Every so often I find it necessary to overwrite certain styles or implement
styles or js functionality specific to certain pages in my app. For some
projects my app application-wide stylesheets and js can get really big
really fast and I find it more manageable to break them down into smaller
files and only call them when needed. I put together a really simple Asset
Helper that replaces my Html->css and Html->script and incorporates the
assets based on controller/actions. The comment was made recently that it
was a really bad idea and would create issues as the app grows larger and
traffic to the app increases. They didn't elaborate on the comment so now
it leaves me wondering.
I can't see where it would create any issues to speak of. My css and js
directories contain a fair amount of files but is still extremely small by
comparison so I don't really see any type of significant performance hit.
Am I overlooking something here?
// AssetHelper.php
App::uses('AppHelper', 'View/Helper');
App::uses('Folder', 'Utility');
Class AssetHelper extends AppHelper{
public $helpers = array('Html');
public function css($css_array = null){
$css = new Folder(WWW_ROOT . 'css');
$css_files = $css->find('.*\.css');
if ($this->params['controller'] == 'pages'){
$file = "pages_{$this->params['pass'][0]}";
} else {
$file =
$this->params['controller'].'_'.$this->params['action'];
}
if (in_array($file.'.css', $css_files)){
array_push($css_array, $file);
}
return $this->Html->css($css_array);
}
public function js($js_array = null){
$js = new Folder(WWW_ROOT . 'js');
$js_files = $js->find('.*\.js');
if ($this->params['controller'] == 'pages'){
$file = "pages_{$this->params['pass'][0]}";
} else {
$file =
$this->params['controller'].'_'.$this->params['action'];
}
if (in_array($file.'.js', $js_files)){
array_push($js_array, $file);
}
return $this->Html->script($js_array);
}
}
