Question

Magazine.ss

  <% with $Magazine %>
    <h1>$Title</h1>
    <iframe src="http://docs.google.com/viewer?url={$Document.AbsoluteURL}&embedded=true" width="100%" height="842"></iframe>
  <% end_with %>

如果您检查上述代码，则会将网址打印为＆＃39; http://masapulari.com/assets/Uploads/dummy.pdf。 Magazine是一个DataObject类，Document是File Type，如下所示。有没有办法打印$ Document.AbsoluteURL的urlencode？

class Magazine扩展了DataObject {

private static $db = array(
  'Title'=>'VarChar',
  'Date' => 'Date',
);

private static $has_one = array(
  'Photo' => 'Image',
  'Document' => 'File'
);

}

class Magazine_Controller扩展了Page_Controller {

private static $allowed_actions = array (
    'index','view'
      );

public function init() {
    parent::init();

    // Note: you should use SS template require tags inside your templates 
    // instead of putting Requirements calls here.  However these are 
    // included so that our older themes still work
    Requirements::themedCSS('reset');
    Requirements::themedCSS('layout'); 
    Requirements::themedCSS('typography'); 
    Requirements::themedCSS('form'); 
}   

public function view(){
  $params = $this->getURLParams();
  $id = (int)$params['ID'];

  $data = $this->Magazine($id);   

    return $this->customise(array(
        'Magazine'=>$data
    ))->renderWith(array( 'Magazine', 'Page'));       
}

public function Magazine($id){
  $data = DataObject::get_by_id('Magazine',$id);            
    return $data;      
}

}

Answer 1

您可以使用$Document.AbsoluteURL.URLATT对某个字段进行urlencode。

Answer 2

在SilverStripe中，您始终可以在DataObject或Controller上创建新方法。这些方法将自动在模板中可用。

class Magazine extends DataObject {
    private static $db = array(
        'Title' => 'VarChar',
        'Date' => 'Date',
    );
    private static $has_one = array(
        'Photo' => 'Image',
        'Document' => 'File',
    );
    public function EncodedDocumentURL() {
        if ($this->Document() && $this->Document()->exists()) {
            return urlencode($this->Document()->getAbsoluteURL());
        }
    }
}

您可以使用模板中的

：

<% with $Magazine %>
    <h1>$Title</h1>
    <iframe src="http://docs.google.com/viewer?url={$EncodedDocumentURL}&embedded=true" width="100%" height="842"></iframe>
<% end_with %>

Answer 3

我通过添加get function＆＃39; getEncodedURL＆＃39;

解决了这个问题

class Magazine扩展了DataObject {

private static $db = array(
  'Title'=>'VarChar',
  'Date' => 'Date',
);

private static $has_one = array(
  'Photo' => 'Image',
  'Document' => 'File'
);

  public function getEncodedURL() {
  //return '\\' ;
  if ($this->Document() && $this->Document()->exists()) {
      return urlencode($this->Document()->getAbsoluteURL());
  }
  }

  public function getTitle(){
return $this->getField('Title');
  }

  /*
 public function PrintURL() {
 return '\\' ;
 }
 */

}

模板中的

  <% with $Magazine %>
    <h1>$Title</h1>                 
    <iframe src="http://docs.google.com/viewer?url={$EncodedURL}&embedded=true" width="100%" height="842"></iframe>
  <% end_with %>

感谢Zauberfisch指出我正确的方向

使用silverstripe编码网址 - urlencode
