symfony: page navigation links

pagination helper in the code snippets section of symfony’s website.

the code is modified to include <ul> and <li> tags and to correctly parse uri when passed as routing rule:

PHP:

	`function page_navigation($pager, $uri)`
	`{`
	`$pages = array();`

	`if ($pager->haveToPaginate())`
	`{`
	`$uri .= (preg_match('/\?/', $uri) ? '&' : '?').'page=';`

	`// first / prev links`
	`$pages[] = link_to('« First', $uri . '1');`
	`$pages[] = link_to('< Prev', $uri . $pager->getPreviousPage());`

	`// pages one by one`
	`$links = array();`
	`foreach ($pager->getLinks() as $page)`
	`{`
	`$pages[] = link_to_unless($page == $pager->getPage(), $page, $uri.$page);`
	`}`

	`// next / last links`
	`$pages[] = link_to('Next >', $uri.$pager->getNextPage());`
	`$pages[] = link_to('Last »', $uri.$pager->getLastPage());`
	`}`

	`return '<ul><li>' . implode('</li><li>', $pages) . '</li></ul>';`
	`}`

save the file as PaginationHelper.php in project/root/lib/helper or apps/application/lib/helper.

edit template file:

Code:

<?php echo use_helper('Pagination') ?>
<?php echo pager_navigation($page, '@routing') ?>
