DedeCMS tag customization guide to make your website unique!

DedeCMS is a powerful and flexible open source content management system. It provides rich template tags and plug-in extension functions, which can help website administrators quickly build personalized websites. . However, in the process of building a website using DedeCMS, sometimes it is found that the existing tags cannot meet specific needs, and then tag customization is required. This article will introduce how to customize labels in DedeCMS, as well as specific code examples.

1. Determine the requirements

Before customizing labels, you first need to clarify the functions or effects to be achieved. For example, suppose we need a tag named "custom_tag" to insert custom advertising code into the article content. Specific needs can be adjusted according to actual conditions.

2. Write the tag file

First, find the include directory in the root directory of DedeCMS, and then create a new file named "tag_custom_tag.class.php" in the include directory for Write code for custom tags. The code example is as follows:

<?php
if(!defined('DEDEINC')) exit('Request Error!');

class tag_custom_tag
{
    public $dsql;
    
    public function __construct()
    {
        $this->dsql = $GLOBALS['dsql'];
    }
    
    public function getHtml($atts, $content)
    {
        $adCode = "<div>这里是自定义的广告代码</div>";
        return $adCode;
    }
}
?>

The above code defines a class named "tag_custom_tag", which contains a method named "getHtml", which is used to generate and return the output content of the custom tag. In this example, we simply return a fixed advertising code. In actual applications, dynamic content can be generated based on demand.

3. Register tags

Next, we need to register custom tags in DedeCMS so that they can be called in the template. Find the include/tag/lib_tag.php file in the root directory of DedeCMS, edit the file, and add the following code to the end of the file:

$custom_tag = LoadTag('custom_tag');
$_addfield = Array('autoindex','typeid','keyword','totalnum');
$_ENV['_arclistEnv'] = array();
$pv = new View(30);
$pv->SetSource($arcTag->GetResult());
$pv->SetTemplet(__DIR__.'/templets/tag_custom_tag.htm');
$pv->Display();

4. Write the template file

Finally, we need Write a template file to call the custom tag. Create a new file named "tag_custom_tag.htm" in the templets directory of DedeCMS with the following content:

{dede:custom_tag /}

5. Using custom tags

At this point, we have completed the custom tags custom made. The newly created tags can now be used in post templates. Insert "{dede:custom_tag /}" into the article content to display customized ad code.

Through the above steps, we successfully implemented the process of customizing a custom label in DedeCMS. In this way, we can easily extend the functionality of DedeCMS to make the website more personalized and distinctive. I hope this article will be helpful to everyone when using DedeCMS for website construction!
