Modify a template output

Ok, what I did finally is a mix between layouts and templates.

• I modified my template, leaving only Perch fields:

<perch:content id="activity" title="true" type="text" label="Activity" help="Activity description" />
<perch:content id="date" type="date" label="Date" help="Activity date" />

• I created a layout named calendar.php using the perch_content_custom function with skip-template and here is where I finally manage the calendar output:

<?php

$calendar = perch_content_custom('Calendar', array(
    'skip-template' => true
));

foreach($calendar as $activity) {
    $date = explode('-', $activity['date']);
    $month = jdmonthname($date[1], 0);
?>
    <h1><?=$month?></h1>
    <p><?=$activity['activity']?></p>
<?php
}

• Finally on all my pages where I need the calendar, I included the layout:

perch_layout('calendar');

So I'm using the Perch templates for managing the fields and the layout for presenting the calendar.

I don't know if this is the right way, I will wait a answer from experienced people to get some feedback.

Agustín, you can use the "format" tag attribute, since you want to manipulate a date, the date field docs has some examples

Thanks for the tip Andrés!

I was writing:

But, if I need for example extract the month and year from a date field, and display the values in different HTML tags. I think the Perch template system it not help in those cases.

And I answer to my self according the docs we can re-use an ID of a field and use the content in different places on a template.

But my above example mixing templates and layouts, may be useful for other cases, I think, maybe if you need more flexibility than the templates gives us.

The output can be i18n? I need the month in Spanish.
