Question

是否有一个EE2标签产生一个独特的身份识别器? 或者,我是否有必要把一项PHP的号召放在一边,以获得理想的独特身份? 感谢。

无。这将要求你自己制造假肢、推广或模块。但这很简单。

我的建议是建立一个plugin 。

Create a folder named guid in your expressionengine/third_party folder.
In that folder, create a file called pi.guid.php with the following content:

<?php if ( ! defined( BASEPATH )) exit( No direct script access allowed );

$plugin_info = array(
     pi_name        =>  Uniqid ,
     pi_version         =>  0.1 ,
     pi_author      =>  John Doe ,
     pi_author_url      =>  http://example.org/ ,
     pi_description     =>  Returns uniqid() with parameters ,
     pi_usage       => Guid::usage()
);


class Guid {
            
    public function __construct()
    {
        $this->EE =& get_instance();
    }
    
    public function uniqid()
    {
        $prefix = $this->EE->TMPL->fetch_param( prefix );
        $more_entropy = (strtolower($this->EE->TMPL->fetch_param( more_entropy )) == "true") ? TRUE : FALSE;
        
        return uniqid($prefix, $more_entropy);
    }
    
    public static function usage()
    {
        ob_start();  ?>

        Simple use:

    {exp:guid:uniqid}

        Parameter use:

    {exp:guid:uniqid prefix="yourprefix"}
    {exp:guid:uniqid more_entropy="true"}
    {exp:guid:uniqid prefix="yourprefix" more_entropy="true"}
    <?php
        $buffer = ob_get_contents();
        ob_end_clean();

        return $buffer;
    }    
}

There you go, your very own plugin to create uniqid() through tags.
The use?

{exp:guid:uniqid prefix="yourprefix"}
{exp:guid:uniqid more_entropy="true"}
{exp:guid:uniqid prefix="yourprefix" more_entropy="true"}

Awesome, right?
I love EE...

没有EEE的固定标签来生产一个独一无二的ID,即编号。
