Zend_View的常用方法


public function __construct($config = array())




构造函数参数
例如


array(
 'escape' => array(),
 'encoding' => array(),
);




常见key：
escape、encoding、basePath、basePathPrefix、scriptPath、helperPath、 helperPathPrefix、filterPath、filterPathPrefix、filter

public function getEngine() Return the template engine object
public function init()初始化函数


/**
* Given a base path, sets the script, helper, and filter paths relative to it
*
* Assumes a directory structure of:
* <code>
* basePath/
*   scripts/
*   helpers/
*   filters/
* </code>
*
* @param string $path
* @param string $prefix Prefix to use for helper and filter paths
* @return Zend_View_Abstract
*/
public function setBasePath($path, $classPrefix = 'Zend_View')
/**
* Given a base path, add script, helper, and filter paths relative to it
*
* Assumes a directory structure of:
* <code>
* basePath/
*   scripts/
*   helpers/
*   filters/
* </code>
*
* @param string $path
* @param string $prefix Prefix to use for helper and filter paths
* @return Zend_View_Abstract
*/
public function addBasePath($path, $classPrefix = 'Zend_View')
public function addScriptPath($path)Adds to the stack of view script paths in LIFO order.
public function setScriptPath($path) Resets the stack of view script paths.
public function getScriptPath($name)Return full path to a view script specified by $name
public function getScriptPaths()Returns an array of all currently set script paths
public function addHelperPath($path, $classPrefix = 'Zend_View_Helper_')Adds to the stack of helper paths in LIFO order.
public function setHelperPath($path, $classPrefix = 'Zend_View_Helper_')Resets the stack of helper paths.
public function getHelperPath($name) Get full path to a helper class file specified by $name
public function getHelperPaths()Returns an array of all currently set helper paths
public function getHelper($name) Get a helper by name
public function getHelpers()Get array of all active helpers
public function getAllPaths() Return associative array of path types => paths
public function setEscape($spec)
/**
* Assigns variables to the view script via differing strategies.
*
* Zend_View::assign('name', $value) assigns a variable called 'name'
* with the corresponding $value.
*
* Zend_View::assign($array) assigns the array keys as variable
* names (with the corresponding array values).
*
* @see  __set()
* @param string|array The assignment strategy to use.
* @param mixed (Optional) If assigning a named variable, use this
* as the value.
* @return Zend_View_Abstract Fluent interface
* @throws Zend_View_Exception if $spec is neither a string nor an array,

*/
public function assign($spec, $value = null)




在controller的action可以通过assign传递参数到视图脚本。
例如


$this->view->assign('roles', $roles);
$this->view->assign('num', $num);
$this->view->assign('a', $a);




或者也可以用


$this->view->roles=$roles;
$this->view->a=$a;
public function render($name) Processes a view script and returns the output.
public function escape($var):Escapes a value for output in a view script.
public function setEncoding($encoding) Set encoding to use with htmlentities() and htmlspecialchars()
public function getEncoding() :Return current escape encoding




视图脚本文件中的常见用法：
获取传递过来的值


$this->roles




使用一些常见的助手方法：


$this->baseUrl();
$this->url();
$this->paginationControl();
$this->partial()




视图常见用法举例
在bootstrap初始化view或者controller的init文件中


/**
 * Initialize the common view helper
 */
protected function _initViewHelper()
{
  $boot=$this->bootstrap('View');
  $view = $boot->getResource('View');
        $view->setHelperPath('Sql/View/Helper', 'Sql_View_Helper');
}



action中


/**
 *
 * @return void
 */
public function listAction()
{
  $this->view->assign('data', $data);
}




视图文件
