Where should I locate logic related to layout in Zend Framework?
I need to customize the attributes of my body tag. Where should I locate the logic? In a Base Controller, view Helper ?
This should be the layout
<?=$this->doctype() ?>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
...
</head>
<body<?=$this->bodyAttrs?>> <!-- or <?=$this->bodyAttrs()?> -->
...
</body>
</html>
And this should be the variables declaration in controllers
class Applicant_HomeController extends Zend_Controller_Action
{
public function indexAction()
{
$this->idBody = "someId1";
$this->classesBody = array("wide","da开发者_StackOverflowrk");
}
public function loginAction()
{
$this->idBody = "someId2";
$this->classesBody = array();
}
public function signUpAction()
{
$this->idBody = "someId3";
$this->classesBody = array("no-menu","narrow");
}
}
This is the function where the attributes are concatenated.
/**
* @param string $idBody id Attribute
* @param array $classesBody class Attribute (array of strings)
*/
protected function _makeBodyAttribs($idBody,$classesBody)
{
$id = isset($idBody)?' id="'.$idBody.'"':'';
$hasClasses = isset($classesBody)&&count($classesBody);
$class = $hasClasses?' class="'.implode(' ',$classesBody).'"':'';
return $id.$class;
}
I need the last glue code.
Got one better for ya:
<?php
class My_View_Helper_Attribs extends Zend_View_Helper_HtmlElement
{
public function attribs($attribs) {
if (!is_array($attribs)) {
return '';
}
//flatten the array for multiple values
$attribs = array_map(function($item) {
if (is_array($item) {
return implode(' ', $item)
}
return $item;
}, $attribs);
//the htmlelemnt has the build in function for the rest
return $this->_htmlAttribs($attribs)
}
}
in your controller:
public function indexAction()
{
//notice it is $this->view and not just $this
$this->view->bodyAttribs= array('id' => 'someId', 'class' => array("wide","dark"));
}
public function loginAction()
{
$this->view->bodyAttribs['id'] = "someId2";
$this->view->bodyAttribs['class'] = array();
}
in your view script:
<body <?= $this->attribs($this->bodyAtrribs) ?>>
加载中,请稍侯......
