Template Tags/get the tag list
Материал из WordPress Wiki
Содержание |
Description
Generates a HTML string of the tags associated with the current post. The name of each tag will be linked to the relevant 'tag' page. You can tell the function to put a string before and after all the tags, and in between each tag. This tag must be used inside 'The Loop'.
Usage
%%% <?php $tag_list = get_the_tag_list( $before = 'before', $sep = 'seperator', $after = 'after' ) ?> %%%
This function does not display anything - if you want to put it straight onto the page, you should use echo (get_the_tag_list()). Alternatively, you can assign it to a variable for further use by using $foo = get_the_tag_list().
The variables are all optional, and should be placed in the order 'before', 'separator', 'after'. You can use HTML inside each of the fields.
Example
A Basic Example
This outputs the list of tags inside a paragraph, with tags separated by commas.
<?php
echo get_the_tag_list('<p>Tags: ',', ','</p>');
?>
This would return something like.
<p> Tags: <a href="tag1">Tag 1</a>, <a href="tag2">Tag 2</a>, ... </p>
A Slightly More Complex Example
This checks if the post has any tags, and if there are, outputs them to a standard unordered list.
<?php
if(get_the_tag_list()) {
get_the_tag_list('<ul><li>','</li><li>','</li></ul>');
}
?>
This will return something in the form:
<ul> <li><a href="tag1">Tag 1</a></li> <li><a href="tag2">Tag 2</a></li> ... </ul>
You can add classes and styles with CSS, as necessary.
