    <p>I am trying to make a widget for a gallery as all the modules I have seen don't really do what I am after and widgets seem like the way forward to allow the end user to have nice and easy control over placement.</p> <p>So so far I have followed the Magento how to make a widget tutorial:</p> <p><a href="http://www.magentocommerce.com/knowledge-base/entry/tutorial-creating-a-magento-widget-part-2/" rel="nofollow">http://www.magentocommerce.com/knowledge-base/entry/tutorial-creating-a-magento-widget-part-2/</a></p> <p>which has allowed me to set up the files I need and have things recognised in the back end.</p> <p>Now I can add an image upload field through the code below but the file does not get uploaded, this is it seems due to enctype="multipart/form-data" not being set automatically when I add a file field.</p> <p>So I looked about and it seems you can add a helper block for the widget form</p> <p>local/WebsiteDevelopment/GalleryWidget/etc/Widget.xml</p> <pre><code>&lt;?xml version="1.0"?&gt; &lt;widgets&gt; &lt;WebsiteDevelopment_GalleryWidget type="widgets/list" translate="name description" module="GalleryWidget"&gt; &lt;name&gt;Banner Gallery&lt;/name&gt; &lt;description&gt;Adds a full page width gallery&lt;/description&gt; &lt;parameters&gt; &lt;enabled_services&gt; &lt;label&gt;Enabled Services&lt;/label&gt; &lt;visible&gt;1&lt;/visible&gt; &lt;required&gt;1&lt;/required&gt; &lt;type&gt;multiselect&lt;/type&gt; &lt;source_model&gt;WebsiteDevelopment_GalleryWidget_Model_Services&lt;/source_model&gt; &lt;/enabled_services&gt; &lt;helper_block&gt; &lt;type&gt;WebsiteDevelopment/GalleryWidget_Adminhtml_Edit_Form&lt;/type&gt; &lt;/helper_block&gt; &lt;template translate="label"&gt; &lt;label&gt;Frontend Template&lt;/label&gt; &lt;visible&gt;1&lt;/visible&gt; &lt;required&gt;1&lt;/required&gt; &lt;type&gt;select&lt;/type&gt; &lt;values&gt; &lt;text translate="label"&gt; &lt;value&gt;GalleryWidget/view.phtml&lt;/value&gt; &lt;label&gt;Text Links&lt;/label&gt; &lt;/text&gt; &lt;/values&gt; &lt;/template&gt; &lt;image&gt; &lt;label&gt;Image One&lt;/label&gt; &lt;description&gt;The first image for the banner&lt;/description&gt; &lt;visible&gt;1&lt;/visible&gt; &lt;type&gt;image&lt;/type&gt; &lt;/image&gt; &lt;/parameters&gt; &lt;/WebsiteDevelopment_GalleryWidget&gt; &lt;/widgets&gt; </code></pre> <p>so after i add my helper block into the params section of the xml above i create my helper at WebsiteDevelopment/GalleryWidget/Block/Adminhtml/Edit/Form.php (which i think is where it should be, i am still unsure whether a block has to be in a specific structure like this for use in the backend ) and then add the following code</p> <p>WebsiteDevelopment/GalleryWidget/Block/Adminhtml/Edit/Form.php</p> <pre><code>&lt;?php class WebsiteDevelopment_GalleryWidget_Block_Adminhtml_Edit_Form extends Mage_Adminhtml_Block_Widget_Form { protected function _prepareForm() { $form = new Varien_Data_Form(array( 'id' =&gt; 'edit_form', 'enctype' =&gt; 'multipart/form-data' )); $form-&gt;setUseContainer(true); $this-&gt;setForm($form); return parent::_prepareForm(); } } </code></pre> <p>obviously the form will need some more attributes to work fully but I was just hoping to get some different attributes on to the form so I could make sure the block was being applied.</p> <p>So at the moment when I go into the back end the form with the helper on it has no enctype still, and I am unsure if my helper block is even being loaded or whether it is and its just having no effect.</p> <p>Am I going about this in the correct manner or not?</p>

    1. COIf you are trying to create a image gallery that has albums and is spread across multiple pages then I would not use a widget. I would only use a widget if you just wanted to sisplay multiple images on 1 page that is formatted nicely. I would create a custom module that has a database table to store the data and has controllers to allow moving through the gallery. I did this for a client and mimic-ed the Admin interface for categories to allow creating albums and images.

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
