    <p>I am trying to sort an array inside foreach. Following is my code:</p> <pre><code>&lt;?php $_images = Mage::getModel('catalog/product')-&gt;load($_product-&gt;getId())-&gt;getMediaGalleryImages(); ?&gt; &lt;?php $i = 0; foreach ($_images as $_image){ $i++; ?&gt; &lt;img src="&lt;?php echo $this-&gt;helper('catalog/image')-&gt;init($_product, 'thumbnail', $_image-&gt;getFile())-&gt;resize(300,300); ?&gt;" style="width:50px;height:50px;"&gt; &lt;?php } ?&gt; </code></pre> <p>I need the images to be printed out in the correct order. It should be ordered by the value of: </p> <pre><code>$_image[position_default] </code></pre> <p>I have tried using Ksort:</p> <pre><code>&lt;?php $_images = Mage::getModel('catalog/product')-&gt;load($_product-&gt;getId())-&gt;getMediaGalleryImages(); ?&gt; &lt;?php $i = 0; foreach ($_images as $_image){ $i++; ?&gt; &lt;img src="&lt;?php echo $this-&gt;helper('catalog/image')-&gt;init($_product, 'thumbnail', $_image-&gt;getFile())-&gt;resize(300,300); ?&gt;" style="width:50px;height:50px;"&gt; &lt;?php ksort($_image['position']); ?&gt; &lt;?php } ?&gt; </code></pre> <p>But it does not sort them at all. Maybe i don't use it correctly? Any suggestions? :)</p> <p>Some output of $_image:</p> <pre><code>[224] =&gt; Varien_Object Object ( [_data:protected] =&gt; Array ( [value_id] =&gt; 224 [file] =&gt; /s/a/salty_fred_kn_kket.jpg [label] =&gt; [position] =&gt; 2 [disabled] =&gt; 0 [label_default] =&gt; [position_default] =&gt; 2 [disabled_default] =&gt; 0 [url] =&gt; http://webshop.simplychocolate.dk/media/catalog/product/s/a/salty_fred_kn_kket.jpg [id] =&gt; 224 [path] =&gt; /home/www/webshop.simplychocolate.dk/media/catalog/product/s/a/salty_fred_kn_kket.jpg ) [_hasDataChanges:protected] =&gt; [_origData:protected] =&gt; [_idFieldName:protected] =&gt; [_isDeleted:protected] =&gt; [_oldFieldsMap:protected] =&gt; Array ( ) [_syncFieldsMap:protected] =&gt; Array ( ) ) [247] =&gt; Varien_Object Object ( [_data:protected] =&gt; Array ( [value_id] =&gt; 247 [file] =&gt; /i/m/image_150.jpg [label] =&gt; [position] =&gt; 3 [disabled] =&gt; 0 [label_default] =&gt; [position_default] =&gt; 1 [disabled_default] =&gt; 0 [url] =&gt; http://webshop.simplychocolate.dk/media/catalog/product/i/m/image_150.jpg [id] =&gt; 247 [path] =&gt; /home/www/webshop.simplychocolate.dk/media/catalog/product/i/m/image_150.jpg ) [_hasDataChanges:protected] =&gt; [_origData:protected] =&gt; [_idFieldName:protected] =&gt; [_isDeleted:protected] =&gt; [_oldFieldsMap:protected] =&gt; Array ( ) [_syncFieldsMap:protected] =&gt; Array ( ) ) [258] =&gt; Varien_Object Object ( [_data:protected] =&gt; Array ( [value_id] =&gt; 258 [file] =&gt; /a/v/avatar.png [label] =&gt; [position] =&gt; 3 [disabled] =&gt; 0 [label_default] =&gt; [position_default] =&gt; 3 [disabled_default] =&gt; 0 [url] =&gt; http://webshop.simplychocolate.dk/media/catalog/product/a/v/avatar.png [id] =&gt; 258 [path] =&gt; /home/www/webshop.simplychocolate.dk/media/catalog/product/a/v/avatar.png ) [_hasDataChanges:protected] =&gt; [_origData:protected] =&gt; [_idFieldName:protected] =&gt; [_isDeleted:protected] =&gt; [_oldFieldsMap:protected] =&gt; Array ( ) [_syncFieldsMap:protected] =&gt; Array ( ) ) </code></pre>

    1. COYou need to sort your array before the `foreach` loop.

    2. COI can't tell if you want to sort by the `$_image['position']` key or the `$_images[key]` key?

    3. CO$_image is going to be a single image. Sorting a single-element array is pointless. You need to ksort $_images, and since you're sorting a specific key, probably need to use uksort.

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.
