thinkphp Dynamic Version Control

Dynamic versioning can be implemented based on timestamps, but in that case, the version-controlled file is re-downloaded every time the page is opened, and if your page itself is open, it will be slow.

This will undoubtedly result in a poor user experience.

But if you manually add a version after each reference file, it's obviously a stupid thing to do if the page is more, so we can do this:

(1) Define the public module in the Portal file:

Define (' Common_path ', './common/');

Then cut out the common in the home folder and place it in the same directory as the portal file.

(2) Configure an array in common-->conf-->config.php:

<?php
Return Array (
CSS version control
' Cssversion ' = ' 1.0 ',
' Cssversionid ' = ' 1.0 ',
JS version control
' Jsversion ' = ' 1.0 ',
' Jsversionid ' = ' 1.0 ',
);

(3) introducing in the controller

<?php
namespace Home\controller;
Use Think\controller;
Class Indexcontroller extends Controller {
Public Function index () {
/* Version control */
$config = require (Common_path. ') Conf/config.php ');

$this->assign (' Cssversionid ', $config [' Cssversionid ']);

$this->assign (' Jsversionid ', $config [' Jsversionid ']);
/* Page Display */
$this->display ();
}
}

Of course all assign must be placed in $this->display (); front. In thinkPHP3.2.3, you can also write:

<?php
namespace Home\controller;
Use Think\controller;
Class Indexcontroller extends Controller {

Public Function __construct () {/* Versioning control */

Parent::__construct ();

$config = require (Common_path. ') Conf/config.php ');

$this->assign (' Cssversionid ', $config [' Cssversionid ']);

$this->assign (' Jsversionid ', $config [' Jsversionid ']);
}

Public Function index () {
/* Page Display */
$this->display ();
}
}

(4) The HTML page allows you to introduce

<link rel= "stylesheet" type= "Text/css" href= "__public__/css/page/index.css?v={$cssVersionid}" >

<script src= "__public__/js/page/index.js?v={$jsVersionid}" ></script>

This way, every time there is an update, you only need to manually change the version on the config.php, and can only update CSS or JS one of them.
