[英]Wordpress / PHP - Do a single shortcode
In WP you can filter shortcodes from a string and execute their hooked functions with do_shortcode($string)
. 在WP中,您可以从字符串中过滤短代码,并使用
do_shortcode($string)
执行其钩子函数。
Is it possible to filter a single shortcode, instead of all registered shortcodes? 是否可以过滤单个短代码而不是所有已注册的短代码?
for example I need a few shortcodes to be available for comment posters as well, but not all for obvious reasons :) 例如,我需要一些短代码来提供评论海报,但不是全部因为显而易见的原因:)
function do_shortcode_by_tags($content, $tags)
{
global $shortcode_tags;
$_tags = $shortcode_tags; // store temp copy
foreach ($_tags as $tag => $callback) {
if (!in_array($tag, $tags)) // filter unwanted shortcode
unset($shortcode_tags[$tag]);
}
$shortcoded = do_shortcode($content);
$shortcode_tags = $_tags; // put all shortcode back
return $shortcoded;
}
This works by filtering the global $shortcode_tags
, running do_shortcode()
, then putting everything back as it was before. 这可以通过过滤全局
$shortcode_tags
do_shortcode()
,运行do_shortcode()
,然后将所有内容恢复原样。
Example use; 使用示例;
$comment = do_shortcode_by_tags($comment, array('tag_1', 'tag_2'));
This will apply the shortcode tag_1
and tag_2
to the comment. 这会将短代码
tag_1
和tag_2
应用于评论。
