Hi everyone,
Today, I introduce an idea to assign default values to $template in your
template throgh view's attributes.
This can be implemented simply like this:
// ProjectBaseView.class.php
<?php
class ProjectBaseView extends AgaviView
{
public function loadLayout($layoutName = null)
{
$parameters = parent::loadLayout($layoutName);
$assigns = array_key_exists('default_assigns', $parameters) ?
(array)$parameters['default_assigns'] : array();
foreach( $assigns as $key=>$value) {
$this->setAttribute($key, $value);
}
return $parameters;
}
/**
some codes here....
**/
}
?>
// EOF
Only this :)
And you can set default values following:
// a layout setting in output_type.xml
<layout>
<layers>
<layer name="content" />
<layer name="decorator">
<parameter name="template">%core.template_dir%/Master</parameter>
</layer>
</layers>
<parameter name="default_assigns">
<parameter name="allow_index">false</parameter>
<parameter name="author">MugeSo</parameter>
<parameter name="style_sheets"><!-- an array parameter -->
<parameter>css/base.css</parameter>
<parameter>css/default.css</parameter>
</parameter>
</parameter>
</layout>
// End of layout
Now you can use these values in your templates ;)
For example, using them in Master template:
// Master.php
<html>
<head>
<meta name="author" content="<?php echo $template['author']; ?>" />
<meta name="robots" content="<?php if($template['allow_index']):
?>index<?php else: ?>noindex<?php endif;?>,follow" />
<?php foreach($template['style_sheets'] as $style_sheet): ?>
<link rel="stylesheet" href="<?php echo $style_sheet; ? />"
type="text/css">
<?php endforeach; ?>
<base href="<?php echo $ro->getBaseHref();?>" />
</head>
<body>
<?php echo $inner; ?>
</body>
</html>
// EOF
Above code works without any notice even if you don't set author,
allow_index or style_sheets in your View, though you needed to set them
in all of your Views or to check $template with
isset($template['some_key']) or array_key_exists('some_key', $template)
in your template before.
Of course, you are also allowed to overwrite some of them like this:
// executeHtml in your view
function executeHtml(AgaviRequestDataHolder $rd)
{
$this->loadLayout();// you can use setupHtml here too ;)
$this->setAttribute('allow_index', true);
$this->setAttribute('author', 'David Zulke');
$this->appendAttribute('style_sheets', 'css/other.css');
/** some codes here **/
}
// end of executeHtml
Thank for your reading :)
enjoy your weekend,
from Japan,
