pagination link stylin' extension
Development and Programming
Hi,
I made a simple extension to add a css class to pagination links. Downside is a special hook needs to be added to the core.paginate.php file at the top of the show_links() method just after the global definitions for the method.
Add the following to core.paginate.php at line 79
// -------------------------------------------
// 'paginate_edit_object' hook.
// - Rewrite the show_links function in the core file and change variables
// ADDED BY HCCDevelopment 08/19/08 Brian Greenacre
//
if ($EXT->active_hook('paginate_edit_object') === TRUE)
{
$edata = $EXT->universal_call_extension('paginate_edit_object', $this);
if ($EXT->end_script === TRUE) return;
}
//
// -------------------------------------------Here’s the extension code.

$EXT->end_script = FALSE;
$class = ( $TMPL->fetch_param('link_class') ) ? ' class="' . $TMPL->fetch_param('link_class') . '"' : '';
$paginate_obj->next_div_o .= '<span>';
$paginate_obj->next_div_c .= '</span>';
$paginate_obj->num_div_o .= '<span>';
$paginate_obj->num_div_c .= '</span>';
$paginate_obj->cur_div_o .= '<span>';
$paginate_obj->cur_div_c .= '</span>';
$paginate_obj->last_div_o .= '<span>';
$paginate_obj->last_div_c .= '</span>';
$paginate_obj->prev_div_o .= '<span>';
$paginate_obj->prev_div_c .= '</span>';
return true;
}
}
?>
As Brian was saying unfortunately the core.paginate.php needs to be hacked to add the hook, so if you upgrade or reinstall this would need to be redone every time. Maybe the powers to be could add this hook in the next build 😉
To use this extension add the link_class parameter to the weblog tag like so:
{exp:weblog:entries pagination="top" link_class="my_pagination_class"}
Then in your CSS you can define the class:
.my_pagination_class a { color: #000; border: solid 1px #333; etc…….}
Hope this helps.
