1. If it is a list page, use the following code:

[field:id runphp='yes']
global $cfg_cmspath;
$tags = GetTags(@me);
$revalue = '';
$tags = explode(',', $tags);
foreach($tags as $key => $value){
            if($value){
                $revalue .= &#39;<a href="&#39;.$cfg_cmspath.&#39;/tags.php?/&#39;.$value.&#39;/">&#39;.$value.&#39;</a> &#39;;
   }
  }
@me = $revalue;
[/field:id]

2. If it is a content page, use the following code ：

{dede:field.id runphp='yes'}
global $cfg_cmspath;
$tags = GetTags(@me);
$revalue = '';
$tags = explode(',', $tags);
foreach($tags as $key => $value){
            if($value){
                $revalue .= &#39;<a href="&#39;.$cfg_cmspath.&#39;/tags.php?/&#39;.$value.&#39;/">&#39;.$value.&#39;</a>, &#39;;
   }
  }
@me = $revalue;
{/dede:field.id}

Code explanation

In fact, only three knowledge points are used here:

1. Use the built-in GetTags function to obtain the TAG list corresponding to the document;

2. Split the obtained value into an array using the half-width comma (,) as the standard;

3. Loop through the array elements, output the corresponding value and add a link;

At the same time, for better compatibility, the global $cfg_cmspath; method is also used here to load the program installation directory in the basic system parameters, which is used to automatically be compatible with sites installed in subdirectories when attaching links.
