    <p>I just have a little question, I can't find any answer since I don't know exactly how to formulate it on Google.</p> <p>So I have this array returned from a query:</p> <pre><code>Array ( [0] =&gt; Array ( [aad3177ec0cbced7a15fae003bdd0ff3] =&gt; Array ( [rowid] =&gt; aad3177ec0cbced7a15fae003bdd0ff3 [id] =&gt; 21 [qty] =&gt; 1 [price] =&gt; 176 [name] =&gt; KRUPS YY1305 [image] =&gt; utilities/images/products/p2070396dt.jpg [description] =&gt; Menu simplifié pour une convivialité optimale. [subtotal] =&gt; 176 ) ) ) </code></pre> <p>And I want to get all the information rowid, id, qty ... to store it through a foreach loop in another variable without knowing the name of the second array : 'aad3177ec0cbced7a15fae003bdd0ff3'. I just want to retrieve articles from a cart stored in a database when user logged out.</p> <p>So how can I say something like :</p> <pre><code>echo $myArray['0'][theNumberGoesHereAutomatically]['price']; </code></pre> <p>Ideally, my code would look like that : </p> <pre><code>foreach ($data2 as $cart){ $data = array( 'rowid' =&gt; $cart_unserialized[$token]['aad3177ec0cbced7a15fae003bdd0ff3']['rowid'], 'id' =&gt; $cart_unserialized[$token]['aad3177ec0cbced7a15fae003bdd0ff3']['id'], 'qty' =&gt; $cart_unserialized[$token]['aad3177ec0cbced7a15fae003bdd0ff3']['qty'], 'price' =&gt; $cart_unserialized[$token]['aad3177ec0cbced7a15fae003bdd0ff3']['price'], 'name' =&gt; $cart_unserialized[$token]['aad3177ec0cbced7a15fae003bdd0ff3']['name'], 'image' =&gt; $cart_unserialized[$token]['aad3177ec0cbced7a15fae003bdd0ff3']['image'], 'description'=&gt; $cart_unserialized[$token]['aad3177ec0cbced7a15fae003bdd0ff3']['description'], ); $this-&gt;cart-&gt;insert($data2); $token++; }; </code></pre> <p>without knowing the aad3177ec0cbced7a15fae003bdd0ff3.</p> <p>Any ideas? Thanks :)</p>

Querying!

 
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.
