// Parses the template and returns the string of a processed page
$this->processPage($options = array()); // Needs at least page_number
offset in $options array
// Protected methods, although very useful
// Parse the template of a given page and return the processed template
$this->_parseTemplate($options = array());
// Parse the url mask to return the correct template depending of the
options sent
// Already process the mask replacements assigned
$this->_parseUrlTemplate($options = array());
// Parse the mask replacements of a given page
$this->_parseReplacementsTemplate($options = array());
// Parse the url mask of a given page and return the processed url
$this->_parseUrl($options = array());
// Parse the mask replacements, changing from to-be replaced mask with new
masks/values
$this->_parseMaskReplacements($str);
Now that you have a small tip of useful methods to be used when extending
Doctrine_Pager_Layout, it's time to see our implemented class:
class PagerLayoutWithArrows extends Doctrine_Pager_Layout
{
public function display($options = array(), $return = false)
{
$pager = $this->getPager();
$str = '';
// First page
$this->addMaskReplacement('page', '«', true);
$options['page_number'] = $pager->getFirstPage();
$str .= $this->processPage($options);
// Previous page
$this->addMaskReplacement('page', '‹', true);
$options['page_number'] = $pager->getPreviousPage();
$str .= $this->processPage($options);
// Pages listing
$this->removeMaskReplacement('page');
$str .= parent::display($options, true);
// Next page
$this->addMaskReplacement('page', '›', true);
$options['page_number'] = $pager->getNextPage();
$str .= $this->processPage($options);
// Last page
$this->addMaskReplacement('page', '»', true);
$options['page_number'] = $pager->getLastPage();
$str .= $this->processPage($options);
