How do I set id prefixes used by Zend_View_Helper_Navigation_XXX
When I render a Zend_Nagivation
instance in my view, by default the anchor tags have id's assigned with the prefix of the view helper, followed by a dash, and then the page's id.
Examples of Page 1's anchor id (all using the same Zend_Nagivation
instance):
Zend_View_Helper_Navigation_Menu
= "menu-1"Zend_View_Helper_Navigation_Breadcrumbs
= "breadcrumbs-1"My_View_Helper_Navigation_MyMenu
= "mymenu-1"
This is perfect for most cases, but I'd like to set that prefix manually, and I can't find a way to do it.
Solution
Specifying the prefix can be accomplished by adding the fo开发者_如何学JAVAllowing code, and then calling setIdPrefix()
when rendering:
class My_View_Helper_Navigation_MyMenu extends Zend_View_Helper_Navigation_Menu
{
protected $_idPrefix = null;
/**
* Set the id prefix to use for _normalizeId()
*
* @param string $prefix
* @return My_View_Helper_Navigation_MyMenu
*/
public function setIdPrefix($prefix)
{
if (is_string($prefix)) {
$this->_idPrefix = $prefix;
}
return $this;
}
/**
* Use the id prefix specified or proxy to the parent
*
* @param string $value
* @return string
*/
protected function _normalizeId($value)
{
if (is_null($this->_idPrefix)) {
return parent::_normalizeId($value);
} else {
return $this->_idPrefix . '-' . $value;
}
}
}
The culprit is Zend_View_Helper_Navigation_HelperAbstract::_normalizeId()
for which I see no other solution than to create your own custom version of each navigation view helper you require.
