Nooku Guides

Your First Todo List View

Your component Views are how you present your data to the world.

We got you started off in the Frontend part of the tutorial by creating a file called


Open it up and lets get to work showing our todo items!

Remember, we're using

Display Data in the Template

Writing templates in Nooku Framework is like writing regular HTML and PHP, but simpler. Add the following code to your open template file:

    <? foreach($items as $item) : ?>
    <? endforeach; ?>

This code will render an unordered list and for each entity in $items object it will render a <li> element with the Todo Item's id, title, and its description.

Some important notes about our code:

  1. We are using PHP short tags:

    • <? instead of <?php
    • <?= instead of <?php echo

      If short tags are disabled in your php.ini file, Nooku will automatically rewrite them as normal tags. So you don't have to worry about compatibility issues with some server setups. Again, you can use normal tags as well, but this is more compact.

  2. We are using the PHP alternative syntax for control structures such as the foreach statement, once again for readability.

  3. We can simply use $items in the above example instead of $this->items. Nooku will by default assign items data to the items view if you don't tell it otherwise...More Magic

  4. Note that we have only added a template here; no View class. This is because Nooku will fallback on default classes whenever your component does not contain a specific class that it's looking for, in this case the items HTML view. So when ComTodoViewItemsHtml is not found, it will simply fall back on ComKoowaViewHtml, and assume that since you're requesting the items view, that you want to view a list of Todo items.

Tip: You can also add a 'default' view class for your component, ComTodoViewHtml, if you want to use that as a fallback instead of ComKoowaViewHtml. For HTML format requests your new class still needs to descend from KViewHtml.

Again, take note of the following: "items" implies multiple items, while "item" implies a single post. Everywhere in Nooku, it's very important to use singular and plural forms correctly. Thanks to KStringInflector, Nooku translates back and forth between most English words.

It even knows words like "person" is singular, where "people" is its plural form. Similarly, "index" is the singular form of the plural "indices".

Using Template Shortcuts

The Framework provides some handy shortcuts and syntactical sugar for use in our view templates. They help keep templates clean and function names a little more relevant to the designer. Here are some of them:

Let try some in our example. Change the ul list in above example to:

    <? foreach($items as $item) : ?>
            <?=translate('ID'). ': ' . $item->id?>.
            <?=translate('Title'). ': ' . $item->title?>
            <?=translate('Text'). ': ' . $item->text?>
    <? endforeach; ?>

If we had some date information defined in our database for each item, i.e. $item->created_on we could use the helper shortcut to load the date helper and make that information easier to read for us humans.

<?= helper('date.humanize', array('date' => $activity->created_on )); ?>

Also, when we have a singular Item view ready we could use the route shortcut to help us build our urls.

  <a href="<?= route('view=item&id='. $item->id ) ?>">
            <?= $item->title ?>

All of the shortcuts are there to help you "Write Less Code". Mastering them will help you produce templates faster that are ultimately easier to read.
