    <p>I have a cart array for a small ecommerce site i'm building and have run into a loop I can't figure out. If I have 3 different products (not sure if the number of products is relevant over 2) in my cart array (with different ID#'s) and I attempt to update the quantity of the second item, it causes an infinite loop and attempts to continuously add the product again as a new product, rather than updating the existing indentical product.</p> <pre><code> &lt;?php ///////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////// // Section 3 (if user chooses to adjust item quantity) ///////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////// if (isset($_POST['item_to_adjust']) &amp;&amp; $_POST['item_to_adjust'] != "") { // execute some code $item_to_adjust = $_POST['item_to_adjust']; $quantity = $_POST['quantity']; $quantity = preg_replace('#[^0-9]#i', '', $quantity); // filter everything but numbers if ($quantity &gt;= 100) { $quantity = 99; } if ($quantity &lt; 1) { $quantity = 1; } if ($quantity == "") { $quantity = 1; } $i = 0; foreach ($_SESSION["cart_array"] as $each_item) { $i++; while (list($key, $value) = each($each_item)) { if ($key == "item_id" &amp;&amp; $value == $item_to_adjust) { // That item is in cart already so let's adjust its quantity using array_splice() array_splice($_SESSION["cart_array"], $i-1, 1, array(array("item_id" =&gt; $item_to_adjust, "quantity" =&gt; $quantity))); } // close if condition } // close while loop } // close foreach loop } ?&gt; </code></pre> <p>I just want it to update the quantity of the existing product, not add it as another. Thanks in advance for all the help!</p>

    1. COIt is kinda hard to spot the cause.. but one key note, try using a foreach instead of a while loop Using foreach is optimized for iteration over collections. Also I am not feeling this array (array(.. thing.

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.
