no more cache – force the reload based on the file date [ 974 views ]
Goal: avoid cache in case of changed files
The cache is our friend in case of old files. With this code I can use the cache based on my file date.
<link href="css/main.css?<?php echo(filemtime("css/main.css")); ?>" rel="stylesheet" type="text/css" />
the result is
<link href="css/main.css?1402529381" rel="stylesheet" type="text/css">
In a little bit friendly shape:
...
class no_cache{
public static function css($fileName){
echo('<link rel="stylesheet" type="text/css" href="'.self::get_file($fileName).'" media="screen"/>');
}
public static function js($fileName){
echo('<script src="'.self::get_file($fileName).'"></script>');
}
public static function file($fileName){
echo(self::get_file($fileName));
}
public static function get_file($fileName){
return $fileName . '?' . filemtime($fileName);
}
}
...
<?php
no_cache::css('css/main.css');
no_cache::js('js/jquery-1.7.1.js');
no_cache::js('js/main.js');
?>
...
/* and the output is */
<link rel="stylesheet" type="text/css" href="css/main.css?1403178760" media="screen">
<script src="js/jquery-1.7.1.js?1368082485"></script>
<script src="js/main.js?1402517230"></script>
...
Shorter, smarter…
Call the no_cache class like
css: no_cache::css('css_file_path');
js: no_cache::js('js_file_path');
file: no_cache::file('file_path');
