[Extension] EClientScript

Extension download:



I have found another extension created by Vince, but it is too complex and there are many bugs during my usage.


This extension just extend from {link: CClientScript} using few codes, it will allow you to automatically combine all script files and css files into a single (or several) script or css files. Basically this will reduce the HTTP calls for resources files by merging several resources files into a single (or more) files. It can automatically detect the required list of files, and generate a unique filename hash, so boldly ease of use.

Css Files:

CSS files are merged based on there media attribute, background images with a relative path in file can also be displayed correctly.

Script files:

Script files are merged based on their position, If you use the ‘CClientScript::POS_HEAD’ you will end up with a single file for all the script files you’ve used on that page. If you use ‘CClientScript::POS_HEAD’ and ‘CClientScript::POS_END’ for example then you’ll end up with two files for each page on that request, Since those resources are located in different positions.

Hi! I try use in my project ECLientScript and got:

Fatal error: Maximum execution time of 60 seconds exceeded in D:\usr\…\protected\extensions\EClientScript\EClientScript.php on line 314

Yii version 1.4

all js & css files placed in js/ css/ directories

Try to turn off ‘optimizeScriptFile’, set this options to false.

because the optimization is called via google compiler.

Fatal error: Maximum execution time of 300 seconds exceeded in \www\protected\extensions\minify\EClientScript.php on line 316

(combineCssFiles=true, all other options=false)

I also wanted a gzip version of this, so here is my modification.

add the public var to the class


 * @var boolean if a gzip version of the files should be created


public $gzip = false;

create a new private method


 * GZIP a file


 * @param $path The file to gzip

 * @return boolean


private function gzipFile($path) {

	$zp = gzopen($path.'.gz', "w6");

	if ($zp) {

		gzwrite($zp, file_get_contents($path));

		return gzclose($zp);

	} else {

		return false;




if ($this->gzip) {



in combineCssFiles() and combineScriptFiles() after the line with:

file_put_contents($fpath, $fileBuffer);

now in your config file you can add

‘gzip’ => true / false to enable/disable the gzip

Great extension hightman ^_^

Hi!! Thank you for your great extension.

I try it and it works perfect! But then I use it with optimizeScriptFiles I have some errors in my output javascript files. I tried to use JSMin instead JSMinPlus and in works without errors. Maybe you can change your code or make optimizeScriptFiles to be protected.

Thank you!!

Hey This is worked for me,

changed in



// application components

‘clientScript’ => array(

	  'class' => 'ext.ExtendedClientScript.ExtendedClientScript',

	  'combineCss' => true,

	  'compressCss' => false,

	  'combineJs' => false,

	  'compressJs' => false,


//(combineCssFiles=true, all other options=false)
