Sometimes you need to hack the order the source code is going to be rendered in a view:<\/p>\n
– You want an extra piece of CSS that only aplies to that view, so you think it's not worth creating a single CSS file and including in your mashed file<\/p>\n
– You need the same as above for javascript<\/p>\n
– Your mind has not completely grasped the way to organize code in MVC \ud83d\ude42<\/p>\n
<\/p>\n
<\/p>\n
Here's a way to do it:<\/p>\n
<\/p>\n
in your view you add something like this:<\/p>\n
<?php View::start_buffer('head_end'); ?>\n<style>\n ::-moz-selection {\n background: #b3d4fc;\n text-shadow: none;\n }\n\n<\/style>\n<?php View::end_buffer('head_end'); ?><\/pre>\n <\/p>\n
Then, by taking advantage of the wonderful cascading file system that Kohana gives you, you create a View.php class in your application folder that will need to extend the render() function (I'm just adding the relevant changes for this to work; you can have your own extra sauce):<\/p>\n
<\/p>\n
class View extends Kohana_View\n{\n static public $buffers = array();\n\n public static function start_buffer($buffer_name)\n {\n self::$buffers[$buffer_name] = '';\n ob_start();\n }\n\n public static function end_buffer($buffer_name)\n {\n self::$buffers[$buffer_name] = ob_get_clean();\n }\n\n public function render($file = NULL)\n {\n $rendered = parent::render($file);\n\n if (! empty(self::$buffers['head_end']))\n {\n $rendered = str_replace('<\/head>', self::$buffers['head_end'] . '<\/head>', $rendered);\n }\n return $rendered;\n }\n\n}<\/pre>\n <\/p>\n
The buffer names are completely arbitrary, you can make them any way to want.<\/p>\n
I leave up to you to improve the way each buffer will be mapped to different locations in the source code.<\/p>\n
