&lt;/div&gt;\n"); echo ("&lt;br /&gt;"); } } </code></pre> <p>Also: I have read on some forums with people with similar problems and they have gotten replies to use item_nameX as the variable name and I have tried that too, without any other result. If I hardcode <code>$item_number = $response[item_number1];</code> &lt;- where I specify the 1 I will get the correct details. I have tested that.</p> <p>WORKING CODE:</p> <pre><code>$array_keys = array_keys($response); $count = 1; $i = 1; foreach($array_keys as $element) { if (!strncmp('item_number', $element, strlen('item_number'))) $count++; } for($idx = 1; $idx &lt; $count; $idx ++ &amp; $i++) { $item_number = $response[item_number . $i]; $item_name = $response[item_name . $i]; $qty = $response[quantity . $i]; echo ("&lt;div class='abouttext'&gt;Produkt: ".$item_name."&lt;/div&gt;\n"); echo ("&lt;div class='abouttext'&gt;ID: ".$item_number."&lt;/div&gt;\n"); echo ("&lt;div class='abouttext'&gt;Antal: ".$qty."&lt;/div&gt;\n"); echo ("&lt;br /&gt;"); } </code></pre>

    1. CO(edited) You have something bad with logic there: 'item_name' is a string, so it's never null. And the code overall is extremely hard to read because of style.

    2. COYes that is true, thanks. But I dont think it even served a function, I deleted it and I have the same result. Only name showing, but that indicates that it still can find the name, but still the item_name is just item_name and not item_name1 for example. Ill update the code.

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.
