计算帖子中使用 WordPress 简码的次数 [英] Count the number of times a WordPress shortcode is used in a post
本文介绍了计算帖子中使用 WordPress 简码的次数的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我有以下 WordPress 短代码功能:
I have the following WordPress shortcode function:
function wp_shortcode() {
static $i=1;
$return = '['.$i.']';
$i++;
return $return;
}
add_shortcode('shortcode', 'wp_shortcode');
这很好用.每次在文章中调用函数时,$i
变量都会增加.所以对于
This works fine. The $i
variable gets incremented each time the function is called in the article. So for
[shortcode][shortcode][shortcode][shortcode]
输出符合预期
[1][2][3][4]
但是
如果文章超过一页,则计数器会在下一篇文章页面上重置.所以对于:
if the article has more than one page, than the counter resets on the next article page. So for:
[shortcode][shortcode][shortcode][shortcode]
<!--nextpage-->
[shortcode][shortcode][shortcode][shortcode]
输出是
[1][2][3][4]
<!--nextpage-->
[1][2][3][4]
而不是想要的输出:
[1][2][3][4]
<!--nextpage-->
[5][6][7][8]
无论如何要改变这个?
推荐答案
因此,在对 @diggy 的想法进行了更多研究后,对 the_content 进行预处理并将 $atts 添加到短代码渲染之前,我想出了这个:
So after researching a bit more @diggy's idea with pre processing the_content and adding the $atts to the shorcodes before the shortcodes are rendered, I came up with this:
function my_shortcode_content( $content ) {
//check to see if the post has your shortcode, skip do nothing if not found
if( has_shortcode( $content, 'shortcode' ) ):
//replace any shortcodes to the basic form ([shortcode 1] back to [shortcode])
//usefull when the post is edited and more shortcodes are added
$content = preg_replace('/shortcode .]/', 'shortcode]', $content);
//loop the content and replace the basic shortcodes with the incremented value
$content = preg_replace_callback('/shortocode]/', 'rep_count', $content);
endif;
return $content;
}
add_filter( 'content_save_pre' , 'my_shortcode_content' , 10, 1);
function rep_count($matches) {
static $i = 1;
return 'shortcode ' . $i++ .']';
}
